That happened to me yesterday when I was masturbating - I hadn't ejaculated in over a week and I had a boner that was soooooo hard and felt great - but it took on a mind of its own
Premature orgasms. Either you love em or hate em. I love it. I like making my man get so hard and horny that he trembles and explodes sperm. Ejaculation …. especially hard ones.. trembling cocks and sperm shooting in an open cunt is so intense!! When I masturbate, I imagine I have a cock.
