A few months back I posted a story about Les, a fat bloke in his late 50s who I'm fucking on the side, and his fetish for wearing my panties whilst he fucks me. About once a week I end up at Les' grotty flat when I've told my husband I'm out with the girls for a drink. Les and me always have sex there, which always involves him sniffing, wearing and spunking in my knickers. But he's got a really fat cock which makes me come which is more than I can say about my boring husband. Just last week Les arranged to take me for a drink and then back to his place. He told me that he wanted me to have sex with my husband that morning and have his spunk in my panties all day. I managed to get hubby to give me a quick fuck before work and he quickly shot his load up my hole. I put on a pair of black knickers as Les told me me. He said the spunk stains would show up better on the black crotch. After the pub, we ended up back at Les' place where, once undressed he demanded my panties. He sniffed the spunk stained gusset and his fat dick was at full stretch against his beer gut. I knew this leaking cock would soon be ploughing my cunt and filling my womb with his thick creamy sperm. Les called me a slag and got me to wank his cock whilst he sniffed my dirty panties. He then pushed the bloated head of his cock on my knicker gusset and with a deep grunt flooded the crotch with his own spunk. I worried that he might be satisfied and wouldn't shag me but within minutes he was stiff again and put on my soiled silky knickers. His dick poked out past the waistband and his arse and balls stretched the frilly panties to the limit. He then started to ride me, telling me I was a dirty slag and that he could feel all the spunk rubbing against his balls. He was grunting like a pig when he finally shot his cream up my cunt giving me an orgasm along the way. Later on the way home, I could feel all the semen in my panty gusset chafing against my pussy, which was dripping with Les'spunk. Back home I threw my dirty knickers on the bedroom floor, not bothered if my husband would find them.
