butt hole examination

'Could you, maybe,' Chastity had turned shy again, 'examine my butt, and check its you know, normal?'

'Of course. Hop up on the examination table and strip to the waist please.' Chastity walked across to the examining table and the doctor pulled the curtain around. 'Let me know when you're bottomless,' he said.

Chastity undid her skirt and pulled down her cotton panties, then took off her socks and shoes. She felt incredibly exposed, the only person who'd even seen her pussy was Brad, her boyfriend from next door, but mostly they'd been in the dark when she'd let him finger her, or she'd sucked him off. She clambered onto the table and said ' I'm ready now.'

Doctor Derriere pulled the curtain back and looked directly at her pussy. 'Lovely he said. You've got a fine body, your boyfriend is very lucky.' She gulped. He produced some medical gloves and put them on each hand, eyes fixed on her pussy. Like most religious girls she had an unshaven pussy. 'I think we need you on all fours actually, for a better view.'

'Oh, ok, of course.' She turned onto her knees, pointing her virgin pussy and ass up in the air into the doctor's face. She could feel his breath on her pussy. 'Everything looks perfectly normal to me at first glance,' he said, 'just arch your back a little. Perfect.'

'I'm going to start the examination now.' She felt his gloved hands on her back. He seemed to be caressing the small of her back, then her buttocks, moving in circles, lightly rubbing and pulling them apart. She felt her anus open slightly each time her pulled her ass cheeks apart. She felt a finger on her rosebud and tensed. 'Just relax Chastity, this is a perfectly normal rectal exam, nothing to worry about. If you're worried you could play with your clit whilst I probe your anus with my fingers, just to check its shape and suitability for fucking.'

She was pretty worried, so she put her right hand between her legs and started to frigg herself. As she did so she felt the doctor's index finger slide into her ass, just the tip at first, and then the whole length. She gasped, feeling the invader in her ass and her clit growing as part of the same sensation. 'It'll probably feel a bit uncomfortable,' said Dr. Derriere, 'when I move the finger in, push out with your bottom, ok.' He started fucking her ass with his finger, and Chastity started moaning.

'I'm going to add another finger,' he said, and she felt her sphincter expand to accommodate his middle finger too. she could feel both of his fingers as her butt gripped them. She couldn't imagine a cock being in there - what must that feel like? Without saying anything a third finger was added and she frigged her clit even harder, before realising that she was about to come. She realised this too late, and bucked like a bronco, struggling to remain on her knees as her orgasm spread throughout her whole body. 'Sorry doctor,' she said, still convulsing. 'Please don't apologise,' he said, with three fingers buried deep in her ass. He was twisting and turning them now, presumably all part of the rectal exam.

‘Chastity I think you are perfectly suited to anal penetration, I’ve got three fingers up you beautiful bottom without much trouble. And you have clearly enjoyed it too. I don’t think you have anything to fear from a cock up your bottom.’

‘What does that feel like? I’d like to be completely prepared, if you’re still sure it’s safe and not a sin. Is there a way of experiencing it before actually doing it?’

The Doctor withdrew his fingers and watched, licking his lips, as her sphincter gaped ever so slightly.

‘Well Chastity, it is always good to be prepared. I have a range of realistic dildos we could use right now to simulate the act, or if you prefer I could use my cock to show you exactly what to expect.’

‘You mean, you’d fuck me right now? In my ass? What about my boyfriend?

‘You’re doing this for him, to avoid sinning against God, remember.’ He stroked the girls ass cheeks as he spoke, rubbing her brown bud with his index finger and inserting the tip slightly. She pushed back.
