A Soulmate's Kiss

Chapter 8

Harry groaned in his sleep, rocking against Sirius' thigh as the heat started simmering again. Sirius sensed Harry's movements, hand going to grip Harry's hip roughly as he began grinding against him. Harry whined, shifting and squirming, still mostly asleep. Sirius hummed in his still sleepy state, leaning forward and nibbled at Harry's neck.

Harry moaned. His head tilting back

"Need me, sweetheart?" Sirius hummed with a soft chuckle.

Harry just whimpered, patting where he could to try and drag Sirius closer.

"Okay sweetheart, don't worry, I'll take care of you." He promised, rolling Harry over to where he was on his back and settling between his legs.

Harry opened foggy eyes, watching Sirius dazedly. Sirius situated himself and lined up with Harry's entrance quickly before entering him hard.

Harry jerked, crying out as he scrambled for a hold, grinding back. "Daddy! Yes!"

Sirius gripped Harry's hips and thrusted hard into him, over and over.

Harry scrambled for a hold, loud cries leaving him with each thrust.

Sirius felt his knot start swelling, "Going to knot you sweetheart, fill you up so good" He warned.

"Yes! Please Daddy, fill me up, fill me up completely, make me drip..." he gasped, crying out as he came suddenly and hard.

Sirius groaned, pausing for a moment to bend down and smash their mouths together with a moan. 

After a moment he pulled back, nipping at Harry's lips "going to fill you up until you can't take any more, until it's seeping out of you and your stomach stretched from all of my come." He murmured against Harry's lips before going back to thrusting hard into him until his knot caught.

"Going to look so gorgeous" Sirius panted, letting out soft growls.

Harry flushed. His eyes somehow grew even darker as he arched and moaned and writhed. "Please!"

Sirius came more than he ever had before, filling Harry up completely, rolling them to the side so he could hold Harry to his chest until his knot went down.

Harry panted, a hand absently drifting down to where they were joined. Shivering.

Sirius held him tighter, moaning at the feeling of Harry's hand. "Go on sweetheart." He murmured "I might be able to come again." He thought out loud, just wanting to pump more into Harry.

Harry clenched around him, squirming a bit. Sirius rocked up slowly, not enough to hurt since they were still tied together. Sirius groaned, rubbing against Harry's prostate with each roll of his hips bringing him closer and closer. Harry suddenly gasped as he came again, trembling hard as he clamped down. Sirius groaned, leaning to bite on Harry's shoulder, coming just as hard as he did the first time.

"Nnnnnnfull" he moaned.

Sirius groaned softly, pressing kisses to where he bit down "wish I could keep you this full when my knot goes down" he admitted with a low growl.

"Mmmnh" he whimpered at the growl. "Fill me up enough and I'll stay full" Harry murmured.

"I think you've taken all I can give for this round, love" Sirius hummed, pressing more kisses.

Harry could only whine, leaning into each bit of affection,mind whirling.

Sirius nuzzled his face into Harry's neck, sucking lightly "you okay sweetheart?" He murmured softly.

"So full. Wanna stay so full"

Sirius pressed even more kisses, nipping at Harry's neck. "I'm going to keep filling you up love, don't worry. I've got you."
