I got up slowly, a little hungover, although I didn't know what it was called then, not too great anyway. My tits were still hanging over my top so I...tucked them back in and looked around for my shorts which I finally found but I never did find my panties. At least I had clothes and could get home without being arrested. I was quite sure my mom was still asleep. So, I got up slowly and felt the cum really start dripping out of my cunt but there was nothing I could do about it so I started. Erika decided, therefore, there and then, that she would full-on join in the threesome sexting and wait for what developed. She would not raise what bothered her with Christine face-to-face. In the quick exchange of words, things are often wrongly said, and answers too promptly given. The shared sexting would bring between her and Ben and Christine, Erika hoped, a step-by-step emerging arrangement. But with Ben she would need to resolve what was going to happen between them once they engaged in. “Fuck me, big brother,” she said smiling and getting up on her bed.“As you wish,” I said aiming my granite hard erection at the best tasting pussy I knew. I filled her pussy with it in a single stroke, generating the first sound she had made since we walked in her room.“Ohh, Michael ... you are the best and biggest I have ever had,” she said.“I’m about to cum any moment. May I please cum inside my little sister?” I pleaded.“No, you have to wait. I need my pussy to be nice and slick before you. I met up with Suzy before the last class of the day; we were in the same sociology class. She asked to go over my dorm later; I tried to suggest her place and told her I had a roommate. She still wanted to come over to hang out, have dinner, then have some fun.When we arrived, Cal was there and was dressed in light lounge pants and a t shirt. His bulge was so pronounced that you couldn't help but notice it. Suzy noticed it too and stared for a minute; she seemed a bit flirty too.We left Cal.
