My wife loves seeing a stiff cock sticking out of women's panties. When we were first married, she'd get stretched out naked in bed and have me put on a pair of her panties, stick my hard-on out the waist line, and then grind into her mound and bush until she had an orgasm. It felt so fucking good cuming on her like that. I loved how fucking hard I could grind into her when I was cuming.
