Before you plan anything, an unexpected opportunity falls into your lap

You barely slept.

Carrie stole the comforter sometime after 2 AM, left you on the sheet in boxers with a cock that wouldn't go soft. Every time you closed your eyes you heard her voice. Means no seeing me naked either. You kept getting hard; your cock didn't give a shit what you wanted it to do.

Sometime before dawn you heard David come in and crash onto the couch in the living room.

When it started getting light out Carrie was already awake beside you, staring at the ceiling.

"David's on the couch naked," she said. Flat. "I got up to pee around five and he was just lying there with his dick out."

Neither of you said anything for a while.

Then she rolled onto her side and looked at you, hair mashed flat on one side, eyes puffy.

"I think I should go out there and sniff his balls," she said.

You stared at her.

"Put my nose right up against his sack and breathe his nasty shit in for an hour straight before work. Really get the stink of his nuts up in my sinuses so I can smell his sweaty balls all day while I'm teaching yoga."

"Do it," you said.

She blinked.

"You sure?"

"You're the one who said anything."

"...you sure you won't regret it?"

"Go sniff his balls, Carrie."

She stared at you for a few seconds, waiting for you to back down.

"Fine." She threw the comforter off, swung out of bed in a tank top and underwear, yanked a pair of black yoga pants off the dresser, and pulled them on without looking at you or fixing her hair.

You followed her down the hallway. You could see the shape of her ass in those yoga pants the whole way.

She stopped where the hallway opened into the living room.

David was on the couch, sprawled out on his back, naked.

Fourteen months living with this guy and you'd never seen him without those baggy-ass shirts and oversized basketball shorts. He was bigger than you expected. Had a gut on him but the frame under it was wide, hairy, thick. You stared at what was between his legs.

His cock was lying on his left thigh and it was longer soft than yours was hard. That's what you noticed first. Nine inches at least, uncut, foreskin bunched over the head. It just sat there, heavy.

Wiry black hair so dense covered his balls you couldn't see skin, spreading from his crotch into a bush that climbed his belly and crept down his thighs. His sack hung low and heavy against the couch cushion.

You stepped past the coffee table, stopped a few feet from the couch.

Carrie stood at the foot of the couch staring down at it. Then she lowered herself to her knees between David's spread thighs, slow. You could see the curve of her lower back.

She leaned forward past his cock, down to the hairy sack hanging between his legs, and stopped with her nose maybe an inch from his balls.

She inhaled.

Long, deep, nostrils flared. Held it three or four seconds, then blew out through her mouth and sucked in again harder.

Carrie kept her distance at first. Eyes closed, breathing slow. Every few breaths she'd pause before she went back to it.

She had been at it maybe ten minutes, twelve, when things started changing. Her hands came up off the floor and settled on David's inner thighs. She wasn't hovering anymore; her head had dropped closer, elbows bent, her nose directly touching the matted hair on his sack. She was settling in.

Then at maybe twenty minutes David's cock twitched. Over the minute you watched it fill up, the shaft thickening, lifting off his thigh, the foreskin stretching as his dick swelled underneath.

When it was fully hard it was at least eleven inches, way thicker than yours. It curved leftward, veins standing out dark against the shaft. The foreskin had peeled back, bunched up behind the head.

The head was ugly, dark purple and blunt, wider than the shaft. Under the foreskin where it had peeled back there was smegma caked into the folds, yellowish and waxy, and mixed in with old dried cum.

Your cock went soft. Then a few seconds later it twitched again and you wanted to throw up.

What the fuck am I doing.

The second half-hour blurred. It was more of the same but worse.

At some point her nose was buried in the wiry black hair on his balls, her hands bracing on David's inner thighs, sucking in these long, greedy inhales.

That's my girlfriend on her knees with her nose buried in another man's balls.

Your knees ached, standing.

Around forty-five minutes she pushed her face all the way in, just buried herself between his thighs. Deep **** huffs through her nose now, louder than before, like she was trying to suck his stench all the way down into her lungs.

David's cock leaked. Pre-cum ran down the shaft in a thick line, catching in the smegma caked under his foreskin.

He slept through it.

The alarm on Carrie's phone went off at 7:47.

She pulled her face out of David's crotch and you saw her for the first time in an hour. Flushed, mouth open, hair stuck to her face, kneeling there blinking like she'd forgotten where she was. She grabbed the arm of the couch and pulled herself up.

"Shit, I'm late," she said. Cleared her throat. "I'm late, I gotta—"

She turned toward you. That's when you saw David's pubic hairs all over her mouth. Dark, coarse, three or four stuck to her lower lip, two more between her front teeth, one at the corner of her mouth trailing toward her chin, one on her upper lip pressed flat. Another man's crotch hair jammed between her teeth and she was about to walk out the door.

You almost said something.

She walked past you, grabbed her gym bag and keys, jammed her feet into sneakers. You could smell David's balls on her breath.

"Bye babe, we'll continue this later," she said at the door with a quick smile and wink, nostrils still flaring.

You went to the bedroom and sat on the bed.

Carrie was driving to work right now. She was going to walk into the studio, set up her mat, stand in front of a room full of people and teach a class. With David's pubic hair between her teeth.

That's not... nothing's going to happen. Right?
