Test Results

Your aunt found you about half an hour later frowning at your laptop screen, the device connected to a bunch of complicated looking peripherals housing tubes and chemical sensors that were used to check various advanced properties of your semen.

“Is everything okay?” she asked you, appearing by your side and snapping you out of your analysis. You looked over and saw a glowing naked woman, which was just as well really since you were still naked. Still hard too. There was a look of concern on her face and you realised it was a reflection of yours. You relaxed and gave her a smile.

“No yeah, everything’s fine,” you said truthfully. Your knitted eyebrows had just been you concentrating and thinking. “My semen is… perfectly health. Perfectly normal like it was before the injection...only I’ve got a massively increased volume. The sperm count is normal, maybe slightly elevated but it’s probably again just because of the volume… it’s really quite remarkable.”

Leslie put an arm around your shoulder and the feeling of her smooth skin on yours had an immediate reaction for your cock, hardening it more. The side of her breast was pressed against your arm as she looked at the screen.

“So all that cum… is just normal, real cum,” she said. “I think I could tell by the taste.” She smirked and it gave you a small laugh. “Imagine if you hadn’t been wearing that condom though,” she added jokingly. “Imagine if you had shot all of that cum inside me instead.”

You blinked at the screen. Her tone had been casual, but with her right by your ear it was intensely intimate and hinted at something more.

“Yeah… imagine…” you said, giving a half hearted chuckled which she returned, but something else remained lingering in the air as she pulled away from you. You cleared your throat and rubbed your eyelids for a second. “We’ll need to be more careful though,” you continued, scratching your half-filled balls absently. “If we do … that again.”

“What if we did something else…” you heard her say from across the kitchen. You looked over to her standing in front of the open fridge, eyes closed as she let the refrigerated air cool her naked body. You swear you saw those delicious nipples of her stiffen and extend.

“Something else?” you wondered, watching her cool herself. Her thoughts were getting her heated.

“Like… I’ve been doing some reading,” she went on, opening the freezer compartment at the top. There was a short rattle of the icetray and you saw her pick a small cube out with her fingers. “About different ways a dose can be administered.”

Your eyes went wide since, being an expert in the field, you knew exactly what different ways there were. Shutting the fridge door your aunt sauntered over to you, running the quickly melting ice cube along her collarbone for some reason. She stood in front of you and casually sucked on the ice cube, as if this was a normal way to cool down. Droplets of water had streaked down to skim across the curve of her breasts. Her tits were right in front of your face and suddenly felt very thirsty. You tore your eyes away from her mouthwatering nipples.

“What do you mean?” you asked her, playing dumb momentarily, but you were already a bit dumbstruck anyway.

“What I mean is… you could try giving me my dose... anally?” she said, a hint of uncertainty in her voice but her eyes locked onto yours. She wasn’t joking. You swallowed and felt light headed from the sudden rush of blood to your cock.

“Rectally,” you corrected her. “That would be rectal... administration…” You could hardly believe your mouth.

“Right… rectally… in my rectum…” she said, sounding wistful. “It’s more… effective isn’t it?” There was a slight tremor of excitement in her voice that you noticed and you had to take a slower breath to calm your own.

“Well… it depends. The body tends to absorb rectally administered medications more rapidly through the blood vessels in the rect…” you began, then stopped, seeing your aunt’s pursed lips and scrunched nose. “It’s absorbed faster. The effects of satiation also peak higher and in a shorter time, but that also means a shorter duration in repletion than taking it orally.”

“I see…” said your aunt, absorbing the information as quickly as… well, y’know. “So … should we try it then?” she asked you, leaning closer to your face with a grin. “It might be… safer.”

Blinking at her you couldn’t think of any reason to refuse her suggestion or dispute her idea at all.

“You want me to… you want… you…” you stammered, your cock thickening more, bloodflow barely going anywhere else now.

“I want you to … stick it in my ass,” she said, finishing the thought. “Yes. And give me your load… rectally.” Leslie was starting to sound mildly breathless herself. You winced slightly, feeling a momentary discomfort in the groin then the sensation of your balls… lowering. Any pain disappeared and then all you could feel were your refreshed testicles. They were heavy again, full of semen. It had only been an hour. Your aunt looked down at your crotch and raised her eyebrows. “What? Are you… ready to go again? So fast?” she said, her smile wide. You nodded, looking down at your engorged cock.

“Yeah I guess… arousal helps increase recovery and replenishment…” you hypothesized with uncertainty. You probably would need to run more tests..

“Well I’m almost ready,” said your aunt, her hand snaking up your lap and grasping onto the incredible cock. “Let’s get me the rest of the way.” Through her firm grip you could feel your meat pulsing like a faint heartbeat. She pulled you to your feet with it and lead you back to the bedroom.
