The woman stopped her taunting and groaned as he began to squeeze her left boob, allowing him to free his other arm and reach up to her other breast. They continued in that position, her crotch over his face and him squeezing her chest, before she reached down and pulled her panties over to one side, putting her naked pussy directly onto his mouth. She moaned louder as her brother started to eat her out.
“Man, this is torture,” said Jon.
“You mean the tenuous story arc going on here?” Emma quipped.
“The contrived plot is definitely something, but I mainly just mean this setup. The heat of the room and watching porn without… you know… being able to act on it.”
“I thought you weren’t into incest…”
“I’m not, but it’s still porn I guess. It’s hard not to get aroused at two attractive people cavorting about like this, even if they are pretending to be siblings. But all I can do is sit here and be blue-balled by it.”
“Yeah, I’ve definitely never watched porn for this long without getting off before.” Emma cringed the moment she said that, realising that she’d just openly admitted she masturbated to porn to her father.
“At least as a girl you can slip your hand down there and help yourself a bit,” Jon said, “I’m pretty much stuck without getting half naked.” At her dad’s words Emma immediately drew her hand out of her pants. She wasn’t sure if her dad knew she was touching herself or not, and realised in hindsight she probably responded a little too quickly.
“Oh yeah sure Dad,” she decided to protest, “like I’m just going to get myself off while you’re sat here next to me. Even if girls can do it with their pants on, I’d have a hard time keeping myself quiet or staying discreet about it if I was trying to get some real relief.”
“I guess… sorry… I shouldn’t have brought it up.” Jon blushed. The talk about masturbating hadn’t helped him feel any less aroused. He couldn’t remember the last time he’d had an erection for such a sustained amount of time. Even knowing he was being observed and with his daughter sat next to him, it was taking a lot of willpower to not start touching himself. The couple on the screen had now changed positions again, and had seemingly abandoned their wrestling match as the two settled into a sixty-nine. “At least it looks like we’re into the last ten minutes.”
Jon looked across at his daughter and it struck him how much she looked like her mother when they had first started dating. He realised how much she acted like her too, how she was happy to be adventurous and was open to new things.
He wondered how differently this would be if he was sat next to his wife when they were that age, rather than his daughter. They’d definitely at least have masturbated, possibly even would have fucked on the sofa, giving the researchers a proper show. He thought back to all the wild stuff they did when they were in their teens and early twenties. When did he get so uptight and boring? Was it his age? That he’d been single for so long? Or does being a parent just do that to you? He needed to loosen up a bit.
The couple on the screen had now progressed to full-on sex, with the woman on all fours as she was pounded from behind by her brother. “Mmhm yes, fuck me bro,” she grunted, “fuck me hard, ugh, yeah that’s it…” He flipped her over onto her back and resumed his rhythm into her as she moaned loudly and pulled him in for a deep kiss. They continued for a few more minutes before, both grunting and panting towards orgasm, he pulled out. The woman quickly flipped forward to wrap her lips around his cock and let him finish inside her mouth. She swallowed. “I think we should have a rematch tomorrow, little brother,” she said, before the video faded to black.
Jon and Emma sat in silence for a few seconds with the blank screen in front of them, slightly unsure what to do next. Suddenly the door opened and a different man to the one who had recruited them walked in.
“Hello,” he said, “I am Professor Adams, the lead researcher for this study. If you’d like to collect your things and accompany me back to the lobby then I will arrange your payments and we can conclude this session.”
Emma put her clothes back on and they walked with him back down the corridor towards where they first entered. Jon continued to hold his fleece in front of him so as to hide the large tent in his jeans as he walked. On the table in the waiting room were two envelopes. “Please take an envelope each,” said the Professor, “They contain your compensation for the trial, along with information for how to attend the follow-up sessions later this week if you wish to do so.”
“Thanks for the offer, but I think we’re good,” said Jon, picking up both envelopes and handing one to Emma.
“I got the impression from your comments during the session, Mr Brinkley, that you don’t approve of our research. That’s understandable, we are for sure pushing the boundaries of what most people would deem acceptable. Though I would argue that without pushing boundaries in studies like this, it is difficult, if not impossible, for science to extend our collective understandings of human psychology and social interactions. You were put into a very unexpected and atypical situation this morning; however, it is only in such situations that we can observe behaviours that are less understood.”
The professor paused, as if to let his comment sink in, before continuing. “I would like to thank you again for participating in our research, you will see that you have both received your fee in full. I wish you all the best for the rest of your day, and I hope to see you again. The exit is down the stairs, the way you came in.” He gestured with his hand to the doorway.
Jon and Emma headed down the stairs and stepped outside. The chilly February air felt particularly striking in contrast to the warm facility they’d just left. “Well,” said Jon, “I’m guessing that wasn’t in the guidebook… where should we go now?” Emma was busy checking the crisp notes in her envelope.
“I think,” she said, “that we should find a nice place for lunch, an even nicer place to make a reservation for dinner this evening, then we can go to that art museum. And at some point, I’m going to buy myself a new dress with this cash.” Jon was a little taken aback with how bouncy and energetic his daughter suddenly seemed, and how she appeared to be completely unaffected by the last hour.
They had their nice lunch, booked a table for the evening at a place that Jon suspected was going to be providing the most expensive dinner he’d eaten in a long time, and then wandered around the local art gallery. The whole time Emma had a beaming smile on her face, dragging her father around and explaining the significance of some of the pieces in the gallery. Jon would have found her enthusiasm contagious and had to admit he was having a pretty good time, but his mind was still lingering on what they’d done this morning. Not just his mind, in fact, but his libido as well – his erection had subsided, but he couldn’t shake feeling massively horny the whole day.
They wandered back to the high street so Emma could go shopping for a dress for the evening. She too found that she was still incredibly turned on as she browsed through the sultry garments while her father waited outside. She picked a few to take to the changing rooms and try on.
She admired her figure in the mirror in the different dresses. One dress was dark blue and had a top half consisting of two fairly narrow fabric straps that hooked up over her neck, leaving her back exposed and presenting a fair amount of cleavage and the side of her breasts. Another was black with a long slit in the lower half, showing off her toned legs and threatening to expose the waistband of her underwear. A third one was red and tight fitting, accentuating the hourglass shape between her breasts, her toned waist, and her hips.
She noticed as she changed out of the last dress that there was a light damp patch on her knickers. She slipped her hand inside the waistband and felt how wet she still was, even though it was hours since they’d left the study. She slowly started rubbing herself and leaned back against the wall, biting her lip to stifle a moan, and allowing the tingling feeling to build in her nether regions as she continued to massage her clit. She was just about to insert a finger inside when she was startled by someone noisily entering the changing cubicle next to her.
She mentally cursed whoever it was for interrupting her, and grumpily put her own clothes back on and left the changing area. She decided she’d go with the last dress she’d tried on. The first was her favourite but she felt it was probably a bit much for a dinner with her father, plus it didn’t really suit the cold weather. She headed back outside.
“What did you get?” asked Jon.
“You’ll have to wait and see,” Emma replied with a smile. “It can be a surprise for later.”
“Very mysterious,” replied Jon. He glanced at his watch. “I think we should maybe head back to the hotel; it’s getting on a bit and after the heat in that room this morning I think I could do with a shower.”
“Sure,” Emma agreed. “I’m feeling pretty tired if I’m honest, putting my feet up for an hour or so would be nice.”
They headed back to the hotel, Emma flopping onto her bed as soon as they got into their twin room.
“Do you want to use the bathroom before I have a shower?” asked Jon
“Nah I’m good,” replied Emma. “You go ahead.”
Jon grabbed a change of clothes from his suitcase before heading into the bathroom and locking the door behind him. He stripped off and turned the shower on, testing the temperature before climbing in and letting the warm water engulf his body. It felt good to wash off the clammy feeling he’d had from sitting in that baking hot room. What a weird study, he thought, as he felt his penis still slightly engorged from the experience. He’d stopped actively thinking about the videos, but his body clearly hadn’t moved on and forgotten it.
As he stood in the shower, he gave his half-erect cock a few strokes and contemplated jacking off while he had the privacy of the bathroom. Would Emma get suspicious if he took too long in the shower? He felt pent up enough that he doubted it would take that long, but he was still wary. He sighed as he decided against it. Maybe he could head back to the hotel for a private moment tomorrow if Emma wanted to do any more shopping.
