HOMA-061 My girlfriend's sister is boldly seducing me!! I steal her eyes and cum inside her Emi Sakuma

I love my girlfriend, but we're in a slump. When I visit her house, her younger sister, Emi, adores me. At first, I thought she was just spoiled, but... I never imagined she was a total slut! Her innocent seduction overwhelms me, as it's been so long since we last had sex. And Emi's not just with me, she's also with her mother's boyfriend... It's a huge violation of morals, but there's no turning back now! I cum inside this convenient slutty girl over and over again!
