to MarkieMarkM :A great comment wnich I fully agree with. Watching each other wank can be just as erotic. I love seeing my wife cum. Makes me even harder.
Sometimes, my wife and I decide to just pleasure ourselves in front of one-another - rather than having oral sex or penetration. We always tend to cum together. It's beautiful. Ground-rules.... I'm only able to wank myself over her nipples with my foreskin...and she's only allowed to rub her clitoris on my knee! Beautiful.
