Under the neon lights of Shinjuku, Tatsu and Ami, seemingly innocent friends by day, engage in a clandestine dance of desire and commerce. Ami, in her sailor fuku, seductively unbuttons her blouse, revealing her small, firm breasts. Tatsu eagerly takes them in his mouth, making Ami gasp. She unzips his pants, freeing his throbbing cock, and guides it into her warm, tight mouth, sucking enthusiastically. Tatsu returns the favor, burying his face between her legs, licking and fingering her until she cums violently, her cries muffled by his cock still in her mouth.
