Sirius' reached out and ran his hands up and down her body. Hungry palms slid between her legs, and without being asked, Sirius manoeuvred them both such that the back of Minerva's knees caught the edge of his bed and he rested on his arms, above her.

"You may continue..." uttered Minerva, her composure now starting to fray.

Sirius moved his mouth downwards, licking across her stomach and then pleasuring her with his tongue until Minerva twisted and groaned. She spread her legs wide, and clutched at his hair, long strands tangling in her long fingers to keep him in place.

Now, it seemed as if she was close - but ever the mistress of earned reward, Minerva told Sirius to stop. "I want more of you."

Sirius rose, and climbed further on to the bed, looking at her flushed cheeks in hunger and pride. "Would you... would you go on top?"

Minerva smirked. "My favourite."

She spun and straddled him smoothly as he lay. Minerva lowered herself such the tip of Sirius' cock brushed her wet sex. He thrust up wildly to meet her, but Minerva knelt straight up again, leaving Sirius bobbing forlorn in the cold air.

"What do you say?" The enjoyment in her tone was obvious.

He felt desperate now, unable to focus. "...Please?"

"Please, what?"

Sirius groaned so loud it was almost a shout; his horny young dreams were all coming true. "Please, Professor."

Minerva gave a curt nod, and then sank down onto Sirius, hot and tight and so very ready for him. It felt beyond amazing. "Aaaaagh..." he exclaimed, unable to do anything other than to soak in the feeling of her.

"Come on then, boy." Minerva swatted his arse, and flexed her spine in challenge. "Show me what you're made of."

At that, Sirius' brain returned from fog to white-heat, and he began thrusting upwards in earnest, meeting Minerva's gyrations with delicious rhythm. They were both pretty energetic; Sirius felt his heart racing and beads of sweat collecting on his brow and his chest. Gods, this was fabulous.

Finally, she leaned forward and grabbed him, head down and back arched as the spasms ripped through her. With those contractions gripping him, Sirius hadn't a chance. He orgasmed with a shout, head tipped back and clutching Minerva's hips.

They stayed like that for a moment, riding the waves of release. Then, Minerva collapsed on her back, next to Sirius on his old bed. She was panting and grinning - wide and unguarded. "Fifty points to Gryffindor."
