Yui Hatano takes on the challenge of making delayed-ejaculation porn actors cum using her G-cup breasts and pussy. Waiting at the studio, she gets the first actor hard with a handjob, but he escapes—so she storms into his shower and makes him cum with a bubbly body wash and titfuck. Still unsatisfied, she follows him into the dressing room for more titfucking, only to be counterattacked with toys and made to cum again and again. Finally, she faces two actors at once with double blowjobs and double titfucks. Can Yui keep her promise and make both stubborn men finish with her breasts?
