I'm planning to write a story about two men's first time in bed with each other, and I want them to run into some trouble with lube.
The characters have had sex with each other before, but not penetrative sex. That's what they want to do this time, but half-way into it they realise that they forgot to buy lube. They don't want to scrap their plans, so they decide to raid the house and find a substitute, most likely in the kitchen.
I need them to find something that gets the job done but causes some minor discomfort for the bottom the following morning. The guy on top will wear a condom, so his exposure to the stuff is lesser. It would be especially great if the lube was something that would be a little difficult to get properly out of the bottom so that they have to use an enema kit to clean him out.
I have searched for "what not to use as lubricant", "worst lubricant ever" and simply "anal lubricant", but I keep finding discussions about what people should use. The discussions about what people shouldn't use don't really give me the information I need. The problems I see listed are mostly just that certain types of lube will weaken the condom.
Based on my searches, I feel like my best bet would be olive oil, but if there's anything better, I'd love to know. Thanks in advance!
