I had a co-worker who has a daughter who is 16. She recently hit er growth spurt and outgrew alot of her clothes. He knows that I have a daughter 14 yo and offered me a box of her non fitting clothing. I didn't like the thought of my daughter wearing second hand clothing but I accepted out of politness. I was planning on donating the clothing to the salvation army. I was sifting through the items at home, seeing if anything needed washing before donating. I realized halfway through that I had a hard on. I had no idea why, but the material felt so soft in my hand. I locked my door, stripped naked and emptied the box out. I dressed up as a little girl, stretching the material to the max. I slipped on a cute pair of her daughter's shorts. My dick looked massive inside them. I wrapped a pair of her stockings around my dick and jerked before cumming on her dress. I now have a huge box of masturbation material
