Go into Shana's mind.

Shana, though still perplexed, is too consumed by lustful comfort to ask anymore questions. She decides to worry about it later, and just bask in the ecstasy and the wonderful sense of being worshipped. Her pleasure makes it easy for you to slip into her mind as well. Already you've been picking up her thoughts and her feelings along side Haruka's. It isn't too much of a leap to acquire her senses, too.

Oh, it feels so good, Shana thinks to herself. She gets hornier just watching her girlfriend's face moving up and down between her thighs, let alone feeling the actual effects of it. You can feel it too, as if the girl really is kneeling in front of you, licking your hard penis all over its body.

Oh, good, good, so good, Shana thinks some more.
It can feel even better, you suggest.
What? Shana shows the same befuddlement that Haruka had.
Open up your lips for your lover, so she can really eat you out.
Open my lips?
Yes, for your lover. It will feel so good. Do it.

Not having to fight any kind of bashfulness, Shana makes way for your push without hesitation. For my lover... it will feel so good, yes... And so she leans back on the toilet and with each hand, pries open her lips for Haruka to see.

On her first glimpse of Shana's insides, Haruka actually emits a tiny bit of digust. She rears her head back at the sight of the soaking red flesh.

Remember Shana? Do you remember what she has done for you? you push, regardless of the fact that Shana really hadn't done anything in particular. You do remember, don't you?

No, I don't remember--
You do remember. You showed your appreciation, right? You must have remembered then.
Yes, I was showing my appreciation. I remember now. The logic is ridiculous, but passable for the mentally-compromised subject.

But it wasn't enough, you tell her, she needs more. She needs to feel good, and you want to make her feel good. So do it. She'll love it, so you'll love it, too. You'll love the taste, as well, because you love making her feel good. Now lick her insides.

A moment later, the girl places her mouth back on Shana's snatch, filling it with her tongue as deeply as she possibly can. Shana can't help but scream out, loving the sensations so much she squeezes Haruka's head with her thighs, not that she would try to escape. You've seen to that. In her mind, she savors the taste of her partner's salty juices, which taste to her like whatever it is that she thinks great tasting pussy should taste like.
