Shoved against the wall in a rush of passion, Hagrid felt the tension leave his body and the blood in his body travel downwards.
He looked at Hedwig, worrying about why she'd flown in through the window and shoved him against the wall, why she was looking at him now with such animal need in her eyes. It soon dawned on him, staring straight into the lust in her eyes, that there was blood on his painfully-hard crotch where his lover straddled him.
Oh.
"Hoo!" She screeched, drawing his attention back to the tingling sensation—the warmth spreading, the feeling of her rubbing on him in a slow, steady pattern.
He hastily reached down with one hand and made quick work of pulling his pants completely off until his cock sprung out from his underwear and made direct contact with Hedwig's bleeding heat.
"Aa-aaah," Hagrid groaned out, managing to steady her body on him better, thrusting in and out as she closed her eyes in ecstasy.
Hagrid takes care of a lot of dirty business at Hogwarts. He looks after things no one cares for and loves them for all their imperfections.
Despite being a lover of all things odd and even disgusting, he'd never imagined he could like anything out of the ordinary, sex-wise. He shouldn't be so into riding Hedwig while she bled all over him, making an already messy situation more likely to stain, but he was. It was like that old saying about the crimson tide and riding it.
He was riding the crimson tide.
This brief train of thought was soon cut off as he felt the need, the absolute requirement to let go of the force building within his ready member.
He pushed in one last time—as hard as he could—and came inside her, reaching an acute pleasure he had never felt before.
After she got her fills and came on him, she dismounted from his worn penis. Hagrid clumsily reached for a dishrag and wiped the blood and other fluids tenderly from his lower body.
He and Hedwig looked at each other with heavy eyelids, overcome with strong feelings of bliss, and turned to collapse on Hagrid's chair, falling asleep, owl cradling half-giant.
