My girlfriend and I are living together with the idea of getting married, and her younger sister is coming to stay. This younger sister is crazy, she has super beautiful big breasts and a baby face, and it's like she got the boobs for her small-breasted older sister. She's a real boob-loving killer. Even though her older sister is there, she finds an opportunity to seduce me by putting her boobs on me, and I can't help but be irresistible. I'm in boob heaven with her marshmallow boobs between me, and she squeezes my balls until they're completely empty.
