"It's okay if you just squeeze it between your boobs...!" My step-sister, who was born from my parents' remarriage, has huge boobs that are visible even when she's wearing clothes! Of course, being a virgin, I don't know where to look and I can't talk to her properly! But she gets close to me and tries to get some skinship with me, so I decide to go for it, and I get distracted by her big boobs and can't talk properly...
