   “Eh–!? Why'd you suddenly bring that up…”

   Tsukasa's face immediately goes red as Rui straddles himself on his lap, then rolling his hips on Tsukasa's crotch. “Mom and dad won't bother us for the rest of the night, why don't we have a little bit of fun~?” Rui throws his shirt over his head and somewhere on the bed.
