"Happy Birthday to you" "Happy Birthday to you" "Happy Birthday dear Liiiiiisaaaaaa" "Happy Birthday to you" Another office birthday party! Little did I know how it would turn out! The day started in the usual way, alarm went off, got out of bed, trod on the cat, showered, got dressed, drove to work The day started to change around lunchtime. It was a colleague's birthday. Lisa was turning 30 and she wasn't too happy about it. The office took her to lunch, Italian. Food was pretty good, but the wine was better.

Most of the gang left to return to the office around two, but Lisa had gotten herself quite depressed about turning 30, so she and I lingered over a coffee whilst she sobered up a little.

Turned out he boyfriend dumped her a few days earlier in favour of a little slut he'd picked up at a McDonalds. After a couple of coffees Lisa had settled down enough to return to the office so we went back to work. I was a little concerned that Lisa wasn't enjoying her birthday and decided that she needed a little pick me up.

I asked her what she was doing after work but Lisa had decided to stay late to make up for the long lunch. I left work as usual and went to the local bar for a drink with the rest of the gang. Lisa said she was going to stay until seven so that gave me more than enough time. After a couple of drinks at the bar, and having several guys try to pick me up, I left. On the way out I bought a surprise present for Lisa and went back to the office. Our office layout is your typical open plan layout. Shoulder high partitions that give everyone a little, but not enough privacy. I made my way over to Lisa's cubicle. Being tall I could see over the partitions and as I approached Lisa's I could see that she wasn't exactly working.

On the screen was a picture of a beautiful red head woman being fondled by an equally beautiful brunette. I stopped and watched.

The screen changed to the same redhead now with her hand buried inside her softness. It was also obvious that Lisa was doing something similar with her left hand. I continued to watch as the next picture showed the redhead with a blonde head between her legs and a very large length between her lips. I was getting horny too and reached down to rub my own softness. Lisa shifted in her chair and propped one leg up on the open desk draw as she clicked the mouse and displayed the next picture. This one showed the redhead with a bottle of champagne. The next photo showed her pouring the champagne over her nipples. The next photo showed her with the bottle poised in front of the lips of her love. Lisa, by this stage was trembling whilst she pushed more of her left hand into her softness. "That looks like fun" I said in a hoarse whisper. Lisa spun around and stared at me open mouthed.

She had forgotten what she had been doing and still had her hand deep inside her. It was obvious that she was on the verge of an orgasm when I spoke. "What do you think she was going to do with the bottle?" I asked. Lisa swung around in her chair and looked at the screen then quickly shut down her computer. She also realized where her hand was at this point and withdrew it. To her great credit Lisa didn't try to deny having been caught looking at porn on the company computer and tidied herself up before standing.

"I'll pack my things and be gone in an hour" she said. I smiled.

"There's no need for that, " I said as I stepped closer.

"You still haven't answered my question! What do you think she was going to do with the bottle?" Lisa swallowed hard. She wasn't sure what to say.

She looked everywhere except at me. "I don't know, " she whimpered. I smiled again, and brushed a strand of hair from her face.

"Its okay honey, you don't have to go" I looked deep into her eyes and slowly bent forward.

Our lips met briefly and I could feel how dry her mouth was.

I cupped her face in my hands and kissed her again, more deeply this time. Although Lisa didn't struggle, it was obvious from her response that she didn't expect the boss to be doing this to her. I pulled away again and looked at her. She was scared.

But in her eyes I saw something else, curiosity, defiance, and sexuality, all of these things. I kissed her again, this time probing her mouth with my tongue. She responded. Her hand dropped to my breast and gently rubbed my nipple through the material of my blouse. I stopped the kiss. I took her hand and led her through the office to the conference room. I opened the door and ushered her inside.

I followed her into the room and carefully locked the door behind us.

I went to the fridge and took out a bottle of champagne. I offered her a drink and she nodded. I poured us a drink each and gave her a glass. She drank deeply and placed the glass on the conference table. I refilled the glass and stepped closer. I took a sip from my glass then offered the rest to her. She smiled and acceptance and I stepped closer to her.

I offered the glass to her lips and she accepted.

I tipped up the glass and poured the sticky contents across her lips and onto her neck and blouse. "Oh, I'm sorry. You'll have to take that off now" I smiled. Lisa slowly unbuttoned her blouse and removed her bra. She then unfastened her skirt and stepped out of her panties. All she had on now was her shoes, a string of pearls and her lipstick. My body trembled involuntarily and I felt a bead of liquid trickle slowly down the inside of my thigh. I motioned for Lisa to sit on the conference table.

She complied, running her fingers across my crotch as she stepped past me to sit on the table. I smiled and stroked her hair. I stepped closer, spreading her legs apart with my legs and bent forward to toy her lips. A low moan escaped her mouth and I brushed my tongue across her lips and down to her neck. My right hand strayed down her body to her crotch.

I found that Lisa was wet beyond my wildest expectations and quickly slipped three fingers inside of her. She gasped at the initial sensation but quickly relaxed and moved in time with my hand.

I withdrew my fingers and reached for the champagne bottle. I nuzzled my lips to her ear. "Did those pictures excite you?" I asked.

"Uh huh" moaned Lisa "Does the idea of being with a woman excite you?" I asked as I slowly shook the bottle of champagne. "Uh huh" whispered Lisa as she reached down to finger me. "No" I whispered, "Play with yourself, make yourself wet" Lisa slowly rubbed her personal place whilst I shook the bottle and kissed her lightly on the lips. We held this embrace for minutes. It was obvious that Lisa was approaching orgasm as she expertly played with her personal place and love. "Are you ready?" I asked The only answer that I received was a low moan and a gasp. Lisa was coming now was the time. I placed my lips against her ear and gently nibbled it.

Lisa was coming now, a deep long orgasm that I was going to enhance. He body started to shake and her hand was moving quickly across her personal placeoris. I moved the bottle lower, close to her already teasing cunt. She was frigging herself harder now her hips were bucking as the orgasm engulfed her body and mind. I moved the neck of the bottle against her thigh the peak of her orgasm was here now. I took my thumb from the mouth of the bottle and let the champagne spurt against her hot personal place and splash into her love. She gasped as the cold liquid struck her softness, and then laid back and let the pleasure of the orgasm roll through her. We rested in that room for about an hour before we ventured out. Lisa had to wear my jacket as her blouse was in no state for being worn in public.

I drove her home and stopped for a lingering sexy kiss at her door.

She begged me to come in but I declined. Lisa, I found out later fell asleep in the bath that night.

The next day at work, there was a letter of complaint from the cleaning supervisor. It appeared that some of the employees had a party in the conference room last night. The carpets were a mess and the bar had been opened. If only he knew the truth!
