Big-breasted, Naughty, Lascivious Sister Who Secretly Cuckolds Her Boyfriend From Her Best Friend, Maki Sakura

When I got home to the house where I live with my girlfriend, she was in the middle of a girls' night with her best friend! Big breasts and defenseless! Her way of speaking is gentle and she's incredibly charming! But it turns out that best friend is a little devil woman who loves stealing other women's men! Unlike my girlfriend, she's bold and pushy, and I gave in and did it!! I know I shouldn't be touching her, but when tempted, I can't hold back!! The sense of immorality and guilt just become fuel for excitement during sex, making it even more erotic!!
