Second payment

Dan put his arm around Sarah as they stepped out of the room. Sarah didn't initially say anything until he slid his hand down and got a good feel of her arse. At which point she spun away from him "Dan," she cautioned "That wasn't in the deal." Dan just grunted in annoyance and went to unlock the door or the treatment room and opened it for her. She went in and Dan locked the door behind them.

The room had a large unusual looking device against the far wall and two beds on either side surrounded by more familiar medical equipment. There were a couple of computers and some chairs but it wasn't an exceptional looking room. Sarah couldn't help but be interested in the device and she moved over to have a look. There were what looks like bags attached with pipes hanging on either side of it. Sarah assumed that the patient was placed inside one of the bags on the bed but beyond that its workings were a mystery.

Dan grabbed Sarah's hand and pulled her towards him. She found herself pressed up against him with her hands on his chest. She was about to protest when she got distracted. His chest was firm with muscle. She couldn't believe he was this toned under his ill fitting clothes and was he taller or was he just standing up straight for once? She pulled away slightly but didn't back off. She could let him play his games a bit as long as he didn't try to push it.

"Hey," said Dan, a thousand times friendlier than he had been speaking to Tom. "are you ready to make another payment?" He was stroking her cleavage with the back of his finger again.

"I already gave you the cash" said Sarah playing her part and staring him down.

"You know what payment I'm after" he replied as he started to unfasten her top from the front.

"I don't remember them being a part of the deal."

"You know I feel about your crappy deal. Anyway don't pretend you didn't like me touching them last time." Sarah made to protest but Dan cut her off as her tits sprang free "If it helps just think about how much it will turn me on. Makes your job easier doesn't it?"

Sarah wanted to be careful how she answered but in her moment of hesitation he softly squeezed her breasts. Her cock twitched painfully in its pantie prison as her sensitive breasts sent shivers of arousal through her body. He was kneading hen and playing with her nipples. She knew she had to stop him or he would get ideas but damn it felt good. "Dan I don't..." She began but Dan interrupted her.

"Shh, stop being so uptight and pretending you don't like it. It's written all over your face" he said softly. "Take my cock out, my hands are busy."

He was being so pushy but his hands did feel good and it had been a while since anyone had been so assertive with her. I need to make him cum anyway she justified to herself as she reached down and grabbed the bulge in the front of Dan's trousers and gave it a soft squeeze that matched the attention he was giving her breasts before unfastening his belt and trousers and slipping her hand into his underwear. She wrapped her hand around his thick shaft. It's bigger than I remember. He does have quite a sexy cock she thought as she pulled it out of his underwear and ran her hand over it slowly.

"You like my cock don't you?" smirked Dan.

"It's just a cock" she answered defiantly.

"Yea, keep telling yourself that" he said as he pinched her nipples causing her to bite her lip and moan in a mix of pleasure and pain she found intoxicating. Her cock was massively uncomfortable now but she pushed it from her mind as she began to masturbate him.

For a while they stayed like this. Dan toying with her breasts while she worked his cock with her had. Dan held her gaze and it was intensely intimate. Suddenly Dan let go of her breasts an pulled her close to him, his hands rested on her buttocks as he pulled her into him. His face came close to hers Oh my god he's going to kiss me she thought as his face came close. Almost instinctively her face lifted to meet him before she could stop herself. Dan didn't kiss her but leaned in close to her ear and said "Show me your cock."

Sarah's eyes went wide and she panicked backing away from him. "How did you? I mean, I don't..." she stammered.

Dan leaned against one of the beds and smiled his insufferable smile "Then your pussy is hard as a rock" he said crossing his arms and feeling pleased with himself, his cock pointing out in front of him lewdly. Sarah continued to stammer explanations or denials. Dan sighed and pinched his nose "I don't care. You're hot I don't give a shit what's between your legs. I mean, I have a shit ton of questions like how are your tits so big from hormone growth and why is your bone structure so feminine? You don't have to tell me if you don't want to. I still want you to suck my cock but I'd appreciate you not trying to deceive me."

"I was born a woman, it grew more recently." She had covered her breasts and was looking away in embarrassment.

Dan's eyebrows raised "You know that's unheard of right?"

"Yea, that was one of the reasons I was hiding it."

"Fascinating" said Dan and he had a smile on his face that Sarah felt could only mean trouble. "Take your panties off."

"What?"

"Come on, stop fucking about and take your god damn panties off. We both know that there is something off about you and I would rather not threaten you so take your panties off."

She knew he was right. There was little he could realistically do, nobody would violate her human rights because she might have a penis but he might draw unwanted attention to her and Tom and with what she was trying to do to her husband, privacy was the preferred option. So he knew she had a cock, she wasn't ashamed of it.

She took a breath to centre herself and, standing in the middle of the room dipped her hand under her skirt and pulled down her panties. She pulled them off her boots and Dan held out his hand. She rolled her eyes and threw them to him. He slipped them in his pocket. Her cock had softened a little over the fear of being found out but now it was brushing against the fabric of her skirt coupled with the erotic tension in the room it was starting to swell again and was beginning to push the front of her skirt out.

"Don't be a fucking tease. Lift the skirt up, I want to see" said Dan.

She might not be ashamed of her cock but displaying herself for another man was embarrassing. She blushed deeply and looked away as she lifted the front of her skirt. The humiliation made her cock rock solid and it stood proud and throbbing as she displayed herself for Dan. She plucked up the courage to look at him and he was stroking his own cock while looking at her.

"You look straight out of a hentai and that expression is fucking hot. You've got a pretty big dick babe but I think Mine's bigger. Come here, I want to check."

Sarah moved towards him. A dark part of her was curious as well and her arousal was clouding her judgment. He pulled her around next to him and pulled the fabric of her skirt off her cock. It was pointing up and she didn't need to hold the fabric away to keep it uncovered. Dan put his hand on her hip and pulled her up to him so their cocks were close. "Heh, looks like I have you beat babe" he gloated. He was right. It wasn't by much but he was a little thicker and a little longer than she was and she knew she was well endowed. Tom Had a good sized cock and she was easily bigger than him. Dan was clearly gifted in the cock department.

Dan's hand had drifted from her hip onto her bottom but it felt insignificant compared to standing there with their cocks out. He gave it a firm squeeze, making her jump "Come dick girl, get down and suck that cock instead of staring at it."

Tom was torn between her arousal and not wanting to seem give Dan the impression she was into it although the fact that her cock was as hard as stone was a bit of a giveaway. She put on an annoyed expression as she lowered herself to her knees and took a hold of his cock. She was breathing deeply. Being **** into sucking him off had ben arousing enough but now she had had her secret exposed. Displaying herself to him had made her heart pound in her chest and her face flame with embarrassment. She had never been in a situation like it and it had made her quite giddy.

Putting his cock in her mouth was easier the second time but she did feel like there was more in her mouth than last time. Maybe he was more aroused because he hadn't spent the previous evening fucking. She explored the shape of him with her tongue between slurping and pumping it in and out of her mouth.

Dan stopped her "I've had an idea" he said as he turned her face up to look at him "Get on the bed."

Sarah stood up "I'm only sucking your cock you know."

"Yea, I know, just do it" said Dan sounding annoyed by her words. As Sarah climbed on the bed he grabbed hold of the controls and the bed started to lower. "Lie down" he ordered her and shrugging, she did. The bed lowered he moved to where she had put her head. She now saw what he had been getting at as she moved closer to the edge of the bed and turned her head to begin sucking him again. "Yea, you get it. Now I can see you properly as you slurp on that dick."

He reached out and groped her bare breasts. She didn't stop him. She was **** for the stimulation. Her cock twitched obscenely as he pinched her nipple and little moans started to escape her throat at the sensation. Her sucking became more enthusiastic as her enjoyment grew and by the sound of the noises Dan was making, so was he.

"Fuck, that's good. Play with yourself while you suck me. Your cock looks like it's ready to burst" moaned Dan.

Sarah gripped her cock and pulled back hard. A deep pleasure ran through her and she let out a groan around Dan's thick cock. She felt like she could have almost cum but that first wave of pleasure dipped away and she slowly began to work her cock while not slowing down on Dan's.

"Ha, I never thought I'd see a scene like this outside of hentai. Stroke it bitch, I'm going to fill your mouth with my cum."

Right at that moment the idea of Dan cumming in her mouth was just the sort of dirty thing she wanted and she jerked her cock and his furiously until Dan had to grab her hand to stop her so he could cum. Cum flooded her mouth and she held it there a moment relishing the obscenity of the act before swallowing it down her own orgasm reaching the point where she would cum even if she stopped. A moment later she gasped as she came her cum splattering her skirt and stomach.

"Fuck, you cum like you're in a hentai too. Gets you off having my dick in your mouth doesn't it?"

Sarah didn't say anything as she basked for a moment in the afterglow of her orgasm then the feeling of drying cum made her aware of what a mess she was in. "Oh shit. I'm covered. My skirt is a mess. I can't go home like this? What would Tom say?" There was a pang of guilt when she thought about Tom. Not so much from her sucking Dan off. That part of it felt transactional and not her choice. The fact that she had enjoyed it and was now covered in the evidence of that fact was what was making her feel uneasy.

Dan was rummaging in a cupboard and returned with a roll of paper towels and a lab coat. "Clean yourself up and put this on. We can tell him you spilt some chemicals down yourself. I just need a few days to process his data and then we can book you in." Dan was clearly back in business mode. "I will need to call you to iron out some details about his final appearance but all being well I propose we do it a week on Saturday. How does that suit you?"

As odd as it felt to be speaking so frankly while cleaning cum off herself it did succeed in distracting her from her guilt. "Yes, I'm free. Is there anything you need to show me about the equipment before I go?"

Dan laughed "The only equipment I needed to show you was mine and you already had a good idea of how to work that."

Sarah blushed as she put her top back on followed by the lab coat. "Right, well I suppose I'll speak to you soon" she mumbled as she headed to the door only to realise it was locked.

Dan came over and unlocked it to let her out and stood too close to her "Yea babe, I'll speak to you soon. Looking forward to that final payment" he smirked as he slapped her ass as she walked out and went to retrieve Tom.
