Done after 1st stroke
Tonight I had sex with my wife. I was horny all day, and when she came to bed, I immediately started playing with her breasts, sucking her nipples. After a while, I removed her pajamas and started fingering her very wet pussy. First with two fingers, then with three. I sucked her tits the whole time while increasing the speed of my fingering. She came hard after about five minutes. Then I licked my fingers clean, she tasted heavenly good, like always.
Then she said she wanted to ride me. My cock was dripping huge amounts of precum, and I was already close to orgasm. So when she gave me a couple of strokes while positioning herself on me, I was already on the edge. When she finally mounted me, I started cumming on the very first stroke.
She couldn't hold back her laughter, but she didn't say anything. It was a very hot experience, and I hope I'll be able to cum even faster next time.
