Ruka Kanae, the younger sister who has always secretly watched her older brother from behind, decides she wants to make him feel even better this time. Gently touching her nipples, she pulls down his pants and lovingly gives him a blowjob, his cock already hard. As her breasts are being groped, she gets increasingly aroused, pleasuring herself while giving him a handjob, and eagerly slurps on his shaft and balls with loud, wet sounds to make him feel even better. Finally, she takes his cumshot deep in her mouth.
