Masturbating With Mother-in-Law's Panties
I had gone for a run earlier on the second day of our stay, so when they left for the beach I stayed behind at her place, telling them I'd maybe have a nap. The walls in her condo are paper thin, so there'd been zero chance for any action with the wife, so I was a little frustrated with unreleased desire.
They left and I went to the bedroom. Me and the wife were staying in her room, as it was the only double bed in the house, and MIL slept in the guest room with the kids. I was laying there, feeling my cock stiffen in my shorts, balls throbbing with built up cum.
So I started to stroke myself, imagining my wife's full ass in the skimpy red panties she'd worn the day before. Somehow the thought of my MIL in lingerie popped into my head.
She's a little taller than my wife, maybe five foot six and slim. She's always been a bit of a prude, not showing skin and usually wearing slightly baggy clothing, so I had always wondered what she looks like under them.. Whether her breasts are similar to my wife's and if her pubes have started greying.
So I stood up and opened her closet. Her clothes, neatly folded on the shelves filled the entire room, and I soon found her unmentionables in a box on the lower shelf. As I had guessed, her taste in underwear was conservative. No lace, just basic cotton panties and only in black or white.
I don't know why, but I was incredibly aroused. My cock was throbbing and strands of precum dangled from the tip. With shaking hands I caressed my wife's mother's panties, feeling the soft fabric, especially focusing on the double layer at the crotch. For some reason the idea of knowing her mature vulva had rubbed against those specific places aroused me like crazy.
I took out the next box, containing her bra. Same style, very conservative, for use, not to turn on a man and certainly not to push anything up. No padding. I dug out the size tag on one pair, it said 34D, so she was bustier than her 34B daughter. I hadn't known she hid that much under her clothes.
I was so turned on I couldn't touch myself.
I took out her panties, one by one, rubbing the head of my cock on the crotch of each pair, smearing my precum in them. I felt like that way I was claiming her unaware pussy with my juices
I took one of her bra and wrapped them around my throbbing shaft, reaching my climax with two strokes. I let my cum flow into the cup and them spread it all over the fabric rubbing it in.
I've never looked at her the same afterwards.
