Growing up I lived next door to a family with two, 20 something, year old women, who would at times leave their washing hanging out overnight on their clothesline. Sometimes at night I would sneak over the fence and remove a pair of panties and/or a bra. I loved the feel of the silky material as I ran them up and down my, by now, hard cock.
Standing under their clothesline wanking with their panties and bras wrapped around my cock, it never did take long for me to cum.
