Intercrural or thighjob
I had a guy "thigh fuck" me from behind last year. First time ever. He oiled my thighs up and suddenly just sticks his cock in there and pushed my legs closed. His dick was big, so I could jerk it on the front side of me as he kept thrusting. And, I lifted it up so it rubbed against my clit. It was pretty sensual and the clitoral stim made me cum. Then I rode the fuck out of him! Haha!
Intercrural sex is not new and is vary stimulating for both parties, you should all try it
