The female gym teacher investigates lewd noises

For quite a while, Anna just enjoyed getting eaten out, not ceasing her vocations, and smiling at Judy from time to time, who was still ceaselessly masturbating to this, with a concentrated expression. The moaning and the slurping sounds drowned out most other things they could have heard; especially the soft sound of footsteps on grass.

Anna was the first to notice the newcomer, as she entered her field of vision; with wide eyes she stared at Mrs Brown, a rather young and attractive gym teacher. Her gym teacher.

"Excuse me? I'm sorry, I don't mean to interrupt, but I just had to investigate."

Lilly, startled by the voice, separated her face from Anna's crotch. With love juices dripping from her mouth, she assumed the same deer-in-the-headlights expression that Anna had. Judy just looked up. She stopped rubbing herself, but kept her hand where it was.

"O-o-oh g-god, p-please don't... I-I-I'm so sorry..." Lilly sounded downright terrified, prompting Anna to try to comfort her by affectionately caressing her butt. Mrs Brown had a similar idea; she knelt down, first wanting to reach for the girls cheek... but then deciding to pat her head instead, while smiling at her.

"Oh don't you worry, sweetheart, it's alright! It's after class, you girls are hurting no-one, you're just having a little fun. I got worried when I heard those cries and then the moaning that wouldn't stop, that's all. Wanted to check if everything's alright back here. Is everything alright?"

After a bit of hesitation, they all nodded.

"And you're all consenting? Now don't just nod, I need to hear it clearly. Lilly first."

Absolutely embarrassed and a little confused about the situation, she tried to answer. "I-.. I consent?"

"With a question mark? Come on, be convincing! Tell me what you're consenting to."

"I..." She gulped, and gathered her courage. "I'm consenting to have sex with Anna!"

"Good job! Anna?"

She needed a moment to find her voice, but with Lilly taking the lead like that, it was a little easier. "I'm consenting to... to sex with Lilly."

"And I'm consenting to finger-fuck myself", Judy chimed in. Even at that, Mrs Brown smiled and nodded.

It was certainly a humiliating situation, to have a teacher catch you naked, sticky all over, in the middle of an intimate act. Now one more person had seen Anna's intimates, heard her moans. But it wasn't so bad this time, as she wasn't alone in her humiliation.

At least, it wouldn't have been bad, if the teacher had left it at that, instead of trying to help them.

"One last thing... what does worry me a little... you look a bit weary, Lilly. Are you ok? I know you sometimes have trouble keeping up in gym class."

"Uhm... a little, maybe... but I'm fine."

"She came hard about seven minutes ago, and then just went on eating without a break like her life depended on it." That earned Judy a hard look from Lilly. So she wasn't actually immune to her brutal honesty!

"I just, I... I wanted to return the favor! I don't care if I'm a little exhausted afterwards."

"Lilly...", Anna began, but she didn't know what to say. She felt genuinely bad that she had pushed the poor girl so far, while she herself had just leaned back and let her work.

"You know, Lilly... I don't doubt that you're good with your tongue", Anna could see her blush intensify at that, "...but maybe we need to think about why it didn't make Anna orgasm so far. What do you think, Anna?"

Now it was her turn to blush. This was really shaping up to be more humiliating than it had to be... "Well, I mean, I'm enjoying myself, it... it feels awesome. I think we were getting there..."

"Yeah, but what do you think could speed it up? And if it feels so good, why didn't you cum in the seven minutes, plus however long you've been at it before?"

Neither Lilly nor Anna could come up with an answer to this wildly intimate question. But Judy could, and like Anna had come to expect of her, she left no embarrassing detail out.

"Anna helped with sex ed, as a live model. We got to play with her for two periods, she got fucked with a dildo, and then we made her cum several times in a row, like, she was whimpering and trembling non-stop, it was crazy. We haven't counted how many orgasms that was, yet, that's our homework. Also, she had a vibrator up her butt."

At this point, Anna just buried her face into Lilly's ass, to avoid the gaze of Mrs Brown, who was now finally properly blushing herself. Just great; another person clued in on her absolute humiliation.

"Wow... so much action in one day. Lucky girl." She affectionately rubbed Anna's foot, the only non-sticky thing in her immediate range. It made her feel a tiny little bit better, weirdly.

"So, there we have it. She already got so much stimulation today, it's natural then that she has a harder time reaching climax right now. And then there's the other thing... Lilly, have you given any attention to... this spot here?" Anna couldn't see where she was pointing; what were they talking about?

"N-no... I, urm, hadn't really thought of that..."

"Why don't you give it a try? Gently, and with enough lubrication."

If that hadn't clued Anna in, then the feeling of a wet finger spreading her juices around her asshole would have made it obvious. Startled, she gasped; and once more, when the well-coated finger tried to enter her anus.

"Deep breaths, Anna. Or Lilly won't be able to give you what you want."

Give her what she wants, yeah right. First she talks about consent, and then they **** her to get anally penetrated. Reluctantly, she took a deep breath, trying to relax... and it went in. And the deeper it went, the more Anna realized, this really might have been what she needed all along.

"Oooh... Mmmmh! Aah! Ha! Mmmh! Aaah!!" She squirmed, she quivered, and she practically squeaked every time the finger moved inside of her. Judy, meanwhile, had resumed rubbing herself. The show went on.

"See? That sounds promising, doesn't it?" Mrs Brown seemed almost proud, having guided her student to please Anna anally. "I'll be going now, I trust you can handle the rest yourself. I'll make sure to leave the gym showers unlocked, you'll need them afterwards."

"Thanks, Mrs Brown", Lilly said, a new-found, honest admiration for her teacher apparent in her voice.

Then, she proceeded to finger Anna's asshole while eating out her pussy. And Anna loved it. She alternated between 'Ohgod's and 'Ohyes's, while kicking her feet so much that she dug up some of the grass. When Lilly was done with her about sixty seconds later, she was so spent that she was almost unresponsive. To questions she could only answer "uh-huh" and "nu-uh". When Judy came back from bringing her and Lilly's school bags - and some towels - from their lockers, she was at least strong enough to walk.

They just streaked to the gym, not caring if any teacher or other personnel could see them from the distance. As promised, the door to the girls locker room was left open, and with that, the showers.

For hours, Anna had waited for this moment; the hot water washing over her, taking the stickiness away, even though it had turned into a symbol of fun times instead of humiliation and degradation. Lilly was happy to help her shower, still not done being enchanted with the body she now had direct access to. Anna was happy to grope back, though. And Judy was happy to watch them. She had creamed her panties several times, and needed the shower just as bad as them.

When they were as clean as they were going to get while turning each other on, the girls dried themselves on and started to get dressed. Or at least, Anna would have gotten dressed, if there wasn't something missing.

"Um... my bag, with my clothes, is kinda... at the lost-and-found... don't ask."

Lilly giggled, surely imagining her own truth, but didn't insist on an explanation. Again, it was Judy who hurried off, after being given a description of the bag and what was inside.

And five minutes later, she returned, with Anna's bag, with her actual clothes inside! Was this really it? Was she finally going to get dressed again?
