Stuck in a stale marriage and buried in work, a lonely man secretly hires an escort on payday and adds an instant-blowjob option to celebrate his bonus. The voluptuous G-cup woman arrives in erotic lingerie, sucks and swallows immediately—then turns out to be his best friend's sexually frustrated wife, Riho. In exchange for his silence, she gives him a slippery lotion titjob that completely buries his cock between her breasts. Later, she invites him to her home and secretly allows the intercourse that was previously off-limits. Desperate for sex, Riho climbs on top and grinds against him until he ejaculates; once fully aroused, she takes control and drains him completely.
