When I Pulled My Rubber Off To Fuck My Big Sister Raw, She Transformed Into A Slut! My Big Sister Is Studying To Get Into A Really Exclusive College, So Every Minute Counts Since She Spends All Of Her Time Studying, She Has No Time For Dating, And Even Masturbation, So She's Taking Out Her Sexual Frustrations On Me, And Making Me Put A Rubber On To Fuck Her

ゴムを外して生挿入したらお姉ちゃんが豹変！超難関大学を受験する姉は一分一秒を惜しんで勉強をしている。あらゆる時間を勉強に捧げている姉は、恋愛はもちろん、オナニーなんてしないのでとりあえず溜まった性欲処理に弟のボクをいつも呼びつけてゴムをつけて挿入させる…

My super smart, brainy older sister devotes all her time to studying for her tough university entrance exams! She has no time for romance, and of course she doesn't masturbate, so her sexual frustration just keeps building up. That sister of mine calls me, her little brother, to her room as her sex drive handler, and relieves her sexual urges and stress with condom-on sex! But even during insertion, she's always studying and doesn't react or feel anything. It feels kind of lonely... so I secretly took off the condom and went for raw insertion and a creampie! Then, my sister, who felt everything with my bare dick, got totally hooked on sex!
