When I bent over to pick up some hangers from the floor, I noticed in the mirror that his outstanding dick was up at a forty-five degree angle and tha... his eyes were centered on my heart-shaped bum with my tiny thong the only cover.Since we were all alone and it would be at least ten minutes before the altered pants would be returned to us, I smiled over my should and back up until my posterior was firmly surrounded by his “old-man” thighs and his huge cock was firmly lodged in my ass crack. My Didi again started sucking my cock and this time it was 69 she was on me taking my cock in her mouth and I was licking her cunt this was giving pleasure to her also as she was giving jerks from her waist. I was licking her clit biting, pinching her labia and fingering her wet love hole.After a long licking and sucking session she tried to sit on my cock taking it in her cunt but I was not able to penetrate as my leg was in pain and I had already exerted my leg a lot in the last 1 hour. So. Sometimes, he'd just comment on how girlish I seemed to be on some particular day. His comments were never rude or demeaning, just point blank observations from him about me.I had started to get used to it. I knew there was no point in trying to let him know that his comments made my uncomfortable, as I was sure that if he knew that, for sure he would intensify the activity. So I just grinned good naturedly and pretended like nothing at all had happened out of the ordinary.We had our lunch.. She asked me to undress her. I unhooked her blouse hooks and bra. The breasts jumped out like rabbits. I held them, pressed them and put one in my mouth and started sucking. She liked it. The other breast she herself pushed in my mouth and I was sucking with utmost enjoyment. She moaned and whispered “ Son, how are my boobs, do you like them, now they are yours, massage them, suck them” I sucked them to utmost my pleasure. Mom moaned in pleasure. Her boobs were enlarging. She undressed her.
