Yumi runs a no-panty cafe and harbors two secrets about her relationship with her son. One day, both secrets are exposed, but the situation takes an unexpectedly positive turn. Since they're not related by blood and have long harbored feelings for each other, their suppressed desires finally erupt. The long-standing yearning to touch, to be touched—explodes into passion. She reaches climax after climax from intense cunnilingus so fierce it leaves her unable to perform a blowjob, blissfully accepting endless, deep thrusts. Moaning and dripping with arousal, there's no time to rest. Penetrated again and again, she orgasms without end in a relentless, fervent fuck that finally satisfies the deep-seated craving buried within her.
