Yume cannot resist sucking her best friend’s boyfriend, and he soon becomes addicted to her troublesome oral obsession. Across seven scenes she steals him away with blowjobs while his girlfriend is absent, in her usual seat, during a bathroom ambush, and right beside the girlfriend after she passes out drunk. The secret oral sessions continue in different locations until morning and escalate into sex, leaving him drained of ten loads and physically unable to resist the pleasure.
