Make out with her

"I'm going to make out with her." Katie says. "I haven't kissed her in a long, long time, and I want my lips touching hers hers while you're making her moan."

Katie has always been a good sexual partner. She's never been shy. But you're still not sure you thought her capable of being so bold and dirty. She notices you reacting to what you just said.

"I don't think I've ever heard you say anything quite like that before." you explain.

"New and improved" she says. And you have heard her say that before. It's one of her sayings. In that you'd come home from work and there'd be some new piece of furniture or she'd have painted a wall some funky color and you'd be surprised and she'd say "new and improved." It's all part of the comfortable domestic life you're now leading. Except, of course, now your girlfriend is saying it referring to the threesome she's just orchestrated for you.

And just like that you're both through the door. It all happens so fast. Samantha opens her eyes, her fingers still working themselves inside her panties and gives the both of you a big smile. "You came back." She says.

"I said we would. Besides, it is our bedroom." Katie manages to to slip out of her jeans and walk up toward the bed at the same time. She's moving with an eager gracefulness, like something out of a dream.

"Yeah, but I didn't really think..." Samantha starts.

"Shhh." Katie interrupts. "Remember this?" And she kneels next to the head of the bed, and locks lips with her best friend. Their tongues dance together.

And you take your place at the foot of the bed. You're not sure what's more amazing. Watching Katie and Samantha kiss, or placing your hand on another girl's hips, peeling her panties down off her thighs, looking at the red tuft of hair above her wet, eager slit, knowing that your girlfriend approves of the whole thing.

You undress quickly, certain you lack Katie's grace, but not caring. You need to be naked. And within moments you are.

"You taste amazing" You hear Katie say to her best friend. Another phrase with more than a hint of dirtiness you'd never thought you'd hear her say, let alone to another girl.

Your cock is as hard as it's ever been. You grab Samantha's body and pull it toward you. Katie moves with her, the two keep kissing and looking at each other with adoration. Katie slides her hand down into her own panties.

"You taste great too." Samantha echoes, sounding a little nervous and a little overwhelmed by what's happening.

You agree. There's no way not to be overwhelmed by the moment as you hold your thick cock up to your girlfriend's best friend's pussy and push it inside her. She moans.

"I want to taste good for you." Katie says, glancing over at the sight of you penetrating Sam with a wild smile on her face. "I want to taste even better for you." Katie seems calmest, as if she's tapped into some naughtiness inside her that she's never known before, but fits her like a glove. She seems comfortable with how capable she is to do anything dirty.

And she does.
