I could feel it sliding across the floor as I rode her harder. I wiggled my thumb in her ass, trying to loosen it up. When my thumb moved easily in ...nd out of her, I pulled it out. Sandra shook her head no when I withdrew from her cunt and began rubbing the head of my cock against her ass. I pushed steadily, but nothing happened. Sandra shook her head harder, but I ignored her feeble protest and kept pushing. She was still too tight. I pushed harder and began spanking her sweet ass. The. "Now be a good boy and put your wet lips around it…" She whispered.I opened my mouth as wide as I could and slid my lips over her hard dick. I could taste some pre cum oozing out."That's nice, bitch. You seem to be a good cocksucker…”I sucked in until I had a firm pressure on her entire rod. At this point I only could make the cockhead fit inside of my mouth. She wanted more…“I will shove my dick all the way into your throat, bitch…” She warned.It scared me to even think about. But I could not. Sarah moaning as Sam's cock entered her. They fucked for a few minutes, and broke away from each other after Sam had shot his load.Sarah and Sam both turned and looked at me, saying nothing. "That was really hot," was all I could say.Sarah sat back down on her couch, still naked, with a big satisfied grin on her face. "Play with your pussy for us," said Sam, "Let Philip see."Sarah looked hesitant, pausing and looking at me, and then back to Sam. Suddenly she slid down off the couch and sat on.
