As she stepped inside, she looked around, smiling at the sight of my shoes, purse, new black dress and panties scattered roughly in a line from the fr...ont door to the bedroom. "Either you were very tired when you returned or you brought back someone who was extremely impatient," she laughed."No, I arrived alone but it was quite late and I was tired," I responded."Ah, I see. And how did your meeting with Marianne go?" she asked innocently enough, but I thought I detected a suppressed smile."Just. "You see," he said,"you aren't the only slut." He began to walk around Lisa as if she were a prize he had just won. "Lisa here is a first class nympho." I could swear that I saw her tremble a little. "She will fuck or suck anyone or anything I tell her to. Male or female. Isn't that true, Lisa?" As he said this he roughly pinched one of her hardening nipples.Her eyes were now half lidded and glazed. "Aahhh," she gasped, arching her back to offer her breasts. "Yessss." She said in a breathy. Will your mom be more likely to let you stay if you’re pregnant?”“Oh yeah. Mom wouldn’t want me around her friends with a swollen belly. I’m yours to keep from now on, if you’ll have me. You know last summer if we had started having sex one day, two at the most, earlier we would be working on number two now.”“Wow that almost sounded like a proposal. You didn’t even give me a chance to ask.”“You may have never got around to it. Besides, last summer your mom told me if I ended up pregnant from. .YES!......HARDER!" Bri was yelling and squealing each time Kate bottomed out and then pulled back for another brutal thrust. At first fucking Brianna with the cock had been an awkward experience for Kate, who was unused to a thick heavy tool standing out 6 inches in front of her, but as she banged her sister she became more accustomed to it and thrust harder and faster. The sight of her nubile sister writhing and squealing beneath her was too much for Kate and she could feel her.
