My daughter-in-law and I are having an affair. It didn't start out as you'd typically imagine one would, but played off my newly-discovered fetish, of which she became a willing participant. It's interesting, in a very fun and stimulating way, both physically and mentally, to see how people's minds work. How people bring their deepest secrets and fantasies to the forefront with the right motivation. We nurtured each other's to the fullest, and continue to this day.
Since she's demanded complete discretion, from now on I'll simply refer to her as Gillian's sister. Gillian is the older of the two siblings, and while she's a nice enough person, she's not as interesting or attractive as my daughter-in-law. I was always fond of Gillian's sister since we initially met, and had spent more than a few moments over the years fantasizing about making love to her. While not quite an identical twin, I swear if she walked into Walmart wearing a black jumpsuit with bright green trim, more than a few people would ask "Danica" for her autograph. The resemblance is that close.
Gillian's sister stands about 5'-8", maybe 138 pounds with 34B breasts and 34-inch hips. How do I know this? Well, aside from the obvious, a couple of years ago, before our affair began, I was alone in her home when I went into the master bath and saw a beige bra hanging on the door knob, and her panties on the floor. Because she and her husband work, there are times when an adult needs to be at their house when their child comes home from school. On this particular day, I had grandchild duty.
Being the pervert that I am, which my daughter in-law will confirm, I just had to feel her bra and try to smell her fragrance, thrillingly bringing both cups to my face. It was cool and soft, with just the slightest hint of her scent. Next, I reached for her panties, laying atop some other clothes, and examined them. There was no obvious evidence they'd been worn or soiled, and I brought them to my nose as well. I had now joined the panty sniffer club. To my disappointment, there was no detectable fragrance, and was left only with the knowledge of them belonging to her. Despite this, I decided to rub them gently over my face, imagining how they felt caressing her ass and pussy lips. I'd satisfied my particular urge that day.
About a month later I found myself alone in her home once more, waiting for their child to arrive via the school bus. I immediately went to the bathroom once again where I noticed two panties, a red and a blue pair, again in a pile along with a similar bra as before. Again, I placed my nose in the cups and inhaled deeply, imagining her nipples hardening within those confines whenever she started thinking naughty thoughts. Next, I examined both sets of panties, never finding any objectionable evidence of wear. I brought both pair to my face and again inhaled, as well as running my tongue across the delicate material.
It was at this point I knew I had to have a souvenir, and debated which pair to take. Realizing she might notice one or the other missing at some point, I opted for a clean pair. Opening a dresser drawer I hit paydirt. All her clean panties lay before me. Many were quite sexy looking, a few were simply serviceably plain. When I discovered she had several pair of black panties, I chose the pair with the lace waistband, again rubbing them against my face to feel their silky smoothness.
I kept them in a secure location in my own bedroom for more than a week, taking them out when I felt the need to be as close to her as I could at that point. Because we would mildly flirt with and tease one another, I became emboldened over time and began plotting the right moment when I would suggest to her we should go further than mere words. Within a short period of time I began using those sweet panties while masturbating, wrapping them gently around my cock and softly stroking up and down. I was pleasantly surprised how smooth they were as they caressed my head and shaft, and didn't chafe at all. Each time, imagining we were together, I'd cum bucket loads. And of course wash them after each session.
Then one Saturday afternoon my wife and I held a family get together with about eighteen others. Gillian's sister and I were talking, out of earshot of the others, when I finally made my move, verbally.
"We should get together and make love sometime soon," I began.
"Oh really? And why would I want to do that?" came the reply.
"Because we'd both enjoy it, and I'd make sure you'd enjoy it more," I said.
"What makes you think I don't enjoy the sex I'm having now?"
"You may very well be, but something tells me it may not enough for you."
"That's a pretty bold statement," she shot back immediately. "What ever gave you insight into my sex life?"
"I hear things, sense things. I know you had a very active sex life before you were married. Which is not to say you were promiscuous by any means, just that you were enjoying yourself more back then."
"Well, thank you for that. I think."
"Seriously, I think we're both attracted to each other. We always flirt, and you could cut the innuendo with a knife. I want to, and I believe you think about it as well. There could be any number of reasons why, but why overthink it? It'll be good for the both of us. Besides, like the song goes, 'I'm not talking 'bout movin' in."
"Wow, sounds like you've given this a lot of thought. And I don't know that song."
"Well, I'm a little older than you so our musical tastes might be somewhat different. And yes I have given this a lot of thought, and have already taken it to the next level."
"Oh yeah, how's that?" she asked.
"I have a pair of your panties."
Turning towards me she responds with, "You have what?"
"A pair of your panties."
"No way. Which ones? Where did you get them? When did you get them?"
"Black, size 34 waist. Have a lace waistband, and are very soft. One of the best gifts I ever gave myself. Remember, I'm sometimes there when your son comes home from school. I got there early one day."
"Fucking perv. What have you done with them, and how has your wife not found them?"
"I keep them in a safe place, and retrieve them when I need to use them."
"Use them? Use them for what?"
"I use them when I jerk off."
