Can we get more of reggie being horny from testosterone 😔😔 and maybe add a partner hehehe
gonna make this evanreg if you don't minddddd.
Imo, Evan fits this scenario the best because he would 100% be the one to pick up on Regulus' weird behaviour. He keeps going silent in conversation, which in itself isn't unusual but it is when he doesn't have any witty retort to Barty's insults. He's showing up late to nights out, which never happens. He shows up antsy and distracted, his hair messy and his cheeks flushed. He stares at Barty's lips, Evan's arms. Evan understands quicker than anyone else, poor baby Black is horny for the first time and doesn't know what to do with himself.
Evan asks Regulus to hang out at his place, when Regulus gets there, he's 20 minutes late and his voice is raspy. Evan lies, says Barty couldn't make it, that it'll just be the two of them. Regulus immediately gets anxious, wiping his palms over his jeans, stuttering over his words as they sit in Evan's bedroom.
It doesn't take long for Evan to ask how taking testosterone is going, if there are any side effects, that he read lots of people get horny. Regulus srumbles instantly, begging for him not to tell the others. Evan wouldn't, that would ruin his fun. Instead he tells Regulus he'll help him, if that's what he wants. And obviously, it is.
Regulus has Evan in his mouth before he can think, moaning around him desperately, tearing up as he takes more than he should. He's begging and pleading, he's too overwhelmed to know what to do. All he knows is that Evan is manhandling him and his cock is so big and he wants it inside of him.
Evan is going on about how tight he looks, that it's obvious he's practically a virgin. He makes Regulus scream and sob. He fucks him so hard, just like Regulus imagined him doing. He fills him up so well, so fucking huge, no toy could compare to the real thing. It's when Regulus realises that he could live on just Evan's cock and nothing else for the rest of his life that he comes.
Evan doesn't stop, he keeps going, dragging orgasm after orgasm out of Regulus, letting his own cum leak out of Regulus' hole before stuffing back in. He gives extra special attention to Regulus' bottom growth, stroking it, sucking it into his mouth. They spend all day in bed, Regulus completely insatiable and needy, Evan so happy to fuck someone over and over, having someone beg for his cock like they need it to breathe. The person being Regulus is just the cherry on top, Regulus who is always so composed and cold, all whiny and pliant as soon as he sees a big cock.
