When writing about forced bisexuality, the sub isn't actually gay (yet). For him it will be far more degrading to perform those acts than it would be for a gay slave or a more experienced bi bitch, so explain in great detail why they're disgusted an feeling humiliated going bi, here's some ideas of what he may feel and think inside When cleaning a man's feet he'll be focused on the difference to womens: the rougher less cared for dry, calloused skin, the stronger and more abrasive aroma as they're sweatier, wjich combined with the bigfer size means there's more grime and sweat to be swallowed, the fact they have a stronger and more unpleasant taste, especially when likely washed less. This will all make the slave extremely humiliated to be worshipping a man's feet, doubly so if they're turned on by it despite these facts. This holds true for other acts too. With rimming, a man's ass will be hairier than a woman's, which will right off the bat cause embarrassment to the slave. There will also be more smell and taste to their sweatoer ass, more bitterness. There won't be the right pheromones to promote arousal as the slaves get when worshiping women. Men also have the potential to enjoy it much more than women too and causing another man this much pleasure with their tongue may degrade the slave further. Serving cock is a whole other story. If they get turned on by cock then they need to question their sexuality. Even if they arent turned on, they likely will be questioning their sexuality after submitting to cock. A man's balls smell of hormones and of sex; they are hairy and sweaty, super degrading for a straight man to have in his mouth. A cock will feel alien inside. Even if he's sucked a strapon before, it's nothing like the most intimate part of another man violating your mouth and throat, literally choking the life put of you, just to get him off. A cock is made to deal with two things; piss and cum, and³ the slave is very aware there's the assumption he'll be swallowing at least one of those disgusting liquids. Having another man's dna in their stomach is a thought that makes most straight men gag and this slut is expected to savour the taste? As it coats their tongue with its nasty, salty, bitterness and slowly slides its way down their throats, these slaves truly feel they're the lowest they can go. They do it to please their mistress and in turn get aroused from submitting for them (make sure you make it clear in your writing its consensual and they do enjoy being so degraded). Drinking piss is likely even worse. The man or the domme might suggest (demand) the slave take the cock in his ass. This makes him a slutty bottom, a receptacle just like a woman is and he's literally getting fucked for another man's pleasure. Firstly the pain is immense. He's being stretched open massively, often with inadequate or even non existent lube and a forced bi slave gets pounded and abused. Being bred seals your place as a pathetic sissy.
