My high school friends often had sexually-attractive mothers, women in their thirties and forties who sometimes left their frilly intimates in bathroom laundry baskets; frequently made of wickerwork. It was exciting to search these silky treasure troves for a sexy pair of knickers with which to masturbate. Leaning forward looking int the bathroom mirror allowed me to see my hand pumping my hard-on. I knew, perhaps unfairly, that the cum stains left on these garments would never be blamed on me. Sometimes there were frillies belonging to sisters, cousins, aunts, grannies. I have to confess that I sometimes took a pair for masturbation later, knowing that my foster mom didn't get upset about my little fetishes. Sometimes, whatever male friend I was visiting would jerk off with me, both of us using panties to jerk ourselves to spurting climax or jerk each other. Several of my friends needed little persuasion to have a joint wank. In the 1950s and sixties it was still very difficult to persuade a girl, or older woman, to do it for us. A mutual masturbation session could be organized in as little as 10 or 15 minutes, whereas persuading a young lady or older woman to whack one off or suck one's penis could take days, weeks or even months. it was no contest (or nolo contendere as they say in Tuscany). Another form of bathroom masturbation was just soaping it up in front of the bathroom mirror and having at it, shooting a load of cream directly into the sink. None of us was interested in anal intercourse but we did experiment from time to time with inserting objects on our bottoms. A hot dog is ideal but you have to rinse the spices off if you don't want a burny bottom. Enclosing a hot dog in a condom is another solution. For masturbation in bed I'd just use my underpants or a sock. When I was university age I tried using one of my mom's white cotton bras until she caught me and explained that ejaculate left spreading brown stains on white lingerie (like a spreading mushroom ring in the woods, or actually rotted some lingerie material away. Her comment, the first time she caught me was "everybody masturbates," and as an afterthought while leaving my room " . . . and the rest are liars," after which she guffawed. My foster Dad wasn't around to add his two cents because he was pretty well always off fighting wars; one of the main reasons they fostered me in the first place. My main memories of that period of my life were that both myself and my friends masturbated with alarming frequency and, not knowing al the science involved, sometimes believed we were doing ourselves harm.
Not a neighbor but I love smelling and sucking my wife's panties as I masturbate. Sometimes then shooting my load into their crutch and licking and sucking them. Tasting her left over juice and scent missed with my cum
