This has been a regular part of our sex life since we started dating. KK has a huge fetish for watching men masturbate, either as an unseen voyeur, or in sessions where we're all masturbating together, performing for one another.
I love our intimate, one-on-one one masturbation sessions - we show one another how we like it, use toys, lube, fingers and hands, to make ourselves cum while watching each other experience blissful pleasure.
