Visiting by Will Travis     I had just returned from my junior year of college. I was the first time I had been home since I started college.  My parents were deceased and my step-sister and I had been raised by different family members.  We stayed in touch by email but we had allowed three years to slip by without seeing each other.  She is two years younger than me and had just finished her freshman year of college.  She and four friends were renting a house.  It was a big house and it had a pool in the backyard.  My step-sister said there was room for me to stay so I decided to go visit for a week.   It was funny to see her grown.  When I last saw her, puberty had barely started.  She was now a very curvy woman.  The girls she shared the house with were all pretty stacked.  When I arrived all the girls were in the backyard around the pool.  My sister introduced me to her roommates.  I went inside and changed into my swimsuit.    My step-sister Karen was grilling some burgers.  Her roommates Cindy and Beth were laying face-down on lounges working on their tans.  The third roommate Janet was swimming laps in the pool.  She was on the college swim team going through school on a partial scholarship.  I was enjoying myself hanging out with the girls.  Initially I did not talk much with Janet since she was knocking out laps in the pool like a machine.  Cindy and Beth were both petite, fit looking with suspiciously large firm boobs.  They looked great but almost too perfect for their petite bodies.  My step-sister had a fuller figure and her large chest looked very proportionate to her build.    The three of us were sitting around talking when my Karen started serving food. "Janet, time to eat." My sister called toward the pool.    Janet called back, "Ten more laps.  Save some for me."   Cindy looked at me and rolled her eyeballs toward the pool.  "Janet is a little obsessed about her workouts.  She is always in the pool or lifting weights."   We were all eating when Janet finished her laps and approached the ladder at the end of the pool closest to us.  As she emerged from the water my jaw dropped.  She had huge shoulders, and large arms with bulging biceps and triceps. Her tits were large and firm.  As she climbed up the ladder I could see an incredible set of washboard abs.  I was really amazed when her legs came out of the water.  Her thighs were amazingly muscular and nearly as big around as her waist.  It then became apparent that she was at least six foot.  This made her three inches taller than me.  I could not help but stare at this amazing woman as she toweled off.  This was a big girl.  It occurred to me that it would take a lot of muscle to move a big body like hers through the water quickly.  Janet caught me staring.  She smiled and winked at me and walked over to the grill to get her food.  As she stood in front of the grill dishing up three hamburgers, I got to see her ass.  It was as solid and shapely as the rest of her.  She turned around to walk toward us and caught me staring again.   As she approached our table, it occurred to me that there were no more chairs available.  I started to stand to give Janet my chair.  She put her hand on my shoulder and pushed me back into the chair.  She looked straight into my eyes and said, "We can share."  She then sat sideways in my lap.  Her legs were hanging off my right thigh and her butt was on my left thigh.  Her right upper arm was pressed up against my shoulder.  Her tits were right in front of my face.  I was quite happy to have her in my lap but acting nonchalant reaching around that massive chest was a bit awkward.   We all sat and talked, discussing school and eventual career plans.  Once the food was gone we were sitting sipping beers.  Janet shifted her weight so that her but was rights over my crotch.  She also had her right arm over my left shoulder and behind my neck.  Her right breast was pressed against my chest right below my chin.  I could not help but get a hard on.  I know Janet felt it and she very subtly adjusted her weight in my lap to keep the pressure on my cock.    I wanted to volunteer to help clear the food but I did not want to stand up with a bonner sticking out the bottom of my trunks.  Karen, Cindy, and Beth cleared the dishes and took everything inside.  Janet was still in my lap, sipping a beer and acting as if nothing was amiss.  "Maybe we should go inside and help."  I said.   "Go ahead and try." Janet whispered into my ear.  I tried to stand but Janet was holding the back of my chair with her right hand and she had her ankles locked around the chair leg.  I could not budge her.  "It looks like you are my prisoner."  she giggled.   "Looks that way,"  I said as I ran my right hand over her massive thigh.    Janet grabbed the back of my head with her left hand and pushed my face down to her breasts.  I began to kiss them.  "What about the girls?" I asked.   "They know to leave us alone." Janet said as she pulled her bikini top aside so I could kiss her nipple.  I reached down with my right hand and started to rub her clit through her bikini bottoms.  She spread her legs and allowed me access.  We sat their a while with me sucking on her nipples and fingering her clit.  Janet shifted her position in my lap so that her back was toward me and her thighs were straddling my lap.  She spread her legs so that she could reach down and play with the tip of my cock which was sticking out the bottom of my shorts.  I pushed aside her bikini bottoms and continued to tease her clit while and played with her left nipple with my other hand.  I could not help but notice how amazingly broad her back was as I kissed it.  Janet was driving me nuts with the attention she was giving my cock.  I wanted to fuck this lady bad but every time I tried to stand she thumped my back into the chair with her ass.  She was clearly toying with me and it was obvious that she was strong enough to do whatever she wanted.    Janet then stood up and pushed backward with her ass against my chest and my chair and I flipped over backward.  Janet landed on top of me sitting on my chest.  She quickly pinned my arms under her thighs, reached down and pushed my swimsuit down around my thighs.  She grabbed my cock and started stroking away.  I struggled to get my arms free.  She shifted her thighs so that they were on either side of me and then squeezed her powerful legs together so that she had my arms pinned to my side.  The more I struggled, the tighter she squeezed her legs until I  could barely breathe.  All the while she was stroking my cock up and down.   Then she bent over and began to toy with the head of my cock with her tongue.  I was helpless laying there on my back in the grass.  MY arms were pinned to my side while her prodigious weight was parked on my chest.  She was teasing my cock with her mouth and hands. I was helpless and enjoying every minute of it.  Janet then released my arms and scooted toward my cock so she could wrap her tits around my cock.  She spread her legs out so that I could not roll or move her.  At least now I could caress her muscular thighs and butt.      Janet had me on the verge of coming and knew it.  Janet untied the stings on her bikini bottom and threw it aside.  She then slid down and took my into her wet pussy.  She was fucking away with a hand pressing down on each of my thighs. I reached up and removed the bikini top.  Janet pulled my trunks the rest of the way off.  She then crawled forward and got on all fours.  I crawled up behind her and inserted my cock back in her pussy and fucked her from behind while on my knees.  I fucked away while caressing her broad shoulders and back.  Janet held herself up with one hand and stimulated her clit with the other.  Janet suddenly yelled out in ecstasy as she came.  I came just as she did and I kept pounding away through our orgasms.  We collapsed on the lawn and lay their for a moment.  I was feeling pretty dehydrated and reached toward the table for my beer.  Janet surprised my by wrapping her legs around my waist and pulled me down so that my face was buried in her cleavage.  She wrapped her arms around my neck and squeezed the hell out of my waist with her legs.  "I am not done with you yet."  She pulled my mouth over to her left breast and forced me to suck on it.  As I served her desires she began to grind her crotch against my stomach.  I was getting hard again but she had such a tight grip around my neck that I could not get my cock near her pussy.  After a while, Janet rolled us over onto my back.  She planet both hands on my chest pinning me to the ground.  She mounted my cock and began to pound away.    Looking up at this muscular busty amazon was an amazing sight.  Her big breasts were swaying back and forth as she fucked me.  Her arms, which were as big around as my thighs, held me securely to the ground.  Occasionally Janet would lift one breast up to her mouth and suck on her nipple as she kept me pinned to the grass.  I grabbed the wrist pinning me and tried to move it but even with one arm she had me pinned.  Watching her suck those big tits while riding my cock was too much.  I came again with an intensity I have never experienced.  Janet sat back, released my chest, and began to thrash her clit with one hand as she squeezed and pulled on one tit with the other.  she started to come and was bouncing up and down on my pelvis so hard that I thought she was going to break something.  Eventually, her climax ended and she flipped forward lying on top of me with her chest on top of my face.  We lay there a while resting as I sucked on her nipples.  "I think you should stay in my room for the rest of your visit."   "Do I have a choice?" I asked.    She rose up on her elbows and started swinging her tits back and forth slapping my face with amazing force.  "What do you think?" she giggled.
