A/N: Set before the golden trio are let through Aberforth's sister's portrait, a bit OOC but what can you do?
"I can't let you through without some form of payment" Aberforth said, leering at Hermione over his glasses, his x-ray like gaze seemed to see right through her clothes. Hermione squirmed slightly, but stayed silent.
"What's your price?" Harry demanded, they didn't have time for this.
"Give me the Miss Granger for an hour or so, and I'll give you safe passage to Hogwarts"
"What?! No!" Yelled Ron.
"I'll do it." Hermione said quietly
"No you won't, this is insane! I won't let you –"
"Ron, we don't have time to argue, I'll do it Aberforth, just let them go ahead"
"Very well," Aberforth opened the portrait and let Harry and Ron through.
After they we're gone, Aberforth took out his wand and bound Hermione to the table behind them, face down, with her arms tied to opposite corners. She trembled slightly, but stayed silent.
"Now, my dear girl, we shall begin" He quietly muttered 'divesto', and all of Hermione's clothes vanished. Her body tensed at the sudden cold air against her naked skin.
Aberforth came up behind her and slowly ran his warm hands over her arse cheeks, then slipped his fingers down her arse crack to her slit, his fingers we're covered in her juices almost instantly.
He leaned over her, "You like this don't you, Miss Granger, being bound, being helpless to what I'm about to do to you"
All she could do was moan, because as he said this, he slipped a finger inside her tight pussy.
"So tight, so wet…" he muttered to himself.
He withdrew his finger from her tight cunt, then undid his robes and pulled out his hard cock. Hermione squirmed on the table, as he grasped her hips and rubbed his cock against her dripping pussy, as she squirmed more violently he slammed into her. She moaned out loud at the feeling of being so full. Aberforth picked up his pace, fucking her hard into to table, Hermione groaned at the sensation of being so full, then suddenly she came hard as he hit her g-spot three times in a row. Instead of cumming inside her tight wet cunt he quickly unbound her and shoved her down on her knees in front of him before slamming his fat dick into her mouth filling it with his cum.
After she swallowed his cum, he picked her up and waved his wand so all of her clothes we back on her body as if nothing had happened. Then he shoved her through the portrait hole without saying a word.
A/N: I saw there were no Aberforth/Hermione smut fics, so I made a little one ;)
