Men, How Are You Masturbating In Your Beds?

Alright, maybe I'm just stupid, but I need answers. I've always masturbated on the toilet because it's easy, no mess to deal with. But as you can imagine, it's not as comfortable as a bed.

How are you guys doing it without making a mess on your sheets? Maybe I'm overthinking this since I'm back living with my parents so I have to be more concealed about it, but I'd like to sit on something softer than porcelain when I'm trying to get a nut off.
