The choice offered you is not all that appealing. Whether you eat Blaze or she eats you, it sounds terribly familiar. But you can't really figure out how to say no. Instead you ask "Which would you prefer?"

Blaze answers this by giving you a big kiss and laying down on the bed, her legs spread wide and her knees over the edge. "Just get down on your knees and you should be able to kiss my pussy."
Following her directions, you get between her legs, and down on your knees, and then lean forward. As she said, your face is now just above her warmth. Blaze pats you on the head and then forces your face down to her lips. "Now you can make me happy."
You start to do so, but pause when you feel Lillian grab your feet. Looking back, you can see she is starting to eat you. But then your head is turned forward again. "Back to eating me, darling." You comply.

Once again, you are surprised how sensuous being eaten can be. Lillian's lips are like a caress and the feel of tongue and throat no less pleasant. You once again understand how Rickie can enjoy being eaten. You are enjoying this greatly. And with that enjoyment comes a desire to give as well as you are getting. Your tongue and lips apply themselves with vigor to Blaze.
It is a race you win. Of course, you could argue you win either way. But you are the first to achieve that pleasant release. Not that Blaze is far behind in shuttering with joy. But the second round features your legs and hips being pleasantly devoured. And you are too distracted to give Blaze her due. Only well after you have climaxed a second time does she reach the heights.

As your torso goes down Lillian's throat, she is almost holding you in position to pleasure Blaze. Indeed, there is little of you left except the head when you manage to cause her final convulsive release, something that pleases you, and you count your own exploding into a thousand pieces as you slide down to Lillian's stomach as a proper reward.

Blaze seems to think you deserved it anyway. You can feel her giving Lil a happy hug. You don't catch what she says, but you do hear Lil's response "I'm glad too, but it's time to study. Pass me that book on the top of the pile."

A moment later, she is reading to you, quite loudly it seems. You tell her to speak softer, and then softer still. Noticing that you can still hear find, you ask for even less volume and find you can hear even the softest whisper she makes. Indeed, you can almost read her mind, at least enough to follow the text as she reads it. It's not as good as reading it yourself, but it at least comes close. So the work continues.
Eventually it is time for you to pass on. Lillian lets you out, and now you can reverse the situation, something Blaze finds a great idea. But you would prefer to study in your own room. Or maybe not. That might involve the overly friendly Blaze getting rather close to Rickie. Not that you are making any sort of claim to him or anything, but... well... No, nothing like that. Still, it seems best for them not to meet... tho not for that sort of reason.
