Your girlfriend gasping

It's not just any gasp. You'd know it anywhere. It's Katie's. And it's the sound she makes when she's very, very happy.

You look up and see Samantha's tongue gliding over Katie's neck.

Katie's neck is one of her most acute erogenous zones. She can't control herself when her neck is getting attention. You've known this for some time. But you wonder if Sam knows it. Did she discover it during those make-out sessions in college or is she discovering it right now? How you'd love to know the explicit details of what went on back then.

But there's no time to care about that now. You have explicit details to create tonight. You can't help but reach down and grab your hard cock. You try not to jerk it too intensely.

But it's difficult to control yourself as Katie turns her face to stare at you at the door. Her lips are parted. Her teeth are gritted. She let's out a half moan-half whimper. Her bottom lip trembles intensely. Her best friend's tongue licking wildly in long strides all across her long, shapely neck.

Her plump b-cups heave up and down. Her nipples are piercingly hard. Her fists clenched. Her whole body is reacting to this moment.

Katie's expression calls out to you. But you're not exactly sure what she's trying to say. Does she want to be sure you're seeing just how much she's enjoying this moment? Does she want you to join in? Does she want you to know that she's about to melt right there at the foot of your bed?

You decide it's time to step into the room. So you do, swinging the door open and taking two steps toward the bed, standing there, naked, your hard cock pointing up at the ceiling.

Katie's expression doesn't change. Her lust-filled eyes are still glued to you. Samantha keeps licking, but you see her glance in your direction.

And you realize both girls probably expect you to do something.
