You lose to the fuckboy's dick, you become his girlfriend!! Or will the straight guy win!? (No.)

A straight guy accepted to give his ass to a fuckboy to protect his sister, but then the fuckboy started to really take a liking to him and decided to seriously break him in...!

"Break up with Sana *now*! Hah... I can't believe my sister fell in love with such a womanizer...!"
"Fine, but if you really want me to stop doing her... You're gonna have to let me do you instead!"

Take Shijima, a university student, stumbled upon Yor Sakashiro, a man who has a reputation of being a fuckboy, flirting with his sister in the street. He then confronts Yor to urge him to break up with her, to what Yor agreed on the condition that Take lets him fuck him instead.

"But... But I'm a guy...!"
"Well... You know what they say: a hole is a hole!"

"You- You gotta be kidding me!? There's no way this is gonna fit inside my ass!!"
"What are you talking about!? It's already inside!"

Despite being straight, Take loses his backside's virginity to Yor, who likes to dominate and get his bottom off. And now Yor won't let him go...
