[Mononokedenka (Matsuzo)] Sunny Became Mine (Tokyo Revengers)

Takemichi works up the nerve to tell Mikey what's been weighing on him, with Chifuyu vowing to back his play as his partner—only for Mikey to appear before the words land, backing the trembling boy against a wall until tears and a giddy 'maybe he likes me' spill free. The gang leader's answer is patient and adoring: slick fingers stretch Takemichi open while the blushing boy whimpers that it won't fit, and Mikey coos that he's cute before pushing inside anyway. Possessive from the first tight embrace to the final thrust, it's Mikey claiming Takemichi as his, body and heart.
