Don't stop now!

In the darkened room, I could barely make out Elizabeth laying on top of me, let alone Li. I felt a hand on my dick, and Elizabeth lowered herself onto me. Her wet folds enveloped me as Elizabeth cupped one of her breasts and held it to my mouth. I sucked it roughly as she stifled a moan.

My eyes were adjusting to the darkness again, and I could now gaze into my girlfriend's lust-filled eyes as she rode me. I glanced over at the other bed. Only Li's dark hair and sheets—she must have fallen right to sleep. The added presence in the room amplified every lewd sound that our fucking made. My cock sliding into Elizabeth's soaked snatch, our thighs colliding, my partner's involuntary vocalizing, all made it seem impossible that we weren't noticed.

Elizabeth's incredible body pressed down on me. She was firmly in control, rotating her hips and whispering "I want you to cum in me," brought me right up to the edge. It was impossible to resist. I gave myself over to her. One more slam from her hips, one more thrust into her, and I exploded deep inside. She dropped to hug me as I spasmed inside her, her warmth everywhere. I started to apologize for finishing so quickly.

"Don't. Go get cleaned up and we can go again."

Thankfully, the girls had a jack-and-jill bathroom shared with their neighbor. I felt a little awkward crossing the foot of Li's bed with my erect penis on display, but luckily the adjoining door was closed, and I had privacy. It was easy enough to navigate by the nightlight, so I was able to see the light streaming in under the door I'd just closed. Fuck.

Li must have woken up and turned on the light. I found a towel and covered myself, trying to look casual. I cracked the door, expecting to see Elizabeth under covers and Li at her desk.

To my surprise, Elizabeth's bed was empty. They'd turned on the bedside lamp, so I could see that she was in bed with Li, still gloriously naked, and running her fingers through her roommate's shiny, dark hair. Li's black eyes were scanning Elizabeth's face, a mix of fear and hope. One hand had found Elizabeth's shoulder, but the other lay limp on the bed. Her pale skin beamed under a black tank top.

Elizabeth closed the distance between them. A cautious kiss, she pulled back to check Li's eyes for approval. Then she dove at her roommate, and their lips pressed together in total bliss. Elizabeth trailed kisses to Li's collarbone and back, then tenderly parted her partner's lips with her tongue and drew their kiss in deeper. Growing bolder, Elizabeth ran her palm over Li's small chest through the thin fabric. Li returned the favor, timidly reading her own free hand to Elizabeth's shapely breasts. I felt my erection grow as the two women explored each other, wondering what I ought to do next.
