I have a gorgeous boyfriend, except when we have conversations about sex. We often end up in one of two states, agreeing with each other and promptly carrying out the task at hand, or violently disagreeing with each other. The last one was in between, a very different outcome for us both.

It was on the topic of exhibitionism and voyeurism. I quite like it, and would definitely give it a go, but Matt was more ambivalent about it. He couldn’t really see the point, so I tried to explain about the uncertainty of the whole thing, how it would feel. Whether someone was watching and whether you knew they were or not. I tried to explain the excitement of being in a position of vulnerability and getting turned on by it. I told him that I would love stealing a moment of sexual release somewhere that it shouldn’t be done.

It took me two hours of getting nowhere to finally give up and acknowledge that we were not going to test this one out. Not in the immediate future at least, and so, we eventually started talking about oral sex and I found myself sucking his cock before he fell sound asleep. Obviously all this exhibitionism talk had worn him out.

We never discussed it any further and I thought that was the end of it.

Until I got a phone call from Matt, in the middle of the afternoon, while at work. He never phones me at work, but I was so excited to be able to talk to him, I answered immediately.

The conversation was normal up to the point where I asked him what he was doing.

“Watching porn on my tablet,” replied Matt.

“Why am I not surprised,” I retorted, “and why aren’t you at work. Don’t tell me you are at work?”

“No, I’m not at work.”

“That is such a relief.”

“So, do you want to watch it too? It could bring you some relief as well.”

I found that a strange thing for him to say, to be honest. How on Earth could I watch his porn? I quickly started to look around me to make sure he wasn’t in the office. I know he couldn’t have been, security would never have let him in.

“I’m actually in the library.”

“The what?” I asked, shocked.

The Library was opposite the office block where I work. My window looked out onto the second floor of the library, and I often watched people reading books or just relaxing and watching other people wander by on the streets below.

I had a very good view of the library. I cannot read the words on the books, but I can see everything people do, like adjust themselves while reading, breast feed their babies and couples having a quick grope in the aisles. All the people in there think that being on the second floor excludes them from being watched, but it doesn’t.

I suddenly find myself turning to look towards the library. First I scan the downstairs, then the upstairs. I see Matt in the corner at the back of the library close to the window but a few feet back from the edge. He is sitting facing the table with the tablet on top of it.

I couldn’t help but smile, until he moved the tablet to face me.

I couldn’t see anything dirty on it; to be honest it was a little too far away. I could see shapes and colours but that was it. But for some reason I became acutely embarrassed. I wondered whether the other people in the office could see him as well.

Before I had time to speak to him again, Matt told me that he had to put the phone down.

Just before the line went dead I blurted out the words, “Why?” I immediately looked across to the library.

I saw Matt fumble with his trousers and then I saw him pull his cock out.

At that point I was dumbstruck, my eyes were glued to the library and I couldn’t move. Talk about being stuck in the headlights of an oncoming car. I let out an involuntary gasp, causing Brian, my co-worker facing me to ask if I was alright. I just nodded. Fortunately he was facing me and not the library.

When I looked back at the library, Matt was in full flow. His tablet was on the table in front of him and he was jerking himself off under the table. I glanced around me to make sure no one was watching me and I started to watch his efforts in earnest. He did have a nice cock, even from this distance.

I had to stifle some giggles at the point of him sticking his tongue out and licking his upper lip, but I watched him handle his cock like a pro. I start to wonder how far he would go as I watched his cock stiffen and become hard.

To be honest, I really couldn’t believe he was doing this, not after the conversation we had a few days ago. But there he was; Matt, with his pink todger, poking out of his blue jeans, in the library. It reminded me of the game, Cluedo.

As I smiled at him, I suddenly became aware of other people that have a view onto the library. My mind was awash trying to remember where they all sat and what time of day it was. Jenny sat a few seats back, but she’s wasn’t in today. I let out a relived sigh as she would have been in a prime position. Brian in front of me is concentrating on his document and facing slightly inwards from the window and then there’s Melanie. Melanie is a few tables behind me and looking down the street straight into corner of the library where Matt is sitting.

‘Fuck,’ I think to myself, what if she sees him? What if she knows who he is?

I breathe the silent words, “I’m fucked” into my PC in front of me.

I pick up the phone and ring Matt. I watch as his mind registers that his phone is ringing and I see him pick it up with his spare hand. At that point in time I wished he would have used the hand he was wanking with, letting his cock naturally subside.

“You have to stop, put it away,” I told him.

I know I was a killjoy, but this was my job that he was risking; in a cute sort of way.

I couldn’t believe it when Matt just smiled and cut me off.

I was transfixed to my seat, I opened up Notepad and started tapping on the keys in front of me so that no one would become suspicious that I wasn’t doing anything. If they were to look over my shoulder then they would be amazed at what language I was writing in. So would I.

At some point through the proceedings I started to become aroused. I’m not sure when it started but my panties started to become wet. My pussy was leaking and it was all I could do to keep typing drivel into the computer in front of me.

I happened to look down for a moment and saw all the people below Matt. They could easily have seen him wanking if they looked up. I wondered whether anyone had seen him and was on their way to report him. I envisaged police cars turning up; officers cuffing him and leading him away to jail.

My knickers were now so wet, that I seriously feared for the leather chair beneath me. Either it too would be flooded or my juices would have sunk through to the cushion inside. Could I take the chance and just get up and leave him to it. I pulled at the tissues on my desk, preparing them to mop up the soiled seat when I lifted my bum off it.

No, I couldn’t leave him, I had to watch him spurt. It was the least I could do.

I slipped the bottom of my dress up a little under my bum, I let my fingers slide up my thigh until they touched the wet patch. Wet patch was a bit of an understatement. I was soaked.

Every now and then I was conscious of smiles cracking across my face as I watched my man masturbate opposite me. I suddenly felt like I wanted to taste him, but short of getting up and walking over there and taking him in my mouth, it would have been impossible. Especially with two double glazed panels and tens of feet of empty space between us.

I wanted to touch myself. I wanted to have a finger in my pussy when he ejaculated. Dare I.

Matt was pulling on his cock and I could tell he was getting close. He was continually looking in my direction. Well, in the direction of my office at least.

I dared.

I slipped my finger along my thigh until it touched my pussy. I pushed my knickers to one side while watching Brian opposite me, intently. I slipped my finger into my wet pussy. It felt so good in there and as soon as I was sure no one was about to engage me in conversation my eyes reverted back to Matt.

I suddenly became aware of Brian talking and realised that a question had been thrust towards me. Involuntarily my finger was thrust from my pussy and was firmly on the keyboard in front of me. I hesitated, trying my best to recall the words he used. Moisture smeared across the keyboard as I spoke.

“It’s in the same directory as the Decisions Log,” I told him, hoping that he would not get out of his chair and come to see my computer for confirmation. He didn’t. I had got away with it.

I thought that that was a little too close for comfort but I couldn’t help myself. My finger was back inside my pussy and my eyes were back on Matt. The pleasure I felt when my finger slipped back inside me was electrifying.

I don’t know how Matt lasted so long, but I know when he is about to spurt, and he looked pretty close a few moments ago.

For some reason my eyes were scanning everyone around me: The people in the café below the library and to one side of it, the people walking in the street, the little old lady that is only three desks away from him on the same floor.

I could see Matt concentrate on the tablet in front of him, then I saw his head tilt backwards and his hand quicken on his shaft. Then I noticed his hand slow up.

He was about to spurt.

I could tell from the expression on his face. I could see his joy and I could see him tense the muscles around his neck. I just hoped he never let out a grunt, like he normally did.

I suddenly felt it too. I started to move my finger over my pussy lips and when it hit my clit I nearly exploded. A few more strokes of this and I would be joining him. I watched Matt’s spunk jet out of his cock as my fingernail raked over my clit. It was the last stand for my sanity. My orgasm ripped through me and it was all I could do to stay upright and business like.

All of my body muscles were clenching at various parts of me trying their best to suppress any outward emotion of any kind. I was proud of myself that I never even let out a gasp or moan, and I daren’t let anyone know what I had just done.

I looked over at the library and saw Matt clean up the mess with some tissues; bless him, he had even come prepared for once.

There didn’t seem to be a commotion outside the library, no blue flashing lights, no police officers, no people aghast at what they had witnessed. I couldn’t believe he got away with it. I couldn’t believe I did as well.

I smiled at Matt before making my way to the toilet to clean myself up a little. I had prised my knickers back over my pussy but they were still a little uncomfortable. I lowered my skirt and was turning around in my chair when I glanced in Melanie’s direction.

Melanie’s mouth was open in disbelief. She was staring at the corner of the library, exactly where Matt was. My mouth started to open in disbelief and I was unable to move my eyes from her face. Realisation flooded over me, engulfed me, and thoroughly brought me back down to Earth.

All sorts of questions entered my head. Does she know him? Does she know he’s my boyfriend? Will she report him? Was she turned on? Did she come too?

I knew the ones I really wanted answers to but I also knew the ones that would hurt and embarrass me the most.

I got up from my desk and dusted down the chair with the tissues. I took my last look at Matt and saw that he had packed up his tablet and had put his cock away, back inside his jeans. I watched as he picked up his phone.

The only words that went through my mind was ‘don’t fucking ring me now.’

Matt couldn’t see the desperation in my face. It was then that my eyes followed Melanie out of her chair and as she left her desk my phone rang. I picked it up, praying that Melanie had not put two and two together.

“Hi!” I said, as I watched Melanie rush to the ladies loo.
