The Mounjaro Effect

Thank you for reading my story, I hope that you enjoy it. Love Mica xx, Yorkshire England.

Please note that I am a British female, and I write in British English and vernacular, so for me a fanny is the correct term for female genitalia, a pussy is a pet cat, and the ass is a bum or arse.

I apologise for any typo errors in my story - I edit these myself, and I'm not perfect...

My wife Sally was away for a few days with work and so I was at home alone. Today was a day off, the office was closed for an electronic sweep and so only the tech team were in. It was nice to get a free day off with full pay, but there was always that niggle, what if they found something? Not that I had done anything for them to find, but, what if?

I had face-timed Sally this morning, she had been on her way to her meeting and so we had only managed the most platonic of greetings, no cyber-sex for us sadly, just the usual greetings and 'love you' type. I had a restless night, I always do when Sally is away, and so when I got up I had a shower to try and ease the stresses away.

It was injection day for me, I am diabetic and the doctor recently changed my medication to Mounjaro, a weekly injection that does clever things inside and it has improved my blood sugars immeasurably, quite amazing. Some people take it as a weight loss drug, but I haven't lost any weight since I started, it just improved my bloods.

It has unpleasant side effects though, terrible wind being the worst that I have experienced, usually twenty four hours after the jab it starts and lasts about thirty hours or so. Some people have much worse reactions, I feel quite lucky in that regard. The other side effect I have felt is a massively increased libido, I am horny pretty much twenty four seven.

The shower helps, I stand under the spray, the water hitting my dick at just the right angle is just a pleasure sensation I almost cum just standing still, hands free if you will. I don't ejaculate but have that euphoric feeling that I usually get when I do. Therapy, shower therapy. Thanks Mounjaro, or MoJo as Sally and I call it.

After my shower I dressed in a polo top and shorts, nothing else, I wasn't planning on going anywhere, so fewer clothes meant less laundry, and anyway, it felt great, simply covered up, but not bound up, if you see what I mean. Breakfast was Weetabix and mint tea and after that I sat in the lounge with the laptop and scanned the news and reels. Yes, a relaxing day ahead.

The sun was up and the winter migratory birds had returned and I could hear their chatter through the open windows, and then the alarm calls as neighbourhood cats prowled the gardens looking for prey. Time for another tea. I boiled the kettle and was thinking of perhaps sitting in the conservatory, the sun makes for a pleasantly warm environment, when the front door opened.

It could only be one person, Pam. Pam is Sally's mother and she has a habit of popping around when Sally is away. Sally says she is just being friendly, I suspect it is more a case of checking up on me whilst Sally is away. I turned and looked down the hall.

"Morning Pam, kettle is on, want a coffee or a tea?"

"Morning Drew love, what are you having?"

"I am having mint tea."

"Okay, I'll have the same please."

She walked up the hall and joined me in the kitchen, quick air kiss and then stood back. She was wearing a blue two-piece suit with a pencil skirt halfway up, or down, her thighs and a low-cut matching jacket. It fitted very closely, and you could be forgiven for thinking there was nothing else on beneath, there were no wrinkles or bumps or VPL to be seen.

I made the teas and turned handing her a glass double walled mug with the tea. I like to use the double wall mugs as they are cool to the touch when you hold them, but the tea stays hot for longer and gives the bag more time to brew. A win win situation as far as I am concerned. Sally prefers porcelain.

"Let's go and sit in the conservatory," I said leading the way. In the conservatory I opened the door to the garden, even this early with the sun shining, the conservatory was getting quite warm, the open door let the air regulate a little and brought in the sounds of the birds.

Pam sat on the single cane chair; I sat opposite on the cane sofa. Goodness, good job her pencil skirt kept her knees together, otherwise I would have been able to see her all and sundry, I was glad for loose fitting clothes, and then, on reflection, I would have preferred something a little more restrictive, especially as the blood flowed.

"I wanted to ask you," Pam said, turning and putting her tea onto a side table, "you are on Mounjaro, how are you getting on with it?"

"It has sorted my diabetes, my bloods are just where they should be."

"Okay, did you lose any weight?"

"No, but then, I am not massively overweight, I am carrying perhaps a few pounds too many, but nothing significant."

"No, you do look good. So, I started to take it a couple of weeks ago."

"Why? I didn't realise that you are diabetic like me." I was surprised, she certainly wasn't overweight as far as I could tell, she usually wore quite close-fitting clothes when I saw her, and it would be obvious if she were overweight.

"No, I am not, I don't get it through my doctor, I have just started to add a little weight, and I thought I would get it and try and nip it in the bud, before it gets too much."

"Well, you could have fooled me, you certainly do not look in any way overweight." But then clothes can hide a multitude of sins, she could, for example, be wearing compression garments and I would never know.

She smiled, "well that is a lovely thing to say, thank you, but, well, the scales don't lie."

I shrugged with a smile and took a sip of my tea, finally just cooled enough to drink.

"Did you get, do you have side effects?" Pam asked, shuffling slightly on the seat, her knees still welded together by her tight skirt, the prospects causing slight stirrings where I really didn't want stirrings, not when I had nothing to restrain it.

"Well, yes a few. I guess the wind is the worst. I mean, I am not a person who usually gets wind, but since the MoJo, I am terrible for a couple of days after my Jab, sulphurous burps and awful farts."

"Yes, I read that is one of the side effects, I haven't had that. Anything else?"

"Constipation is an issue for me, although some people get the opposite, diarrhoea, which I suppose is worse, and probably helps with the weight loss, but as I say, I have not dropped any weight at all."

"Okay, anything else, at all, you know, perhaps more personal?"

"Well, yes, I guess, and it is rather personal."

"Well, you can certainly tell me, we are close, we are family. I would be interested to know, it may be the same for me." Pam was looking directly at my face as she spoke, and then she looked down at my crotch, and my dick twitched as she did so, she could not have missed it.

I was unsure, should I really say this, but Sally had mentioned that in the forums other people had reported it, so I decided I would. "Well, it makes me horny, it has done things for my libido, which was not expected."

She smiled, "yes," she said, "exactly, I wasn't expecting that side effect. They do not mention that in the consultation."

Crikey, she had the same side effect, oh well, lucky Bill, my father-in-law, he probably thinks he has gone to heaven. To be honest I never think about parents, or parents in law having sex, obviously they do, I just try not to think about it.

"Yes," Pam continues, "it was most unexpected and not something easily dealt with."

"Oh, I don't know, you and Bill, well, I am sure that you can deal with it between you, not wishing to be indelicate, but Sally sure helps me."

"Well, Bill helps as much as he can, but he, well, it's not as much as I would like."

Wow, talk about oversharing, TMI for sure. "Perhaps he needs some MoJo too then," I said laughing to cover my embarrassment as her disclosure, I don't really need to know my in laws bedroom secrets.

"And what about when Sally is away, like now?" Pam asked, "how do you deal with it?"

"I just deal with it; she is only away for a few days."

"I guess you must masturbate a lot."

"Fucking hell Pam," I said.

"Well, do you?"

"I am not sure this is a conversation that I should be having with my mother in law." I know that my Mum would be outspoken like that, but, well, she is blood, related properly, Pam is simply Sally's mum.

"Oh don't be silly Drew, of course you are, unless you are fucking that blond neighbour of yours. Do you masturbate into a sock or a tissue, or do you let it just go? I am interested."

"Grief Pam, no, I am not fucking anyone, and certainly not Nancy the neighbour." I don't actually know the neighbours name, so I just call her Nancy the neighbour.

"Sally is away for a few more days yet, and you didn't answer my question, sock or free flow," Pam said, her eyes now focussed more and more on my crotch, my hard dick doing nothing to be discrete, tenting my shorts in the most obvious of ways.

"What the hell does it matter, free flow, I've never even heard of using a sock."

"So, you think you can cope then?"

"Yes, I am sure that I'll cope."

"Perhaps we could help each other? You know, you are having side effects, so am I. Your wife isn't here to help, and my husband isn't up to the job."

"Help each other? You mean like a group chat, air our difficulties, that is a bit of an American thing, isn't it?"

"That isn't what I meant," she said, "and I think you know it."

"Well, what do you mean?" I asked, "because I don't see how we could help each other," well, only in my wildest of dreams and I really doubted she meant what she could mean, that would be ludicrous.

Pam stood up and walked to me, standing in front of me she pulled her skirt up top just below her crotch, I did not look to see if I could see her knickers, normally I would, but she being my mother in law, it felt wrong. She looked me in the eye and then straddled me on the settee, pressing her crotch down onto my hard dick. Oh my. It felt as if her fanny was embracing my dick.

"I don't think..." I started to say.

"You don't need to think," Pam said, "you just need to do. We can help each other, scratch an itch if you will."

"Do what Pam? I shouldn't give you what Bill does." I was sure that this was just a trick to catch me out.

Pam began to undo the buttons on her jacket, and I had been right, as the front parted she had nothing on underneath, no vest, no bra, nothing. She pulled the jacket off and was now crouching on my dick with her breasts free. My dick lurched, she must have felt it the way she was pressing against it.

Her breasts were very similar to Sally's but they sagged a little more. I was pretty sure that she had had a boob job, given her age and the size of her breasts, I would have expected them to sag more. I guess if I held them, I would know. I held them, they felt real, my dick lurched again.

"I can feel that" she said. "Take me upstairs."

"Pam, no, I can't do that, that is wrong, you are Sally's Mum," and my dick lurched again, it was saying that yes I could, and that yes, I really should, and to be fair I was still holding her breasts and fingers and thumbs had found her hardening nipples, my dick lurched again.

Pam got off my lap and stood before me again, her hands undoing the button at her skirt waist and then the zip. Her skirt fell to the floor, and she was standing stark naked in front of me, her bare shaved fanny calling to me. She leant forward and gripped my dick through my shorts and began to wank it slowly as her other hand slid into her crease, sliding between her labia, shining with arousal.

She pulled her finger away from herself and wiped it across my lips, I couldn't help but wipe them with my tongue, she tasted sweet. I wanted to taste more. She let go of my dick and then pulled the waist of my shorts down, my dick springing free.

"Fair enough, if you won't want to go upstairs, we'll do it here," she said, moving as if to crouch over me again.

"Okay Pam, let's go upstairs." I wasn't sure a cane sofa would be up to sexual gymnastics. My dick was complaining to me about the delay in proceedings.

Pam turned and walked naked out of the conservatory, the cheeks of her bum sliding past each other in a most enticing and erotic way. I could see the lips of her fanny peeking through the gap at the tops of her thighs. I stood and followed her to my bedroom, Sally's and mine bedroom.

Pam pulled the quilt back, thank goodness I had tidied the bed when I got up, and she lay on the bed, her thighs parted, her fanny glistening, shining in the morning sun that streamed through the window. I knelt on the bed and moved between her ankles and leant forward, my tongue running along her glistening.

Sweet yet heady, perhaps also a little salty, Pam's fanny was a slightly different taste to Sally, and not in an unpleasant way. My tongue pressed against her clitoris and Pam gasped, gulping in air, her breath held. I eased two fingers under my chin and pressed them against her entrance, she gasped again.

I held her clitoris between my teeth, gently, but enough to stop it sliding away, and at the same time my fingers were tracing a circle around her entrance. She was wet, very wet, and my fingers were drawn to enter, easily sliding down past her opening and into her depth. I eased back and added a third finger, such was her arousal that they easily entered, and then her fanny clamped and squeezed them.

I released her clitoris and began licking it as my fingers pumped in and out of her fanny, widening when inside, squeezed together at her entrance, her muscles strong. As I finger fucked her, I began to slide my nose along her valley, pressing against her clitoris, pushing at her urethra, a stray finger now laying across her perineum, crooking at her sphincter, Pam was gasping and muttering 'oh God, oh God.'

She clamped down hard on my fingers and her back arched, her fanny forced against my face and she screamed, her release powerful and she squirted, soaking my face and into my mouth, she was gasping as she bucked and then she slumped, falling back to the bed, her chest heaving. I eased my fingers out of her fanny and rolled to lay beside her.

She lay for a few moments, her breasts rising and falling as she gulped in air, and then she got to her knees and bent over my crotch. Her hand gripped my dick and slid my foreskin back, my glans feeling cool as the bedroom air hit it, and then warmth and heat as her mouth surrounded and engulfed my dick.

Pleasures were running through me, sprints around my body, my toes were curling and my fingers scrabbling at the mattress. She ran her tongue around my glans, along the lip of my rim, sensations that I should only experience with my wife were rioting in my body and I was gasping. My buttocks were clenched my shoulders pressing down and my dick thrusting up, trying to shag her mouth.

Her hand held my balls, rolling them in their sack, squeezing them gently to the point of light pain, and then her fingernail scratched along my perineum and the pressed at my sphincter. It popped and she was inside me, pressing, pushing a very strange yet utterly erotic sensation, one that I had little doubt she was doing from experience, knowing the results it could have. I gasped heavily as her finger was fully inside and I could feel it moving within me.

She began bobbing her head up and down on my dick, fucking me with her mouth, her tongue giving me a lick job as her mouth gave me a blow job, and her finger searching for my cum button had me right on the edge.

"Jesus, fuck, stop," I gasped, "otherwise I'll be filling your stomach not your fanny."

Pam eased away, her finger withdrew, and as her hand released my dick my foreskin rolled back over my glans. I lay back on the bed, gasping, that had been close, so close. Pam sat up and then crouched over me, facing my feet, her arse towards my face. I leant down and fisted my dick and pressed it upwards as she lowered herself.

My foreskin slowly freed my glans as her fanny sank onto my dick, her thighs pressing hard down on me, her fanny lips parting and splaying around my dick. She squeezed her fanny and my dick twitched in response. She rocked forward and her fanny rose upwards on my dick, I watched as her fanny lips seemed to caress and hold onto my shaft.

Down she moved, my dick once more disappearing inside her, her fanny lips fluttering around my shaft, her arse crinkle twitching and almost winking. I licked my finger and pressed. She gasped, her fanny squeezed my dick and she rocked forward, my finger now impaling her as well as my dick. She rocked back and forth, faster and harder, my dick being fucked in front of my eyes.

My pleasures were in free flow, I was gasping at the delights that I was feeling, my balls, squashed between my thighs, were pulsing and I could feel a little twinge of pain deep in the root of my dick. I was close. I could feel my dick moving through her fanny wall, a strange sensation on my finger, I wondered briefly how it felt for Pam.

I held her hips and began to drive into her, going harder and faster than she had managed, my bum lifting off the mattress and then pressing back into it. Her fanny petals were flapping around as I shagged, and her gasps were becoming groans of pleasure, "Jesus, oh shit," she gasped as we shagged.

I could not hold back any longer, my balls were screaming for release and I thrust up hard into her fanny and held, my dick erupted and spurt after spurt of my spunk shot into my mother in laws fanny. Pam screamed, she clamped, she gasped, she cursed and then she slumped down, and I relaxed and lay back on the bed. Pam raised herself, my dick fell out and spunk dripped from her fanny.

She lay next to me, "hush, don't say anything," she said as she pulled the quilt over us. Well, that was interesting, to say the least. I had just fucked my mother in law, given her multiple orgasms and filled her fanny with spunk, I hoped that she was protected, otherwise she would need to go to the chemist for the morning after pill, a mother in law pregnant by me would be difficult to explain, I knew that Bill had a vasectomy some years ago.

I lay on my back, my eyes closed, not quite dozing, not quite awake. I could hear Pam's steady breath as she lay next to me in her daughters marital bed. The bed moved, I opened my eyes, Pam was laying on her side looking at me.

"Well now," she said.

"Yes," I answered, not knowing what she was going to say, I remained neutral.

"I have to say that I do not know if that was the result of the Mounjaro or not, but that was unlike any sex I have ever had."

"Oh? Okay, er, that is pretty much how it is for Sally and me," I answered, and to be honest, it was. We shagged and she screamed, usually more than once. The MoJo just made me want to do it all the time, rather than around three times a week, which was our usual routine, although sometimes it was more often.

"Jesus Drew." She looked at me and then turned onto her back and stared at the ceiling.

"It has always been good with Bill, don't get me wrong, and if I am honest, his dick is a bit bigger than yours, sorry, I know men don't like hearing that."

I shrugged, I didn't care how big or small other people's dicks were, I just used mine to the best of my ability, it gave me pleasure and also my sexual partner.

"But," she continued, "I have never had multiple orgasms and have never felt so buzzing after."

"That is kind of a shame, I suppose," I said, "but if you were satisfied, before I mean, then that is all that was necessary, surely?"

"But that was before, what am I to do now?"

"I don't know Pam, buy a vibrator?"
