Jeff had been dreading Tuesday since last week. Even though the days leading up to it dragged on, it still seemed to arrive too soon.
“Don’t wait up tonight,” Lana said that morning. “This design session is going to be intense. We might not finish until very late.”
“Intense? More intense than the research sessions?” he asked, though part of him didn’t want to know.
“They want to expand the Slutlana product line. Make it more ... comprehensive.” She shrugged it off. “I don’t know what they mean, but I guess I’ll find out today.”
Jeff watched her moving through the apartment as she got ready, catching a glimpse of some fancy red lingerie under her skirt that he didn’t recognize.
“What are you wearing under that? Is that new?” he asked, trying to hide his nervousness.
“I really don’t have time for twenty questions, Jeff. I’m running late. I’ll text you when I’m done.”
“When do you think that’ll be?”
She paused. “Honestly? I have no idea. This might go pretty long.”
The door clicked shut behind her, leaving Jeff alone. He could have sworn he heard crickets. His imagination was already getting away from him.
“It will be fine, she knows it went too far last time,” he told himself repeatedly.
Jeff spent another day unable to concentrate on anything. His boss came by his desk to ask what the hell was wrong with him. He attempted to look busy, but he was checking his phone every few minutes when his mind drifted to what Lana might be doing.
He’d completely forgotten to eat lunch. By two o’clock, he’d had enough and decided to go home sick, which wasn’t a stretch by that point.
He arrived home and immediately poured himself his first of many drinks. He’d been drinking steadily all day, keeping just enough alcohol running through his veins to keep the edge off without getting wasted.
Nine o’clock came and went. Then ten. Then eleven. By midnight, he started to slip and ended up polishing off the rest of his whiskey bottle in one go before opening another.
Jeff opened his eyes to Lana standing over him, tapping her foot as he lay on the kitchen floor with the morning sun on his face. He felt like he had a jackhammer inside his head.
“What are you doing, Jeff?” she said accusingly.
He looked up, trying to remember where the hell he was.
“Shit...” he said, rubbing his head.
He glanced up Lana’s skirt, noticing the red lace panties he saw yesterday were gone, replaced with nothing. Everything came flooding back in an instant: Siren’s Call, Slutlana, the R&D session.
He sat up in a panic, sending the jackhammer in his head into overdrive. He groaned.
“How did it go?” he asked, trying not to sound like he’d just woken up on the floor after a night of binge drinking.
“It went pretty long. But it looks like you had a fun night in my absence,” she said, glaring at him with contempt.
Lana headed for the fridge and grabbed a bottle of water, drinking it like she’d been lost in the desert. “But it was productive. Really productive, actually.”
She took another long drink. “I really need a shower,” she said as she walked toward the bedroom.
Jeff struggled to his feet, fighting through his body’s stern warning to stay the fuck down.
“Wait, Lana!” He chased after her, crashing into the door frame. “FUCK!”
“Jesus Jeff, are you okay? Sit down,” she said, grabbing his arm and helping him to the bed.
“Lana...” he tried to catch his breath. “Tell me what happened last night.”
“You are a mess. Why don’t you get yourself cleaned up, for God’s sake?”
“I ... yeah, okay...” he felt like his body was shutting down.
“Maybe we both need a shower...” she said with real concern.
Lana helped him stand and started to undress him, and herself, before leading him to the shower.
The hot water felt like salvation in his hungover state.
“That’s good...” he moaned as the water ran over his face, starting to fully come to.
He glanced at Lana’s naked body standing in front of him, prompting his dick to swell despite his hangover.
Lana looked down as his cock started to point toward her. “Oh for God’s sake Jeff, really?”
He shrugged. “Do you wanna...”
She interrupted. “Did you not hear me say I’m tired? Do you ever listen?” she scolded.
“Okay, okay ... I just ... can you tell me what happened yesterday? Why were you gone all night?”
She exhaled deeply as she started to wash her hair. “Fine, they’re working on the new design, and it’s ... ambitious,” she said. “Much more sophisticated than version one.”
“Sophisticated how?”
“Dual functionality. It’s not just a pussy anymore.” She continued scrubbing her head, occasionally picking out a white clump. “They want to create a complete experience. Pussy and butthole, with heating and realistic muscle movement.”
Jeff held his hand on the shower wall to hold himself up, and asked, “realistic muscle movement? What ... what does that mean?”
“The engineering is actually super impressive. They can make it like the real thing! It can move, feel warm, and react to stimulation.” She rinsed the shampoo from her hair. “They really outdid themselves this time.”
“And they needed you to help design this, because?”
Lana opened her mouth to let in some water from the shower head before swishing it around and spitting it out.
“They’re trying to make it realistic. They have to know how the real thing acts to copy it, obviously,” she said, rolling her eyes.
Jeff’s dick was still growing harder, and she noticed.
“Is that thing going to go down or what?” she said, grabbing hold of it as she shook her head.
“I ... I don’t know,” he said, trying to maintain composure as she gripped it.
“Ugh ... fine,” she said, rolling her eyes.
She moved closer to him until her tits pushed up against him and began to run his swollen head up and down her slit, making him moan. His hands gripped her hips almost involuntarily.
“Anyway, they took several molds, except it was my pussy and butthole this time. But it was basically the same procedure as before.”
Jeff couldn’t help picturing it. Just like those photos on her tablet, but worse somehow.
“That was the easy part, data capture took much longer, which is what we were doing most of the day. They needed real biological data, in different scenarios,” she said as she continued to rub his throbbing cock up and down her already slick pussy.
“What does that mean? What biological data?” he asked, unable to hide the fear creeping into his voice.
“Body temperature, muscle contractions, stuff like that,” she said, her voice becoming breathier.
“They needed real data, to see how my body responded to different ... stimulation.”
“And how did they capture this data? Did they actually use scientific instruments this time?” he said, growing angry as he remembered her previous session.
“Of course. They’re trying to get real data. I had all these sensors hooked up to me. It was kind of crazy!” she smiled at him excitedly.
Jeff felt his shoulders relax slightly. “So it was just ... you masturbating while they took measurements?”
“Well, that was the baseline, yes.” She was working his cock head against her clit more confidently now, and he was getting lost in the sensation.
“Thank god,” he breathed. “I was imagining...” He trailed off as her rhythm increased.
“Imagining what?” she asked, pressing his tip against her entrance.
“I don’t know. Worse things.”
She paused her hand movement and looked at him seriously. “Oh honey. That was just phase one.”
Jeff’s heart sank as she continued. “Once we got the baseline data, we started working through real world scenarios so they could capture how my body responds during actual use.”
“What real world scenarios, Lana?”
“Different kinds. They monitored everything while I played with myself. They wanted me to make myself cum at least three times so they had enough data points.”
She started to move his cock up and down her slit faster now, her lips parting around his head.
“They said the final product is going to feel warm. And when a user gets close to finishing, it will cum too! Or at least it will feel like my real pussy when I cum. Can you believe that?” she beamed.
“Oh god, Lana...” he struggled to hold his composure, nearly losing his balance.
She lifted a leg up to Jeff’s side and slid his cock inside her.
Jeff moaned as she rocked her hips slowly.
“Was that ... was that all they did? For data capture?” he asked hopefully.
“Oh god, no, that was just the baseline.” She slowed her hips even further.
“The real goal is to make it feel real when a user is inside it, so the next step was to capture that data.”
“They just needed me to orgasm when someone was inside me. I had to cum so many times, it was exhausting!”
“Who?” Jeff struggled to get words out.
“Mostly the same guys as last time. Lucky for us, their cocks are different sizes and shapes, which is exactly what we needed.”
She was working Jeff’s cock faster as she remembered. “Sean went first. It was easier to slide that monster cock of his into me this time. But I still felt like I was being split open, in a good way. I couldn’t help but cum as soon as he got it all the way in. But since I came too fast to get any data, he had to keep going and make me cum again.”
She paused, watching Jeff’s reaction. “I did ask the guys not to cum inside me, but honestly, they couldn’t really help it. Sean tried to hold back, but when I came the second time, it made him cum. He ended up filling me with a huge load, which kind of turned me on, so I ended up offering to clean him up with my mouth. It still tastes like strawberry!”
“Then there was Derek, even though he’s not quite as big, there is just something about his cock that feels amazing. He only had to thrust it into me for about five minutes before I was cumming again.”
