my step-sister, who is beautiful and kind, worries about her body type and says, "I might have gained weight lately," while carelessly checking her figure. she also shows me her new sportswear, which is tight and accentuates her curves, making her breasts and butt look even better. plus, she's all sweaty, making her even sexier. i couldn't control my erection and ended up attacking her. but my sister-in-law also enjoyed it and came multiple times, drenched in sweat.
