I had a goonette acquaintance come up with an idea I’d never had in 35 years of male masturbating: lie on my back naked under a blanket, let my penis harden and bob and throb and leak, until there’s enough of a vicious puddle of precum on the underside of the blanket for me to hump while it lubricates my coronal ridge and frenum, until I reach the edge with no further touching (apart from autonomously humping my bator blanket), or more likely, ruin my orgasm with a gooey gloppy ejaculation of bator semen. With practice I think i could learn to master a really hard leaky visually arousing edge.
