Such manly smells

You took delight in watching his horror, knowing that he would soon be begging to join in. Your mind whirred with possibilities of how to induct Nathan into your harem when you caught a whiff. Throughout your monstrous antics, you failed to notice that Dad and Hank had worked up a sweat in their short time outside. The smell of their bodies was musky, with the semen that was there earlier just noticeable. It was perfect.

Nathan had failed to budge, watching his relatives engage lustfully. He was horrified by the sight, though, like a car accident, couldn't look away.

"Quite a sight, aye?" you ask, eyeing Nathan rather than the show.

"What the fuck is wrong with you all?" he asked, finally able to form a reaction.

"We're just showing each other love." you say, acting like this is all normal, "I think the men of our family should do more of this sort of thing."

"It's sick." He yelled, taking a step back.

"Take a sniff though." you tell him, knowing you have to get him before he runs away, "What does it smell like?"

Nathan took a whiff, face screwing up.

"It smells like a gym locker room." he says, "It's rank."

"It's hot." you correct.

"Fuck off!"

"No, Nathan," you say, staring him down, "it's hot. The smell is hot and horny. That musk, the sweat, the cum, the raging pheromones. It's so fucking sexy and erotic."

Nathan took a step forward, breathing in the air. His shorts bounced a little as the smells invaded his nostrils.

"This... But... What?" he stammered, growing aroused by what he could smell.

"It's addicting, isn't it?" you goad, "That smell. You need it. Your cock is growing so hard because of it. All that muskiness is just an aphrodisiac straight to your dick."

Nathan moaned, palming his dick through his shorts. He had wandered towards his lusty relatives. His eyes were closed, whatever levelling he was doing in his brain to justify his new kink. He needs more corruption.

"Open your eyes Nathan." you order, forcing him to stare at your Dad, Mitchell and Hank, "This smell isn't one you can get just by going to the gym, no. This is pure, familial pheromones. The only way to get this stink is gay, incestuous fucking. Working up a sweat as you fuck or spilling your seed as you get plowed is how you're going to get this smell again."

Nathan had fished his dick out, wanking as he had his nose right up against his Dad's pit. His eyes showed some resistance, but his furious jerking was dimming that light. You leant in, whispering in his ear.

"Admit it Nathan. You're a gay slut for your family. Cock, ass, mouth, you'll use anything just to work up an incestuous sweat and get a whiff of man. Say it."

"Ungh... I'm..." he moaned.

"Say it."

"I'm..."

"Say it."

"Ohh... Gay..."

"Say it Nathan!"

"I'm a gay, incestuous slut!" he screamed, exploding in his hand.

You smiled as you watched your cousin begin to lick up his own semen. No longer was there any shock or disgust, just pure, lusty bliss.
