So lately I have been getting more into masterbating while playing with my wife's panties. Recently her mother came to stay with us for a few days, usually she only stays one night. A few days into her visit my wife and mother in law were going to be out of the house for a few hours at appointments, so I saw my opportunity.
Now my mother in law isn't a sexy knockout but she has really wide hips and often goes braless or is nearly falling out of her bra under her blouse. Now several of her shirts are nearly sheer or pulled pretty tight at the buttons around her probably C cup breasts. When she is wearing a bra I am usually trying to get a peek at her nipples as her bra is sliding off her breasts. When she isn't wearing a bra I am definitely trying to get a peek at those nipples. I'd love to give one a good pinch when she gives me a big hug and kiss each time I see her.
But on this day I saw my opportunity to checkout her panties and bra. After wife and MIL left I went into the guest room and found her suitcase sitting on the bed, I opened it and found a pair of pink nylon panties. Now I assumed they would be really big to cover her wide hips and ass but they were not as big as I thought but they were the nice full coverage panty briefs. I took them back to my bedroom where I stripped down, to free my swelling cock. I also picked up a pair of my wife's panties to sniff. I stood in front of the full lenght mirror, wrapped the MIL pink panties around my cock and stroked my cock while getting that intoxicating sent from my wife's panties. It felt really good as I was stroking my cock, then I thought there is plenty of panty so I rolled them up, sorta loosely folded and held them with two hands while I fucked those pink panties while thinking about how I'd love to suck on her nipples. It felt really good on my hard cock. As I could feel the pressure building I switched to holding the pink panties with one hand while fucking them with my cock and smelling my wifes scent from her panties held in my other hand. Just as I reached the point of no return I pulled the pink panties down the shaft of my cock and blew my load all over the mirror. What a fantastic JO, I am looking forward to the next time the MIL visits. If I could figure out a way to get her to jack me off with her panties that would be amazing.
