Smack Katie's ass hard

The sound of Samantha's hand slapping your girlfriend's ass echoes through the room. Your mouth drops. So does Katie's.

"Hey!" she shouts playfully looking back at her best friend. In 6 years of sex play, you've learned that Katie isn't the biggest fan of things like spanking and slapping. But at this moment she doesn't seem to mind it. And you don't mind that suddenly she's not minding it.

"That was for not letting me cheat off of you on our 10th grade chemistry final" Samantha says proudly.

Katie shakes her head to herself, as if she can't believe the behavior of her best friend.

And Samantha responds by giving her ass another slap, just as loud as the first one. "That's for the time you refused to share your bottle of Wild Turkey with me at our graduation party."

Katie laughs. She laughs at Sam's playful pettiness, remembering all these moments. She laughs at the silliness of the sound of an ass being slapped. She laughs at the ridiculousness of this situation. Her best friend, naked on the floor with her, is spanking her for past transgressions.

And she gets another one. "And that's for the time you refused to share your boyfriend with me." Samantha laughs.

"Hey" Katie's not having this one. "What are we doing right now?" She insists.

"Yeah... six years later." Samantha responds with a smile. "Now are you gonna lick me or what?"

Katie's face is still positioned to just lean down and bury itself in Sam's waiting pussy. "I'm gonna bite you down here." Your girlfriend jokes. Samantha lets out a huge laugh. Then Katie nods her head at the door. "And when he gets in here, he's gonna let you have it."

That's your cue. If anything called for you to step through the door and make your appearance, that's it. So you do. Naked, hard, ready to go, you step into the room. And both girls look in your direction.

Katie smiles at the familiarity of your naked body. Samantha smiles at the first sight of your naked body.

And you realize both girls are waiting for you to do or say something.
