Mothers slave 2 vivire@mail.com A story of mother and son with a passion for pumping iron. After last night events all I were able to think about was of Johnny. After pumping some iron in the gym I went shopping for some supplements for Johnny seeing as he wants to bulk up. I got the usual muscle building protein as well as pre and post workout supplements. Personally I never use supplements except for whey protein before and after my workouts, but I think Johnny needs a little more help than me. I also got a new bikini, a naughty black number. Johnny came home a little later than usual, at first I was afraid that he felt awkward about last night's activities. Hi mum guess what, I bench pressed 175 lbs today 5 pounds more than two days ago exclaimed a very excited Johnny. That's fantastic Jonny. Well it's still far short of your 260 lbs mum. Don't worry about that Johnny, I got you some help I bought you some supplements, let me quickly fetch your dinner and after that mummy will make you a nice protein shake. But first you should drink this post workout juice I've brought you. Thanks mum, this stuff taste awful I hope it works. After Johnny finished his dinner I ask him to get dressed in his speado. When I returned to the lounged he was already there and he removed the furniture to the dining room. I was wearing my new black number for him. Johnny why did you move the furniture? Well mum you said that we will be wrestling tonight remember. I guess I did, what do you think of my new bikini? It's fantastic mum, you should really think about competing in bodybuilding tournaments. The definition on your tummy is fantastic. I never thought of competing before maybe I should shouldn't I? At this point I made some posses, I could see that Johnny already has an erection. As I made a bicep pose I started to lick my 16'' bicep this made Johnny grasped. Johnny let's play I said, hit me as hard as you can in my tummy. Are you sure mum? Yes dear. Thump. No Johnny you must try to hit harder. Okay mum here goes. THUMP! Did it hurt mum? No I barely felt it try again hit me a couple of times. Okay here goes strike three said Johnny. THUMP TUMP THUMP!!! Okay I felt those three hits but it didn't hurt at all. Yeah mum I could feel that your abs are like super tight. Now it's my turn mum hit me the hardest that you can. Okay dear here comes mummy. THUMP!!! I really hit Johnny as hard as I can in his abs, so hard that he knelt over on his knees. Oh I am so sorry Johnny. No need t be mum this is just a game. Secretly I enjoyed hitting Johnny, It was such a turn on. As he got up on his feet I didn't waste any time I grabbed him and hit him in the abs a second time. This time he turned white and slide to the floor. As he tried to get up I pinned him down with the pressure of my foot on this chest. Johnny this wresting match is over. Mum we just started. I win by default and the night is still young. Johnny please take your speado off and I will take my bikini off. Okay mum. I started to flex again and to lick my bicep I can see that Johnny is now fully erected. I am such an awful person, but hey at least I make my son very happy. Johnny come feel how hard my muscles are. Mum they are rock solid. Let's play a game Johnny, I want to see you came. As I said this I do a front bicep pose. After about 8 minutes of flexing my muscles Jonny started to cum and squirt onto my thick muscular right thigh. Oh Johnny I said as I draw my index finger over the cum spot and binging my hand close to my mouth I start to like it. Johnny still hard stairs at me, do mummy a favour and lick me clean Johnny. Yes mum, he bends down and starts to lick me once he finished he moves to my vagina and starts to lick my pussy, I could by now not resist anymore and push my son to the floor. That night we had sex 3 times and twice he complained that I hurt him too much by squishing too hard. Poor Johnny he will have to toughen up to be keep up with me.
