I did this a few times when my wife and i used to stay at her mums. My wife had a sister who was 18 and she was pretty and sexy back then. I used to get a pair of her panties from the draw and sniff them and wank with them wrapped round my cock. Still kinda turns me on thinking about it. I did cum on them once or twice and slipped them into the washing basket. Very naughty but quite hot.
When away from home working I always had panties to masturbate in. My wife provided for me. A great wife.
During my first marriage I used to wear my wife's corset, panties, stockings, and garter while jerking off. I'd walk around the house swinging my cock back and forth against my thighs before stroking myself in just about every room of the house before ending up in the bedroom, opened the corset and shot my cum all over my stomach, chest, and face and then licked it all up.
I have had a girdle fetish ever since my mother spanked me over her knees while she was in her girdle and stockings. The sensations were absolutely amazing. She noticed how aroused I was getting and never did it again, sadly. As such, I have worn pantygirdles, girdles, panties, stockings etc as sexual stimulants. Pantyhose works as well with nice panties. My wife does know and has indulged me. Great wife.
Same experience as myself in the 50s seeing my mum getting dressed in her bra, panties and girdle with suspenders and putting her nylons on , had a fetish for panties, girdles and stockings ever since, I visit my nephew regularly to help with gardening ect, now I'm retired, a few months ago his wife caught me with her panties in my hand holding them on my face, she didn't say anything just smiled, she now leaves her panties and bra's for me to take home and even tells me when she gets back from work that's she's just changed her clothes and there's something on her bed for me , she sometimes leaves them in a bag on my car seat before I go home, on Christmas day we exchanged presents and she wispered there's a special presents for you, when I got home she had wrapped her bra and panties in Christmas paper for me, I always returned them washed and folded, now 73 and single this is wonderful for me and so erotic.
I love to smell the used one, particularly if there are stained with the golden water and her ass. I have been a panties sniffer since I was a kid. I used to sniff my mom's and my sister's panties, and whenever I had a chance to grab some panties from my relatives or friends. I had a lot of chances to get my wife's sister's panties. She lived on the second floor for at least 10 years with us, so, when nobody was at home I went upstairs to check what I could find. My wife did not know anything about it, but I think her sister understood that sometimes has been checked her intimates by someone who could be me.
