Masturbandosi con la corda e il giocattolo vibro

When I get super horny, I use some rope to tie myself to my bed and a vibrating toy to slowly edge me until I can't hold it anymore. I love cumming with vibration only, and I know I can cum even with a very weak toy, but I don't normally have the patience if I'm by myself... Who's gonna teach me to keep my hands off my cock?
