Input: Text: i read a post on reddit recently about a guy who fucked a jar of peanut butter and i thought about how awesome that would feel.

so earlier today when my housemates were all out and i had a bit of me time, i decided i'd try it out. i figured i'd just throw it away when i'm done and buy a new jar, no harm done. unfortunately we didn't have any peanut butter in the house, but at the back of the cupboard i did find an old jar of hotdog relish that hadn't been used in about 9 months. i seem to recall it tasting pretty disgusting, but the chunky texture seemed perfect for my activities.

little did i realise that this particular brand of hotdog relish contains mustard, and about 10 seconds into the activity my member started to feel a bit hot, and about 15 seconds in i was running to the cold tap because it felt like my cock had been stung by a swarm of angry japanese wasps.
