Rapid Recovery and Reduced Refractory

You needed a cold shower. You realised your body was still adapting to the semen volume enhancement serum and your production was increasing while your refractory periods were growing ever shorter. Perhaps this should have worried you… the scientist in you knew that you should be wary of this development… but the pervert in you couldn’t be more thrilled. All you could think about was how many more loads of cum you could give to your addicted aunt. Your erection felt searing hot, like it should be giving off steam under the cold stream of the shower. After five more minutes standing there you turned off the water, got dry and decided to step back outside in just a towel. It had only been 2 hours since your aunt’s last dose but you figured she wouldn’t mind an extra dose… just to cheer her up after your mom left.

You found her reading a book on the couch, looking quite relaxed with her knees folded, one elbow on the armrest. Suddenly it felt awkward to be standing by the couch like this because it seemed to take a moment for the woman to notice you. When she did her eyebrows knitted, her eyes inspecting you from head to toe… to crotch. She licked her lips and pulled her gaze back up to your eyes.

“Y-yes?” she said, shifting a little in her seat as she put a finger between the pages to keep her place in the book. Your towel was quite thin and your erection was clearly visible under the curtain of white material. There was that glimmer in your aunt’s eye because of it, but still you weren’t sure where to start.

“I was wondering if you… uh…” you said, scratching the back of your neck for a moment. “If you could use another… dose. If you-”

“You’re ready again?” she said, her book snapping shut, the bookmark on the armrest ignored. She sat up with interest.

“I am,” you confirmed, smiling sheepishly. “I think the formula is still affecting my recovery and production rate and-”

“I want it,” she cut in, grabbing the towel with both hands. “I need another dose.” She pulled it down without delay and let it fall to rug. She smiled wide seeing your thick rod again and cupped your balls. “Oh you are ready,” she noted, weighting them in her palm, rolling them gently in her fingers. They were heavy and full and you sighed at her touch. She leaned in and kissed your testicles, pressing her lips lovingly to the wrinkled skin then poking her tongue out. You looked down at the lesbian, her eyes shut as she started lapping at your balls… worshipping them and what they contained.

“Holy shit,” you couldn’t help sighing as she wrapped her hand around your shaft while still massaging your nuts in her mouth. She moaned, dropping them from her lips for a moment and you saw that she had a hand down the front of her shorts already.

“You did this to me,” she whispered. You blinked at her but she wasn’t looking at you. She seemed to be glaring at your cock. “You did this to me…” she kiss the side of your shaft, licked up to the crown, sucked at your frenulum until she coaxed the first drops of precum from your piss slit and she sipped it like fresh dew off a leaf. “Your delicious cum… made me this way…”

“Aunt Les… I…” you began, unsure of why she was saying these things but so turned on by her passion you couldn’t really say anything in response.

“John… I’m so wet… I need this cock so bad…” she rasped, her breathy voice warming your stretched skin. “I need your cum… all the time… in my mouth… down my throat… just ...inside me...”

You groaned, her strokes long and firm as she slathered it with her wet tongue. She was panting, getting to her knees, her fingers busy between her thighs when they weren’t pumping your meat. “Give me your cum John, please… all day…” she begged, then wrapped her lips around your head and started sucking. You took this as cue to thrust into her mouth and began to gently work your meat deeper. Her mouth was so wet and warm, her spit spilling past her lips already with how much your cock made her mouth water. She took you harder and as you hit her throat you felt her whole body shudder. She was already climaxing via her own stimulations and your grabbed the back of her hair for more leverage as you fucked her skull.

Her orgasm seemed to be shorter than usual you found her gripping onto your thighs now, her damp fingers digging into your skin as you rammed your rod in and out of her face hole. She started scrabbling for you, reaching up to grab your hands and soon you had your fingers locked together as you thrust into her mouth then finally burst. She vacuumed your semen straight out of you, your release torrenting down her throat with spurt after spurt. Her palms pressed against yours and she arched her back, your balls vibrating on her chin until they were fully spent.

Your cock was withdrawn with a wet slop, still hard, smacking her in the face as she heaved for air. Still so hard but your balls were lighter, felt empty. Your aunt pulled you down into the couch and you fell on top of her, you naked and Leslie in her limited wardrobe. She yanked her shorts down hurriedly and she grabbed your wrist, stuffing it between her legs. Head spinning you felt her kissing your neck with stick lips, her cum-scented breath on your ear. “Make me cum… I need you to make me cum, John,” she said, humping your hand, her pussy searching for your fingers. You managed to clear your head enough to perform the task at hand and curled your fingers into her, earning you are lustful moan from the woman. She still held your wrists and was fucking herself on you, all the while you could feel her thigh bare pressing against your bare cock. Sandwiched between your flesh and hers you winced, still feeling sensitive after cumming so hard down her throat but it was an ache you were relishing. She humped your hand while you humped her leg, and you knew she could feel your veiny thing slipping and sliding against her lower pelvic region. “More fingers,” she demanded to you breathlessly, and you obliged, and by this point was almost four knuckles deep in the woman, stretching her greasy pussy. A few more seconds you grinding against each other in a sort of awkward arrangement on the couch and she came again all over your hand. She writhed, her thigh shaking against your crotch, squeezing the last dregs of fluid out of your cock and up her hip.

Two orgasms done your aunt finally relaxed, letting you have control of your shoulder again and all you could do was flop on top of her like a big sweaty blanket. She giggled against you, kissing your neck and cheek, and when you pushed up to see her face she tasted your lips and searched for your tongue. It was an intimate but calming sort of make out and you both sighed wearily as your lips smeared away from each other and you slid next to her on the cramped couch.

“When can you cum again?” she asked you a barely a minute later. You looked down at your own still bulging erection and your balls hanging sidesaddle thanks to the way you were resting on your hip. You could actually feel them getting fractionally heavier, as if they were balloons being filled by a leaky tap that was almost dribbling into a stream.

“I think… maybe in another two hours,” you estimated, educatedly. Your aunt grinned.

“So after we have lunch… then… we’ll have some fun…” she said. She gave you a quick, biting kiss that left a light sting on your bottom lip but the pain there didn’t last long. “I want to try something…” she said, her eyes getting more serious now which made you quirk and eyebrow.

“Like what?” you wondered. She was staring down at your crotch, lost in thought for a moment. Then, without taking her eyes off of your cock she exhaled greatly.

“Something I’ve never wanted to try before,” she said.
