What happens when a big-breasted mother and her equally-endowed daughter want to fight over the same guy? Thanks to hentai authors Blue Gale (SPOTLIGHT / PUNISHMENT) and Producers Shiyuuta Biwajima and Chikara Niki (SEX WARD / GIRL NEXT DOOR / HOOLIGAN), you`re about to find out! The Battle of the Busts! Yusuke has a problem – the kind of problem any guy would love to have. You see, there`s this girl named Reina, who wants him to be her “private tutor”… oh, and she just happens to have gigantic breasts. Huge, massive, watermelon-sized gazongas that taste sweet and are as soft as marshmallows. So, what could Yusuke`s problem possibly be? Well, when he goes to Reina`s house to give her “lessons”, he has a run-in with Reina`s mom. And boy, is her mom ever stacked. Those triple-F-cup beauties are even bigger than Reina`s! Plus, she`s got the whole “sexual mid-life crisis” going on… she pours it on hot and heavy, and really wants Yusuke to take her for a ride. Still not seeing the problem? Well each of these lovely ladies wants Yusuke for her own, so when mom catches Yusuke and Reina in the act, the fight is on -and Yusuke`s trapped in the middle! Those two may be mother and daughter, but when it comes to winning Yusuke, they`ll go to any length to prove their sexual skill! Good luck ladies, and may the best boobs win!
