[MIMK-293] Secretly getting girls on the street to give handjobs without their awareness in a box guessing game featuring eight participants. Wakatuki Moa, Momose Himari, Tomoe Hikari

Didn’t see it in the credits, but apparently this is a collaboration

Believe マンボー (Manbo), which is renowned for its handjob scenes, is teaming up with our lead studio in a live-action collaboration based on the popular doujin series “箱の中身当てゲーム” (Guess What’s in the Box!)

So. Apparently lured by the of 20,000 yen for the right answer, a variety of women
(AV actresses, office ladies, schoolgirls on field trips, and even ladies in lingerie)
tentatively reach into that box that is concealing its contents . . .

A camera hidden inside the box captures stunning close-ups of their fingers, an they’re filmed feeling the illicit thrill born from the “secret in their hands” that seems unseen.
