After a poorly executed treasure hunt, Sebastian Sallow must make it up to you somehow. note: something about shower sex with Sebastian just really appeals to me idk. This is mostly self-indulgent but I liked it enough to post it. It's way longer than I thought it would be lmao. 99% unedited because I'm lazy. i've never like properly tried to write smut in a way that makes sense for other people bc of course I can picture what I'm writing in my head, so it's a little detail lacking currently. it'll be interesting to see my writing style progress.

You stood beside Sebastian Sallow at the edge of a dark lake found deep within a cave he’d read about. Sebastian had heard a rumor of a ‘great’ treasure within the cave, and had begged you to come along with him to retrieve it once he had located it. You had agreed, but now you were a little less enthusiastic. From your spot on the shoreline, you could see a painted chest sitting on a small mass of land closer to the middle of the lake. The only way to the chest was to swim. You’d both spent a rather long time trying to summon the chest, and it wouldn’t budge.

“Draw sticks?” Sebastian asked, tilting his head as you looked up at him.

“You always cheat.” You frowned. You already knew it was going to be you to swim across the gap. Sebastian’s ability to ask something of you and for you to agree was… unfortunate at times.

“You’re just so much better than I am at everything.” Sebastian pouted. His hand stroked down the back of your arm, the warmth piercing through the thin fabric of your shirtsleeve. You stepped out of his touch and kicked off your shoes with a sigh.

“This treasure better be worth it, Sallow.” You looked back at him, unbuttoning your trousers and stepping out of them. You pulled your shirt off, discarding it next to your trousers. There was no use in getting all of your clothes wet. Aside from your undergarments, you kept the small pouch that Ominis had helped you enchant to hold far more than should be possible for the size of the pouch. You walked to the edge of the lake, looking down into the murky water. A pulse of fear passed over you, making your heart flutter. It was unnerving not being able to see anything in the lake - you didn’t like not knowing what was coming. Taking a deep breath, you stepped off the edge. You panicked momentarily as you plunged entirely under the frigid water. There was no gradual slope to deep water, it was just a drop-off. You pushed upwards, gasping for air as you surfaced.

“Are you alright?” Sebastian asked, his concern would be touching if he hadn’t just guilt tripped you into doing this.

“‘S cold.” You managed to say, the cold water made it a little difficult to breathe. You kicked your feet and used your arms to propel you forward towards the island, spurred on by the thought that you had no idea what was beneath you. The sooner you were out of the murky water the better. It didn’t take you long to get to the island and haul yourself up onto the stone surface. Being in the air was even worse than the water now, the cool air of the cave chilling you thoroughly to the bone. You hurried across towards the chest, silently hoping it would be easy enough for you to open.

“What’s in it?” Sebastian called out, his voice echoing around the chamber.

“Alohamora!” You cast. The lock clicked open and you eagerly lifted the lid. The chest held an assortment of jewelry, and a bag of gold coins. They weren’t galleons, they were some sort of ancient muggle currency. They’d certainly fetch a fair price either way. Your anger towards Sebastian was fading quickly, especially as you picked up a particularly ornate necklace. You made quick work of stuffing everything into the leather pouch, eager to be out of the chilly cave. It was easier this time jumping back into the water, you knew what to expect this time. You swam back towards Sebastian who called out words of encouragement. As you neared the middle of the stretch, something felt wrong. An overwhelming sense of danger filled you, and that’s when a cold hand wrapped around your ankle. You barely had time to gasp for breath as that hand was joined by several more and you were pulled under the surface.

Sebastian yelled out your name as you disappeared under the surface. He ran to the edge, but could only see a stream of bubbles coming up from the black water. Panic clouded his mind at the thought of you being hurt, and it would all be his fault. This wasn’t exactly an enemy he could see and fight. He had no idea what to do, how could he save you if he couldn’t see you? He reasoned that you were very capable and strong, you’d gotten out of sticky situations like this before. Far too much time had passed for his comfort, and he knew he had to do something. He dumped his cloak on the ground, preparing to dive in for you when he saw a flash of red light from the deep. As soon as he could see you, he dropped down and snatched your hand hauling you out of the water. Your skin was freezing cold, and you began to cough violently as you flopped down. About a dozen grindylows floated to the surface dead until their surviving companions yanked their bodies downwards, no doubt to feast on them.

“Are you alright?” Sebastian gasped out, putting his hand on your shoulder. You snatched his wrist, looking up at him with bloodshot, furious eyes. They almost seemed to glow with your rage. Sebastian knew then he was in a lot of trouble.

“Don’t.” Your voice was a strangled wheeze, and Sebastian withdrew his hand like he’d been burned. He had half a mind to run away from you, his eyes flicked to your wand still clutched in your other hand. He knew what you could do with it and he suddenly wasn’t keen on dueling with you. Sebastian obeyed, stepping back from you as you got to your feet. He apparated as soon as you pointed your wand at him. The last time he’d pissed you off he had ended up with no eyebrows and two inch long front teeth that had taken three hours for Nurse Blainey to fix.

Sebastian ran the rest of the way back to Hogwarts, he knew he didn’t have much time to hide from you or get you calmed down. He had to find Ominis. If anyone could get you to calm down, it was Ominis. Sebastian knew he had a habit of fanning the flames of your anger, while Ominis did a wonderful job of quelling them.

Students watched him and more than one person called out to him as he ran past. He was panting heavily by the time he found Ominis who sat with Poppy Sweeting. Poppy looked up at him with wide eyes as he thundered to a halt in front of them.

“What did you do?” Ominis asked calmly.

“You have to hide me!” Sebastian was desperate.

“What did you do?”

“Nothing! I didn’t do anything - how was I supposed to know there were Grindylows?”

“Grindylows? Where did you find Grindylows?”

“A cave. It’s a long story. Please hide me. She’s going to kill me.” Sebastian pleaded.

“Is she alright?” Ominis asked. Sebastian knew his time was running out. He had to find somewhere safe until you cooled down enough for him to safely approach. He’d make it up to you somehow. He’d find a way to make you forgive him.

“She’s fine. Please, Ominis! You have to talk to her. I’ve never run so fast in my life.”

“You ran from her? What is wrong with you?” Poppy burst out, smacking Sebastian on the arm. He gave her a stunned look, unused to such outbursts from her. Ominis sighed sharply through his nose, shaking his head slowly.

“My friend, I’m afraid there is nothing I can do for you. She only gets angrier when they run.” Ominis’ lips pressed together in a firm line. Sebastian knew the bastard was trying not to smile. When they run. Sebastian knew he was right, he’d been on enough quests to rescue beasts with you that he knew how furious you got when you had to chase what you sought.

“I’ll buy all your butterbeers for the rest of the year!” Sebastian burst out. Ominis tilted his head, considering the offer. Sebastian bounced on his feet, anxious to get to safety.

“Go. I’ll try to talk to her.” Ominis said, smirking.

“SALLOW!” Your voice boomed through the hallways, and Sebastian turned and ran.

“My goodness! What happened to you?” Poppy Sweeting asked.

“Where is he?” You snapped, and Sebastian took a pinch of floo powder and went as far away as he could.

You knew Sebastian had put Ominis and Poppy up to pacifying you, and while your friends hadn’t eliminated all of your anger they had made you promise not to kill Sebastian. He should consider himself lucky that you respected Ominis and Poppy far too much to go against their wishes. You were cold, damp, and uncomfortable, so you had decided to give up your hunt and make your way to the showers. You stood in the warm water, letting it rinse off the remnants of nasty lake water from your hair and body. You were absorbed in fantasies of revenge as you ran your hands through your hair to loosen some of the knots that had formed during your pursuit of Sebastian. The warm water was a blessing compared to the frigid and dingy lake.

You let out a little hiss when a cold breeze pushed around the steam you had accumulated in the shower room leaving goosebumps all over your body. You shrank further into the shower, annoyed thoroughly with whoever was intruding on your murder plotting time. When the steam closed around you again, you sighed with contentment and closed your eyes. Broad hands gripped your hips. You knew those hands. Sebastian planted kisses on your shoulder as his chest pressed against your back. You ignored him, just as you ignored how easily his touch affected you.

“I’m sorry,” he murmured, nudging your cheek with his nose before kissing your jaw. “Let me make it up to you.” He said, pulling you back closer to him. You could feel his hardness pressed against your backside, and it took a lot of effort to not react. You fought to keep a straight face as his hands moved from your hips. One hand moved up towards your chest, the other down to your lower belly. Sebastian kept you pressed against him as his knuckles lightly traced the underside of your breast. He leaned in and kissed your neck as his fingers brushed against your nipple. You were determined. Adamant. He wasn’t going to get a single thing from you. You could feel him watching you very carefully, and when he bit down on that spot where your neck met your shoulder you couldn’t stop your reaction. All it took was a slight tilt of your head, and he knew he had you.

“There’s my girl.” He murmured, his hand on your lower belly traveling downwards. His girl. Eternally possessive. When his fingers slid between your wet folds, he let out a dark laugh.

“I knew you wanted it. Look how wet you are already.” He said, nipping your ear with his teeth. He began to rub his fingers in small circles over your clit and you relaxed into his arms.

“I hate you so much.” You breathed out, one hand reaching back and gripping Sebastian’s thick hair.

“Mmmm I can tell.” The depth of his voice in your ear sent chills through your entire body as he kept up a steady, lazy pace between your legs. His other hand rolled your nipple between his fingers. You subtly ground your backside against Sebastian’s erection. You smirked at his abrupt groan. His fingers on your nipple pressed harder giving you a sharp pinch. You twisted enough to look up at him, marveling in his appearance. The flush of his cheeks, the fire in his eyes, the arrogant bastard smile playing at his lips. He let go of your nipple, his hand coming up to wrap around your throat. He turned you around and pushed you against the wall of the shower cubicle, not once stopping those lazy little circles that were quickly unraveling you. Your hands fell to your sides.

Sebastian kissed you then, deep and intense like he always did. His tongue brushed against your lower lip, and you opened up for him. His taste was intoxicating and mixed with the feeling of his teasing touch on your sensitive clit you were approaching an euphoric sensation. You moaned into his mouth as he slid two fingers inside of you.

“Fuck, I love it when you moan like that.” Sebastian’s voice was husky as he mumbled against your lips. He kissed along your jaw and down on your neck finding that spot that made you so weak. His hand moved from your throat up to your hair which he gripped tightly as his fingers curled delightfully inside of you making sighs and small moans tumble from your lips. How he could do so little to make you feel so good was incredible.

“It’s so hard to be patient for you and that sweet cunt,” his breath tickled your neck, “can you be a quiet girl for me?” He asked, fucking you with his fingers. Right. You were in the shared showers during a Saturday afternoon where all of your classmates had all the free time in the world. You nodded, and instantly regretted it from the grin on his face as his fingers slid out of you and he knelt on the ground in front of you. One hand prompted your left leg to lift, you obeyed and he put it over his shoulder. Sebastian’s hands floated up and down your thighs as he moved in closer. He bit down on the sensitive flesh of your inner thigh, and your hand flew to your mouth to stifle your cry. He looked up at you with those eyes of fire, his tongue experimentally swiping along your entrance.

“Sweet. My sweet girl.” He gave a low groan, and started his assault. His tongue swiped shapes over your clit, and you had to bite down on your hand to stop yourself from making too much noise. He flattened his tongue lapping you up, you were already sensitive from his earlier work and it wasn’t taking long for an orgasm to start building up. He seemed to know it too. His tongue swirled over your clit, and he slotted two of his fingers back inside of you.

“F-fuck, Sebastian.” You stammered against your hand at the overwhelming sensation. The pressure of his tongue against your clit and his fingers curling against your sweet spot… it was too much. Your head fell back as you began to fall apart, your fingers lacing in Sebastian’s hair for fear that he would stop. You bit down harder on your hand to choke on the scream as your legs began to tremble. Sebastian moaned against you as you came for him. He let you ride out your orgasm on his face, not stopping until your fingers loosened slightly from his hair. You looked down to see him rock hard, flushed, and his eyes seemingly begging for you.

You took him under his chin, your leg falling to the side as you prompted to stand. He stood, his fingers once again leaving you empty. His hands curled around your ass, and he lifted you and pinned you between him and the cubicle wall. Your legs squeezed him, holding yourself up as he positioned himself at your entrance. His lips crashed against yours when he thrust inwards, both of you making a desperate attempt to remain quiet. His hips rolled as he fucked you hard and steady. When he was feeling particularly cruel, he would edge you until you were in tears, however today he was in just as much need as you were. You loved the way he filled you up. His steady pace had his head lightly pressing your cervix, hitting all the right spots. You hadn’t realized how good someone could make you feel until you’d slept with him for the first time. With the way he was fucking you, you could feel your pleasure rapidly approaching for the second time in a matter of minutes.

Sebastian was in your ear, whispering about how much he loved you, how he’d always protect you, and how he was oh so sorry for letting you jump into that lake for the Grindylows to attack. You were in ecstasy, unable to respond as he ground his pelvis against your sensitive bud. His rhythm faltered slightly, and you knew he was close.

“I love you.” You breathed out, knowing it was exactly what he needed to hear. His response was a low, guttural groan. His thrusts got sloppier, before he abruptly pulled out. You dropped your hand quickly, wrapping around his shaft and finishing him off as he came all over your stomach. Your legs dropped to the ground, and Sebastian’s head dropped to your shoulder as you both fought to catch your breath. After a few heartbeats, his head lifted and he kissed you again. His kisses after sex were always so sweet, so emotional.

“Are you okay?” He asked you, tilting your chin up to meet his gaze as he stood up straight. You nodded, admiring the loving glow in his eyes.

“I really am sorry.” He promised.

“I know, Sebastian. It’s alright.” You caressed his cheek, and he pulled you in for a long embrace. You stood like that for a long time, before cleaning off properly and getting out of the shower before someone could catch you in there together. You felt relaxed now, your anger completely forgotten as Sebastian put a fluffy bathrobe around your shoulders and pressed a kiss to your cheek. He may be sweet now, but you knew it was only a matter of time before he filled you with so much rage you thought you could kill him. At least you could look forward to how he would make up for it.

“So, are we still splitting the treasure 50-50?” Sebastian asked, grinning at you. You smiled back at him shaking your head at his audacity, perhaps he would be making it up to you sooner than you thought.
