Despite the shells we were all wrapped in it only took a half a day before Dad sat down next to me on the porch steps, wrapped an arm around me, tilte... his head to look me in the eyes and ask straight out."Something happen during your trip, Davey? Something you don't want to share with your parents?"I sighed then, with a deep, slow release. Had I been holding that in the entire time?"Yes and no, Dad. Yes and no," I said, shaking my head. "Something I don't know how to share. Don't even know if. 'Your hand feels nice on my cock, so smooth and delicate, tiny white hand on my big thick cock looks sweet!'I look at his face for the first time since he whipped his cock out and make eye contact with him. I feel he is daring me, words unspoken but a current of anticipation in the air. 'I am sorry I can't do this I have a husband and this is not right!''From what you say about your husband I think he would encourage you to do this!'I hesitate again unsure, wishing Neil was here encouraging me,. I wanted to fuck her ass, if it felt that good with my finger I needed to see how good my dick would feel sliding into her tight asshole. Fingering her was such a turn on that I couldn’t resist. Karyn told me that she loves getting ass fucked but only lets Brad do it to her and they role play using a strap-on dildo and she returns the favor which she didn’t really like but needed to keep him happy in their relationship.She guided my cock between her ass cheeks and I put some spit on the head. Ok she doesn’t have a real choice here. I don’t have any control over the fact she is getting a big load of swimmers. Her mom will the next time I fuck her too. At least this time I was willing to make sure it would happen.When I let us cum together, my head was against her cervix. I kept blasting sperm into her uterus until it looked full. Her egg would get fertilized before we started the shower, but she had me fuck her in the shower just to be sure.Sorry Emily, no sperm for you this time..
