You both go to your next class

As class ends, you both pack up your stuff and head together for your next lesson, philosophy. You were actually looking forward to that one. The classroom wooden and just under the top roof of the university, giving the whole room a medieval and comfortable atmosphere. Additionally, the only way to get there was along a steep, wooden spiral staircase. You made a mental note to some day ask a teacher if that staircase had been intentionally left alone after renovation works, or if they installed it just for the purpose of giving philosophy class its flair.

You and Ashley made your way there. Nothing eventful happened for which you were kinda glad as you were still coming down from the erotic thrill you just had before. Occasionally, you see a familiar face that you happily greet with a few words.

The spiral staircase was narrow and there were still a few people walking down, so you couldn't walk beside each other. Ashley went ahead of you, ladies first of course! You didn't actually say that, but you didn't mind her taking the initiative and walk ahead, already looking forward to have her big butt so close to your face in the next few steps.

As you walked up the staircase, you realize that Ashley must've never worn a skirt before. You can't remember ever having seen that much naked ass before. To top it all of, you could also see her dick obediently tucked inside. You were mesmerized by her glutes flexing and relaxing. Ashley suddenly stops walking and you're heading head first into her. Not quite realizing what's about to happen, you plant you face directly between her big cheeks. The surprise makes Ashley clench her ass, trapping you for a moment. As you exhaled just before bumping into her, you immediately try to take in air. Being trapped by a big amount of flesh tough, you start to panic slightly.

As Ashley relaxes her muscles, you pull away while taking a deep breath, inhaling her smell. This time she definitely smells less sweet and much more ..., you can't quite come up with a word for it. It's not smelly, doesn't smell like sweat or ass, quite pleasant actually. You lost yourself in your thoughts again. By now, the people who made Ashley stop walking have passed along while you're still standing directly two steps under Ashley, with one foot already one step further, positioning you directly behind her bottom.

Ashley turns her head around and sees you staring blankly ahead. Looking down the stairs behind you, she sees that nobody else is coming up behind you. She gets a little idea and decides to go ahead with her spontaneous plan. She places one foot on the next step 'to tie her shoe'. Then she leans her upper body forward, and her ass backwards, bringing it closer to your face. The movement takes you back out of your reverie and you grab onto the quickly approaching strong thighs. Being weaker and in an unfortunate position, you can't stop her and your face makes contact with her ass once more.

This time, you're much more aware of yourself and find that your nose is knocking on her backdoor. Her thin slip not doing much to hide anything. For the fun of it, Ashley clenching her butt cheeks again and stands back up, pulling you along with her. As she relaxes again, you can hear her giggle. You however can't help but turn red, both from the lack of air and from embarrassment. You both continue to walk up the the stairs, and for the fun of it, she abruptly stops again. But now, you stop and glare at her as she looks back to see your expression. Once you're up and in the room, she tells you that she's sorry and that she found it quite funny how you were trapped in her ass. You just answer with a deep grunt, but can't help and still feel aroused.

To your surprise, she Ashley then whispers in your ear, "and it even aroused me a little bit".

You stop walking and just stand there with your open mouth. You head turning even redder than before.

"Close your mouth, or somebody might become funny and put something in there", Ashley says and winks at you.

You're so taken aback that you're still not moving. The gears in your head grinding against each other, trying to figure out if you just had another daydream, if you misunderstood her, or if she actually said that. After some blinking, you look into her eyes and still see her seductively eyeing you, as if she were undressing you on the spot. That makes you move again, continuing the last steps towards your seats. Then and there you decide, that what you heard her say was actually real, and that you were happy to have heard it.
