Wife caught me and helped me out--sort of!
My wife knows I masturbate, and has caught me several times, and sometimes just lets me jack off beside her in bed if she's not in the mood. She tells me, "Just jack it off!" so I do. One time she came home and caught me playing with myself while spanking myself with a fly swatter. "Let me help you with that!" she said and took the fly swatter. She turned my ass RED! I could barely stand it, but at the same time it was good. She told me not to cum yet because she wasn't finished with me. She then took a belt and lit my ass up; I couldn't hold back and came on the floor, which she made me clean up. The belt was a bit much--that shit hurt! We still do it on occasions, though; I think she gets off on whipping my ass...

My wife likes to watch me masturbate. She spanks me pretty regularly too.
