spilled some water

"Innocent Professor looks at Trix and nods" - Sure, I'm here to help you. What're you having trouble with?

"Innocent Professor seems a bit flustered as he notices how close Trix is sitting, quickly trying to maintain his composure" - Okay, "clears throat" what chapter are you studying? Maybe if you could tell me a bit about the topic, I can help you better.

"Innocent Professor tilts his head slightly to look at the book, but he gets a better view of Trix's cleavage in the process. He quickly turns his attention back to the book and clears his throat again" - Oh, I see. This is a very interesting chapter. Do you have any specific questions about it that you'd like me to help you with, Trix?

"Innocent Professor's face turns even redder as Trix leans in closer, but he tries to maintain a professional demeanor" - N-nothing is wrong, Trix. It's just a bit warm in here. Now, how can I assist you with this chapter?

"Innocent Professor's face turns even redder, and he seems quite flustered as Trix puts his hands on his thighs. He tries to move away a little bit" - Yes, yes, I'm fine, Trix. "He coughs" Do you perhaps want some water?

"Innocent Professor clears his throat and extends his arm to grab the glass of water on his desk, all while trying to avoid looking at Trix who is still in a compromising position. He passes the glass of water to Trix" - Here you go, Trix. "He takes a deep breath and tries not to let his embarrassment show as he waits for Trix to drink the water."

"Innocent Professor jumps as Trix spills the water on his crotch, feeling quite uncomfortable and flustered. He tries to push away Trix's hand from rubbing his crotch but doesn't want to cause any offence" - Uh... no, no, that's alright. You don't have to do that, Trix. Please take a seat back, let me clean it up myself.

"Innocent Professor feels quite uncomfortable with Trix rubbing his crotch, and he tries to push away his hands again" - Uh, Trix. Really, it's alright. "He tries to look away, feeling quite embarrassed and flustered."

"Innocent Professor tries to push Trix's hands away one more time, but he eventually gives up and sighs" - Fine, do whatever you need to do, but please make it quick. We still have to finish studying.
