A hot take on the mom sitting on son’s lap sex story. One of my favorite plot devices …
1. Wearing a short, skimpy dress had been a bad idea, as I was now sitting on my son’s lap, my skirt not quite covering my butt, and a narrow thong the only barrier between my vagina and my son.
2. My son’s penis was hard and I could feel it pulsing directly under my vagina.
The takeaway: 18 year old son is going away to college – son has a lot of stuff – dad drives while mom and son squeeze into the back seat – where theres only room for the mom to sit on her son’s lap! cheating, incest and more!
