A Soulmate's Kiss

Chapter 1

Harry woke on his 18th birthday with a gasp, writhing against the sweat soaked sheets from the dual sensations of his 'Majority Power Growth' settling into his core, and the rampant arousal that swamped his system. Oh, make that his boxers too. He groaned in confusion, tossing and turning before finally slipping a hand into his boxers, gasping as his fingers came back wet.

"Wha?" he groaned, hand going back to trace along his cock and the rim of his hole, moaning loudly. He had no idea what was going on, just that he felt so bloody EMPTY.

Sirius was doing dishes, the muggle way, just to piss his mothers' portrait off.

Harry was late coming down this morning so he decided to go check on his godson. Once the dishes were done he put them away in the drying rack and made his way upstairs. Once up there Sirius knocked softly at Harry's door.

Harry cried out in shock at the noise, his nose flaring as a spicy warm scent hit it. Why was he smelling it? Where was it coming from? He moaned, grinding back against his hand, moaning louder when a finger slipped inside. Tossing his head back, he promptly forgot about the doorknock. Surrounding himself with what little of that scent he could get as he edged toward release, even though he still felt so EMPTY.

Sirius frowned. "Harry, are you alright?" He asked knocking again.

"Sirius!" Harry groaned, flipping onto his stomach, pushing up on his knees when that postion just felt RIGHT. "Fuck. What..." he moaned loudly, his head tossed back as he found his prostate.

Sirius' frown deepened, opening the door. "Harry, wha-" He stopped dead in his tracks. "Shit! I'm sorry!" He blurted out, stepping out of the room and closing the door behind him. The smell was too much, he was thoroughly dizzy.

Harry whined high in his throat, having a passing thought that he should be embarrassed but it was pushed away for later by the unbarable NEED to have that scent back.

"Fuck." Sirius groaned, forcing himself down stairs and into the sitting room. He made his way over to the firewhiskey, pouring himself a whole glass and flopping down into the nearest chair.

Harry writhed and moaned, working up until he was slamming 4 fingers into himself as he came with a shout.

It was as the heat and hunger wore off that embarrassment and confusion took over, pushing him into the shower. He felt weak and worn out.

Sirius finished his drink and forced himself back up the stair to check on his godson. He knocked lightly, "Harry?" He called, not opening the door this time.

Harry pulled open the door since he was dressed, his face dark red. "What was that?" He asked, feeling a bit weak still.

Sirius just smiled at him, pushing the awkward encounter earlier to the back of his mind and hugged Harry tightly. "No one has explained this to you? You're an omega, Harry."

Harry hugged him, back, his nose buried in Sirius' shoulder. Mmmm, that scent was here! Wait. "I'm a what?"

"An omega." He repeated "Its a sub-gender. You come into it on your 18th birthday." Sirius explained, just holding him close. "You can also find your soulmate now."

Harry hugged back tightly. "Soulmate?" He blinked. "Omega..."

"Yes, your first kiss with someone will determine if they're your soulmate or not. If you're destined to be with them." Sirius explained. "Omega" He repeated "There are three sub-genders Alpha, Beta, Omega."

"Okay." Harry nodded a bit, watching Sirius.

Sirius gave him a smile. "Questions?"

"A lot." Harry admitted, a bit dazed.
