Jacob just sees a cheap whore, and fucks you like one

Jacob steps up behind you, the darkness of the theatre and the obscuration of your face apparently enough to keep him from realizing that the naked, well-fucked girl in front of him is his girlfriend.

You hear the familiar sound of a condom package being opened and roll your eyes. At least it isn't just you that he wears condoms with.

Except - you realize as he lines his thick dick up with your tired pussy - that he is with you, even if he doesn't realize it.

You stiffen as he begins to push. The last hour seems to have loosened you up considerably, but at the same time your insides have been battered and bruised, making them extra-sensitive and swollen. Fluids from past fucks ease his way.

"God she's loose," he says, and indignation flares within you again. You open your mouth to give him a piece of your mind, snapping it shut again as he pushes and you remember that he can't ever know that it's you he's fucking.

His thick log pushes relentlessly into you, shoving in without regard for your own pleasure. Quickly he begins to thrust in and out, not bothering to go slow, opting instead to use the cheap skank in front of him like she obviously likes. In and out from tip to root, he's soon slamming into you and you find yourself responding.

As the two of you meet, you pushing back and him forward, you realize that this isn't you fucking your boyfriend or him fucking his girlfriend. This is him cheating on you. And you cheating on him.

Confusion fills you, along with hurt and shame. Has he cheated on you before, fulfilling his need for cheap whores with girls other than you? Should you be angry? Guilty?

Your body doesn't seem to care what the situation is as it comes to life on your boyfriend's cock.

Jacob reaches forward, and you gasp. One fist twists in your hair before yanking your head back hard. The other fastens on one small breast and both squeezes and pulls, seeming to crush the sensitive tissues as he tries to drag them away from your body.

From the corner of your eye you see him lean forward, and along with the certainty that he'll recognize you at last comes another hard orgasm, making your body shake and cry out.
