FNS-268 Unaware of how alluring she looks in her workout clothes, my friend’s older sister drives me wild, and I end up unable to resist her sweat-drenched, fragrant, voluptuous body. Yatsumi Rin

My friend’s older sister has a great figure, a pretty face, and a stylish look. Every time I visit my friend’s house, I see her doing exercises for beauty and fitness. Her outfit is so revealing that it feels almost too much. The top is barely more than a bra, showing a lot of cleavage, and the bottom is almost like panties, with her backside nearly exposed. On top of that, it’s gray, so the sweat from her hard workout soaks in clearly and is easy to notice. I couldn’t resist and things quickly turned intimate. She surprisingly went along with it, and it became a secret workout session with orgasm training kept hidden from my friend.
