They see you watching

You and Erica don't exactly have the presence of mind to be discreet at your 'peeping', so it's not long before Simon notices your stares, despite how 'busy' he is. And Heather follows his gaze shortly after.

They don't seem to mind you watching...if anything, you think they've gotten a bit more enthusiastic once they noticed your eyes on them.

Without stopping his hips, Simon grins at both of you. "You can watch," he grunts loudly as he gives Heather a particularly deep thrust, "from closer, you know."

Heather fixes Erica with a sultry smile, then you with something closer to a sneer, before addressing both of you. "Sex is better..." she lets out a moan as Simon pounds her in just the right spot, "...with an audience."

The two of them both beckon at you and Erica, urging you to move right up next to them while you watch. And you find yourself unable to avoid doing so...

You're not sure why, but the sight of their intense, bestial love-making is the hottest thing you've ever seen. After glancing at Erica and seeing that she seems as fascinated as you, you pull her with you to kneel on the floor next to the seats that Simon and Heather are fucking on.

From her, you can clearly see Simon's huge cock sliding in and out of Heather's pussy, revealing a full foot of fat cock, then ramming the entirety of it home into Heather's body.

The sight of just how much cock is fitting inside Heather's comparatively small body is overwhelmingly erotic to you for some reason...you can't look away as Simon fucks his woman in a way you'll never be able to emulate.
