Agatha was making eyes at her. It was very distracting. She was going to fill in the expressions on the sketches and be done with it. She was getting bored of this art class malarkey. She could be doing other things in her spare time. Like Agatha. The woman was teasing her, making her wait. Dimity could only simmer for so long. She wanted a good hard shag and she wasn't going to be picky about how she was going to get it.

'You could do a bit more shading here and there' Pippa pointed out. 'And really work on the expression.'

That was the problem, Dimity thought. How could a sketch capture Agatha's expression? Especially from someone who only recently graduated from drawing stick men.

'I might finish it at home to be honest, I'm finding that difficult.'

Dimity hoped that it would serve as a subtle reminder to Agatha that she wanted her wrapped up in her duvet. To her disappointment, Agatha did not engage with it.

'It's a work night, I'll take a rain check' said Agatha casually, once the last pencil stroke had been administered.

'Bit boring of you, isn't it' said Dimity, not willing to let her get away so easily. She regretted her words when Agatha shot her a basilisk stare.

'Anything of quality, takes time. I'll contact you.'

Dimity wondered how long it would take for Agatha to get frustrated and move in on her. She reckoned she might be waiting for a while. She spent her downtime looking at the unfinished sketches, not sure if she could complete them.

Wrong again. Agatha contacted her on Friday morning, instructed her to pack an overnight bag and to bring her sketches.

I would expect as an educator, you would hate to see a student leave a goal unfinished.

Damn the woman. Dimity read the message several times, knew she was being played but Agatha had got the measure of her. Dimity strove to achieve her goals, even if it was something like the art class that she had little interest in. She was a student who wanted to finish that achievement. They both wanted to bed each other so why wait?

They met by Agatha's favoured pizza place, shared a bowl of chips. It felt like they'd known each other for longer.

'What are you thinking?'

Agatha rarely asked this question. But Dimity was cute, a bit earnest, sometimes a bit braggy but Agatha didn't mind that. She felt it was honest. Fake modesty irritated her. And she liked it when Dimity showed off her confidence.

'I barely know you but somehow you feel strangely familiar.'

'That's what happens when you see someone naked before you sleep with them.'

They laughed and talked about work. Agatha had trained to be a teacher but she really hadn't the knack for it.

'I prefer working with animals. Less headache.'

'I love teaching, it's such a challenge working with young minds. Yeh they can get a bit gobby and sometimes I have to play the detention card but I feel like I've really done something worthwhile. They spend so long sitting at desks and learning from books and doing chemistry experiments that when P.E. rolls around, they bitch and complain about it but really once they get out into that fresh air and move, most of them feel exhilarated after. Gives their brains a break. Sometimes there are too many words rattling around the atmosphere, exercise gives you a refreshing focus you don't need to recall for a test.'

Agatha smiled wistfully at Dimity's enthusiasm, something she'd tried to gain herself and had failed. She confided that nothing she ever did was good enough for her family and so she thought fuck it she'd do whatever she wanted. She'd done several wild and unpredictable things but when their mother had become ill, she'd returned home and helped her sister.

'She's Miss Perfect. Headmistress like mother was. We're identical twins' she explained. Dimity dropped a chip.

'There are two of you?'

'Technically. We used to be close. Although we're actually very different personalities. She dresses like a librarian, she bakes and crafts. Not my kind of thing. I went off the rails for a number of years. It's been a few years since we've really started to make the effort with each other. Since our mother died, we've been working on it.'

It was a matter-of-fact candid confession and Dimity realised that she'd been given the privilege of hearing something deeply personal. Agatha wouldn't have divulged this information without an element of trust for the recipient. She had a reputation to uphold after all.

'I find you even more fascinating knowing that you've allowed me to peek under a layer.'

Agatha's predatory smile was back. She had plans for Dimity peek under a lot of layers, starting with her dress.

'You're coming back home with me' came the silky order. Dimity didn't argue. She wanted to see how Agatha lived. What colour her duvet was and what delights she hoarded. They sped off to a townhouse near the centre, emerald green bedding and underfloor heating. They could have fucked on the bathroom floor. But Agatha favoured her queen size bed. She liked luxury. When she laid Dimity out among the high cotton thread count sheets, the other woman felt like she was a damsel in distress being rescued. Her mind went blank as she surrendered to the astonishingly tender attention lavished on her. Agatha was a tremendously good kisser and the other woman melted against her in an agony of yearning, clung to her in ecstasy. It had been a long time that such simplicity had seduced her.

'Don't think you'll be going anywhere for the weekend' came the whisper and Dimity settled in for a thoroughly filthy evening. When Agatha trailed her tongue tantalisingly slow down her midriff, down past the tangle of damp curls and firmly into the nooks and crannies designed perfectly for an enquiring tongue, Dimity thought she'd died and gone to heaven. Her clit was swollen and needy, she was making noises she hadn't thought she was capable of and she didn't think when Agatha let her push her head down, drowning in Agatha's appreciative moans that vibrated through her body. She only cared about her orgasm and Agatha was happy to give it to her. Her strategy was to give first, demand more later. She was going to ride Dimity hard and she knew she was hers for the taking.

'Now, I think it's about time for you to do some work.'

Panting with exertion, Dimity only had to think about returning the various favours to get her going again. But Agatha had something else in mind. She rolled out of bed and brought over the sketches, making Dimity draw her expressions as promised, erasing anything she wasn't happy with. Dimity drew for half an hour, getting more and more frustrated. Agatha would not give her anything more until she was happy with the sketch. She kept going, doing as she was told until Agatha pronounced it to her satisfaction. With a sigh of relief, Dimity left it on the chair and flopped back onto the bed.

'Your mind needs a different kind of focus after all of that academic striving' teased Agatha, taking a thwarted nipple in her mouth. Dimity sighed happily and pulled her on top, folding her legs over her back and locking her in. Agatha teased her with a finger, making her groan with anticipation. Agatha liked the sound of a ready and willing woman. She murmured that she felt a change of pace was needed, obtained a breathy sigh as consent and thrust her finger inside the eager cunt. Dimity shuddered and yelped. Agatha carried on sucking while crossing two fingers over and gliding it in and out, confident that Dimity would get the best fingering of her life. When Dimity had recovered, she decided that celibacy was overrated. She released the other woman with her thighs, pleased that she had kept up with her exercises. She had a strong grip. She was not too exhausted to decide how sexy Agatha was when she sucked her fingers clean.
