部活の遠征のために上京した姪っ子がしばらく自宅に泊まることになった。久しぶりに会う姪っ子は大学の陸上部に所属しているらしく立派なJDアスリートに成長していた。陸上マニアの自負があるので目の前で走りのフォームを見せてもらうことになった。ランニングマシンを使い汗だくで真剣に走る姪っ子のフェロモンに思わずチンぴく！汗まみれのデカ尻に我慢できず思わずバックから即ハメしてしまった！陸上で鍛えられた締まりの良いおま○こを瞬速ピストンすると何度も汗だくイキ！汗もマン汁も全てを味わい尽くし舐めしゃぶりSEXで何度も中出しした！

My niece came to Tokyo for a club activity trip and ended up staying at my house for a while. It had been a while since I'd seen her, and it turned out she was on the university track and field team and had grown into a fine female athlete. As a self-proclaimed track and field enthusiast, I asked her to show me her running form. As she ran seriously on the treadmill, drenched in sweat, her pheromones made my dick hard! I couldn't resist her big, sweaty ass and immediately fucked her from behind! I swiftly pistoned into her tight pussy, which had been trained by track and field, and she came again and again, drenched in sweat! I savored every last drop of her sweat and pussy juice, licking and sucking her as I fucked her and came inside her multiple times!
