I Want To Eat My Boyfriend's Ass

He's open-minded, adventurous, and slightly kinky. I already told him this, got a sly smile and a "we'll see," but I want to eat my boyfriend's ass. I tried it on a sex partner I had before I met him, and god I wanna hear my boyfriend make noises like that. He's never felt that kind of pleasure before, and I wanna be the one to give it to him. Tease the rim, grab his ass cheeks, scratch him, mark his thighs, work my tongue, get him moaning. I could jerk him off at the same time, play w his balls, maybe use a vibrator. It would be hot as fuck to have him in submission and complete ecstasy, in a way that the average man will never experience (and the average woman will never take part in). I find it sexy that he doesn't care about taboos or judgement or doing something seen as gay by the mainstream. Sometimes he lets me dominate him if I fight hard for it. With the way he eats out my pussy and tongue fucks me, until his jaw locks up or I'm having intense orgasms, he deserves to be eaten the fuck out too. I would even fuck him in the ass if he let me, but I think that one might be too extreme for him. We'll have to see how things go.
