You would be a fool not to.

Ophelia leads you out the door and down the hall to the common room. Your hand in hers the entire time. Surprisingly, no other students are present. You suspect they are all in the dining hall or in their rooms studying.

"I told you I had a surprise for you this evening." She says light heartedly. As the two of you reach her office door, she turns and pulls you in for a quick kiss. "I hope you like it. I'm sure excited about it." She opens the door and leads you inside.

"Lock the door and meet me in the bathroom." She instructs, letting go of your hand befor prancing off.

You turn to lock the deadbolt on her office door and slowly make your way to her private bathroom. Curiosity and anticipation about her surprise has your dick thick with excitment.

"I told you no one had played with my ass before. I can't stop thinking out it." You hear her call out from the bathroom. "I was thinking we could take the ass play to the next step."

You round the corner into the bathroom and see Ophelia standing completely naked. She is holding what appears to be a hot water bottle with a long rubber hose attached to the opening. "I can't stop thinking about you playing with my ass. Doing more to my ass." She says biting her lip. "I enchanted this never ending bottle." She approaches you. Pressing her naked form against you. "When it comes to you, I'm a dirty girl. A very naughty, dirty girl." Ophelia kneels before you, lifting your shirt to expose your stomach. "I want you to help me." She kisses your belly. "I want you to cleanse me." She begins to untie your pants.

You don't waste time removing your shirt as Ophelia lowes your pants and boxers. "Ass play is my specialty." You respond confidently.

Ophelia smiles. "I was hoping you would say that." She hands you the bottle as you step out of your pants. She quickly takes your length into her mouth. Giving a few quick strokes with her lips bringing on your full erection before standing again. She takes your hand and leads you to the shower. Once inside she gives you a deep kiss befor turning her back to you and placing her hands on the wall. Ophelia arches her back to extend her ass towards you.

You slowly kneel behind her and take the tip of the hose in the fingers of your right hand. With your other hand, you grab her left ass cheek and pull it to the side exposing her tight sphincter. You aim the tip of the hose and slowly insert it into her ass. "I have never done anything like this before. Squeeze the bottle gently and slowly fill me up." She sits tentatively.

Once the hose is secured in her ass, you begin to gently squeeze the enchanted bottle. It is slightly warm but not hot in your hand. You can feel it's contents slowly flow down the hose and into Ophelia's ass. "Hhhhhhaaaaa!" She quivers as the warm liquid enters her rear.

You stand behind her, bottle in hand, and press your nude body against her backside. You rach your free hand around to cup her ample breast as you kiss the back of her neck. Your dick rises between her legs pressing against the outer folds of her slit.
