Oh shit, oh shit, oh shit, I kept saying to myself. My heart was beating at a million miles per hour and I began to feel sick, embarrassed, and excite... all at once. We had just come from the pool, so I still had my one piece on as I walked up to Sis, who was already soaping up with her back to me. Feeling very uncomfortable about stripping, I quickly undressed and took the shower next to hers. She was clearly shocked to see me standing there. “My shower is broken, so I had no choice but to -. I can’t believe that’s all you’re going to say, though.”“Don’t worry, it’s not. Those are a couple of glorious hunks of manhood she’s got there. In case either of them ever wants someone to play with those beautiful sacks of marbles, be sure she gives them my number, would you? My, my, what cute asses and handsome balls on those boys!”I shook my head. “And you wonder why I’m so reluctant to share things with you. Hey, answer a question for me; do you find this shot extremely erotic, or is it. Mark must have swallowed two-thirds of Mikes cock when he would wrap his lips around Mikes cockshaft and bob his head up and down. Mark stopped stroking his own cock and used his hand to hold and fondle Mikes balls. I liked it when I saw Mark suck each of Mikes nuts into his mouth. Mike must have liked it too, because he was standing there with his eyes closed and with a smile on his face. I was tweaking a nipple with one hand and running my fingers up and down my pussy slit when I heard Mike. I could only get 1/2 of his huge cock in my mouth but I tried really really hard to Choke on it. As I was throating his cock I kept hitting the popppers anyway wondering if he was going to split my ass wide open with this massive cock. After about 15 minutes of sucking ( my jaw is till sore lol) I came up for air and more popppers. Well, he decided to bend me over and without hardly any lube he rammed his massive meat inside my ass !! I gasped and felt like he was r****g me ! I was helpless.
