[Satuyo] Preemptive Triangle (Peaceful Ecchi! - PEACEFUL H) [Raknnkarscans]

Asuka's best friend lures her into a shameless after-school display, legs spread and giggling about everything there is to see, before pulling her into the shower where curious fingers turn sticky and bold. The real scheme surfaces mid-lather: Yu-senpai has been pining for Asuka all along, and the only way to settle a preemptive confession is to drag the flustered big brother into their bath for a frantic ffm threesome. By the final soak, the sister and her scheming best friend have divided him between them — one boyfriend, two girlfriends, and a very overwhelmed boy who never saw it coming.
