[Sakamata Nerimono] Zenbu Gal na Nee-chan no Sei (COMIC Shigekiteki SQUIRT!! Vol. 19) [ddock17] [Updated]

A gyaru older sister services her own little brother while her tan, busty gal-pal watches. The girl next door invites herself over one steamy summer day, and what starts as awkward teasing quickly spirals into a full-on defloration of the young boy. With full curves barely contained in her disheveled uniform shirt and skirt hitched up around her hips, the bespectacled, ponytailed onee-san takes charge—mounting, bouncing, and grinding on him while her tattooed friend Lina whispers dirty encouragement. The busty tomboy with the short crop and dark skin can't resist diving in herself, smothering his face between her enormous, sweat-slicked tits while begging him to cum for her. It's an indecent, shameless romp where the little bro never stood a chance against two stacked, hormone-drunk big sisters—his virginity claimed, his composure shattered, and the fun only just beginning as the dark-skinned domme decides she's not done with him yet.
