My wife's mother Susan is about 20 years older than my wife Joan and I. Mother and daughter are both gorgeous. Since Susan's husband left her for a younger woman a couple of years ago, she's been spending more time with us. Both mother and daughter like to sunbathe in the nude at our secluded cabin in the country. I know it's a cliché; but, when you see them together naked, you'd swear they were sisters.
On a typical day at the cabin, they will both be sitting naked on lawn chairs on the back porch, and I'll bring them each a glass of wine. I always have a huge boner when I serve them. Susan smiles, and usually wraps her slender hand around my dick, and gives it a couple of playful tugs. Joan, if she notices at all, will say something like 'Mother! What are you doing with Jim's dick?' and then goes back to her puzzle book after pretending to care.
Susan's tits swell as she pulls my dick. Sometimes, I will take a sip of her wine, and then take one of her nipples into my mouth. It will be hard and extended so much that it almost feels like a hard short straw in my mouth. That's how long it gets when she's really turned on. I imagine that the wine is milk from her tit as I slip my finger into her cunt, and move it in and out as she moans with increasing pleasure as she approaches orgasm. I can feel her contractions, which follow her moaning perfectly.
This is a woman who really loves sex, and obviously misses having a man inside her. Though it will never be me, it's hard to imagine how any man wouldn't want to get his dick inside of her tight, moist pussy. Her ex-husband sure was a jerk.
Sometimes Susan will expertly jack me off after I finish with her. Sometimes Joan will say, 'Now come and finger fuck me too,' which always causes her mother to say something like, 'Watch your language, young lady! That's not how I raised you.' This always cracks me up, considering what we've just been doing. But it's just have good, uninhibited fun, certainly nothing to feel ashamed about. I am glad to give pleasure to Susan, and it's nice that Joan's not jealous at all.
