Summer vacation! Reo, a drenched female student returning from club activities, sneaks into Mr. Umeda's house nearby to take a shower. Seeing her see-through, perky, and voluptuous body, Mr. Umeda says, "Huh? I think I'm getting an erection," and, ignoring her resistance, sticks his erect cock out and lets her suck it with her pussy lips that are ready for sucking! Reo devours the throbbing cock with her mouth, savoring every bit of it. The summer vacation of this super-full-breasted J-girl's lewd activities begins!
