Having been married for 30 years Dave and I like to experiment with different means of erotica and arousal. One simple method of arousal which we both adore is to simply sit and talk explicitly and frankly about our fantasies. Usually this is done while we are naked in bed while sitting next to each other.
As we discuss things and explain what turns us on we play with ourselves.
Dave's main fantasy is to have two women at once and as he describes the way he would penetrate each one in turn he usually cums all over his hand while he is still talking about it.
This always takes me over the edge and I describe in intimate detail the pleasure I am getting as I continue to masturbate while I'm cumming.
Sometimes we start these sexy conversations before going to bed while we are still fully clothed. I think these occasions are especially rude because Dave opens his pants and takes out his penis as our conversation hots up . I love to see him masturbate while still clothed. Its not usually too long before his semen comes shooting out. Sometimes he describes exactly how it feels as his semen works its way up his penis and shoots out of the tip. By this time I have to pull down my pants and frantically masturbate myself to a wonderful wet climax.
It does cause a bit of a sticky mess when we are clothed (especially for Dave) but its well worth it.
