In your asshole

"In your asshole." You aren't sure if you're just trying to surprise the little minx, or if that's truly the thing most on your mind right now. Either way Hilda answers.

"Of course professor!" She squeals and hops off of your dick. Moving to lean over the bench beside you on all fours, pushing her beautiful butt up into the air for you. "I've been practicing" she says with an eticing wiggle, "but I don't know if I can take a cock your size just yet. My asshole is all yours to try though!"

You stumble to your feet, dizzy from the sex and heat, but determined to claim this little sluts ass. You steady yourself with one hand on her hip, while the other spreads her cheeps and starts to probe her pink starfish. She moans as you push a finger in, but you need more lubrication than that. You dip a finger into her still dripping pussy and start lathering her little asshole up. Judging by the sounds she's making Hilda is definitely into it.

Finally, when you can't wait any longer, you bring your still hard cock up and into position. Hilda jumps slightly as your cockhead touches her backdoor, but she enthusiastically pushes into you. It takes more force than you'd expect, but you manage to start shiving your way into her. Hilda groans and shudders, a mixture of pain and please. "Fuck professor. You're massive."

"Is it to much?" You say. You don't really want to hurt the poor girl, especially since you plan to use her nubile body plenty more in the future.

She turns her head back and answers your question in no uncertain terms. "Stick that big cock in me professor. Fill my asshole with your cum!"

With that settled, you throw caution to the wind and push on. If her pussy was tight, her asshole is like a boa constrictor, but the feeling is amazing around your cock. You grab two handfuls of her long pink hair, and use them for leverage to drive your cock the last few inches into her, until your balls slap against her pussy. Hilda lets out a scream like a banshee, as you start to draw in and out of her. She holds onto the bench for dear life as you fuck her asshole.

"FUUUCK! Goddess professor. Fill up my asshole! Fuck my little ass! Use your Hilda. I want it all. FUCK!" Her dirty talking grows indistinct as the pressure builds in your balls. Finally, you can't hold it back any more, and you explode pumping her ass full of your seed. Your cock throbs as wave and wave pushe out of you and into her.

The last thing you see before blacking out is Hilda, pink hair in disarray, leaking ass up in doggy style bent over a sauna bench, with a look of absolute bliss on her face.
