[Sakamata Nerimono] It's All The Gal Nee-chans' Fault 3 (COMIC Shigekiteki SQUIRT!! Vol. 22)

Young Kenya is steamrolled by his voluptuous older sisters and their gyaru friends in a relentless barrage of teasing propositions, each busty "Nee-chan" taking turns dominating him and competing for his attention. The pressure escalates from flustered banter into a chaotic, sweaty group encounter where every curvy sister claims a piece of him, leaving the overwhelmed boy begging for mercy. With breathless dialogue like "Kenya that became these erotic onee-sama's meat vibrator is finally cool!?" and "Hey hey about that song we've been planning on going on how about we bring Kenya-kun too?", the story teases a mischievous, pent-up family dynamic that promises plenty more shameless, sibling-driven fun.
