Lick her own fingers and kiss Sam

Katie takes her fingers out of her underwear. They're glistening with juices. And in what can only be a moment of pure filthy inspiration, slides them between her lips, sucking her own juices off of them. Then she leans back in and kisses her best friend with her juice-covered lips.

It's a long lingering kiss with lots of tongue. "Mmmmm" Samantha lets out a moan, and you're unsure if it's because of Katie's kiss or your penetration. You pump your cock inside her steadily and softly right now. You don't want to distract from the moment she's having with your girlfriend. There will be plenty of time for passionate fucking later.

The kiss ends and Samantha opens her eyes. "How long have I been away?" She ask. "When did you turn into such a dirty girl?"

Katie smiles. Your girlfriend seems to have overcome her nervousness and she seems to have done so by simply embracing her wildest tendencies. "Five minutes ago." She answers.

New and improved, you think.

"Is that the first time you've tasted pussy?" Katie asks. Hearing your girlfriend talk dirty is always a turn on. Except in this instance it's contributing to your erection which is buried deep in her best friend.

Samantha smirks.
