Send Lorelei whilst Johanna tips you

You check that Lorelei knows where her tute-partner means and tell her to go and collect a few stalks. She immediately (and gingerly) lowers her stiletto-clad feet to the ground and with much sniffling and whimpering, removes her throbbing bum from the table. She picks up her tiny skirt, preparing to put it on, but you interrupt her.

"What are you doing?"

"I'm, nuh, getting dressed to, uh, go out, Professor."

"Did I tell you to do that? Leave your skirt and you might as well take off your blouse too, while you're at it."

"Oh, yes, Professor. Mmn, I'm sorry."

She folds her skirt again and then undoes the remainder of the buttons on her blouse and shrugs it down her arms and off, releasing a round pair of alabaster tits that look even bigger against her slender frame. Even without the support of being crammed into black silk, they don't droop and the pink nipples point slightly upwards, surprisingly erect despite the warmth of the day. Whilst neatly stacking her clothes on the table, she seems to contemplate saying something, but thinks better of it and, picking up her brush, turns towards the door, sending her boobs swaying gently with the movement. When she reaches the exit, she hesitates for a moment, trying to decide whether to cover her body as best she can with her arms or try to act naturally. Eventually, she opts for the former and leaves with her right arm inadequately trying to mask her oversized chest and her left hand containing her brush held over her crotch. Nothing can hide her blazing bottom and thighs, though.

Turning to the Asian fresher still sitting on your table, you see that she has her eyes focused on the floor, a becoming pink blush covering her face and reaching as far as the tips of her ears. Surely seeing another girl naked can't have caused that reaction; she must have witnessed many punishments since the start of the academic year in which the miscreant had to expose her breasts. You ask whether anything's wrong, but she replies in the negative, blinking away the last of her tears.

You walk up close, placing your hand on her thigh, fingers brushing the welt from the extra swat you gave her there and causing a sharp intake of breath. Sitting on the table, she's tall enough to look you in the eye, which she does.

"Whilst Lorelei runs her errand, I'd like you to tip me, Johanna."

"Oh, right away. Would you like cash or a bank transfer?"

"Not sex?"

"Er, I assumed you would've kept Lorelei here if you wanted that."

"Why?" you ask, wondering for one awful moment whether you're having an affair or something equally inappropriate.

"Well, because she has much more experience with men than I do, what with me liking girls."

Belatedly, the Rulebook's powers supply you with the knowledge that in this reality, you were already aware that Johanna is exclusively lesbian and is dating casually, but without a steady girlfriend. Suddenly, her reactions throughout the tutorial make more sense. Another question comes to mind and when you don't receive any inspiration from the Rulebook, you assume that even in this world, you don't know the answer.

"Have you never been with a man?"

"Oh, yes, Professor. Even girls confident in their preferences for girls need to learn the basics of pleasing men. It goes to show how important it is for young women to receive guidance from older men."

"How so?"

"Well, when my neighbour first offered to teach me how to service a man sexually, I didn't understand why it was so important, but I knew it must be, because he said so. Then today, the tipping rules came in and I could get into real trouble if I hadn't practised before, so it proves older men always know best."

"That's right. Now, I realize tipping with sex wouldn't be your first choice, but I became very aroused when punishing you and Lorelei, so I'm going to need you to help me out."

"Of course, Professor, I completely understand and I would be honoured to show my gratitude in any way you wish."
