Nick prepared himself. He was going on a date and he wanted to look attractive. Casually so, but that demanded a bit of work nonetheless. It also greatly amused him that his brother Jeff was going along for the ride. Jeff who was now forced to be happy being his armpits. Actually, Nick made a note to reward Jeff through his date. If he was a good armpit. The poor guy would require something nice. As for Jeff, he was beyond happy. A date! He was going on a date! Hopefully he'd see sex and some action! Oh! But that meant his mission as an armpit was important! He must enthral the girl's unconscious by bombarding her own unconscious receptors with chemical messages about how Nick was incredible and powerful and virile to have babies with and so that the babies would resemble Nick. He would do his best to make that girl understand how good it would be for her and Nick to have a fruitful intercourse.
Quite a few hours later, when Nick returned from his date, he was exhausted. The sex had been great, the food okay but if that girl was fun to have sex with, they didn’t really share any interests. Oh, well. At least the sex had felt good. He then thought again about Jeff. He'd barely paid him a thought during the intercourse. Only when he'd ask the girl to sniff his pits and scratch them. He then thought about what to do with his brother next. He had several ideas about what to transform him into next. Something that would make him less miserable and happier. He'd have to consider all the possibilities and come to a decision as to which one was best. He fell asleep, snoring, after crashing on his bed.
As for Jeff, he was not exactly happy. Sure, the girl sniffing him and scratching him had been delightful. If he'd been human still, it would have been enough to give him an erection. That and seeing the girl naked and getting on with his brother like in a porn movie. But that had been all. He had spread his pheromones as must as he could, making his brother's sweat be put to good use. And that seemed to be working, considering the intensity of the intercourse. But then, Nick had put a condom on. Jeff could've yelled in frustration. No! All that work for nothing! He was furious with Nick for that. Idiot! Did he even have the faintest idea of what as at stake? Of what he had to do all day while was stupidly oblivious? Nick had to spread his genes now! It would be much harder to do so in his old age. Unless he was super rich, which would be unlikely. The idea of being the armpit of an old man instead of a young one wasn't relishing but if he had not reproduced... That would be the worst! Jeff fell asleep, exhausted by the night's love-making. He'd find a way to communicate his worries to his master tomorrow. One way or another. Or he'd have to bear the brunt of the mission while his owner acted like an idiot. Typical. And he'd have to deal with Nick's sweat as they both slept. He wondered how other armpits felt about their situation. However, Jeff was not aware of Nick's plans for him.
