What happens when a huge-breasted mother and her equally well-endowed daughter want to fight over the same guy? Thanks to hentai authors Blue Tempest (CENTER OF INSPIRATION / PUNISHMENT) and producers Shiyuuta Biuojima and Chaikara Nikia (SEXUAL OPPORTUNITY / GIRLS ON THE COUNTRY / HULIGAN), you’ll soon find out what’s up! Battle of the Busts! Yuzuki has a problem – the kind of problem any guy would want to have. You see, there’s a girl named Reina who wants him to be her “private tutor” … oh, and she, gifted by fate, has giant breasts. Huge, massive, watermelon-sized ones that taste sweet and as soft as marshmallows. So, what could be Yuzuki’s problem? Well, when he goes to Reina’s house to give her “lessons,” he has a run-in with Reina’s mom. And boy, does he run into her mom’s charms, which are even bigger than Reina’s! On top of that, she has a whole “sexual midlife crisis” developing at full speed … and she really wants to ride Yuzuki’s masculinity. Suspect anything yet? Okay, each of these lovely ladies only wants Yuzuki for her, and when Mom catches Yuzuki and Rein in the act, there is a struggle – and Yuzuki is in the middle! Those two may be mother and daughter, but when it’s a question of who gets Yuzuki, they are ready and able to do anything to prove their sexual skills! Good luck to the girls, and may the more deserving breast win!
