Ever since they introduced role playing into the relationship Sheldon and Amy have been insatiable. Tonight Sheldon anxiously waits, sitting at the foot of the bed. Waiting for Amy to come in the bedroom. Excitement tightening in his belly. He wonders what Amy has in store for him this time.

Amy tentatively steps out of the bathroom wearing her black wizard's robe. Amy points her wand at him and winks. Then she teases him by sticking out her shapely leg. That Amy knows he can't resist before quickly covering it up again. He stands up and walks over to her.

"Professor Cooper!" She says surprised. "I'm sorry you caught me out of my bed. I was just on my way to the library," Sheldon grins catching the thread of the game.

"Miss Fowler, you know you're not supposed to be wandering the halls at night alone. Even if it is for a noble reason. I'm afraid I'm going to have take some points from your house," He tells her crossing his arms.

"Oh please! I can't be the reason the Hufflepuff's lose the house cup! We're so close to finally winning this year," Sheldon snorts at the thought of Hufflepuff winning the house cup. Amy glares at him but continues. "Isn't there something I could do?" She asks biting her finger and looking at him coyly.

"I'm sorry but as brilliant a witch as you are. This deed cannot go unpunished. Still there might be something you could do. Even though you've been a very naughty witch," He tells her brushing her hair away from her face.

"You're right, I have been a very naughty witch," She tells him leaning into his hand.

"Very naughty, you're going to have to come to my chambers to receive your punishment," He tells her walking over to the bed and sitting down. Then he pats his legs inviting Amy over. She walks over to him and lays across his lap.

"I've never been in a professor's private chambers before," Amy tells him.

"I used to not let girls in my room. However, I'll make an exception for you," He teases her. Before smacking her bottom hard and making her jolt in his lap.

"I thought you brought me here to show me your wand?" She asks as he smacks her again making her gasp.

"Oh, I'll show you my wand," Sheldon says lifting up her robes delighted to feel she is naked underneath. "Oak, 10 inches, very rigid," He says running his hand up her inner thigh and growling at the discovery of how wet she was.

"Hoo!" She gasps as he lifts her off his body and throws her across the bed. Then he covers her body with his. He bends down to kiss her softly as he pulls her robe off, then his own.

"I think you've used a love charm on me," He tells her as he pulls away and gazes down at her intensely.

"Love charms are forbidden! You're my teacher, I would never!" Amy says scandalized as he bends down and kisses her again, this time very slowly and building in intensity. Leaving her breathless as he pulls away and brushes his lips against her ear.

"I'm not playing anymore," He whispers. "You have a powerful hold over me. If I didn't know any better I'd think you used the imperius curse on me. I'm so far from who I used to be."

"An unforgivable? You know me better than that," She tells him. As he takes her hands and holds them above her head.

"I know, still you are a tricky little witch who has managed to charm me completely," He tells her moving to her lips again. Then he kisses down her neck and across her collarbones and down her sternum.

"No more than you charmed me," Amy manages to squeak out as his lips kiss across her belly.

"Did I put a spell on you?" He asks his voice husky as he moves between her legs and he kisses her softly.

"Oh god, yes!" She cries out gripping his hair as he continues tasting her.

He only stops when she calls out his name. Then he moves up her body again and fits his body between her legs. Slowly he slides inside her moving gently until he fills her completely. At first he moves slowly and gently savoring the sensation.

"You can go harder. I want you to," She begs as he thrusts deeper inside of her. Moving out and repeating the motion over and over again until Amy is quivering beneath him. Then flipping her around so she is on top of him.

"Ready to take a ride on my firebolt?" He teases as she moves on top of him. He runs his hands along her thighs. Sheldon smirks as he teases Amy's bundle of nerves with his thumb making her buck against his hand and cry out. As quickly as he began he stops, making Amy groan. Instead he continues upwards to her breasts tweaking her sensitive nipples.

"I don't know if you can handle my broom work," Amy moans as she swivels her hips and squeezes him tightly with her inner walls making him gasp.

"You are an excellent rider," He groans as he grabs her hips and thrusts into her deeper. Soon they both find their release and they lay tangled and sated.

"What should we do next?" Amy pants. "It's your pick," She giggles as she feels his heart pounding under her hand.

"Do you still have your TARDIS?" He asks curious. Sheldon looks down at Amy when she doesn't answer him. She's typing quickly on her cell phone and placing it back on the dresser. "What were you doing?"

"I told Raj to get the TARDIS out of storage," Amy replies. "I never had the heart to fully get rid of it," She says shyly. As she buries her head into his chest and curls into him. He smiles to himself kissing her head and giving her a squeeze.

"Then I look forward to traveling through time and space with you," He says softly as he senses Amy has fallen asleep. And soon he drifts off as well.
