The family next door would drop their daughter off some weekend if they worked. She was about 13 and had quite a cute figure developing, she often worn denim jeans that stuck to her like glue showing off her cute butt. She would usually lie on the sofa watching cartoon network, one morning I went to ask her if she wanted anything to eat and caught her masturbating, she was lying on the sofa face down with both arms tucked under her front and I watched her cute butt grinding down and her thighs flexing, the jeans were so tight I could make out the lines of her panties and she had a small hairbrush jammed between her thighs.
My cock swelled up and I squeezed away as I watched her riding the hairbrush and dreaming of her cute puss swollen and encased in her panties and the tight denim rubbing her. Her thrusting became more powerful and she had the hairbrush jammed between the sofa cushions so she could ride the handle, then she held onto the brush and thrust deep into the sofa and I saw her thighs jerk and lock out, I guessed she orgasmed and I twitched and shot a load into my shorts. A short while later she came into the kitchen, we chatted and giggled and I couldn't help stare at her still stiff little nips and puffy pussy cut into two by her so tight jeans.
