SW-208 My girlfriend's older sister walked around in front of me with just a bath towel after taking a bath, and she was aiming for me from the beginning because I couldn't help but get an erection.

When I went to visit my girlfriend's house, her older sister came out looking sexy after taking a bath. My cock is throbbing on the skin that comes out of the bath towel. When my older sister noticed that I was watching, she purposely provoked me by showing me her butt. Stealing her eyes, I approached my sister and appealed to her with my erect dick, and she too became horny, so I grabbed her dick and couldn't resist anymore, so I inserted it secretly.
