I felt the goose bumps on her skin. Shit, I could see her dark nipples glowing through the thin negligee in the barely lighted but still darkened room...! "Betty, you're freezing! You better get under the covers and warm up"? (What a nice, kind, horny little nephew I was). She was so scared she didn't even hesitate. I must add that she was also very innocent and naive. It was another endearing trait of her personality. And one that proved perfect in affording me this opportunity to get her under. "Feeling the frilly socks sliding up both my feet with little frilly lacearound the top. Then feeling the black patented leather Mary Jane shoesbeing buckled to my feet."There you go, you are all ready, just need to get you a silk tie andyou will be good to go back to class. Can you pick that tie off thefloor for me sweetheart." I climb off the chair and bend over to pickthe silk tie off the floor, hearing giggles from behind me. I turnaround seeing Sister Ellen rolling over laughing her butt. I grunted hard, and felt my cum pounding out of my cock and into Rich's mouth. He seemed a little surprised, then went back on me far while I finished ejaculating.After a moment, I relaxed and he let my cock out of his mouth, then he visibly swallowed. I asked, "You don't mind the taste?" I'm used to it, I've been tasting my own and sometimes eating it. My ex dared me once and I found it wasn't so bad."I got back on my knees and went right back down on him. I was determined to make him cum. I kept moving my hands in her hair and then she stopped and got up on bed and pulled my hand to get me up. And then she knelt down and started sucking my cock again. Then i put my hand in her hair and hold it tightly and started fucking her mouth to and fro. She then stopped me aand started giving handjob to me . I opened her hair from band started playing with them(i love this activity the most). Then i caught hold of her hair and pulled her up and smooched her . She kept holding my hardon.
