RTP-103 I caught my sister masturbating intensely with a dildo. ‘I can’t hold back anymore! I want to have sex!’ she said, all worked up. Then, at her insistence, she used my penis as a substitute for the dildo…

My younger sister who is crazy about masturbation so much that she doesn’t notice that I’m looking into her. Even though I’m a virgin, I was so excited that I was holding a thick dildo in my mouth and panting in front of me. I thought I would be rejected, but her sister’s eyes shined when she saw a real cock for the first time in real life, and said, “I want to insert it…” and straddled me…! ?
