Hajime to Masamune (to Oppai)

I want to rub breasts! Masamune, a high school boy who is curious about sex, is dying to touch boobs. However, when it comes to the boobs that are close at hand, it's only his childhood friend, Hajime's (another boy). That's okay! When Masamune tried touching it, it was hard, strong, and not fluffy at all. But? "Maybe I'm in love with Hajime-kun's (boobs)??" Blossoming love of two childhood friends over boobs!
