Skinny Dip- Sirius Black x Reader (Mauraders Era)

"C'mon c'mon y/n it won't be that cold I promise, I'll cast a charm to keep us warm," Sirius smiles dragging you to the black lake. It was way past curfew and you had to use the map to make sure you could get past Filch without getting caught. You shiver at the crisp air, summer was on its way but the spring nights were still too harsh for you to handle. As soon as you two make it to the black lake Sirius wastes no time stripping nude, tossing his clothes on a blanket he has laid out for you two for later and casting a charm on you both. You however strip yourself slowly, a bit paranoid about getting caught and constantly looking around you thinking every sound was a professor waiting to catch you.

"Oh y/n don't worry no one is here," Sirius chuckles waiting for you to finish undressing. As soon as your panties hit the ground Sirius picks you up tossing you over his shoulder and running into the black lake. You shriek as the ice-cold water splashes around you two. The charm is not cutting it for you but before you can think Sirius tosses you off his shoulder and into the water. Goosebumps flood your body as you flail for a minute before pressing your feet firmly on the rocky sand and standing up from the water.

"Sirius!" You shout splashing water in his direction but he has already broken out into a fit of laughter.

"Lighten up!" He chuckles and moves closer to you keeping his hands on your waist and pressing a kiss on your forehead. The warmth of his lips sends a shiver through your body. You look up at him and he has his gaze set to the sky. You look up and see the night sky lit up with stars. The moonlight reflected off the water. You both stay like that for a little while in a comfortable silence with your wet naked bodies pressed against each other generating a comforting warmth, staring at the beautiful night sky. You lower your gaze and much to your surprise you find Sirius staring at you and not the stars illuminating the sky above. Your body flushes red and can't help but smile sheepishly. You struggle to find the right words but before you can even open your mouth to speak Sirius starts, "Y/n you're so beautiful," he smiles down at you and you can't help but look down in a lame attempt to hide your blush.

"Siriussss," you whine embarrassed.

"I love the way your eyes sparkle under the moonlight darling," Sirius continues with a big smile on his face and his eyes full of love. His hands grip your waist a bit tighter and you absent-mindedly press your body against his trying to close up whatever little bit of space is left between you two. His touch is electrifying. You look up at him and your eyes are filled with lust. Your need for him grows more and more with every second that passes by. A mischievous smile grows on his face as he leans down capturing your lips in the most passion-filled kiss you ever had. You instantly melt into the kiss, your body feeling as if it was on fire. You let a soft whimper leave your lips and find its way into the kiss. Sirius lets one hand slip from your waist and it slowly makes its way down your lower back and cups the bottom of your ass. Your breath hitches as his fingers are so close to your throbbing cunt. You break the kiss and send your lips to kiss down his jawline and his neck. You can't help but to bite down and suck on the spot under his earlobe and by his jaw that you know makes him go feral. Sirius's body reacts just the way you had expected, his whole body shuddering as he lets out a low groan. You smirk to yourself loving how riled you get him. You take a second sending your hands and entangling them in his hair as you take in the intoxicating aroma of his natural scent mixed with the fading scent of whatever posh cologne he has on this time. Sirius takes advantage of the way you are practically clinging to him to swoop his arm under your thighs and bring you to straddle him. You let out a quiet yelp from the quick movement feeling as your pussy rubbed against his cock and lower abdomen. You begin to yearn for his cock needing to feel filled up by his thick length. You tighten your legs around his torso and move your hips so your folds are against his cock and slowly grind your hips moving your folds to stroke his cock. You let out a soft moan and keep moving your hips and listen to the ungodly sounds that fall from Sirius's lips. You feel his body shake against yours, his knees buckling from the pleasure you're causing him just from the slow movement of your folds against him.

"More Sirius," you breathe into his ear. Without saying a word he carries you out of the lake and lays you on the blanket he had spread out. You stare up at the stars above as Sirius climbs on top, his tip teasing your entrance. "Please Sirius, don't tease me I need you," you whine and he leans down to bring you into a heated kiss. His lips feel like home and every muscle in your body relaxes, this allows for his tip to slide into you. You gasped a bit at first from the stretching sensation from his tip. While deepening the kiss Sirius sinks his full length into your throbbing cunt, your walls flutter around his length. "Oh fuck Sirius!" You cry out. Your moans were music to his ears, sending a shiver down his spine.

"Oh fuck Y/n, I love when you say my name like that," he growls gripping your hips to keep you in place as he pounds into you. Your walls clench around him greedily and your legs feel like jello. You rest your hands on his shoulders and can't help but dig your fingernails into his shoulders while you scream his name. He moves his lips to plant big wet sloppy kisses on your neck while maintaining his consistent hard but quick thrusts. Sirius finds the sweet spot under your jaw and begins sucking on your soft sensitive skin hungrily. He nibbles and flicks his tongue over your sweet spot as he sucks leaving a pulsing bright purple hickey on your delicate skin.

"Oh Sirius," you moan breathlessly as your breaths begin to shorten and your breathing becomes quicker as you feel your climax approaching, the tension and nerves building up in your stomach. Your walls can't help but keep clenching around this twitching cock.

"Hold it for me, love" Sirius moans knowing that you're close from the grip your pussy has on his cock. Your mouth falls open and all you can do is become a moaning mess underneath him, focusing on not cumming with every thrust that hits your G-spot. "God y/n you're so fucking tight," Sirius groans, his thrusts becoming sloppier and this cock twitching inside your cunt. You could tell how close he was but he was trying so hard to hold it because neither of you wanted this moment to end, however holding it was getting harder and harder for you to do. All you needed was his okay and you'd come undone right under him.

"Oh Sirius please I have to cum, I can't hold it anymore," you whimper, squeezing your eyes shut and your nails digging into his skin. Your begging seems to send him over the edge as his grip on your hips tightens leaving an instant bruise.

"Fuck, y/n! Cum darling," Sirius grunts as he takes all his strength to pound into you until he topples over releasing into you, his head buries into your neck as he continues thrusting into you slow and sloppily for you both to ride out your orgasms. Feeling his cum fill you up sends you over the edge, a wave of pleasure washes over you as you cum on his cock. Your legs tremble around him and your whole body shudders underneath him. You tangle a hand in his hair and hold his head where he rests in the crook of your neck. You both lay there panting. The scent of sex mixes with the scent of the outdoors and fills the air around you. You both relax in each other's arms. You love it when Sirius lays on you, his weight on your chest relieves any anxieties you had throughout the day. You tilt your head down to kiss his head. "I love you, Sirius," you say breaking the silence.

"I love you more Y/n," he says lifting his head to smile at you. You spend the rest of the night cuddling under your star.
