Matti's mind raced as he packed. The young man, 27 years of age, and in his third role out of university, was being sent away to a conference for a few days in the heart of the Norfolk Broads. He was to accompany his older colleague Su, who as it happened owned a cottage nearby, and so she had offered to put him up for the duration of their stay. Not only that, but she had extended an invitation to stay on, as she herself was, and enjoy a few days in the country.
He put her in her late forties, perhaps 20 years older than himself. She was attractive in the way women of her age are; a more mature, sensual beauty than the smooth perky prettiness of girls in their teens and twenties. Of average height, slim and in good shape, but with full breasts and hips, she had caught his attention from day one. He worked closely with her, but was not entirely comfortable in her presence, never quite able to relax entirely.
Though by no means sour or miserable, she had a stern, no-nonsense manner about her. She was attractive and friendly on her own terms, but she had the effect of making him feel like a young boy when she turned her particular glare upon him. Certainly she brooked no nonsense, and although they were technically equals, he found himself deferring to her often.
Whilst the other men of his age in the office chatted about the flirty young girls in sales, the CEO's aloof EA, the French beauty on reception, Matti's sexual thoughts often drifted to Su. In his regular masturbatory fantasies, she was as stern and dominant in the bedroom as she was at work. He didn't so much choose to fantasise over her, it was almost as if he had no choice. As he lay in bed, cock in hand, thinking of the pretty intern sitting across from him, or the girl he'd noticed in the canteen, his mind would often move to Su of its own accord. Even his private sexual thoughts seemed to be under her control.
He considered himself reasonably good-looking; tall at 6'2", in good shape from sports and running, with short strawberry blonde hair, and blue eyes. He was single, confident with women, and had a satisfying sex life. Still, he couldn't shake how su made him feel.
With that in mind he approached the trip with a little trepidation. He didn't know how he'd react alone with her for an extended period.
The drive down to Su's cottage was uneventful, with the chat focussed around work, life, the latest current affairs. Pulling up outside a handsome stone building Matti was impressed, telling Su so, her grin letting him know how proud she was of the property.
Set a short way outside a small village, set in its own secluded garden, the building was a former schoolhouse. The cottage's simple layout was of a large central room, entirely open plan with a kitchen at the far end, and a bedroom and bathroom off it to one side. Up an original oak open staircase, was located the ensuite master bedroom on a mezzanine level, an open balcony at one end looking out over the room below.
Matti was directed to the ground floor room, whilst Su took the upstairs. They ate a simple meal that evening, after which Su went upstairs and showered. She returned in a dressing gown, which whilst modest, didn't disguise the fact that she was likely nude underneath it. Matti had been going to just go to bed, but in the end went for a shower himself, masturbating to a quick orgasm, his mind racing with thoughts of her.
The conference lasted for two days, and was interesting without setting any pulses racing. By the afternoon of the second day, Matti had begun to feel a little feverish, passing up on the buffet lunch, and feeling exhausted, flitting between hot and cold by the time they got back to the cottage later that evening.
He had passed up the offer of an evening meal and was sat upon his bed when Su bustled into his room, walking over to him. She placed the back of her hand to his forehead.
"Hmm... you're rather warm. I'll fetch a thermometer."
She hushed his protests,
"Nonsense, if you're coming down with something I want to know. I've no desire to catch it from you."
With that Su turned and walked from the room, returning moments later with the device in her hand. She stood over Matti, looking down at him with that no nonsense look upon her face.
"I only keep rectal thermometers in the cottage. Sole reliable way to take a person's temperature, so you'll need to slip the clothes off your bottom half."
Matti stared at her aghast, his mouth opening to protest.
"Don't be silly, we're all grown ups" she admonished him, before he could speak. "Yours won't be the first boy's bottom I've seen."
This was the moment, unbeknownst to Matti, that their relationship tipped over. He was an adult, with no reason to take command or suggestion from this woman. And yet, despite blushing furiously, the sheer embarrassment of what she was telling him to do, he found himself looking down at the floor, his fingers reluctantly fumbling at his belt.
"Hurry up," Su said impatiently, tapping the thermometer against her thigh. There was no suggestion from wither that she would turn away whilst he undressed. What would be the point after all?
Matti studiously avoided Su's eye as he stripped from the waist down, his jeans and underwear folded beside him on the floor.
"That's it, sit with your bottom at the edge of the bed, then lie back, and raise your knees to your chest. Come on now, we don't have all day."
Matti held on to the underside of his knees, keeping his legs high, exposed in a position he hadn't been in since he was a baby. He stared up at the ceiling, willing the moment to be over.
The bed creaked as Su sat down on the edge of the bed beside him. He heard the pop of a bottle cap, then the lightning jolt as for the first time in his adult life, another person touched his anus. He couldn't help gasping as she began to rub lubricant on his opening, a quiet moan escaping his lips as he felt the tip of Su's finger slip briefly inside the tight ring of his virgin body, then quickly replaced by the thermometer, the slim cool implement sliding easily up inside his hot rectum.
"Any pain when going to the bathroom? Hmm... and how about this, does this hurt?"
As Su held the thermometer in place, gripped snugly in his anus, she pressed two fingers of her free hand against his belly, pressing down in different spots, asking him each time if he felt any discomfort. Matti could only shake his head and murmur no each time. Twice her hand brushed his penis, and a mortified Matti became aware that the contact was causing him to react physically. He wasn't erect, but his penis was noticeably longer and thicker than it had been when Su had told him to undress.
After what seemed an age, the thermometer beeped, and Su eased it out of his bottom, looking at the reading with a face that said she wasn't entirely satisfied with what she was seeing.
"Not dangerously high, but worth keeping an eye on. A bath, and then to bed I think."
Su stood, looking down at him, her face impassive.
"Finish getting undressed, then come next door to the bathroom."
As she turned and left the room, and the sound of running water started up almost immediately from the adjoining bathroom, Matti realised he was still in position, bearing his bottom. Blushing, though no one was there to see it, he lowered his legs and sat up, pulling the hem of t-shirt up, discarding the clothing on to the pile on the floor. Hesitating for a moment, it crossed his mind that Su wouldn't appreciate untidiness, and without stopping to question why, he quickly folded his clothes away neatly. Naked, he padded next door to the bathroom. Su was there, bent over the bath, testing the temperature of the water, her back to him. Matti stood awkwardly, feeling more aware of his nakedness, strangely, than he had when on his back exposed moments earlier. He shuffled, hands alternately cupped in front of his genitals, then by his side, unsure which looked more silly.
Satisfied with the bath she had drawn, Su stood, and motioned to him to get in. He did so, easing beneath the water, sighing as the warmth washed over him. He half expected Su to leave him in privacy, but she sat down on the side of the bath, picking up a lightly scented soap bar and passing it to him. Blushing in a way that he dreaded but she already found rather endearing he began to wash his body, turning a crimson shade when he needed to stand, his genitalia at the same height as her face, and the older fully-dressed woman made no allowances for his modesty.
She watched impassively, but not looking away, as he soaped a lather up on his belly and legs, then when he could no longer avoid it, between his thighs.
"Don't forget your bottom."
Blushing again - would he be red faced for the rest of his life he wondered? - he ran his soapy hand down between his buttocks, building up a lather between the pale cheeks.
"Inside," Su directed, as if he was missing an obvious instruction.
