Amber helped Jake to wrap in a bathrobe and give him as much decency as possible. She tied the garment around his hips, but his belly was so big it poked out, opening the robe over his cleavage. His breasts were leaking but there was no time to take care of that.
After walking Jake out of the house and installing him in the car, Amber ran to the neighbours to ask them to look after the triplets and Eliza. Fortunately they were home and didn't mind, considering the urgency of the situation.
Jake was overwhelmed by a lot of conflicting sensations as he waited in the car. On one hand, the contractions were somewhat unpleasant, but on the other his beautiful belly was bigger than ever. A couple of bystanders of their residential street were glancing at the car, whispering to each other about Jake's very pregnant belly and exposed breasts. The situation was giving him such a rush of endorphins, adrenaline and dopamine that he was high as a kite.
Amber returned quickly, and a short drive later they arrived at the clinic. Jake was hurried to Dr. Thomson's department. Amber followed along and was invited into the room during delivery, which went very smoothly as it wasn't Jake's first. Dr. Thomson examined each of the baby girls to confirm they were indeed healthy.
"Four! That's incredible." Dr. Thomson noted enthusiastically. "I guess the experimental treatment for Jake has made him quite fertile. That's good; this is exactly the sort of encouraging results we want. I will write him a check that he can pick up when he leaves the clinic tonight.
Until then, Jake would recover in one of the bedroom the fertility department allocated for expecting couples.
"If you'd like to come with me now," Dr. Thomson asked Amber when it was time for her trial. "We have two participants for this study. One will be inseminated by nurse Jenn, so we will need you to procure semen in a tube. The other participants is receptive for in-person insemination, and we have a room prepared with privacy in mind, since this is such a unique procedure. We want to maximize comfort for all involved and make sure consent is respected every step along the way."
"What if I can't... like, cum enough?" Amber asked, a little anxious about having to perform in rapid successions.
"We're confident that with the treatment you've followed it should work out fine, but just in case you can take this, which is a derivative of Viagra,"Dr. Thomson said as she gave her two pills and a glass of water, as well as a tube. "You can use the bathroom and hand the tube to nurse Jenn when you're finished, after which I will take you to the private insemination room.
Amber entered the bathroom, which was quite spacious. She took a minute to put her mind at ease after all the medical talk, and swallowed both pills. Now alone with her thoughts, she could allow herself to feel the arousal she had repressed since finding her husband about to pop in the bathroom. She loved the look of the bystanders in the street when she was helping Jake into the car... She wondered if anyybody knew she had put those babies into him.
She looked down on her denim mini shorts, the same outfit she wore the day before. She didn't have the time to pick something else before leaving for the clinic. Once again a bulge was growing on the front of her shorts. She unzipped them, pulling out her hard-on. She was quite the grower, going from a healthy but delicate looking soft member to quite the hefty piece of meat when she was rock hard.
Amber closed her eyes and rubbed her length sensually, thinking sexy thoughts. She hoped the fertility treatment worked on her too; her sex drive at least was through the roof. She couldn't wait to make Jake moan again; she loved unloading her juices into him and making him lose control. He was quite unhinged with the whole pregnancy kink, and she loved him all the more for it.
She was starting to lubricate a lot and rubed her delicate fingers over her fat mushroom head, smearing her pre around. The tube's opening was relatively small and she hoped she wasn't going to make a mess of the whole thing. She remembered there was someone waiting for her in the other room. Waiting for her to impregnate them. She hadn't put her dick in anyone but her husband in a long time. Their marriage was pretty open, but with Eliza and then the triplets, it hadn't left a lot of time for anybody else for a while.
Of course the situation was a little different today. The person waiting wasn't a lover, it was just another person on the trial trying to get pregnant. Her cock throbbed at the thought again. The thought of filling someon's belly with her seed, making their growing belly full of babies.
God she did love that, didn't she. Making Jake grow huge. Her large dick was leaking profusely now and she was jerking faster and faster. Whoever her "sample" would go to, she hoped her semen would give them as many babies as they wished for.
After only a few minutes, she felt herself come close to climax, and she placed the tube in position to receive her ejaculate. Eventually her ballsack tightened and shot her load, which came in three or four bursts of diminishing strength. With a trembling hand she closed the tube and wiped herself with tissues. Now that was job number one done. On to "in person insemination", as Dr. Thomson called it.
There was just one problem.
Amber had not lost one inch of her erection: her monster was still rock hard and refusing to go down. She wondered if taking both pills at once had been the right move, or if one was intended for each session, after all. It was too late anyway.
She tried to direct her length on the side along one hip and pull up her mini-shorts, but it was a struggle to zip up and close them completely. There was still a huge bulge showing through the denim outlining very clearly her hard-on.
Minutes passed, and Amber felt it just couldn't be helped. She walked out of the bathroom with the sample in one hand, her other hand over the front of her shorts.
"Hm, excuse me, nurse Jenn...?" she asked, trying to sound as normal as possible. Nurse Jenn, who had been waiting for her, picked up the sample. Amber knew she would probably use it with the strap-on contraption Jake mentioned for his first pregnancy. That is how Eliza came to be.
"Please, follow me," Amber heard Dr. Thomson call, indicating a door further down the hall. Amber tried to hide her erection as best as she could, but she had really picked the wrong outfit today. As she walked, her length naturally redirected itself more upwards, and she only noticed when entering the insemination bedroom that her member was exposed past the waistband.
"I will leave you with Ryan here. The procedure elaborated with nurse Jenn didn't work out in this case, but we hope this new trial will be a success. I will leave you two to it." Dr. Thomson left the room and closed the door quietly.
Ryan was sitting on the bed in an hospital gown. Amber cleared her throat, still trying to cover the front of her mini-shorts with her hands. "Sorry, it's the meds," she laughed awkwardly. Ryan smiled and shrugged.
"We don't have to talk if it makes things easier. I'll remove the hospital gown if that's okay?" he said.
Amber nodded, and approached him as he laid on the bed on his back. He seemed a little younger than Jake. The procedure obviously didn't work as well on him, though his body was quite androgynous, but he didn't have much breasts. His pussy looked totally normal, though his clitoris was appearant and on the bigger side.
"May I?" Amber asked. She kneeled in front of his open legs at the edge of the bed and began licking him gently. He almost jumped as though he didn't expect any preliminaries, but quickly relaxed and began breathing louder as she worked her magic on his clit. It was also a grower and swelled as big as a thumb, like a vestigial penis. Ryan's folds quickly sipped with juices, which is exactly what Amber wanted.
Amber pulled down on her shorts, revealing her still erect monster; she also picked up the bottle of lubricant that was on the nearby table to lather her length with it, then positioned herself to enter Ryan.
"Ready?" she simply asked. Ryan nodded.
She pushed her glans past Ryan's lips, perfectly lubricated. She heard Ryan pants a little.
"Is this okay?" Amber asked nervously.
"Yes, it's perfect, keep going," Ryan reassured her.
She pressed forward. Ryan was smaller and felt tighter than her husband. It wasn't uncomfortable, just a little more intense. Amber held Ryan by the hips and gently pulled him closer, until she felt her ballsack touch him. She was also right against his engorged clit. Ryan let out a moan, and she pulled back a little, making sure the lube was smeared all the way, then closed the distance again. The two bodies met with a wet noise, and Ryan moaned a little louder.
Amber picked up the pace, trying to keep her cool and look as professional as possible, if there was such a thing in this situation. At first she was a little desensitise from her earlier session, but now the wave of pleasure were slowly coming back to her. Looking down on Ryan, she saw that he was looking at her.
"Can you... can you remove your top?" Ryan asked her hesitantly.
"Sure thing," Amber replied. That's only fair, considering she could see all of him.
She threw her loose crop top aside, revealing her perfect breasts. She didn't have the time to wear a bra this morning with Jake's situation either. Amber pushed into Ryan once more, her breasts swaying with her movements. She watched as Ryan's clitoris grew harder against her groin. He liked that.
Amber resumed the back and forth hammering into Ryan, who was relaxing and moaning louder by the minute. She too was starting to loose control, her hefty member throbbing into him. She reached with one hand and caressed his side up to one breast. He was an A cup or a small B at most. She flicked his erect nipple with a thumb, and she felt his walls spasm in pleasure around her hard cock. It sent delicious shivers up her cock and spine.
She quickened the pace once more, hammering harder and harder into Ryan. The two of them were panting and moaning loudly now. He was grabbing at the bedsheet, on the verge of climax. Amber held him by the hips as she felt herself come, bucking into him. Ryan arched his back as the orgasm took over, an effeminate moan echoing in the room.
She cummed profusely into him, bursts of semen exploding in rapid successions as his womb contracted to suction the fluids. The fertility cocktails in their bodies had taken effect, and a massive amount of sperm swam to two eggs Ryan had released. Both got fertilized and each split into a perfect replica of the other, totalling four embryos - two girls and two boys, soon growing into Ryan's womb.
Amber caught her breathe and slowly pulled out. A sticky rope of fluids stretched between her erect dock and Ryan's pussy, and excess cum oozing out of him. She grabbed a wipe to clean herself.
"I hope that did the job," she said to break the awkward silence. Ryan laughed a little.
He tried to prop himself up on his elbow but was still weak and a little shaky from his orgasm. He was also red as a beet.
"Yes, I think I'll be okay." He had a strange expression on his face, as if he just had a religious experience.
Amber's erection was still not ready to die down completely, and once again she struggled to close her mini shorts over it, exciting the insemination room with an awkward shuffle while trying to conceal her bulge. She hoped the effects of the pills would pass now...
