Seeing Justine in a New Light

I slide my finger inside myself again, unable to stop now that Justine and this man she just met are fucking right in front of me.

He thrusts in and out of her, slowly at first, his speed increasing as Justine's moans grow deeper. Each thrust lifts Justine off the bed, until the stranger has a hand wrapped around each of her thighs, lifting her legs off the bed as he buries his cock deeper and deeper inside her.

"Damn, I love your pussy," he says.

Justine can only moan in response, and my own breath quickens as I realize there's a tension growing inside of me, like a growing balloon about to pop. I want more, and I pump my finger inside myself faster and faster, keeping time with the stranger's deep thrusts inside my roommate.

At last, the stranger calls out that he's coming. He pulls out of Justine, dropping her legs back to the bed and shoots a stream of come across her lower back. As I see his come hit her skin, the tension growing within me erupts, and I begin to convulse, an orgasm wracking my body. I stifle a scream as I, too, come.

With their adventure over, the stranger excuses himself to use the bathroom. While he washes up, Justine gathers her clothes from the floor and dresses. I think she casts a glance my way, but I quickly roll over and stare at the wall, embarrassed and disbelieving that I just watched all that I did.

"That was fun," he says, re-emerging from the bathroom.

"It was," she says.

"Maybe we can do this again?"

"That's be nice," she says. Justine leaves to escort him out of the house, but I'm asleep before she returns, spent from an evening I never expected.

When I wake up the next morning, I can't believe what happened the night before. I can only pray Justine didn't notice that I was awake, or, um, enjoying myself. My nerves are shot as I roll over to look at Justine's bed across from mine. I breathe a sigh of relief when I see that it's empty.

"I'm not used to you being the sleepy head," Justine says. I sit up in bed as she comes through the bathroom door in a robe with her hair wrapped in a towel.

"Well, you know," I say. "Those Lit papers don't write themselves."

"Yeah, I guess you're right." Justine bends over to take the towel from her head before sitting down at the vanity and combing her hair. "We missed you last night."

"Was it fun?"

"It was," she says. "We had a good time."

"Did I miss anything?" I say, trying my best to act like nothing was out of the ordinary the night before.

"Not really," she says. "Just another night out on the town. I'm sure you'll join us one day."

"Next time," I say.

"Next time," she says. Justine grabs her blow dryer and makeup bag to head back to the bathroom.

She stops at the door. "Just so you know, I'm glad," she says.

"Glad about what?" I say.

"I'm glad you ended up having some fun last night after all," she says with a sly smile.

My face burns with embarrassment as she turns to leave.
