"We're never going to get this finished," Kate moaned to Sam as they spent another night in the office working on their report.

"All we need to do is relax. I think Mr Richards has a bottle in his office," Sam replied with a cheeky grin.

As Sam stood up and walked over to the door of the large office, Kate watched her curvaceous body move with the rythm of her walk. Sam's arse looked so firm in that little black mini-skirt, Kate longed to tell her how she was feeling, how she imagined her in her bed instead of Stephan; how everytime she had sex with Stephan shed picture Sam's body naked in front of her. But she knew she couldn't, so instead she followed her into the dark office.

"Take a seat" Sam said when she walked in, looking as if she owned the office. She took out the large bottle of vodka and poured two glasses. Kate sat in the Mr Richard's leather reclining chair and Sam handed her a full glass, perching herself on the desk facing her.

There was a slightly awkward silence in the room so, hoping to break it, Sam stuck out her pierced tongue.

"Oh god... that must have killed," Kate said cringing.

"It did, yeah - but not as much as one of my other piercings."

"Where else have you got?" Kate stumbled over her sentence. Sam had put one naked foot each side of Kate on the armrests of the chair to reveal one of the most beatiful cunts Kate had ever seen. In the dim light a little flash glinted from her clit and Kate took a closer look.

"Like the tongue, this makes oral sex even better." Sam said in her lucious voice.

"Oh really?" Kate said as she slid off the chair onto her knees in betweenb Sam's legs. She was nervous at first. She'd never done anything like this and didn't want to disappoint Sam.

She began flicking her tongue at the small piercing and Sam gripped her hair. She was already wet and Kate wondered whether she'd felt the same way all along. She happily continued lapping away at Sams flowing juices. She knew Sam liked it a little rough as they had revealed there turn-ons to each other over drinks one night so Kate began to teasingly nip at Sams lips while inserting her middle finger into her warm depths.

She started a motion with her fingers inside Sam, finding her spot and kissing and flicking her clit. Sam was moaning loudly with pleasure which turned Kate on so much she began to grind at her leg.

"Please don't stop." Sams managed to squeal out in between groans of ecstacy. Kate quickened her movements and Sam's whole body clenched and bucked. Her spine whipped back and with one last scream of lust Sam collapsed in the middle of the desk breathing heavily.

Kate never felt prouder of herself. She was dripping wet after such an erotic task and couldn't wait to taste Sam's mouth.

The women looked into each other's eyes before engaging in a deep passionate kiss. Sam, grateful for the immense pleasure she had just received, undid Kate's shirt and started teasing her nippples, knowing just how much Kate was aroused by them. She took one in her mouth and sucked it lovingly while pulling up Kate's skirt.

Kate lay back and let Sam pull off her thong. She was on the verge of cumming when Sam began carressing her swollen clit with her fingers, biting her nipples at the same time. She trailed kisses down to her bellybutton. Kate couldn't hold in her moans any longer when Sam reached her sopping cunt. She felt herself being explored and it felt wonderful. She had never before received this much pleasure from oral sex and couldn't believe how amazing it was. She let out noises she never knew she could and when she felt the first rush of bliss through her body, her back arched so much she thought it would break. A second wave soon followed and she knew thought would never feel as good again.

The women kissed passionately again, and lay entwined in each others arms, running their hands over each other's bodies. But reality beckoned so they fixed themselves up ro resume the report, rushing through it, before going for drinks. They parted with a deep kiss.

Kate arrived home and crawled into bed beside Stephan. He was fast asleep.

'Should I tell him now or should I just leave it?' Kate wondered. She knew he'd find it arousing but wanted to savour the memory for herself. 'I know. I'll wait till his birthday to reveal all,' Kate thought seductively and snuggled into Stephen thinking about Sam as she fell asleep.

The next morning Kate woke late to see a text on her phone. It was from Sam "Thinkin of workin l8 2nite... u up4it???"

She already knew how she'd respond.
