Her arms were shafts of searing agony and her tits and arsehole were likewise on fire. She was also sweating. Jenny wiped Brandy’s face and br...asts with a towel, being sure to touch off the clamps by moving them about vigorously. Brandy moaned in response. A big tear rolled down her face. ?Let’s talk about the real reason you are here,? said Jenny. ?For a while now you’ve known we’re not sisters at least by blood. You were adopted. It makes no never mind to me. Also I know you are in. " I was at a loss for words. "It's okay Daddy, I'm just glad you weren't my actual Daddy!" She giggled. I immediately relaxed. "I'm sorry Chloe, I didn't mean to spy on you.. I heard what was going on, and when I saw what you were doing, it was just so incredibly hot, I couldn't turn away. I've wanted you since you were so young, thinking it would never happen... and here we are." I said smiling. "I've wanted it a long time too Daddy.. more than you know..." Our eyes met, both full of lust.. He seem to make up his mind in the blink of and eye as hebegan removing his clothes,threw them aside and reach out for Mark as hesaid."Come here you little bitch."Mark melted into the mans arms,he could actually feel the FRanks abspressing against his belly,the big biceps crushing his shoulders and back asthe mans lips pressed against his own,then his big tongue began r****g hismouth.Mark sucked the tongue as though it were a cock,chills running up hisback.He could feel Frank's cock against his. "Ooh! it's very warm and thick!" she said playfully "Does it get bigger?" Yes" replied Thomas excitedly.Christy then began jerking it some more and we watched Thomas cock getting bigger and longer in her hand, before Christy then grinned, and then opened her mouth and engulfed Thomas's hard cock."Fuck!" I heard Mark exclaim as we watched our best friend getting his dick sucked by another one of our best friends.Eagerly for the next minute or so, Christy jerked Thomas thick shaft while sucking.
