A Slave's Diary – Part 7
By Leslie McCormick
A female bodybuilder becomes a sex slave to a harsh mistress



Part Seven

 The night at the club was a turning point for me.  Until that point, I 
was merely curious in a perverse sort of way about being a sexual slave.  
Drawn by my attraction to Margo, I'd allowed my curiosity to overwhelm 
my common sense.  The drugs Susan had given me had lowered my 
inhibitions to the point where my behavior reverted to my previous 
promiscuous pattern.  I'd thought those days were behind me, buried 
beneath the discipline of bodybuilding and weight training.  I saw now 
that that part of my life hadn't been eradicated, it'd only been in 
hibernation. 
 My parents died in a car accident when I was thirteen years of age.  My 
older sister, Mary Ellen, and I were farmed out to my father's brother.  
My uncle was a change-of-life baby, and therefore considerably younger 
than my father's forty-seven years.  When Mary Ellen and I came to live 
with him and his wife, Jennifer, he was only thirty years old. 
 Like most Irish men, Uncle Mickey drank.  From the time he came home 
from work, until the time he stumbled off to bed, he drank.  Unlike 
other drunks, he wasn't loud or belligerent.  Instead, he grew morose, 
lamenting over his lack of opportunities.  From what I saw, if he had 
drunk less, and worked more, he would have had all the opportunities he 
needed. 
 Aunt Jennifer was twenty-five old, barely out of her teens herself, and 
hardly ready to cope with two teen-aged girls.  Not only was she young, 
but she was an only child.  She wasn't used to the rough tumble give-
and-take of living with siblings.  Our presence in her house completely 
overwhelmed her.  It didn't help that Mary Ellen took an instant and 
lasting dislike to her.  Aunt Jennifer was a slight, pale, pretty girl 
whose ethereal beauty overshadowed everyone else.  Mary Ellen, to be 
generous, was plain-looking.  It was a source of great disappointment to 
her.  She grew to adulthood bitter over her lack of classic beauty.  
Looking at Aunt Jennifer caused envy in Mary Ellen that was close to 
hate. 
 And so because Uncle Mickey drank and Aunt Jennifer was overwhelmed, we 
got to do pretty much whatever we wanted.  For Mary Ellen, that meant 
becoming the most promiscuous girl in the neighborhood.  The decision 
was an easy one for her.  She wanted attention, and found she could 
garner it, however fleetingly, by putting out for the boys.  The fact 
that they talked about her, and that she gained a reputation around the 
neighborhood never bothered Mary Ellen at all.  She was sixteen, and 
already pretty well-developed.  Like our mother, she was tall, and big-
boned.  She stood six feet tall in her stocking feet, and weighed close 
to two hundred pounds.  She wasn't fat.  Far from it.  She was just 
naturally big, with well-developed muscles.  Mary Ellen didn't work out, 
but she was big and strong nonetheless. 
 Because there was little space in the house, we were forced to share a 
room.  Mary Ellen was never ashamed or embarrassed about her body.  She 
liked being nude, and stripped at every opportunity.  I protested at 
first, but after a bare-knuckle fight in which she knocked me senseless, 
I held my tongue.  It was better to let her walk around bare-skinned, 
than to have my ass kicked.  Over time, I grew used to her nudity. 
 One day, just before school let out for the summer, Mary Ellen and Aunt 
Jennifer got into a fight.  It was unseasonably hot, with the 
temperature reaching eighty-five.  As was her custom, Mary Ellen 
stripped off her clothes the moment she got home.  Usually, she wore a 
bathrobe when she walked through the house's common areas, but on this 
day, lulled by the heat, and believing that Aunt Jennifer was out of the 
house, Mary Ellen decided to walk naked from our room to the kitchen for 
some ice water.  Aunt Jennifer, who'd been sunbathing in the back yard, 
came into the kitchen at the same time as Mary Ellen. 
 Aunt Jennifer was normally a calm and placid person, but on this day, 
her entire personality underwent a change.  The sight of Mary Ellen's 
nude body incensed her.  She was a very shy, very private person, and 
the sight of my sister walking around without clothing outraged her.  
She screamed at Mary Ellen to put on some clothes.  Mary Ellen, angry 
and upset at the dressing-down, began yelling in return.  By the time I 
reached the kitchen to investigate the noise, they were standing toe-to-
toe, screaming obscenities at one another.  I wanted to intervene, but I 
was frightened at the intensity of their anger, and so did nothing. 
 Aunt Jennifer was in a rage.  When Mary Ellen refused once again to 
leave the kitchen, Aunt Jennifer slapped her hard across the face. That 
was her first mistake.  It stunned Mary Ellen into momentary silence.  
She hadn't been hit since she was a toddler, and for several seconds, 
she just stood there, and stared at Aunt Jennifer with a look of shock 
on her face.  Then, with a cry of rage, she flung herself at Aunt 
Jennifer. 
 Aunt Jennifer wasn't very big.  She stood at five feet five inches, and 
weighed no more than one hundred twenty-five pounds.  She was petite, 
with almost no breasts to speak of, although she had an ass that was 
beautifully rounded.  I'd often wondered what Uncle Mickey saw in her, 
because I knew that he liked women with big tits.  He'd commented on 
Mary Ellen's chest more than once when he was drunk, saying that he 
wished Aunt Jennifer's were only half as big. 
 When Mary Ellen ripped Aunt Jennifer's bathing suit top from her body, 
I saw what Uncle Mickey meant.  Her tits were tiny, with small, pale 
nipples.  Even at thirteen, mine were bigger.  I nearly laughed out 
loud.  Aunt Jennifer screamed in outrage, and tried to cover her breasts 
with her hands.  That was her second mistake. 
 Mary Ellen fought like a boy.  She balled her fists, and threw a series 
of hard punches that landed on Aunt Jennifer's body.  Stunned by the 
attack, Aunt Jennifer dropped her defenses.  Mary Ellen's fist landed 
squarely on Aunt Jennifer's chin.  The blow staggered my aunt, making 
her stumble and fall backward.  Mary Ellen didn't pause, but went right 
after her, throwing hard rights and lefts.  She concentrated on hitting 
Aunt Jennifer in the torso.  Her fists struck Aunt Jennifer's little 
titties, mashing them against her breastbone, and flattening them out.  
Screaming in pain, Aunt Jennifer tried to fight back.  She threw a 
flurry of punches, although she had no real fight plan.  It was obvious 
that she was only trying to stem Mary Ellen's furious attack. 
 The heat and exertion was making them both sweat.  As she danced around 
Aunt Jennifer, the moisture flew off Mary Ellen in fat droplets.  I 
watched the muscles in her arms and back and buttocks and legs flex and 
relax as she bobbed and weaved, and tried to punch my aunt in 
submission.  I was growing excited watching Mary Ellen and Aunt Jennifer 
fight.  I'd never really taken close notice of how toned and fit my 
sister's body was, nor how big her breasts were.  Mary Ellen wore a size 
36, C cup.  She was proud of her breasts, and liked showing them off.  
They were like mother's, round and firm, with long nipple spikes.  They 
seemed even longer than normal today, and I realized that the reason 
they looked so big was that Mary Ellen was excited by her domination of 
Aunt Jennifer. 
 The fight didn't last long.  Once she recovered from the surprise of 
being attacked, Aunt Jennifer gamely fought back, but she was no match 
for her bigger and stronger stepdaughter.  I could tell she was tiring, 
because she no longer tried to hide her exposed breasts, but was only 
trying to trade punches with Mary Ellen.  Being younger and more 
experienced in fighting, Mary Ellen was winning the fight.  She took aim 
and landed, in quick succession, a hard right and then a left to Aunt 
Jennifer's jaw.  That took the fight out of Aunt Jennifer.  With a sigh, 
she fell to the floor.  Mary Ellen pounced on her, dropping her knee 
into Aunt Jennifer's exposed stomach.  The air whooshed from Aunt 
Jennifer's body, and she folded in on herself.  Mary Ellen kicked Aunt 
Jennifer in the side, then sat down on her chest, her knees pinning Aunt 
Jennifer's arms to the floor.  Aunt Jennifer, crying like a baby, looked 
up fearfully at Mary Ellen. 
 "Get off me," Aunt Jennifer said.  Her pale, shapely legs kicked 
futilely in the air. 
 Mary Ellen slapped her face.  "Shut up, bitch," she said harshly.  "I'm 
in charge here."  She looked up at me, and grinned wickedly.  "Pull her 
bottom off.  I want to look at her cunt." 
 I was doubtful.  "I don't know, Mary Ellen." 
 "Do it, or I'll kick your ass next." 
 I knew better than to argue further.  I went over, grabbed my aunt's 
bathing suit bottom by the waist and tugged them down her legs.  She 
kicked and screamed, but there was nothing she could while Mary Ellen 
sat on her chest. 
 "Get off me," Aunt Jennifer yelled.  "You just wait until your uncle 
gets home tonight." 
 That was definitely the wrong thing to say.  Mary Ellen used both hands 
to slap Aunt Jennifer's face, first the left hand, then the right.  Aunt 
Jennifer's head snapped back and forth like she was watching a tennis 
game. 
 "If you tell Uncle Mickey one word of this," Mary Ellen said 
threateningly, "I'll beat you so badly that you'll think today is a 
picnic.  Do you understand?" 
 Aunt Jennifer's eyes were bright with fear.  There was no doubt in her 
mind that Mary Ellen was serious.  She knew her niece meant what she 
said.  Slowly, she nodded.  Mary Ellen laughed, and then shifted her 
weight from side to side. 
 "Good," she said.  "I'm glad you're seeing things my way.  Get up." 
 Mary Ellen got up, and lifted Aunt Jennifer to her feet by her hair.  
They were both dripping sweat, and their bodies glistened in the late 
afternoon light.  Mary Ellen dragged Aunt Jennifer over to a chair, and 
forced her to sit down. 
 "Now, then," Mary Ellen said, putting her hands on her hips, "let's get 
some ground rules established.  From now on, you don't tell me what to 
do.  Understood?" 
 Aunt Jennifer sniffled tearfully, and nodded her head.  She kept her 
eyes down, as though she was afraid to look Mary Ellen in the face. 
 "Secondly, I want my own bedroom.  I want to do a little entertaining, 
and I don't pipsqueak here to bother me." 
 "But…"  Aunt Jennifer's protest was cut short by Mary Ellen's hand 
across her mouth.  It was a hard blow, and almost knocked Aunt Jennifer 
off her chair.  She put a hand to her mouth, and then nodded vigorously. 
 "Okay," she almost screamed.  "Just don't hit me again." 
 "I won't if you behave," Mary Ellen said.  "And that means you do 
whatever I say.  Is that understood?" 
 "Yes." 
 Mary Ellen smiled smugly, and then turned to me.  "What do you think, 
pipsqueak?" 
 I didn't know what to say.  This sudden turn of events was almost too 
much to comprehend.  I'd always been slightly afraid of my Uncle Mickey 
and Aunt Jennifer.  To see my former authority figure cringing, naked, 
in front of my big sister boggled my mind.  It was a little 
disconcerting, but it was exhilarating as well.  If I read the look in 
Mary Ellen's eyes correctly, I was no longer low man on the totem pole.  
That curse had been passed over to Aunt Jennifer.  I didn't want to do 
anything to jeopardize the sudden promotion. 
 "I think you should do whatever you want," I said.  Aunt Jennifer shot 
me a hate-filled glance, but I didn't care.  I was riding Mary Ellen's 
coattails, and nothing Aunt Jennifer did could scare me. 
 "I'm going to teach you a little respect for me," Mary Ellen said.  
"Uncle Mickey's got some rope in the basement, pipsqueak.  Go get it." 
 The rope was thin white cotton with a rough texture to it.  There must 
have been thirty or forty feet of it.  I didn't know what Mary Ellen had 
planned, but I wanted to see what it was.  I couldn't believe how 
excited I was by all this.  I slipped my hand down my pants, and felt my 
pussy.  It was wet, and I wondered how I'd managed to pee my pants 
without knowing it.  At the tender age of thirteen, I didn't yet know 
about things like pussy juice, and sexual excitement. When I returned, 
Mary Ellen had taken Aunt Jennifer into the parlor.  Aunt Jennifer was 
laying face-down on the floor, with Mary Ellen standing over her.  Mary 
Ellen took the rope from me, and then got to work hog-tying Aunt 
Jennifer.  It was a clumsy job, but when she was finished, Aunt Jennifer 
was trussed like a pig ready for slaughter.  Her legs were bowed, and 
her ankles and wrists were tied together.  Mary Ellen had looped rope 
around Aunt Jennifer's neck, and I could see that it was cutting into 
her throat, and making it difficult for her to breathe. 
 "You better be careful, Mary Ellen," I said.  "She might choke to 
death." 
 "Not a chance," Mary Ellen laughed.  "She'll choke, all right, but I'll 
be here to see that she lives.  I'm going to have a lot of fun with our 
dear Aunt Jennifer." 
 Mary Ellen sat on the floor in front of Aunt Jennifer, with her legs 
spread wide.  With one hand, she slowly separated the folds of her pussy 
until her pink, gaping interior was completely exposed to view.  Her 
nipples and clitoris were both hard.  The interior of Mary Ellen's pussy 
was pink and moist, and the white, creamy juice was thick along the 
walls of it. 
 "Look at me," she said. Aunt Jennifer had been laying on the floor with 
her eyes closed.  Her lips were parted so she could breathe through her 
mouth, and I could see the pink tip of her tongue pressed against the 
roof of her mouth.  At Mary Ellen's command, her eyelids flew open.  She 
was looking directly into Mary Ellen's cunt. 
 "I want you to lick me until I come," Mary Ellen said.  "I've always 
fantasized about having you eat my pussy, and now you're going to do 
it." 
 Carefully, Mary Ellen edged forward until her pussy lips were a 
fraction of an inch away from Aunt Jennifer's mouth.  She smiled 
cruelly, reached out, and pinched Aunt Jennifer's cheek between thumb 
and forefinger. 
 "If you eat my pussy good, I might let pipsqueak eat your pussy.  You'd 
like that, wouldn't you?" 
 Aunt Jennifer said nothing.  Mary Ellen slapped her face hard enough to 
bring tears to Aunt Jennifer's eyes. 
 "Answer me when I talk to you," she screamed. 
 "Yes," Aunt Jennifer said tonelessly.  "I'd like it." 
 "You'd like what?"  Mary Ellen's hand was poised to strike again if 
Aunt Jennifer gave the wrong reply. 
 "I'd like it if Leslie ate my pussy," she said, and as she said that, a 
solitary tear rolled down her face.  For a second, I felt sorry for her.  
I thought about trying to help her, but the thought of Mary Ellen 
administering a beating to me quickly dissuaded me.  I knew how hard 
Mary Ellen could hit, and how cruel she could be. It was hard for Aunt 
Jennifer to eat Mary Ellen's pussy.  She'd never eaten another woman's 
pussy before, and she had to be coached in how to lick and suck the 
folds of Mary Ellen's pussy.  Mary Ellen was a hands-on, vocal teacher.  
She held Aunt Jennifer's ears, and moved her head this way and that, 
trying to get Aunt Jennifer to lick her most sensitive areas.  Aunt 
Jennifer tried to obey, but the angle was wrong, and the rope around her 
neck kept cutting off her circulation so that she had to stop every so 
often to catch her breath.  It was becoming frustrating to them both.  
Finally, at Mary Ellen's urging, I helped by holding Aunt Jennifer's 
head up at the proper angle, but even so, it was tough going.  By the 
time Mary Ellen had had her orgasm, Aunt Jennifer was a sopping mess.  
There wasn't a dry spot of her body, and the floor was slick with water. 
Mary Ellen didn't force to me eat Aunt Jennifer's pussy, and I was 
grateful for that.  I didn't know what to do, and I didn't want Mary 
Ellen getting angry at me.  Instead, Mary Ellen allowed Aunt Jennifer to 
go upstairs to her bedroom for a shower and a change of clothes.  Mary 
Ellen had no doubt that she'd completely broken Aunt Jennifer's spirit. 
Uncle Mickey called about an hour before dinner time to say that he was 
going to Hurley's bar for a drink, and would be late getting home.  We 
all knew what that meant.  He'd drink until he passed out, and would end 
up spending the night on the cot in Hurley's back room.  Mary Ellen took 
the call.  Aunt Jennifer didn't like that news, but it suited Mary Ellen 
just fine.  She was still feeling feisty from her earlier victory.  She 
replaced the receiver, and laughed deep in her throat.  She hadn't 
bothered dressing after taking her shower, and wore only a torn T-shirt 
and a skimpy pair of panties that barely covered her ass. 
 "Come on, Aunt Jennifer," she said.  "Let's play a game." 
 Aunt Jennifer was skittish.  She tried to pull away from Mary Ellen, 
but my sister held tightly to my aunt's arm, and forcibly dragged her 
into the parlor, site of her former humiliation.  Aunt Jennifer wore a 
one-piece red housedress and a pair of flat-heeled shoes.  A headband 
held her hair away from her face.  She was trembling in anticipation of 
being beaten.  Mary Ellen had physically whipped her, and thoroughly 
humiliated her, and Aunt Jennifer was clearly afraid. 
 "I've been thinking about that ass of yours," Mary Ellen said.  "It's 
the only part of you that's worth a damn.  Your tits are smaller than 
pipsqueak's over there, and God only knows when the last time you used 
your cunt.  But that ass…"  Mary Ellen clucked her tongue approvingly.  
"That is choice." 
 She grabbed a handful of Aunt Jennifer's buttocks through the material 
of her dress.  Aunt Jennifer shuddered, but did not otherwise move. 
 "You're not wearing underwear," Mary Ellen said, in mock surprise. 
 "You told me not to put any on," Aunt Jennifer said.  She was beginning 
to cry again, and once more, my heart went out to her.  It wasn't that 
she was a bad person.  It was just that she wasn't Mom.  I didn't hate 
her in the way Mary Ellen did, but I didn't feel any real affection for 
her, either. 
 "Take off your dress."  To me, Mary Ellen said, "Get me the candles." 
 I found the candles in the cabinet near the pantry.  They were long, 
beeswax candles in a variety of different colors.  There were more than 
a dozen.  I grabbed them all, and took them back to Mary Ellen.  By this 
time, Aunt Jennifer was naked except for her shoes.  Her eyes were 
downcast, and she was trembling again.  To her credit, she didn't try to 
cover her breasts or pussy.  She stood with her hands at her sides, 
waiting for Mary Ellen's orders. 
 "Look at me," Mary Ellen said.  She removed her T-shirt.  Her breasts 
popped into view, the nipples hardening.  She cupped them in her hands, 
her fingers pulling at the nipples.  "I've got beautiful tits, don't I?" 
 "They're very big," Aunt Jennifer said softly. 
 What surprised me was the look in Aunt Jennifer's eyes.  I expected to 
see fear and loathing.  I wasn't expecting a gleam of lust.  Her eyes 
were fixed on Mary Ellen's chest, on her hands cupping and rubbing her 
breasts, on her fingers pinching and pulling at her nipples.  The tip of 
her tongue appeared, and slowly traveled over her parted lips. 
 "Touch me," Mary Ellen said, moving close to Aunt Jennifer. 
 Slowly, hesitantly, Aunt Jennifer reached out and placed her hands on 
Mary Ellen's boobs.  Her hands were small, and barely covered the tanned 
mounds. 
 "Touch me," Mary Ellen said, more insistently.  It was obvious what she 
wanted. 
 Aunt Jennifer began to massage Mary Ellen's tits.  Her hands moved in 
slow circles, kneading and touching the flesh.  
 Her fingers plucked at the hardened nipples, stretching them to their 
maximum length. 
 "Suck them," Mary Ellen said.  She wasn't looking at Aunt Jennifer 
anymore, but was looking directly at me.  There was a knowing smile on 
her face.  She'd seen my look of rapt attention, and knew that I was 
becoming hooked on the sexual display in front of me. 
 Aunt Jennifer obediently bent her head, and took Mary Ellen's breast 
into her mouth.  She sucked the nipple like a child with a bottle, her 
cheeks hollowing as her lips worked at the nipple.  There was a look of 
intense concentration on her face, almost as though she was committing 
every second to memory.  Her tongue licked at the areola, and then her 
teeth captured Mary Ellen's nipple, and bit down.  A hiss of pleasure 
escaped Mary Ellen's lips. 
 "Oh, yes, you bitch.  Bite me." 
 At night, in our joint bedroom, Mary Ellen would masturbate when she 
thought I was asleep.  The sounds she was making now were the same 
sounds she made in her bed when her climax was imminent.  It was obvious 
she was extremely turned on by having Aunt Jennifer service her 
sexually. 
 Aunt Jennifer moved her mouth to Mary Ellen's other breast.  Without 
being told, her hands slid down Mary Ellen's body, and under the band of 
her thong-style panties.  Her fingers moved beneath the material, trying 
to find Mary Ellen's engorged clitoris.  When she found it, she pinched 
it between thumb and forefinger, rolling it back and forth like a slick 
and slippery marble.  Mary Ellen began babbling. 
 "Oh, you bitch.  You whore.  Bite me.  Bite me.  Bite me.  Stick your 
fingers up my ass.  Fuck." 
 Obediently, Aunt Jennifer moved her hand to Mary Ellen's buttocks.  She 
parted the heavy cheeks, and slid her middle finger into Mary Ellen's 
receptive asshole.  Mary Ellen exploded in an orgasm. 
 I watched the two of them clinging together, Mary Ellen's body shaking 
and trembling from the waves of pleasure that were washing over her.  
Aunt Jennifer hadn't released her lip lock on Mary Ellen's breast.  Her 
teeth were cutting deep into Mary Ellen's nipple, but surprisingly, Mary 
Ellen seemed to like the sensation.  I'd never seen either one of them 
like this before, and I wondered who was really the dominant player in 
this strange and twisted relationship. Staggering and falling, Mary 
Ellen and Aunt Jennifer collapsed together on the sofa.  They embraced 
each other tightly, and kissed passionately.  It was an open-mouthed 
kiss, and I could see their tongues intertwine as their hands caressed 
each other's bodies.  I didn't know whether to stay or leave.  I chose 
to stay, remembering that Mary Ellen had threatened to kick my ass if I 
left. 
 After a while, the two women pulled apart.  Mary Ellen skinned her 
panties down her legs, and tossed them aside.  She spread her legs, and 
used her hands to rub her pussy lips.  There was a contented look on her 
face. 
 "God, that was good," she crooned. 
 "Yes, it was," Aunt Jennifer said, "but I haven't come yet." 
 "Pipsqueak," Mary Ellen said, "get over here." 
 I walked over.  I still held the candles in my hand.  The look on my 
face must have been amusing, because both Mary Ellen and Aunt Jennifer 
laughed at my expression. 
 "I think she's scandalized," Aunt Jennifer said. 
 "Well, we'll just have to remedy that, won't we?  Get your clothes off, 
pipsqueak.  It's time you got an education."
