SW-208 Her older sister, after a bath, was wandering around in front of me with just one towel on. I couldn't help but get an erection. She had been targeting me from the start.

When I went to her house to play, her older sister came out in a sexy post-bath state. The skin peeking out from the bath towel made my dick rock hard. Noticing me watching, her sister deliberately showed off her ass and teased me. While her girlfriend was distracted, I approached her sister and showed off my erect dick. Her sister also got aroused, gripped it tightly, and couldn't hold back any longer, so she secretly inserted it.
