This snapped me out of my daze, and I yanked my hand away and turned the lights on. I looked down to see you in front of me, face inches from my body, staring at the bulge in my sweatpants. Before I could step back, you reached up to my waistband and pulled my pants down. I'd been hard since you led me out of the theatre hand in hand. You stroked my cock lightly, appraising it for a few seconds, before looking up at me, still grinning.
"You should turn the lights off or they'll see it from under the door."
My hand still hadn't left the light switch, and seemingly on its own, flipped it back to off. We were in darkness again.
"Hannah, we can't do--" I didn't finish the sentence as I felt your mouth around me. Between your hands and your mouth, I couldn't think of words. I knew that any more protestations would be lies. I had turned off the lights myself, after all, so there was no chance of feigning innocence. All I could do was gasp as your lips slid down over me, taking me into your mouth, your tongue playing along my length. My knees buckled, and I steadied myself on the wall with one hand. With my other, I locked the door from the inside. I was making the choice to go ahead.
You weren't going slowly, or taking your time and trying to eke some romance out of the situation. This was not a tryst, or a "moment." This was a blowjob from my friend in a dark room, with my girlfriend somewhere else in the building. It was dirty, and wrong, and we both loved it. I heard and felt you moan around me, and my hand went back to your head, running my fingers through your hair; following, not leading. You increased your pace and intensity, not wanting to get caught by being late back to rehearsal, and my hand instinctively grasped a handful of your hair.
You moaned a little louder than I thought safe, pulled my cock out of your mouth, put your hand over mine and closed it tighter on your hair, and breathed, "Yes! Pull my hair. Be fucking rough. Fuck my mouth, please! Hurry up, though; Laura might come looking for you." Then you took me back into your mouth, forcing yourself down my length.
I couldn't take any more of my brain's stalling or delaying. I tightened my grip on your hair, pulling your head back. You laughed, again louder than I thought safe. I leaned down to you in the dark of the office and whispered, "You're going to get us caught. Stay quiet." You laughed again, and said, "Make me." That did it. I stood back up, pulled your hair even tighter, and pushed you several inches until your back was against the door. You'd gone from kneeling to crouching, forced back between the door and my lower body. I placed the head of my cock at your lips and they immediately opened. I slid into your mouth and leaned forward, resting my forehead on the door, and grabbed the sides of your head with both my hands. You wanted it rough? I was going to give it to you rough. Your hands went around to my back and grabbed my ass, pulling me back you into every time I pulled out to thrust again. This wasn't just me fucking your mouth, it was you fucking me with your mouth.
I pulled back to catch my breath, and you took the opportunity to grab the base of my cock with one hand and close your lips around the head, sucking harder than I'd thought possible. You sucked me into your mouth again and slid me out, stroking me fast with your hand. You growled, "Cum in my mouth," and started stroking me harder, the head of my cock slapping against your lips and tongue as you kept me just barely inside your mouth. All at once, I pulled your head down, forcing my length into your throat again before coming hard. You swallowed as I came, never stopping with your tongue or your hand, gently slowing as I finished.
I finally started breathing again as you sat down onto the floor, giggling, and gave the head of my dick one last kiss and flick of your tongue, making me twitch.
We both froze as we heard the door handle rattle. "No, this one's locked," we heard Laura say in the hallway. She was only two inches away from us, just on the other side of the locked door, and here we were, hiding out in a small, dark office with my cock still in your hand. "She's got to be somewhere around here. I could've sworn I heard her," she said as we heard the sounds of two people continue down the hallway.
We kept the lights off as we straightened ourselves out and waited for 30 seconds before I opened the door and looked out into the hallway. The coast was clear. I gestured to you that it was safe, and we quickly went in separate directions, to eventually both make it back to the theatre, hopefully with nobody the wiser.
