入学した学校の校則「部活強●」ってマジ地獄！そんな中、耳にしたとある噂…水泳部はお飾りで顧問がお爺ちゃんだから「ほぼ帰宅部」らしい。入部したらそれだけでいいウチの弱小水泳部、こりゃ良い！部活は水泳部一択だぜ（泳げないけどね w）と思って、入部してみたら…今年から新しく顧問になったというのが女教師2人。なぜだかとんでもなくクッソエロい水着を身に纏った長身で爆乳（二人とも推定 J カップ）のモデルみたいな美女！目のやり場に困っているボクを2人で痴女ってきて…金髪ギャルビッチな清宮先生に無理やりチンポ握られたり、おっとりしてるけどむっつりスケベな百田先生に下品な言葉でシコられたり…これは天国？地獄？

The school rules at the school I enrolled in are hellish: "Club activities are mandatory!" Amidst all this, I heard a rumor…the swimming club is just for show and the advisor is an old man, so it's "basically a club where you just go home." Our weak swimming club is great because all you have to do is join! I'll join the swimming club (even though I can't swim lol), I thought, and joined…but it turns out that the new advisors this year are two female teachers.For some reason, they are tall, busty (both estimated to be J cups) model-like beauties wearing incredibly sexy swimsuits! They both started acting like perverts on me, making it hard to know where to look…Ms. Kiyomiya, a blonde gal bitch, forcibly grabbed my dick, and Ms. Momota, who is gentle but secretly perverted, jerked me off with vulgar words…Is this heaven? Or hell?
