I reserved a private study room for one, or so I thought… [M/f]

I walked into my dorm room, drained from today’s shift, but also determined to get some last minute cramming in for my exam the next day. I immediately dreaded what I saw, my roommate and his girlfriend cuddling and being generally obnoxious with their affection. So entranced with each other, they didn’t even notice that I walked in. I sat down at my desk and tried studying for a little bit, but their air of lust in the room became too thick to focus. I decided to reserve a study room in the library via my university’s app. I quickly got up and started to pack up my laptop and such when I looked down and realized that I was getting aroused from my roommate’s shenanigans. I did a little waistband tuck maneuver and made my way to the library with lewd thought swimming in my head. How was I ever going to get anything done with my member betraying me like this? I made my way through the entrance and took the stairs down to the lowest, quietest level to my reserved room. To my surprise, I was met with short brunette girl facing away from me towards the room’s chalkboard, scribbling some arithmetic next to a series of detailed graphs. My eyes drifted from the chalkboard to this unexpected visitor. She wore a simple tank top with a black skirt that barely covered her ass. She turned around as I opened the door further and I noticed her small, but well shaped breasts, I could tell she was wearing no bra. “Excuse me?” I realized the lewdness of my gaze and immediately brought my eyes up, cheeks flush. “I…uh…” Fumbling with my phone to show her the reservation “reserved this study room”. She skeptically glanced at my phone “I’m right in the middle of something right now, your eyes told me that you wouldn’t mind sharing” she winked and turned back to the chalkboard. I unpacked my bag and got to work, but the onslaught on my focus continued. Every few moments, she would bend down towards her laptop to make adjustments and I could just see the bottom of her ass, it was driving me wild. I kept working, but my mind was elsewhere. I swear she knew what she was doing. My suspicions were all but confirmed when she made an exaggerated lowering to her laptop, back arched, I could just make out the black and white lace of her panties. “Having trouble focusing back there?” She said still tapping away diligently at her laptop. I was at  a loss for words and awkwardly kept working in silence. Things calmed down and I started to really get some work done, when I felt the chair right next to mine move, and the mysterious girl sat down next to me. She give me a wry smile and began working. My cock twitched as her thigh rubbed against mine during the study session, and I began to pitch a massive tent. She suddenly closes her laptop and looks down at my poorly hidden erection. Her hand closes around my cock over my pants as she leans in close to my ear. “I can tell I’ve made it hard to focus, let me make it up to you” each word spoken her tongue caressing my earlobe. “I’m not sure if this is the right time-” silenced by her confidently reaching into my pants and grabbing my cock. “Are you sure about that? He doesn’t seem to agree” she nodded towards my cock, now bear in the open, pre-cum seeping out. Without warning she spun my chair around and seated herself on my lap. I finally gave in and grasped her perky tits. She let out a quiet moan and continued grinding on me. I decided to take charge and moved my hand slowly from her knee to her thigh and finally to the waistline of her panties, I pushed her forward and pulled them down just enough to make my way inside her through her skirt. We both gasped in pleasure as I entered and she sat back taking all of me in. She continued grinding on me and working her way up and down my shaft. “I’m getting close” “me too” she spun herself around to face me, we locked eyes and met mouths. Feeling each other’s tongues while continuing to rock in unison, I began to climax. Letting out a low groan I released everything inside of her. I felt her quiver as I finished and we lay there in each other’s arms for a few minutes. In silence, we both got up as if nothing happened, and got back to our studies. After that whole escapade, I swear that’s the clearest my head has ever been while studying.
