Depends on where I happen to be. Maybe I lick my fingers clean or use whatever's at hand to clean up my mess.
I don’t wear underwear and my cum doesn’t get a chance to dry up I make sure I eat every yummmmy drop of my cum delicious
Mine is a dish towel that only gets washed when it gets too stiff and crusty. I put it over my face when I start jacking off just so I can smell the dried sweet loads.
Not messy at all, I just cum in the palm of my hand and lick it up. I'm usually well primed from eating all my precum as I masturbate and I produce a lot of precum!!!
The shower wall in the morning is a regular recipient of my jizz so I rinse it right down the drain. Sometimes my FWB and I masturbate together watching her choice of porn and she'll clean half up and feed me the other half. And if I spray anything on her body, that's my job to clean up as well. If she squirts and it goes on me...which is a rarity but does happen, she cleans that up.
In my early years of masturbating, I had an old t-shirt that I would use as a cum rag and hide under my mattress. I used to ejaculate a lot and my cum rag would get crusty and odoriferous.
It all goes in my mouth. I have a little plastic spoon that I keep next to bed so I can scoop it all off my belly. Once upon a time I could ejaculate directly into my mouth. Clean and highly erotic.
Sometimes I jack off into the toilet and flush. Super easy. Other times I'll cum on myself and rub it all over me, then rinse off in the shower. Sometimes I cum in my hand or in a condom and eat it.
