僕と彼女は結婚を意識しつつ同棲中なのだが、そこに彼女の妹さんが泊りにやってくることに。この妹がヤバかった、貧乳のお姉さんの分までオッパイをもらったような超美巨乳で童顔、まさにオッパイ好きキラーな女の子。姉がいるのに隙をみつけて僕に「パイ乗せ誘惑」をしかけてくるから、溜まらない、じゃなくタマラナイ。マシュマロボインに挟まれまくってパイズリ天国、金玉すっからかんになるまで絞り取れられてヘロヘロです。
I and her are living together, conscious of getting married, but her younger sister comes over to stay overnight. This little sister was crazy, with a super beautiful, baby face and a baby face that seemed to have been given even the small-breasted lady’s breasts, making her a real K**Ler girl who loves breasts. Even though I have a sister, she finds a chance and tries to “snap me on top” me, so it’s not like I can’t keep up, it’s a pain. I’m exhausted by being pinched by marshmallow busty and getting a titjob heaven, and I’m exhausted because I squeezed it all out until my balls are completely out of my mouth.
