Yuusuke has a problem that any guy would want and most guys wish for. A girl named Rena wants him to be her supposed "private tutor". Rena's an extremely well endowed girl, which is probably what drives Yuusuke into agreeing to be her "private tutor". This is where his problem begins. It's obvious that tutoring is one thing that they will surely not be doing. When Yuusuke comes over for Renas lesson he runs into her mom. Wow is one word to describe her breasts. Renas mom is blessed with a Triple-F Cup, even bigger than Renas. She really lays it out there and climbs all over Yuusuke. Here's the big problem. The fight over Yuusuke is now going to begin as mother and daughter get ready to show off their sexual skill in order to win.
