My sister-in-law, who suddenly became part of our family, is kind and takes good care of me, but she doesn't seem to realize she's busty and sexy. She's always so defenseless, flashing her chest all the time! That alone easily makes me, a virgin, get aroused... When I thought she'd hate me if she found out, my kind sister-in-law, with sympathy, said, "It's okay if you just rub against me," giving her consent to dry humping! Excited, I rubbed my penis against her, and soon enough, her moist vagina slid around it and I couldn't stop! I thrust my hips hard and came inside her multiple times!
