“DON’T STOP FUCKING MMMEEE OUT SSSHHIITTT I’M CCCCUMMMIINNNGG!!!” Kalley thrust her hips up savagely and her head side to side as she climaxed... Her tight little pussy clenched my dick so hard that I blew my load deep into my sister. Out of breath I rolled off of her and she leaned over and started kissing me while she jerked me hard again. “I am going to ride you until you cum.” Kalley told me and I smiled as she lowered herself onto my dick. This was without a doubt the best sex I had ever. I do not know if your child would have the vestigial organ or not. I would presume so, but I do not know which DNA marker actually programs it. As for protein absorption, this is something that will require further study. I do not have the necessary information to form a theory at this time.”“So, you need one of us to fuck Cal, while the other one only sucks him off? Sorry, not going to happen that way, Mike,” Eve said. Dora nodded.Beth looked at her watch. “As fascinating as this is, and it is. It's just..." She looked up at me shyly. "I haven't done anything -- I mean, not much." She hesitated, then smiled. "So ... will you show me how to, to be sexy?"I grinned, but only inwardly. I had her in the palm of my hand now..."Hmmm," I said thoughtfully. "Well, I'll try, I guess." I gazed at her, tapping my teeth with my fingernail like I was thinking about what I might to teach her first. Of course, I knew exactly what I wanted. "Let's see. Do you know how to kiss?" Well ... kinda."I. Then Mary asked who I was dating. At that time, I wasn’t dating anyone, but since I had heard of the divorce, I was thinking of tapping Mary’s sweet little ass! I told her I wasn’t dating anyone, and I asked her if I should ask her sister out. I asked more to get a reaction than anything else.Mary’s sister was her opposite. Mary was short; her sister Carrie was tall at 5’-8”. Mary was small-chested and her sister had a rack any woman would be proud of! Carrie also sported a low slung.
