Sam's knee gives out, requiring the removal of his pants for a close-up inspection

Barely have you reached the top and confirmed that the hallway is clear than you hear a cry behind you. Whirling you see the dresser not moving and Sam sitting on a stair, clutching his knee.

"Are you okay? Did your knee give out?" you ask, clattering down the stairs as fast as you dare in the four-inch heels.

"I, ah, might've done it some damage," he grunts.

"Is it... dislocated?" you ask, staring at his denim clad leg like you have x-ray vision.

Sam shakes his head. "I don't think so," he says, and starts unbuckling his belt.

"Hey! What are you doing?"

"Gotta see the damage," he says, unzipping and popping open his jeans.

"B-but..." you stammer, staring wide-eyed as you realize he's been going commando under his jeans, his manhood visible and thick against the dark mass of pubic hair.

"I-I'm gonna push myself up. Can you pull the jeans down?" he asks.

"Wh-what? Me? Why not Bill?"

"Don't look at me. I'm not going near that," Bill snorts, waving at Sam's exposed dick. "Besides, my back's hurting something fierce right now. I don't want to bend over."

"Uh... Uh..." you stare down at the injured man - or more precisely at his semi-hard dick, which looks not at all shabby, even compared to Jacob's. "I, uh, I guess," you stammer.

Trying to convince your self that there's nothing wrong with pulling off a non-boyfriend's pants, resulting in said non-boyfriend being naked from the waist down, you flutter your hands as you try to decide where to grab.

"Okay, I'm pushing up. I've gotta try to keep the knee immobilized until I see it," Sam says, and gingerly lifts himself up.

Gulping as his action seems to offer his groin to you, your fingers dip into the fly to pull it apart, inadvertantly brushing both pubic hair and dick. It stirs and you pull back, stammering, "S-sorry."

Sam grunts, but holds still, and you reach forward again, opting to try grabbing at the bottom of the zipper. Unfotunately your fingers slip in and rub against his hairy testicles. Again your hand retreats and you give a stuttering aplogy.

"C'mon Jenny, you've seen tons of naked men before, right? What's one more?" Bill asks, and you nod, reaching forward once more.

Your hands grip each side of the zipper and you feel your hands slide against the smooth soft skin of his dick. It jerks a little at your touch and you freeze, staring down at it as if it was actually a snake.

Then, of course, Tom comes back with his filthy mind and exclaims, "Shit, she's giving out blowjobs already? I thought we were maybe ten minutes from that."

All three of you glare at him and he backpedals. "Sorry. Handjobs?"

"Sam's knee gave out. She's helping inspect the damage."

Tom leans forward. "Looks swollen," he smirks, and you glare and flush at the same time.

"That's not his... that's...." you shut your mouth, too flustered to continue, and resolutely turn back to the jeans in front of you, only to see that Tom had spoken truly.

With your hands both touching his dick and you moving his dick has come to life, becoming ever harder.

"Ah..."

"Sorry Jen," Sam says, trying hard for a sincere expression. "You know how it is with guys. The touch of a beautiful woman makes the trouser snake react on its own. Just, uh, ignore it and pull."

"Right. Pull. Harder," Tom mutters, no doubt making hand gestures and sending even more blood rushing to your face. It occurs to you how embarrassing it would be to faint face-first into the pants of a man, while another part of you wonders if you should try it.
