Arwen

'Arwen, Dr Derriere will see you now,' said Stephanie.

Doctor Derriere watched as a nerdy-looking, 18-year old ebony girl came and sat in the patients chair. Her black hair was neatly held back with a hair band. She wasn’t petite, but was slim and obviously toned, fairly average height, about five foot seven. Her face seemed cute and intelligent, although whenever girls had glasses on this seemed to be the case. Her stand out feature was her ample D cup breasts, which bounced delightfully as she walked. She had long athletic legs, shown off by the electric blue tennis dress she was wearing. As she sat down the doctor caught a glimpse of matching blue tennis knickers underneath. The dress rested pleasantly halfway up her crossed thighs. ‘Sorry I look such a state,’ she said, smoothing the dress, ‘I’ve just come from tennis coaching.’

'No need to apologise Arwen, and may I say what a well-fitting tennis outfit. How can I help you?' he said, wheeling his chair over to sit nearer her.

'I...was hoping for a female doctor, ' said Arwen nervously, 'But your assistant said it’s just you today?'

'I'm a doctor, I've seen and heard it all before, whatever it is, I'm sure I can help.'

'And you can't tell anyone, like my parents?'

'Anything we discuss, or do in this office is confidential. You’re 18, we’re both adults.’

‘Ok - we’ll the thing is, I’m used to knowing stuff, being in charge. I’m a straight A student, top of my school for SATs, I’m off to Harvard in the Fall. I keep fit, do sports, I play the violin. I’m good at everything, I’ve never failed at anything, ok? Passed the driving test first time, I ace every music exam, Math test, spelling bee, you name it, I can learn the skill or remember the knowledge.’

‘I sense a but...’ said the doctor, wheeling his chair from behind his desk to sit right opposite Arwen. She crossed and then uncrossed her legs directly in his view, giving him a flash right up her skirt.

‘You’re not wrong, there is a but, one with two tts- you see I’m also great at sex. Me and my boyfriend have been together a few months, he’s in my class at school, captain of the football team, a great guy. I’m a fast learner, I quickly became amazing at giving head, and I can grip his cock with my pushy on demand, we have great sex. But he wanted to try anal sex, and despite a few goes it just hasn’t worked, he says I’m no good at it, and I need to ‘train my ass’ but I just don’t really know what to do.’ She started crying.

Doctor Derrière put his hands on her thighs. ‘There, there, it cannot be nice being a failure. But I can help.’ She lofted her head and sniffed, his sympathetic face reflected in her glasses. Her face was suddenly filled with hope.

‘First I’d suggest a thorough rectal exam, just to check the area over, then I could suggest some butt plugs, dildos that might help - I’ve got an extensive collection. It’s just a matter of practising regularly. Or if you’d like I do offer a full anal service, that’s the examination and then a full ass fuck in order to ascertain any issues, plus the toys to take away.’

‘Whichever you choose you probably need to slip your tennis dress, sports bra off, and panties off,’ he said, ‘the examination table is just here.’
