Growing
Summary: At six months pregnant Lily Potter takes a mission to check in on Severus Snape who has been seen with suspected dark wizards. When her now husband had stripped her old friend in front of their classmates many years ago she had made an observation about her friendâs anatomy that proves to be abundantly false.
(Author's note: This story is about Lily finding out that Severus is a âgrower not a showerâ as they say. I do not condone the idea that size means anything in relation to penises. All penises are good, valid and equal. I just thought it would be interesting to explore if she had assumptions and opinions and was forced to reckon with them.

Growing
Lily wasnât really sure what was going on with her decision making abilities while she was pregnant, but they were a bit screwy. She had been moved to make this bad decision by a series of smaller ones. Her brain knew that she had come here on a very specific mission and yet it was currently overcome. It was unable to provide helpful information other than Oh my god, itâs so big.
âYou thought I was small because of that day by the lake, didnât you?â Severus suddenly asked, voice full of smugness in the question. It was like he knew that her body was reckoning with being so full as he slowly inched the massive thing into her a little more with each small thrust. She should be reckoning with the fact she was betraying her husband. Instead there was only jaw dropping, brain emptying thickness splitting her open.
This whole month of her pregnancy her pussy had felt like a swollen throbbing beacon. Sex was her every thought, every dream. She was never not in the mood. Every caress of her sex was like scratching an itch that was never ending. Now she was dripping with eager excitement in this bad decision she was making. Bent over the back of his sofa, thinking about how full she was, how deeply that itch was being scratched, and not particularly about James.
âMerlin, woman. Listen to you. Does your husband never fuck you?â He asked with satisfaction after she had cried out when he reached his hand around her to pet her clit. With the little promise of pleasure her body had relented and let him press that last inch inside.
Lily did not know what to say to that. James did fuck her, but wasnât around very much lately. He was always off Order of the Phoenix-ing and telling her she could not join him because of her âconditionâ. It meant alot of being bored, alot of masturbating angrily when he didnât come home when he said he would. Then grief and terror when the hours passed and she imagined him dead, then anger again when he showed up with Sirius drunk as a skunk, from too much celebration over a victory.
Knowing what to say to Severusâs jabs at James was a moot point at this juncture as forming sentences was not going to happen. It was just. so. thick. She felt herself clinging to his length each time he withdrew, felt torn open again when he replaced it. She was sure she was a little torn, there was a stinging pain, intertwining with the pleasure. A problem for later. Her hormones had been running wild through her and they demanded this violence. Wanted her own destruction.
Severus was right of course. He usually was, annoying git. She had assumed he was small. That horrible day, the end of their friendship, she had seen- they had all seen⌠and it had been wrong of James to do it. It had been the cherry on top of the mudblood comment. Not only had Severus hurt her, but what she had seen while James stripped him had moved him into the category of pitiable creature to her. She had been so naive then, they all had. Of course, as an adult woman she knew that some men grew after they became aroused, not before. But Jameâs cock was always at his steadfast just above average length and width. Or so she had been told by James himself, for she had not seen over many penises.
Now, the truth that she had been so wrong was a fact she was being forced to consider with every bloody centimetre. This cock was more of a stretch than the stretch it would take to figure out how she got herself into this situation.
When it had come up that someone close to him should go see if they could find out if he was a death eater now, she had volunteered without even casting a consulting glance at her husband. So many months of doing nothing, checking in on a former friend who has been seen in public with suspected dark wizards was hardly a mission she was too frail to perform. James was as angry as if she had volunteered to take out He-who-must-not-be-named himself with a toothpick and teaspoon as her only weapons. He had yelled. It had been ugly.
Lily had failed to see how it was going to be a problem. She knew that Severusâ father had recently passed and that he had inherited the house and moved back into her parents' neighborhood. That was all the pretense she needed. To go by and see how he was doing. She hadnât expected him to be so transformed.
When he answered the door, it had not been the string bean with oily hair and old clothes who answered the door. He had very suddenly become a man, it seemed to Lily as he opened the door to his house. He was transformed, new clothing, well kept. She supposed being best friends with a Malfoy had a dress code.
There had been a few tense back and forths between them, but while he intimated he had no interest in seeing her, he did not close the door. Intent on her spying mission she had kept up pressure at forcing a reconciliation, all the while keeping track of his newfound confidence, his cocky kind of air when he showed her the changes he had begun making to the run down house she had seen only a couple of times while they were kids.
She tried to pry into his life, asking about his job and everything she could think of without asking outright. Severus was too clever for this kind of direct approach she realized too late. She felt like the one under observation, his eyes were burning her with their direct stare, like he could see inside her. She hoped he was just surprised to see her. When he tried to get her to leave she let herself give him her full bright smile. Let her eyes twinkle. It was as close as she would dare go to flirting with him. She immediately felt guilt about it, for trying to exploit feelings she knew full well he had before.
She had almost left. She had almost walked right out the door when he started flirting back. The worst thing about it was that when she responded, it didnât come from the calculated spyâs intentions, but instead it came from something much lower in her body; that pesky ache that would never cease its wanting. Why had she needed attention today? Needed it extra badly that James was giving her the silent treatment.
One small bad decision to flirt after another and as they were saying goodbye he very suddenly pulled her into an unexpected hug. His hand cupped the back of her head, his fingers parting the strands of her hair too intimately. The hold was too close and when he had pulled her away from him and locked eyes with her. She knew full well what the eyes were asking, and she knew that if she did not pull away that he would take her stillness as a yes to his silent question and kiss her.
Her head had been screaming to break away but something deep inside her had a little too much curiosity about a different version of her life. When the distance between their faces slipped away to nothing, his lips ignited a fire inside her hormonal body. Like how sometimes she would just be ravenous to eat everything in their cottage, now she was ravenous for Severus and there was nothing to be done about it. Nothing would stop this very primal urge from having its say.
His hands started grabbing at her like he couldnât quite believe his luck. No one expects an old friend and flame to show up at their door. Certainly no one expects them to crumple at the slightest attempt at seduction, but here she was acting like the easiest slut that ever lived. As the pretence of leaving was dropped, so was her bag and suddenly this snogging was taking place against the back of the sofa that was on the way to the front door. He had peeled off her denim jacket and she had heard the metal buttons hit the floor nearby.
Severus put her behind up on the back of the sofa so he could part her legs. Lilyâs thighs were happy to receive the visiting hands, her sundress provided very easy access to her legs. At her eager mewing he went right to her centre and found that under that growing baby bump she was soaked through her cotton thong already, he moved the damp pittance of fabric out of the way and wasted no time in inserting his middle finger deep inside her.
âI finally have my fingers inside Lily Evans.â He teased into her ear. âRemember that summer when we were fifteen and you were so⌠horny and angry at everything? You almost let me that day by the pond. Remember?â
âOf course I remember.â She fairly panted as he explored her slick entrance.
âYouâre even wetter now than you were as a ready teen.â
âHormones.â
âHere I thought you were here to poke around and ask questions for that club your husband is part of and now I see why youâre really here. You want to be fucked, and your prig of a husband isnât doing it for you.â
âThatâs not true.â Lily had tried to assert but her voice quavered as her old friend's long fingers had begun rhythmically plunging in and out of her. Then she moaned in a way she had not done during sex in quite some time. The moral wrongness about what she was doing, mixed with her bodyâs needs made her feel quite unhinged. She forgot about Severusâ unkind assertions and reached to grab his cock through his trousers.
She palmed him and apparently that was all the permission he needed, he took it out and her jaw fell open. He stroked the massive thing and looked at her while she looked at it. âMerlin, Sev⌠thatâsâŚhuge.â
âBe brave little Gryffindor. You can take it.â Was his teasing reply as he had turned her over so she was bent across the sofa back. Then he had started rubbing the head of this tree trunk up and down her soaking wet slit. When he grabbed her thong and pulled it out of the way she shivered with arousal as he stared at her most intimate places.
âI used to lay in bed upstairs in this house as a sixteen year old imagining this⌠Trying to guess what the head of my cock would look like surrounded by your pretty copper coloured curls. My imaginings were very accurate I think. Such pretty lipsâŚthey look quite nice around me. I take it from your moaning that you want me to put this inside you?â
Saying yes felt too guilty. Lily murmured in a tone of agreement instead as if that was less of a betrayal of her husband. Her mouth hung slack as he made his first press, the head of it alone made her feel full. Some minutes later, when he was fully inside of her and finished with his interrogation confirming she had assumed he was small he kind of started laughing.
âYour asshole of a husband showed most of our year my cock that day⌠serves him right that itâs in his wife now.â Severus smugly asserted while he fucked her. Lily knew she should tell him to stop saying such things but she found his words made her even more aroused.
His hand came around to her clit again.âLetâs make you come on it, shall we?â He asked rhetorically before increasing his pace. Her moans fell out of her mouth with no stopping them. She had never felt so full before, she had never needed to come so bad in her life. âI have to say, knowing Iâm cuckolding your husband makes it really hard not to come right⌠this⌠second.â He grunted.
His fingers on her clit in combination with his continuous stretching of her pussy was bringing her to the brink. âLook at me in the mirror over the fireplace. I want to see your eyes as you come on my cock, Mrs Potter.â
She hadnât noticed the mirror before then. Knowing he had been watching her face this whole time, every slack jawed moment of taking his cock had been carefully observed Lily Potter began having an orgasm. It was big and it didnât stop. She just kept finding new levels of pleasure as his cock ravished her senseless.
In the mirror she saw a completely wanton woman playing dangerously with her life as she knew it, and the sight should have woken her from her reverie but it did not. Her former friend finding his release inside her should have made her snap out of it, but it did not. She relished the depth of the heat he had just released inside her and as soon as he withdrew she felt it start dripping out of her. He held her still with two hands, pressing her against the sofa, looking at the mess he had made before he let her go.
When she was back on her feet and the lust had begun to fade, she pulled her panties back into place but knew the wadded up wet middle of them would do next to nothing to stop his orgasm from spilling down her leg. She would need to spell it away but first she needed to find her bag and get out of here. She grabbed it and she ran with a hasty goodbye. The guilt flooded in as soon as the tide of lust had gone out.
Halfway down the walk his hand was on her wrist, she yanked it back. He looked at her with squinting eyes. She wondered if ripping her wrist away was too much like another rejection of him. âYou forgot your jacket.â He informed, handing the bundle to her, but not releasing his side of the garment.
âThank you.â She said quickly. Out in the open now, James could be watching, waiting for her. He knew where she was.
âIf you ever need⌠anything.â Severus began and trailed off. He seemed to remember something, a wall he had let down. He stopped speaking. She knew what he meant. She knew where to find him. He released the jacket and turned on his heel and back into his house.
Lily muttered the spell that would clean up the bulk of the slipperiness between her thighs before crossing his garden gate. The spell line for defences on his house must be there for as soon as she crossed it, she heard James whisper to her from under his invisibility cloak.
âYou had me worried sick you should have been home half an hour ago.â
Lily remained silent as they walked down the block, but James kept up his whispered questioning. Finally when they were actually a safe distance away to speak she said âPeople do not just come out and tell you when they are a death eater you know. I was talking to him like an old friend as the mission called for. He showed me the improvements he was making to his house. I do not need a babysitter for this.â
âWell. Is he a Death Eater?â
âI didnât see any evidence of dark magic in his house.â
âThat doesn't mean-â
âI KNOW.â She snapped. Suddenly the baby was moving and she had to stop walking and touch the growing bump. One growing thing at a time. Her growing annoyance at her husband would have to wait. It always seemed like the little one got upset when she did. It fussed inside her, kicking her in the bladder.
James must have noticed her stop and hold her belly for suddenly he stopped yelling, got softer, turned back into the man she loved for a moment.âAre you alright? Is it kicking? Iâm sorry about how Iâve been handling this. I just feel so protective of you. If he so much as laid a finger on you Iâd kill him.â
A clearing of a throat behind them and Lilyâs head snapped up, her eyes widened as she took in Severus having just caught up with them. His eyes peered at the space where James was standing like he could see through the cloak. Of course he couldnât but James had been speaking too loudly not to be heard if he had been close.
Severus extended his hand out, inside was Lilyâs locket. It must have come unclasped somewhere in his house. Her cheeks burned red at looking him in the face beside her hidden husband. âLook what I found⌠in the pillowsâŚâ his eyes watched the space beside Lily as he said it. How like Severus to choose to say pillows instead of cushions. To paint her husband a picture, to provoke him from coming out of hiding.
âThanks.â She said ungraciously, snapping the precious object out of his open palm.
âI just want to sayâŚâ Severus began, purposefully trying to make her sweat, to panic, to reveal her hidden husband. Lilyâs mind came up with a hundred endings to that sentence that she wouldnât want James to hear. Was he about to blow up her life on purpose? His eyes flicked to the empty space Lily was desperately trying not to look over at. âThat it was kind of you to visit, and open up to me. Iâm glad I got to fill you in on what Iâve been up to. I hope youâll come again.â
Lily could have choked on all the double meanings. She managed to squeak out a âSee you around.â With a passing attempt for a casual smile. It was all lost on James luckily.
Later, when James was bent on reconciliation and apologies, she found herself having makeup sex, trying not to show her guilt, her hesitance to do it when she had been begging him for it just that morning. No shower, no bath could wash away the growing feeling that her husband was a small, petty person, and worse⌠that his cock would never make her feel like she had on the back of Severusâs couch as her eyes rolled back in her head and he had thoroughly and deeply scratched that itch.
