I fetched Tony a condom and he asked if I had any extra lubricant. I offered him the KY jelly, but he pointed to Judith's baby oil, saying, "That's t...e best stuff." Tony got Judith to rub some all over his cock then she fitted the condom onto him and he got her to squirt some more oil over the condom. Finally, he asked me to rub some into Judith's cunt, which I did. At that time, neither Judith nor I knew what effect oil has on condoms, although Tony did. So, let this be a warning: it. Suddenly, Brit squealed in ecstasy, her body tensing up and shuddering. For a moment he thought she was going to bite down on his dick. He knew how painful that could be. But she kept her mouth open through the climax, to his relief.Jeff was the next to cum. The sounds of his little sister in the throes of passion were enough to push him over the edge. His own body tensed up, straining against the ropes that held him bound. He found the check on his motion to be ironically liberating. He could. Yeah!" I replied not sure what else to say."Oh its going to be a good one this time!" he then grinned, before he began fondling his hanging member excitedly."You better hurry up! You don't want to be last! Unless your into that kind of thing?" he then said, before he strolled off through another door across the changing room.So, still unsure what was actually going on, and what I had walked into, I got undress, put my things into a locker, and then nervously followed everyone else into the next. She screamed and bucked and the combination of her screams, her bucking ass and her tight asshole caressing my cock were electric. The feeling of power went straight to my balls. I plunged in and out. I pulled back, leaving only an inch inserted then rammed home again. Again she screamed. I kept it up, pounding my huge member in and out of her asshole while she screamed with pain.Finally I decided to come. I crushed her tits as hard as I could twisting them to maximize her pain and my pleasure..
