We both new and even Lila told me she assumed that my sister was having sex when she went out on dates, however, I didn't want to hear it or know abou...t. My ignorance in her sex life was my bliss.Let me defend myself here. I was protective but I wasn't fatherly. Diane had her own social life. She would drive out to parties or her girlfriends and go out on dates. The fact being that the more she was away from the apartment, the more fun Lila and I could have.All that was the setup... now comes my. “Good!” My husband said. “Glad you’re having fun. How much farther can you handle?" "As far as you can. How about you, Son?" "Yes, Mom. I want to go as far as possible." "Good," I answered. "The farther we go, the better." “Alright. If that's okay with you, Honey?" "No Problem! Helps me too. I don’t want to stop.” I turned and looked at my son. "I don't want you to stop either." "Son? How are you doing with your mom on your lap?" "Fine, Dad! Mom’s been shifting around so it doesn't get too. . I’ll call you back. Just ... Just, don’t go anywhere.”Clarissa clicked her phone off and put it away. “She said not to go anywhere, so how about I cook us something nice to eat? What’s in the fridge?”My wonderful girlfriend—I assumed she was my girlfriend again from the way she was acting—whipped up something sumptuous in record time from ingredients I would never have thought to put together. Hell, I didn’t even know half of them were in the fridge. Moments after she’d put the plate in front. "You mean like, 'do it, harder, faster, yes, yes, oh yes'?"She giggled, "Well, yeah, and other stuff too."I smiled approvingly. "I can hardly wait," I told her dropping her bra to the floor and sliding my hand inside the front of her panties. She squealed and grabbed at my back with her sharp nails. The pain felt like heaven, pure ecstasy.***************Steve fingered my pussy, making me wish that I could let him fuck me there, the normal way but I knew that it was impossible. Soon I was.
