penetrate Samantha

After a few more moments buried in her best friend's soaking wet pussy, Katie pulls her head back again. She blinks her eyes hard and licks her lips, as if she's trying to shake off the dive. Then she gives you a look, seeking approval.

You smile and nod giving that approval. Because, you really fucking approve.

"I thought you were just going to watch from the doorway." You ask teasingly.

Katie licks her lips some more. She can't get enough of whatever taste is on her lips. It sure seems like she's discovering a new favorite pasttime. She shrugs. She she shrugs her pert breasts and hard nipples bounce a bit. "It was too far away. And you were having too much fun without me."

Samantha writes a little. She's clearly eager to have a set of lips on her again.

"Do you still like the idea of watching?" You ask your girlfriend? She nods with a big smile. You know that smile. It's not just a giddy smile, it's a giddy and horny smile. "Up close?" More eager nodding.

You've read about couples who do this sort of thing all the time. Of course, you don't know any. Well maybe you do. But what you're thinking right now is about the stories you've read of couples who seem 100% kinkier than you could ever be, inviting others into their bed. Often times you read that they've set up rules and guidelines for their trysts. One of the most common being, they don't allow full penetration with their guests.

And you have this moment, as you stand up, and pull down your pants. You pull them down to your ankles, your pants and boxers in one quick go. Your hard cock pops out into the room for all to see. Samantha doesn't look. She doesn't notice what's happening. Her eyes are still closed and she fiddles at herself again until someone has the decency to return their attention to her wonderful red pussy.

Katie helps slip your pants off your feet. Anyway, you're having this thought about these people. Whose sex lives seemed like more than you could ever aspire to. And as you position your hard cock in front of Sam's wet pussy and slowly slip it in, you realize that with this one moment the script is flipped. They have threesomes but don't even allow fucking? What amateurs.

Back to reality. Katie gasps as your member slides into her best friend. Samantha gasps too. She lifts her head up to see you penetrating her.

"Holy fucking fuck!" She whispers loudly as she wraps her legs around your hips. You start to thrust.
