Masturbating With My Wife

We have been married for 40 years and together for 42. I am my wife’s only sexual partner, I like that I am the only man to have had sex with her, but she, and I get turned on by the fantasy of a threesome. Due to her health issues, penetrative sex can be painful for her and although we still have full sex, masturbation is our most frequent outlet. 

I love to watch her undress, my cock is always nice and erect by the time she is naked. Often, she’ll lay on our lounge floor, her legs spread and she’ll start to pleasure herself. Her fingers will run around her vagina, probing gently, the start rubbing her clitoris, before spreading her lips and exposing herself to me. I’ll pretend to read a book or watch the TV, but it is not long until I put the book down or turn the TV off and concentrate on watch her.i’ll soon get naked and start gently playing with myself. She will ask me to tell her a sexy story and more often than not it involves her being fucked by a stranger. I too get excited by the thought of watching his penis enter her vagina. She like me to be quite crude, which is not like her in real life. By now she will have stopped masturbating with her fingers and started using her electric toothbrush directly on her clit. 

I will be telling her how his cock feels, how she can feel it throbbing inside her and the warmth of his cock filling her vagina. I delay his orgasm until she’s about to cum, I can tell as her skin flushes red and her hips start bucking as she imagines riding his cock. She often squirts at orgasm and I try to catch it in my hand and use it as a lube as I masturbate myself to orgasm. I like to look her in the eye as I stroke my cock, sliding my hand up and down the shaft using her ejaculate as lubrication. When that starts to dry, I grip the shaft between thumb and finger and bring myself off. She will cup my balls and tell me to stop as she doesn’t want me to cum yet. She knows that this only makes me want to cum more. If she puts her palm against the top of my penis it’s guaranteed to make me shoot there and then. I like to shoot  my cum over her tummy and vagina. When I’ve finished she will usually masturbate again as she can orgasm several times in quick succession. By this time my cum is drying on her skin and I will lick it from her. The taste of my cum on her body will get me hard again and if she is feeling okay she will tell me to fuck her.  If not, I will masturbate again talking to her again about the guy, but this time for my benefit. Usually involving a story about her wanking us off together and covering her with our spunk.
