Been letting my boyfriend make me his bitch

Both of us are very masculine guys. Played sports, we’re in fraternities, etc. We’ve always been vers and total equals.Within the last year I’ve basically become his bitch though. It started when he was rimming me, and it felt so good that I couldn’t stop moaning. One of those moans was pretty high pitched on accident. He paused, looked up, and almost growled as he dove back in. After that, he started saying things like, “Do you like it when I eat your pussy out?” Swept up in the moment, I just moaned and told him how much I loved it despite having never called my hole that before.He started exclusively topping me after that. We never made that decision, it was just a series of, “I feel like topping today” that after time became a phase, which eventually just turned into the default. I haven’t topped in over a year now, and he almost always starts by eating me out. If not, he has me put in a plug to warm up while sucking his cock. He likes to have me hitting poppers to get opened up. I have to say that hitting poppers, in a jock strap, with a plug in my ass and his big cock in my throat is bliss. I could do it all day long.His regular fuckings got more and more primal over time with more dirty talk like:- “Tell daddy how much you love his cock.”- “You love daddy’s cock in your pussy, don’t you?”- “Oh is that a little whimper? Does daddy’s cock make that pussy feel good?”- “Your pussy was made for this wasn’t it.”- “I’m going to fuck you daily until your pussy is the shape of daddy’s dick, boy.”Most recently he told me, “I’m going to knock you up and make you pregnant.”I’m not mad. When he says those things, I’m usually staring up at him, legs spread wide, with my hands on his furry pecs begging for his load inside me. And I love it enough I have often found myself cumming hands free into my jock strap or all over our chests.It’s just wild that only a year ago we mostly flip fucked and now our roles are so different. I feel totally bitched out by him. Or as he puts it, “You let daddy cunt you, didn’t you?”
