You need to know, I work for Marla, too." Why are you a client then?" Sandra didn't sound disappointed at the loss of a tip. Just curious why I was a ...lient paying for sex if I was a call girl."Marla has a party scheduled for tomorrow and..." A bachelor party," she asked and I nodded. Sandra laughed, "I'm one of the girls Marla is sending! Are you...?"I nodded and laughed, too. "The thing is, I wasn't lying about never having been with a woman so Marla sent me you to, ahh, break me in." Well,. . oh Jesus, RJ, . . . . I’m gonna cum so quick baby . . . . fuck, you make me so hot big brother . . .”RJ continued finger-fucking his sister through the leg-hole of her panties, Each time his fingers thrust, more girl-goo would ooze out making Kayla’s panties sodden. Kayla’s cries and moans were stifled only in that RJ had his mouth glued to hers and was busy plunging her mouth with his tongue. Each time RJ thrust his fingers in, Kayla would buck wildly on his hand.Suddenly Kayla pushed. Without any warning, I started back up, giving her six good swats on her bare ass. Heather screeched as the sting hit her and she struggled on my lap.But she was no match for me. I had her arm behind her back, her legs flailing helplessly against the sofa, and her ass presented to me perfectly.Then I threw in something she hadn't anticipated. After the six swats, I rubbed her flaming ass, letting my fingers "accidentally" trail down between her legs.I rubbed her pussy as I caressed her ass and. She said to not let go of them until I was done.I held on for a couple of more strokes before I blew and shot another massive load this time directly into her uterus. I squeezed her nipples as I started to cum and it set her off as well. With each of her contractions the top of her uterus hit the head of my dick. It was ultra sensitive because I happen to be cumming at the same time which made me cum more. All thoughts and muscle control were gone. We were stuck in a loop. One of us would.
