It was slightly above average for a normal male but he is very small (maybe 5’5”) so I was happy to see that I had something to play with.Once he ...ad everything off and was fully exposed he straddled me and then put his foot up on the rail and pushed his cock towards my face. I gladly accepted the advance and took his cock into my mouth. He scooted into a better position so that he could fully get his cock in my mouth. Within no time I was just holding my head still and he was pumping his cock. His seventh period distraction had, as usual, left him with an urgent need to break out his stack of old Playboy magazines and play with himself. He opened his closet door, pulled his small desk chair to it, and climbed atop it to reach into the deep recesses of his closet shelf. He felt the comforting weight of the six or seven heavy magazines in his grasp when he was nearly startled right off of his perch."Hey Sport! Whatcha doin'?"He regained his balance, quickly stepped down from the chair,. I Didn,t realise Tina had already arrived as I was running a bit late and as I dashed into the master bedroom naked from the waist down there she was with Sarah showing her some new clothes she,d bought for our k**s. I turned bright red as she got a full frontal view of my cock that stiffened instantly. “Excuse you, but where,s your underpants?” Sarah asked amused at my discomfort. “ Sorry I forgot them and Didn,t realise Tina was here already!” I ducked back into the bathroom till my wife. ” She looked down to where my erection was touching the waistband of her panties. “Uh, does that hurt?”“No, it’s just pressing against my underwear, and that part isn’t comfortable.” I noticed her nipples were standing out from her breasts, and the sight only increased the pressure in my pants.“Can I see it?”“Sure,” I reached down, and her hands caught mine.“May I?”“Yes.” My heart was pounding, and I flinched a little as Sharon slipped her fingers into my waistband.She pulled the garment.
