The back of the emergency stairs of the apartment building is my secret spot for taking secret panty shots. My sister's friend Mitsuki found me, but I was curious if she was a naughty girl. When I lifted her skirt, I could see that she was excited even though she didn't want to. When I was talking to my sister's friend in her room, she noticed that I was looking at her and started showing me her panty shots and teasing me. I invited her out to the hallway, and next to my sister's room, I rubbed her firm ass and hot slit with my fingers, which made her very excited. Unable to hold back, we went to Mitsuki's house and continued having sex in her room... She showed off her naughty side by sucking on my erect cock and welcoming it into her smooth pussy. At the end, I released my hot semen into her mouth and she drank it all up, like a dirty girl!
