妻の実家で1人留守番をしているとお義姉さん・みおが突然帰ってきた。妻にはない色気が自然と漏れるみおに目がいってしまう。そんな視線に気づいてか、みおもまた自分に儚い恋心のような感情を爆発させた。妊娠し全てが順風満帆な妹と家庭がうまくいっていないみお。乙女心と嫉妬が入り混じった状態で避妊具なしの性行為を求め、騎乗位で中出し精子を絞りとり、孕みたがる様子に自分は激しく勃起と射精を繰り返すしかなかった。
While I was home alone at my wife’s parents’ house, my sister-in-law Mio suddenly came home. My eyes were drawn to Mio, who exuded a natural sexiness that my wife didn’t have. Perhaps noticing my gaze, Mio also exploded with feelings of fleeting love for me. My sister was pregnant and everything was going smoothly, but Mio’s family life was not going well. With a mixture of maidenly feelings and jealousy, she asked for unprotected sex, and squeezed out the sperm inside her while on top, and her eagerness to get pregnant meant that I could only get a violent erection and ejaculate repeatedly.
