Several years ago I had an arrangement with a younger woman. I would drive over to her dorm and pick her up on a Friday night, we’d fuck like rabbits all weekend and I’d have her back Monday morning for class.
She would orgasm in 2 ways: squirting or shaking. When it was shaking, literally her whole body would go rigid and just kinda vibrate for about 30 seconds or so. She also used to get very shy/embarrassed after cumming which I found very cute..
One night I had her laid out on her stomach with her hips propped up so I could finger her while I tongued her asshole (she liked when I would use my teeth to very gently nip between licks) and I told her that I wanted her to ask me permission before she came again. She agreed, but a few minutes later she’s shaking all over my fingers with no warning at all. I asked her, “Did you just cum without asking permission?”
Her sudden shy silence told me she had, so I starting spanking her as I continued to lick and finger her. She started whimpering and squeaking so I asked, “Do you know why I’m spanking you right now?”
