These guys are straight but they had messed with the wrong mistress. Mistress Gaia was not going to accept any nonsense from them and she had to punish them to make sure they never pissed her off again. And she did it by forcing them to be bi. She had them lick each other, kiss and even suck each other's dick. She warned them that if they messed with her again, she would make them fuck each other's ass.
