Mark was worn out, having cum 3 times or so today, but was enjoying Jims cock against his inside my arse, Jim also wasn’t sure if he was going to be...able to cum again, but I just kept orgasming, as they tried hard to succeed. I heard Grant say some thing to Mark, and then quickly felt Marks cock push harder still into my womb, Jim seemed to jump to, as they now fucked me harder, it wasn’t long before both guys started to swell and loose control, I could feel my arse being ripped open by their. There was one other person there…one of the waitresses who walked around taking orders from spectators. All the employees were allowed to use the gym, though the wrestlers and the strippers who worked in the bar that shared our building were usually the only ones who did. I felt better as I went through my stretching routine. The rote movements allowed me time to think. I was learning more about my abilities but nothing useful yet. I realized my self-confidence might be lacking a bit and that. It was such a turn on watching my girlfriend being violated like this, her ring stretching around this stranger’s member. He was easing it in slowly while I pulled her cheeks wider and wider until eventually he was inside her to the hilt. She arched her back and gasped.Meanwhile his two friends had moved to Serena’s side and were tugging at their cocks’. The shortest of the three, amazingly, had a massive member and he was stroking it slowly just above Serena’s head, the other guy was pawing at. "It's just so fucking beautiful."Mum gripped my buttocks and heaved herself back at me."Do it, Tommy, do it to me, fuck my fucking brains out."Her nails dug into me, into the skin of my bottom and then further up, she raked my back, making me gasp with the pain of it, it was exquisite. I growled and powered harder and deeper, feeling my spunk beginning to rise."I'm cumming Tommy, fucking hell, I'm cumming."In the chair beside us, Jill had both legs in the air, a whole fist in her cunt and two.
