I discovered vacuuming myself about 12 and I would go down the basement at every opportunity and let the vacuum suck the cum out of me. I would make it last as long as possible. I loved the sound of my cock begging and moaning. Lucky vac got to eat a lot of young cum. Finally my cock was too big to fit in the tube and I took up socks and fuck buddys. It still makes me stiff to think about it
When I was in High School, I was the first one to get home in the afternoon. I would go up to the attic and use my Mom's Electrolux vacuum with the round attachment with the bristles. Man, hold it in just the right place and it vibrated my 6" X 6 1/2" cut cock until I exploded into the nozzle. Felt so fucking good. Years later I asked my Mom if I could have the vacuum and she said yes. I still use it to suck my meat until I sperm hard! I wish I had a Buddy like you to mutually vacuum each other off!
