So far so good as the mysterious stranger slips into the darkened room

As soon as the door opens it closes again, giving you only a glimpse of a male body. From down on the floor you can't be certain but it looks average in height and build. With the lights out you can't see the man's face.

"Turn on the video, Jenny, I want to see you as I fuck you," Jacob says, his loud enthusiastic voice making you wince. A chuckle tells you the interloper heard, but you can't figure out what to do. If you yell at the newcomer it'll tip off your boyfriend and the lie might be exposed. But if you don't...

A hand touches your hip, making you gasp in shock.

"No fair starting without me," Jacob says, misinterpreting the sound.

"I... no... I mean, we shouldn't..." you try to say as the hand wanders around on your oil-slick butt. If you can get Jacob to call it off - without annoying him - you can escape from this man molesting you.

"You're not going to leave me like this, are you? I'm hard, I'm naked, and I even grabbed some baby oil."

"Baby oil?" you can't help but say. "Why do you have baby oil?"

"Uhhhh...." he hedges, and you sense you caught him on the verge of an uncomfortable revelation.

A finger chooses that moment to poke your tight rosebud, the slick wood oil slathered across your body making it easy for the digit to worm its way into your virgin backdoor.

"Oh! My anus!" you exclaim, unable to bring yourself to more vulgar terms.

"Oh thank God," Jacob groans. "I was afraid you'd be disgusted. I've wanted to make love to you in that way for so long now..."

"My... my butt?" you say in a squeaky voice, reaching back to swat the hand.

The man molesting you ignores you, and gets a fingertip inside of you. At the same time his other hand has found your clit and begins to rub on the recently aroused nub.

"Oh," you groan, the remnants of your previous passion returning.

"I want to take you there, Jenny, I want to plant my long, thick pole up your... ass," Jacob says. Like you he's not used to the vulgar words, you're sure. He's always been very proper, just like you have.

You've heard various girls saying how two-faced their men can be, speaking respectfully in front of them and then saying all sorts of filthy things when they weren't around. But Jacob wasn't like that, you were certain.

"Oh!" you exclaim this time as the finger leaves your ass, only to hear an unzipping sound. Your eyes go wide as something big and spongy rubs against the space between your pussy and ass as if it can't make up its mind where to go next.
