Dr. Sykora (T+0 days)

“Gretchen, are you free to talk?” Dr. Sykora asked his daughter’s best friend via video chat. “Elyssa’s not with you, is she?”

“No, she’s not. She’s the kitchen. Making sssoup.” Gretchen spoke with the characteristic slowness of someone deeply under the influence of drugs, and the clumsiness of someone whose face had been traumatized by dental surgery. “I threw up and now I need more.”

“How are you doing?” The doctor asked, concerned that the girl may have been prescribed too strong a dose of painkillers.

“I’m okay,” Gretchen replied. Her head rolled around on her neck in a way that suggested she might lose track of it.

Gretchen’s emergency dental surgery hours before had come at an inconvenient time. Her mother had essential business that required her to be away all day, leaving Gretchen in the care of Elyssa, on Elyssa’s seventeenth birthday. Gretchen had chosen to celebrate by sneaking a few swallows from the bottle of vodka she had found two days earlier. The warnings about mixing alcohol with her pain medication had come across much the same as a giant red button labeled “Do not touch” might have to the impish girl. This was her chance to get really truly wasted without breaking any serious rules.

“Ssso what can I do...” Gretchen asked Dr. Sykora, forgetting the rest of the question.

“I’d like your ideas on what to get Elyssa for her birthday,” Dr. Sykora stated. “What does she want?”

“Glad you askedt,” Gretchen said as if beginning a lecture. “She wants cock. Lots and lots of cock. She wants it in her pussy, and in her mouth, and in her BUTT.”

Dr. Sykora smiled to himself. This was not a conversation he would normally have had with the teenager. “I was under the impression that my daughter was already sexually active,” he stated cautiously.

“Oh, she is-s!” Gretchen answered. “Very much so.”

“Then why does she need my help obtaining all this ‘cock’ that you say she so desperately wants?”

“Because she’s got a boyfriend!” Gretchen stated. When the doctor didn’t respond for several seconds, Gretchen decided that perhaps he needed it spelled out for him. “Ssee, if it were me - if I could get guys like Elyssa can - I’d be doing two or three of them at a time all the time. But Elyssssa’s not like that. She’s mongomonous. Mon ... Mono ... Mon-o-ga-mous. She wouldn’t want to cheat on Ivan by humping a lot of other guys at the same time.”

“I see,” Dr. Sykora replied. “But what exactly are you suggesting I do to help?”

“I think you should give Ivan an extra cock,” Gretchen explained. “No, two. One right next to the original one, and one on his chin. I think Elyssa would like that. But not right now. Ivan is at the state fencing championship right now, and they might disqualify him if he has a cock on his chin. Because the mask won’t fit right.”

Gretchen had a healthy respect for Dr. Sykora’s scientific prowess. Brilliant, driven, and unbound by pedestrian ethics, he had trail-blazed a number of fields that his lesser peers might have reluctantly called “mad science”. Still, there were limits, and he was amused by the girl’s faith in him.

“Thank you, Gretchen,” he told her. “I will consider your advice on how to help my sixteen year old daughter’s boyfriend despoil her in fresh ways.”

“Thev-seventeen,” Gretchen corrected. “She’s seventeen today.”

“Ah, yes, of course,” he acknowledged.

Ivan (T+20 days)

Ivan was in his bedroom folding his laundry when he heard the familiar hum. A shimmering pillar of purple darkness appeared, and out of it fell an inhaler. He smiled as he picked it up and read the note attached, and then put it in the plastic grocery bag holding the other items he had prepared for the day. Bag in hand, he stepped into the purple and found himself in Gretchen’s back yard.

“Happy birthday, Elyssa!” Ivan said after he let himself into the house.

“Ivan!” Elyssa shouted gleefully as she sprinted into his arms. In that brief moment of action, Ivan marveled at his girlfriend, as he often did, and how she could be so remarkable in so many ways. With three steps she had shown herself to be the epitome of strength, grace, and femininity - and that was just scratching the surface of her superlative qualities.

“What are you doing here?” She asked after a kiss. “I thought you were off at the competition.”

“Your dad arranged for me to be here, I think,” he told her. “I’m not exactly sure - he’s kinda mysterious.”

“That he is,” Elyssa said, and kissed Ivan’s face indiscriminately.

“Hey Gretch. Howya doing?” Ivan asked, finally turning his attention to the miserable-looking girl wearing pajamas and holding a bag of ice to her face.

“My faceth has a hundred hammers in it trying to get out,” the redhead slurred woefully.

“That sucks, man,” Ivan said. “Hey, would it be cool if we left you alone for a little while?” He tried very hard to sound sympathetic, but even in her groggy state Gretchen could see the animal eagerness that motivated him.

“Mmm-hmm,” Gretchen said. “You two go frolic and ga-vort. I’ve got YouTube.”

“Yell if you need me for anything, ‘kay? I’ll come right down!” Elyssa said as Ivan lead her by the hand up the stairs.

Once inside Gretchen’s mom’s bedroom, things progressed as they often do when a teenage boy and girl are alone together. There was tickling and laughter, wrestling and squealing, and all the while, pieces of clothing were being cast away without concern.

The child’s play ended suddenly when Elyssa, naked, sat back in the easy chair and spread her strong sleek legs lewdly. Ivan accepted the invitation silently and approached her, his cock leaking pre-come with anticipation. His knees joined her on the chair and he leaned over her. His lips settled above her ear and whispered, “Happy birthday,” again as his erection slid inside her welcoming flesh.

Ivan groaned as he worked his way deep into her. “How are you this tight?” He wondered aloud.

“Lots of Kegel exercises,” Elyssa said playfully. She pulled at his back, urging him thrust into her harder. “But it helps that you’re so big,” she added with a twinkle in her eye.

Both of the teens worked their bodies into each other’s in a well-practiced fashion, both moaning softly. Ivan’s body was rubbing Elyssa’s clitoris in a surprisingly potent way, inspiring her to call out. Gretchen was the only one home and she wouldn’t mind. “Ivan, fuck! Oh god what you’re doing to me!” she exclaimed.

Ivan kept grinding exactly the same way, knowing that together they had stumbled into the perfect configuration. He knew that he wouldn’t be able to hold back much longer either, excited as he was by the smell of her hair, the passion of her moans, and the strength of her thighs squeezing him, outside and in. That was okay - he didn’t need to set a record right now, as long as Elyssa came.

She did come, crying out with the vulgar innocence of a teenage girl, her hips shaking beneath her lover as her body engaged autopilot and flooded her nervous system with bliss. Ivan couldn’t last against the onslaught of contractions and punctuated gasps that his girlfriend’s body was producing. Some switch in his body was tripped and he felt the exotic relief of climax as he gushed fluids into her pussy.

Not long after, the two teens were on the bed: Elyssa lying face down, and Ivan leisurely rubbing her back.

“So how is it you’re here, lover?” The hard-bodied brunette asked. “I thought you’d gone for another two days.”

“I’m not 100% sure, but I think your dad hooked me up with a ride.” Ivan answered.

Elyssa chuckled. “I bet he didn’t think we’d be doing this with the time together he gave us!”

“You know,” Ivan answered, “I think he kinda did.”

Elyssa shot Ivan a questioning glance, but his playful smile told her to be patient.

Ivan’s hand had strayed from Elyssa’s back to her butt, and now it was slipping between her cheeks and brushing against her asshole.

“What do you think you’re doing?” Elyssa asked with coy protest.

“I happen to know that this is the day you give up your brown cherry,” Ivan stated confidently.

“Oh you do, do you?” Elyssa replied with mock defiance. She offered no resistance, however, when he retrieved a bottle of lubricant and used it to push his finger into her butt.

Ivan and Elyssa were silent for the next three minutes while Ivan methodically fingered her asshole. Even as Elyssa bit her lip and clenched her thighs to mask her orgasm, they were silent. She failed to keep her secret; the smile on Ivan’s face demonstrated pride in making his girlfriend come.

“Okay, I’m ready. Stick it in me,” Elyssa instructed. “Fuck my ass.”

“Soon,” Ivan replied with unprecedented patience.

Ivan (T+6 days)

Ivan was in his bedroom, reading Macbeth, when the room grew dark. In a matter of seconds, the darkness coalesced into a shimmering, humming, purple-black pillar. An unmarked pharmacy pill bottle fell out of the darkness with a note taped to it. “Take with water. Wait 15 minutes. Step into the rift,” it said.

Ordinarily Ivan would have found this to be alarming, but in the week since Elyssa’s birthday she had repeatedly hinted that something strange would be happening to him soon. In the eight weeks that they had been dating, he had learned that Elyssa had access to all sorts of her father’s fantastic inventions, so he wasn’t worried. After swallowing the pills and waiting twelve minutes, Ivan stepped into the blackness and found himself in a familiar back yard. Spying Gretchen on the couch inside, he let himself in.

“Hey Gretchen,” Ivan said to the groggy redhead holding a bag of ice to her jaw while flipping channels on the TV remote.

“Did you have to go in for more surgery?” Ivan asked upon seeing the ice and the swelling in her face.

“Uh, yeah?” Gretchen replied, confused by the “more” part of his question.

“That sucks,” he said. “Hey, is Elyssa here by any chance?”

Gretchen pointed to the ceiling. “I thought she was upsthairs with you,” she said.

“Okay...,” Ivan said. “I’m just going to go look for her.”

Gretchen nodded and shrugged.

In the bedroom, Ivan found Elyssa naked on the bed, with a naked boy sitting next to her. The naked boy looked exactly like him.

“Ah, cool, you’re here,” the Ivan from the bed said, while Elyssa and the new Ivan tried to figure out what was going on. The naked Ivan stood up, withdrew a black marker from his plastic bag, and drew a large “1” on each of the newcomer’s upper arms. After that, he similarly drew a “3” on each of his own.

“She was just asking for you to fuck her up the ass,” Ivan 3 explained, pointing to Elyssa and Ivan 1 in turn.

“Are you a clone?” Ivan 1 asked. Elyssa had sat up by now and was watching the two Ivans with great interest.

“No, man, I’m you from the future,” Ivan 3 explained.

“That’s not...” Ivan 1 began to protest.

Elyssa, on the other hand, bounded toward Ivan 1 and whispered in his ear, like a child excited to play with a new toy.

“Pufferfish Tango,” Ivan 3 said, repeating aloud the code phrase that Elyssa had whispered in his ear two weeks before, from his perspective.

Ivan 1 remained silent, unsure how to react to the situation. Elyssa grinned and fidgeted, finally saying, “C’mon!” before starting to undress her new lover.

“You’re from the future too, by the way,” Ivan 3 told Ivan 1. “Today is Elyssa’s birthday.”

As strange as the situation was, Elyssa’s nakedness and excitement as she undressed him were too much to be ignored, so Ivan 1 decided to forgo any other questions at the time. Also not to be ignored, Ivan 1 found that he had a raging hard-on, more desperate than ever to fuck.

Three naked bodies wrestled and kissed, but only briefly.

“Elyssa - I can’t wait any more,” Ivan 1 said. “I need to be inside you, now. Please?” Ivan 1’s face was filled with anguish. Elyssa looked to Ivan 3 for an explanation.

“It’s the pills,” he explained. “I think your dad gave him some sort of super Viagra or something.”

Even as she lay back and spread her legs to accommodate her aching boyfriend, Elyssa looked at Ivan 3 curiously. “But you’re not on it?”

“No, I’ve got this,” Ivan 3 said, pulling the inhaler from his bag. “It gives me a recharge on demand.

“Interesting,” Elyssa remarked as Ivan 1 climbed on top of her and entered her pussy.

A minute later Ivan 1’s discomfort was gone, replaced by groaning bliss.

“Mmm, this is wonderful,” Elyssa told her lover. Ivan 3 was sitting on the bed next to her, holding and stroking her hand. “But he kinda got me excited about the idea of trying anal,” she added with a head tilt toward Ivan 3. “Help a girl out and switch?”

Elyssa remained on her back but swung her legs up by her head. Ivan 3 held her ankles and peppered her face with kisses while Ivan 1 knelt before her, applying lube everywhere and gently pushing his cock into her butt.

“Mmph?!” Elyssa groaned as the tip of his spear penetrated the limber girl. Ivan 1 looked at her face for confirmation and was met by an enormous smile. She groaned as her body reluctantly accepted more and more of his cock as he cautiously rocked his hips into her.

“Hhh-oh!” Elyssa’s moan rang out.

“It’s ... so tight. Are you sure I’m not hurting you?” Ivan 1 asked.

Elyssa answered between gasps. “Kinda, but it feels so good! Give it to me. Do it for real.”

Ivan 1 complied. Still kneeling, he grabbed her hips and relaxed into a pattern of deep thrusts into the girl’s bowels. She moaned like a fire truck. Ivan 3, meanwhile, tucked Elyssa’s close ankle into his arm pit so that his hand was free to massage her breasts.

Minutes passed.

“Coming!” Elyssa announced. She dug her nails into Ivan 3’s arm. Ivan 1 watched while her empty vagina winked its spasms at him and his girlfriend gasped.

Ivan 1 held back his own orgasm. He wanted to give Elyssa as much satisfaction as he possibly could. His hand wandered to her bush, and then down across the lips of her pussy. At the same time, Ivan 3 let go of her legs and gave the full attention of his fingers to Elyssa’s nipples. She shrieked.

“Way. Too. Fucking. Much!” She exclaimed. Both boys withdrew their hands, until Elyssa chastised them, “Don’t stop!”

Elyssa’s now free legs gripped the boy between them, giving her purchase to smash their bodies together even harder. Ivan 3 moved his hands to her face and kissed her, stifling the cries that accompanied her new orgasm.

“I think you’re breaking my dick,” Ivan 1 said, without any real alarm, as Elyssa’s asshole clenched in waves. He couldn’t take it any more. He gave in, and released, and felt his semen flowing out of him in jet blasts.

The three lovers collapsed on the bed together, a tangle of arms and legs, panting.

Ivan (T+13 days)

When Ivan 2 let himself in to Gretchen’s house, he was surprised to see Elyssa sitting on the couch next to Gretchen. This wasn’t birthday-Elyssa, he reminded himself: this was the Elyssa from the future who would be joining them later. The Elyssa he would be meeting in the bedroom had hair down to her waist, but this one’s hair was barely past her shoulders and was adorned with a blue streak.

“Hey!” Elyssa 2 said. She withdrew two bottles of water from her shopping bag and threw them to him, and then pointed her thumb toward the stairs. Ivan 2 followed his instructions and joined the others in the master bedroom.

“Hey baby! Happy birthday, again!” Ivan 2 said to Elyssa 1. Ivan 3 quickly wrote a “2” on each of his arms.

“Jeez, how many of you are there going to be?” Elyssa 1 asked.

“Just three - if you think you can handle us all,” Ivan 2 said with a smirk.

“I’ll find a way,” Elyssa 1 answered with a twinkle in her eye.

“Good,” Ivan 1 said, emerging from the bathroom after having showered to clean his dick. “I don’t know what was in those pills, but I need to go again, ASAP.” The towel around his waist was misshapen by his erection.

Elyssa 1 shook her head. “I love you baby, but my ass is literally still throbbing from the pounding you just gave me. I’m going to need a few minutes.”

“Fuck. Okay,” Ivan 1 said with obvious disappointment. He grabbed his package through the towel and gave it a few squeezes.

“C’mon man. Have a seat. I’ll take care of you,” Ivan 3 said to Ivan 1, gesturing at the easy chair.

“I’m not going to do another guy,” Ivan 1 said.

“But it’s not another guy,” Elyssa was quick to volunteer, “it’s you. It’s really no different than masturbation. I’d actually kinda like to see it.”

“No, I’m not into that,” Ivan 1 protested.

“Dude, you literally can’t lie to us,” Ivan 2 argued. “You’ve always been curious what it’s like to suck a dick. Well this is your chance to do it without it being awkward. Or, well, his chance,” He corrected himself, pointing at Ivan 3.

Everyone could see the hesitation on Ivan 1’s face.

“It’s already happened. You’ve already done it, and you liked it,” Ivan 3 explained. “I said I liked it too. Or, I will.”

“What happens if I don’t go along this time?” Ivan 1 asked. “That’s a paradox, right?”

Elyssa 1’s face showed deep thought as she tried to fit together the pieces of the time-travel puzzle she had learned so far, but Ivan 2 answered first in a very different way. “I don’t know what happens if you try to avoid your fate, or whatever. Maybe the universe implodes. Maybe nothing happens. But I do know that it’s Elyssa’s birthday and seeing you blow yourself will make her happy, so that’s good enough for me.” Ivan 3 nodded.
