Four adult women worth keeping as mistresses star in 320 minutes of intimate homemade porn. Yocchan, 26, is an athletic submissive with a trained body and enough stamina for two loads. Rino, 25, is a shy, insecure bombshell who has been single for four and a half years and takes two heavy loads. Umi, 28, is a reserved finance worker who unleashes the dirty appetite hidden beneath her serious image. Nakamaru, 23, is a curvy concept-café worker and avid masturbator with plenty of energy for a second round. Their overflowing sexuality powers a marathon of intense private sex.
