"Sirius?" you asked gently, your hand placed flat on his chest as you snuggled under the covers.

"Yes, Sweetheart?" he smiled, looking down at you, tucking his long hair behind one ear. "You alright?"

You bit your lip for a moment, before meeting his eyes. "I'd like to try something new. You know... in the bedroom..."

Sirius grinned slightly, sitting up slightly. "Something new, eh? What like, love? We talked about food play and temperature play, but we got a bit distracted last time-"

"No... I don't mean like that... I was thinking... I'd like to- to try being the dominant one,"

Sirius raised his eyebrows, trying to hide his grin. "The dominant one, eh? You really are a little dark horse, aren't you pet?"

You pouted. "Don't tease me!" you said.

Laughing, Sirius said, "Or what? You gonna spank me?" you fixed him with a stern look and he held his hands up in surrender. "Alright, alright. If you wanna try it, love, I don't mind. God, it's been a while since I bottomed..."

A few days later, you were backed up against your bedroom door, kissing Sirius hard, your fingers hooked in his belt loops to keep him close to you. You could feel the hardening bulge straining at his trousers, pressing against you belly and groaned. "Get on the bed, Sirius," you whispered, releasing your grip. Sirius looked down with a bemused expression, eyebrows arched and a cocky smirk tugging at his lips. Your nostrils flared and you put a hand on your hip. "On the fucking bed. Now," you said, a little firmer, gaining more and more confidence, especially as the man before you practically sprinted to the bed.

You admired him laying there for a moment before reaching to stroke his hair out of his face. "Colour?" you whispered, biting your lip.

"Green, my love. Go to town on me... go in my bottom draw," you coked your head to the side and nodded, squatting down to the bottom drawer as he asked. "Right at the back..." you reached out and gasped, your hand wrapping around a thick fake cock, with a series of straps attached to it. "Did a bit of transfiguration," he said proudly. "And there's some lube there too. Magical. It'll save you a job of prepping me,"

You smiled appreciatively, beginning to strip, gesturing for him to do the same. as he was kicking off his trousers, you figured out the harness for the strap-on, before turning around and facing him. He was still in his boxers. "Those need to come off," you said and Sirius nodded, wriggling out of them. You then handed him the bottle of lube. "I want to see you touch your pretty arse for me, Sirius," you said lowly, smirking slightly as he flushed. He nodded, drizzling the lube on his fingers before pressing them to his hole, pushing gently. He let out a high pitched moan, slowly pumping his fingers. He locked eyes with you, biting his wobbling lower lip to suppress his needy moans which were growing louder by the minute. You smiled softly. "Good boy," you cooed, and he nodded.

"Please..." he whimpered, looking at you pleadingly. You licked your lips and raised your eyebrows.

"Please, what?"

"I- I want you to fuck me! Please, YN!" he groaned out, thighs shaking. You smiled gently and gently tugged on his wrist so he removed his fingers from his now prepped hole. You coated the dildo in plenty of lube before lining up with him, slowly pushing in. Sirius shuddered, fisting the sheets until his knuckles were white, a low moan escaping his lips.

“There’s a good boy...” you moaned lowly, bottoming out inside of him. “Taking this cock so well, baby,” he locked eyes with you, nodding desperately, hips wriggling as he tried to grind himself on the strap on. “Aww... do you want more, baby? You’re trying to fuck yourself on my cock like a little slut,” Sirius moaned at your words, nodding desperately. You smirked, beginning to rock your hips, angling them experimentally until you brushed against Sirius’s prostate, making him gasp and arch his back, letting out a whiny moan. You groaned, holding his thighs apart and fucking him relentlessly, hitting his sweet spot over and over until he was whimpering and begging for release. “Gonna come, Sirius? Gonna come from your tight little arse getting fucked?”

Sirius cried out and nodded, grabbing at your hand. You smiled, thinking he just wanted to hold onto you as he came, but he surprised you, pulling your hand up to his throat. You raised your brows and smirked, squeezing gently. Sirius’s eyes rolled back as he pleaded, and you increased the speed of your thrusts. “Good boy. Come for me, Sirius,”

You didn’t need to tell him twice. With a harsh cry, he came, writhing on the mattress as his cock spurted ropes of cum over his belly. You released his throat and slowly pulled out, cleaning and vanishing the strap on with magic, before cleaning Sirius up. You went to his side, pulling him to your chest and kissing his head gently. “You did so well for me, baby,” you cooed, stroking the tangles out of his hair. “Do you want a hot bath? You’re gonna be sore after that,..”

Sirius shook his head, burying his face into your breasts. “No... wanna be sore. Fuck, it’s been ages... that was good,” you grinned at his garbled words, rubbing his back.

“If you insist, love. But you’re gonna drink some water for me, alright?” He nodded, and a few summoning spells later, he was sipping at a bottle of water. “There we go. Come here, lovely,” you said and smiled as Sirius nuzzled into you. “Sleep, sweetheart... did so well for me,”
