SW-800 My friend’s older sister had a curvy figure and a large backside that caught my teenage attention. When we ended up alone together, she suddenly changed into a very flirtatious woman, so I kept going until I was completely worn out.

My friend’s older sister teases her younger brother, but she’s actually a total masochist. At first, she didn’t seem to see me as a guy, so I got an accidental glimpse of her underwear. When she noticed I was staring, she seemed to get excited and started teasing me with her cute back view. Sneaking around while my friend wasn’t looking, I’d lift her skirt and touch her, and she would get incredibly excited. Even with family nearby, she would happily react to playful spanking and intense teasing.
