You were right to be suspicious

As you walk through the portal, you try to temper your thoughts of distrust. Siobhan may be a trickster and secretive, but she is not openly malevolent. She wouldn't be going out of her way to do something against Tyrlo just for the hell of it; she's not that vindictive. At least, you don't think she is. Her grandfather, who has wronged her, certainly, but she's actually trying to help this young lady put her feet back under her, and set her on a new life. As your eyes clear of the shifting blue light of the portal and you begin to see where you have been transported to, you see that your impression of your teacher wasn't entirely correct, and you had every reason to think that she was up to something.

You had been taken to a college, that much was immediately evident. The buildings were impressively tall and built of dark stone bricks, that show their age and weathering well. Banners hang from the rafters in pleasing colors, with musical instruments and other lovely symbols printed on them, so this was presumably a bard's college, as promised, but something was off. There was uncomfortable warmth and humidity here that gave you a desire to just remove all your clothes, there was a pungent odor that pervaded your nose, and you could hear the unmistakable sounds of rhythmic slapping and moaning.

"Verigas?" Tyrlo asked, holding her head as she started to feel strange "Where are we? This doesn't look like any Bard's College I've ever heard of. I have no idea where we are."

"I do" You reply shortly. You take her hand this time, as you leader to a window, looking into what would normally be a large lecture hall. Inside, there were rows and rows of desks, with a naked woman over each of them, all getting fucked in their assholes. Tyrlo stands besides you and looks inside as well, and is immediately flustered.

"Oh my God!" She calls out "I don't understand. Where are we? What kind of college is this?"

"This is the Bard's College in the Plane of Lust."

"The what?" She asks, "But, there's no such place"

"There is," You recount "Siobhan sent me here once before. Of all the Bard's Colleges in all the worlds, why would she choose to send us here?"

You hear a strong, deep voice behind you, and you both spin around to see "Because you can never beat the original" The man was large and strong, with considerable hair all accross his body. His manhood was thick and impressive, far larger than yours, and glistened in what you can only imagine is the body fluids of someone he just fucked. Tyrlo was fascinated by its size and girth. The only clothing he wore was a cap typically worn by dean's and esteemed professors. It was in fact the first and only time you've seen anyone on this plane with any clothing at all.

"You mean to tell me that this is the first Bard's College ever?"

"Why is that so hard to believe?" He asked, as he gently took Tyrlo's hand and pulled her close "A bard's job is as a pleaser and as a performer, and the first performance art in all known history is the performance of sex."

"You mean prostitution" Tyrlo responded with what you were thinking. Though she was unsure of this, just as you were, her mind was already adjusting to the subtle intoxications of this land, very slowly and unconsciously disrobing herself.

"No, I don't" He responded with a sincere smile "That is such an unfair and rude accusation. We perform for our lovers all the time. We moan louder to inspire them, we stare into each others eyes to communicate our feelings. We play parts in the bedroom different than ourselves to satisfy the desires of others, as well as our own. Prostitutes may be professionals at it, but they are not alone in it, and they certainly shouldn't be judged for it." By this time, Tyrlo had stopped fidgeting with her robes, and started stroking the massive dick in front of her.

"Hey" He said in his smooth voice, looking down at her "You know, you're really pretty."

"Thank you." She replies, staring at him as she continued to give him a handjob, not even aware of what she was doing.

"I take it you're the one that wants to be a bard." As she spoke, he moved his hands in an arcane fashion, and her robes simply fell through her onto the ground. Tyrlo didn't even notice.

"Yes sir" She said simply in reply, as if being enchanted.

"Oh, no need for such formalities. Why don't you tell me you want to be a bard?"

"Well, because I saw them a lot when I was a kid, around my dad." She let out a small yelp as she felt his hands grope her chest "They always seemed to make people so happy."

"You like making people happy? He asked, to which she just nodded.
"You like making your daddy happy?" She nodded again
"Well, I'll be your daddy now, see how happy you can make daddy..." Without another word, Tyrlo dropped to her knees and began sucking the dean's engorged cock. Devoted but amateur, she could only manager to fit the head, but both of them reveled in the moment.

"Ya...I can see that." He replies through a moan "You definitely have the right attitude to be here."

Repulsed, or perhaps jealous, you start to turn away, putting your hand on your ring, about to pull it away.

"You know, there's no reason you can't stay here too..."

Angrily, you turn back to address him "Thanks, but this is not my concern. I'm a wizard"

"Well your eminence," He replies sarcastically, "I imagine you haven't met too many bards in your life, because they use magic, just as you do. You could learn quite a bit if you chose to stay..."
