[Corundum] The Brothers Visit the House of the Onee-san That Always Gives Them Tokens at the Arcade [ekiB]

Two young brothers accept a video game challenge from the big-breasted onee-sans who always spoil them with arcade tokens—winner gets a reward, loser faces a punishment. What begins as an innocent couch showdown against a dark-skinned gyaru and her twintailed friend turns into a hands-on lesson in pleasure once the boys drop their controllers, with each woman eagerly guiding a flustered first-timer through blowjobs, paizuri, and more. By the final round, one brother is pounding into them from behind with such beastly stamina that both women are left breathless and pinned beneath him, wondering exactly who ended up punishing whom.
