I have been wanking in bed just before I go to sleep just about every night for as long as I can remember. I usually just shoot on my chest and stomach and wipe up with a pair of underwear. If I am really excited or have been edging and I shoot on the pillows or it lands on the bed I will get a wet towel and some soap so it doesn't stain, but under normal circumstances I just wipe up and roll over.
