Faint Fuck

My stepson was 17. His dad was working and he and I were home alone. I decided that after my morning run I would hit the hot tub in my bikini and with a small glass of wine. Well that glass was refilled more than it should have been. My stepson came home from the gym and joined me in the tub. After a bit I got very lightheaded and as I tried to leave the tub I fainted. My blood pressure has always been low but I guess the heat of the tub and wine made it too low. When I came to I found myself on my bed nude, perfectly dry and my stepson sucking on my toes. I was startled of course but for whatever reason I did not stop him. He kissed and licked my feet, calves and inner thighs as I writhed in anticipation of his mouth reaching my wanting wet pussy. He ate me so well that in no time I came and came hard. He then rolled me over, I got on my knees thinking he would take me doggie style but much to my shock he licked my anus. This was a first for me! It was okay. He seemed to really get into it with no rush to stop. He final sunk his erection into me and pumped me for all he’s worth until he came. As soon as he came he left. He and I have never spoken of what happened and have never repeated the act which as of today has been over a year.
A one off I guess and probably for the best.
