Not too long ago I found out a friend of mine was really into underwear. I was making fun of him about it and he admitted that he had once sniffed a pair of my wife's worn knickers from the hamper. Initially I was annoyed, but the more I thought about it the more the idea of him getting horny from her scent the more naughty and arousing I found it.

I invited him round a couple of days later while she was working, and after about an hour I got up and fetched a pair of her underwear from her drawer and threw them to him, and asked him what he thought. He said they were nice and changed the subject, but obviously I wasn't going to let it end there, do i then went and fetched the thong she had worn the previous day and threw that to him. I asked if he wanted to sniff them. He declined. I told him that they had spent the day against her pussy and ass, and would be packed full of her scent before asking again if he wanted to sniff them. Again he said no, but there was much less conviction in his voice. I told him that I thought he SHOULD smell them, and without much more of an argument he did. Slowly at first, but quickly devolving into long deep inhales of the crotch of her panties. Once was sniffing away passionately I suggested he should wank into the other pair. Again he was reluctant, but I told him my naughty plan. He cums into my wife's knickers, and we put them back in her underwear drawer. Then in a day or two she'd put them on and his cum would be up against her. That was all it took before he took out his cock and started tugging, and it didn't take long before he blew his load on the gusset and ass of her 'clean' underwear. I put them back in her drawer as I had said, and he went on his merry way.

A couple of days after, as we had hoped, she put on the cum filled panties. I made sure to let him know she was wearing them, and he made sure to let me know that he'd got off to the idea of his cum next to her pussy.

Since then I've let him play with my wife's underwear a few times. Sometimes cumming in them, sometimes sniffing them. Any time she gets new pairs I'll send him a picture of them, and give him updates and pictures of her underwear drawer. I've even sold him a pair of used panties so he could take them home with him.
