Dude, you weren’t lying. This pussy is hella tight,” Mark said as he slowly built his rhythm. Mark placed a few firm smacks on either side of my ...ister’s ass. Then he gripped my sister's makeshift shirt handle and began to fuck her hard enough that the smacking sound of his hips against her ass where now as loud as Cody’s was before him. Cody was now leaning down to fondle my sister’s tits. She was moaning so loudly, it made me nervous. I think Cody felt the same way, because he quickly sat. She started to stroke me quite aggressively. I was, to use a pun, a touch shocked that this was happening. We hadn’t talked about something like this she was just doing it. I mean, you hear stories about blowjob and shit, but I always thought they were bullshit. This woman was not messing around though, she had her hand on my cock stroking away at rapid pace. She stopped for only for a moment, quickly taking her top off and asking if I liked that better. I nodded a yes as she bent over grabbing. She started pulling out and pushing in a lot faster and it felt so good. I started pushing back to meet her hard thrusts. I was in such ectacy I didn't even know what was going on. She said, "Oh YES, Oh YES! Your ass is so tight and hot! I don't think I'll last much longer." And within seconds she screamed at the top of her lungs, "OH I'M CUMMMIINNNNNGGGG!!!" Just as she said that I felt her hot cum pour into my asshole. It never seemed to end. I looked down and I realized that I had cum too,. As ever when given a present she was very gushing in her thanks. She wasn't quite so thankful once I'd laced her into the unforgiving steel stayed corset.The pinky ruffled satin panels looked fantastic but I hadn't expected the waspish waist they enforced or the way that they boosted her boost and flared her hips. With the corset tightly laced her body screamed femininity. She looked so sweet in the pink satin heart shaped panties she'd bought with her pocket money they went beautifully with.
