Usually? Wait, no, it's gruesome but that's a perfectly valid thing to do in defense of one's life, and Lilian would be safe from it anyway, most likely.

(It probably isn't reasonable for so much of Lilian's feeling that Mayu is safe to come from the general impression she gets of her over telepathy, for all she knows you can lie through that)

She thinks she sort of already knew about places like that, in the back of her mind, but having them brought to her attention is probably good.

Lilian regenerates and can heal herself real fast if she needs to, she thinks those probably aren't too dangerous to her, but it's good for her to know which places she needs to rescue people from fast. 

Mayu coos softly and sends an impression of the safer local routes that duck around the less friendly and smart tentacle pits and the dissolving chambers. 

She squeezes around Lilian's cock a little bit, and presses in with goo between her legs a little and listens for her arousal.

The squeeze and the goo between her legs are appreciated. Her lust and the low, slow-building desire for another orgasm flare up slightly, and she has a bit of a harder time paying attention to the maps instead of just focusing on the pleasure. Lilian focuses through it to keep absorbing the information Mayu’s sending, her sense that this is important, valuable information still strong enough to overcome her hunger for more.

A vague fantasy begins to form in the back of her mind of Mayu somehow convincing her that the best way to learn is to have a bunch of orgasms, but she manages to cut it off before it distracts her too much.

A thought bubbles up in Mayu's pink head, and she sends it. 

How about we study and then I quiz you and you get an orgasm for every right answer?

She chirrups happily. That was a big complicated thought. 

Mayu has succeeded in convincing Lilian that the best way for her to learn is to have a bunch of orgasms.

Oh my goodness, that chirruping is so incredibly cute. Lilian leans in to kiss Mayu on the cheek this time.

Mayu tastes of strawberries, it turns out! And she's very eager to review the maps. 

One route at a time?

She starts showing Lilian the route north, since that's the one that she's most likely to need to use soon.

One route at a time.

Lilian musters the full strength of her will to focus through the three great distractions of strawberry flavor, excessive cuteness, and snugglefucking. She mostly succeeds. For now, at least.

Lilian has a good memory, and her general method of navigating in her head is rather receptive to the visuospatial way Mayu’s explaining things to her.

Mayu isn't trying to make this difficult, but she sure is still squeezing and grinding against Lilian's cock. Not particularly urgently, but definitely some. 

They can do a few different routes this way, Mayu leading, Lilian following along. There's a lot of material to get through, though.

Lilian focuses on the routes as well as she can, trying her best to stay focused, to pay more attention to the routes than the sensations. Slowly, as time passes, the pleasant squishy feeling of Mayu’s body against hers and the slick tightness of her pussy around Lilian’s cock loom larger and larger in Lilian’s mind.

As time passes, Lilian asks Mayu to slow down or go over something again more often, each time her thoughts tinged with more arousal than the one prior.

Mayu notices the building arousal in Lilian's mind, and...

Well, normally she'd speed up, but for this case, it seems like the opposite would be a good idea? So she learns better? 

She slows down her pace along with the instruction, but does not, actually, stop. 

That helps in the short term. Lilian starts receding from orgasm instead of moving towards it. She’s no longer having her need to orgasm impinge on her thoughts enough that she has to, for example, backtrack because she just thought to herself that the correct way to get back to the surface at a particular junction is to cum in Mayu’s pussy.

(That was only once!)

Lilian is, in general, a quick learner. But then again, there is a lot to cover here.

That's no good! Lilian is getting less yummy!

She speeds up a little again, trying to aim for something in between where she was and where she is now. And keeps sending maps. 

She is maybe also being a little enthusiastic about a particular tentacle pit that she spent six months in a while back and still misses. 

Oooh, Lilian likes it when Mayu speeds up a bit again. Just how much she likes it takes a while to impinge on her ability to absorb information quickly. The description of the tentacle pit and the increased stimulation do eventually combine to the point that she starts to struggle a bit more again, though.

Maybe Mayu could slow down a bit when Lilian starts doing poorly, and speed up again if she’s doing well? To keep Lilian nice and yummy while she still manages to learn things?

This seems like a reasonable compromise! 

Mayu will settle for a nice simmering Lilian as they continue to review.

This particular feedback loop, incidentally, ties Lilian’s pleasure to how well she’s receiving Mayu’s instruction.

For a very horny Lilian, this turns out to be incredibly motivating. She wants that ooey-gooey slick hole to keep pleasantly squeezing her cock. She wants Mayu to keep bouncing bouncing nice and quick so her boobs jiggle in Lilian's face. So she needs to pay very close attention to everything Mayu’s sending her. If she doesn't, Mayu might slow down!

It doesn’t actually help her do better than if she wasn’t being distracted at all, but given some amount of distraction, this is probably the best-performing Lilian you could get.

She’s probably developing a new fetish. Well, she can add it to the list of new things she gets to enjoy since she landed in her new universe.

Mayu is enjoying this too! Is this... edging? She had heard of it from a traveller once, but never really seen the point of it before this. 

She's learning things! And so is Lilian. 

It is edging! Lilian has sort of complicated feelings about this! On the one hand, this feels great, holding back from orgasm for this long is driving her to exquisite levels of arousal, neediness, and pleasure. One the other hand, at least half of her mind is now dedicated to how much she wants to cum! Fortunately for her performance and her continuing pleasure, this is just driving her to ever-more-obsessively focus on learning everything she can!

After all, once Mayu moves on to quizzing her each thing she knows is a potential spurt of cum into Mayu’s pussy. She wants that, she wants it so much, whenever she gets too distracted it's always to giddily fantasize about her last orgasm inside Mayu, about cumming in her again.

Awwwwww, it's cute how brightly she shines when she's teased. 

Eventually (and my, is that ever a long eventually), it's quiz time. 

Mayu brings Lilian just up to the edge, and then asks her first question: Where is her favorite tentacle pit in this whole area?

Lilian remembers this! Mayu spent a while talking about it! Remembering the location is slightly difficult through the fantasies of all the lovely things it could do to her, but she manages! She got it right! She's sure of it!

She's gonna get to cum, oh yes she's so happy she's gonna cum, gonna go spurt spurt spurt into Mayu's sqeezy-tight pussy-

(If Mayu's paying close attention to Lilian's light, she might notice that Lilian's certainty that she got the right answer and Mayu's about to make her orgasm is very nearly enough to push her over the edge on its own)

And Mayu speeds up and clenches hard around Lilian, and kisses her with her strawberry lips, and bounces those tits in her face just like she wants them - 

And Lilian finally, finally gets to cum.

It’s everything she dreamed. The sheer pleasure of it would be overloading her, if she could still be overloaded like that. She can’t, so she gets to enjoy each and every spurt with a clear enough mind for it to seal itself into her memory.

This time her fantasies all stay put and she simply giggles happily as she her cock spasms in ejaculation again and again and again, compulsively thrusting up into Mayu's bouncing form with each spurt.

Mayu chirrups appreciatively, and, before Lilian can come down from her first orgasm, puts to her another question. She seems entirely unfazed by the grinding of her hips.

Oh, she wants to answer this right so bad, if she answers right her orgasm keeps going.

The right answer is-

Spurt

No, focus, it’s-

Spurt

It’s-

Spurt

Lilian giggles as she cums.

Mayu sllllllooooows down, and repeats the question.

After her orgasm tapers off, Lilian has the sense, somewhere in the back of her mind, that maybe she could have focused through that, if she’d just tried harder. But focusing on the pleasure was just so much more rewarding in the moment that she didn’t try hard enough.

Well, if that’s true she’ll manage it one of these times.

This time, less distracted, she answers the question right.
