HUNTA-211 "Were your boobs really that big...?" My younger sister is on a diet and her nipples are showing through her sweat! Recently, she suddenly started exercising at home to lose weight. She's desperately trying to lose weight, but the stress of restricting her diet and exercising is making her irritable, and to be honest, I don't like it. But the way she dresses while dieting is pretty sexy...

My younger sister is at an age where she's worried about her figure, so she started working out at home to lose weight! Despite her best efforts at restricting her diet and exercising, she's stressed out by the sudden diet and is frustrated every day. However, the clothes she wears while dieting are designed for ease of movement and are very sexy! I hadn't noticed before, but my sister's breasts are surprisingly big, and they're shaking all over the place! What's more, when I look closely, her nipples are visible through her sweat! Seeing her like that, I get an erection and my sister finds out, but she grabs my dick to relieve stress!
