Katie

You see Katie glance at her best friend's glorious wet slit. This must be the close she's gotten to another woman's pussy before. At least outside of a shower or something like that. This must be the closest she's gotten with the intent to interact with it in this way.

You nod at her, indicating that she should indeed interact with it in that way. And she takes a deep breath and nods back, eager, and nervous, as you scoot out off the way an help guide your girlfriend's face into her best friend's wet twat.

It's an amazing sight, watching her lick at it with joy but uncertainty, trying to find a good spot, a good rhythm, a good technique.

Maybe it's because you've watched too much porn, or because you've assumed that a girl would just naturally know her way around another girl's anatomy, but you're somewhat shocked at how timid and careful Katie is being. But you have to remind yourself that she's never done this before. She's a novice. Right now, you're looking at something new.

And being the nice guy that you are, you decide to help.

"Just keep at it" you whisper. "lick at her clit over and over like a cat licking at milk, that keeps vanishing so you need to lick deeper and deeper." you try to explain, feeling a little foolish. But also knowing that at this moment you're teaching your lovely girlfriend how to lick another girl's clit. And that's amazing. You place your hand on the back of her head, holding it in place against Sam's body. "Don't worry about being repetitive." you say.

Katie pulls her head back for a moment and smiles. Her chin, too, is covered in Samantha's juices. She gives you a goofy smile, as if to say she's doing her best, she feels a little awkward, but she's happy. You know her looks pretty well.

"Dear fucking lord." Samantha says in a panting voice. Katie covers her mouth with her hand, as if to suppress a giggle. Then, proudly, knowing she's doing alright, buries her head again.

And since she's doing alright, you decide it's time for you to do something else.
