I've always been turned on by seeing how far I can squirt my cum when I hop into bed each night. Sometimes, if it's been a few days, I am amazed at how much cum I can unload. Needless to say, the wall behind my bed has become a pretty disgusting mess of dry splatter.
I sometimes feel guilty about it, but I get a thrill out of hearing the spray of cum hit my walls. Usually every couple of months, I take a bucket of cleaning solution and scrub it all down simply because it's embarrassing when my friends visit and come into my room. They say, 'Uh, what the hell is all that crap on your walls?' I usually try to change the conversation, but sometimes I'll just admit its a lot of cum splatter. The guys will laugh and ask why I just don't use a kleenex like everyone else. I say to hell with kleenex. If you've got an overactive nut sack, use it!
Anyways, it's crazy that I do that. When I'm scrubbing it all down, I like to stand on my bed and see how high the jizz shoots. A few times I'll find a nice load a few inches from the ceiling. I know I'll have to stop when I move in with a girlfriend (she likely wouldn't appreciate the mess), but until then I'll be 'marking' my territory with every chance I get.
