When the light flicks on, you hear a gasp and are briefly blinded, but you eyes adjust quickly. Caught, mid-run in the middle of the room, is your girlfriend Zoe wearing only her pajama top. There is a look of utter horror and shock on her face, with her hand tightly cupped over her mouth. Her obviously, real dick flops between her legs, rapidly softening due to fright. Caught red-handed, her face flushes and she quickly tries in vain to cover her member with her hands. You sigh and motion for her to sit next to you on the bed.
She briefly looks at the door, and it seems she's about to bolt, but she changes her mind, and sits next to you, her face beet-red. "Stupid, stupid, stupid," she keeps muttering under her breath, and it looks like she's about to either cry or hyperventilate. You put your arm around her shoulder and she looks up at you with tears in her eyes. "Zack, I'm so sorry. I *sniff* should have known letting you come over here for a week was a bad idea. *sniff* I just get so horny when you're around. I should have known I wouldn't be able to control myself for a whole week." She makes no comment about the fact that she has a huge dick, as if that's not the weirdest part of all this.
Finally, she stops sniffling and calms down slightly. "You're not mad at me are you?" she asks meekly.
"No, just surprised. I wasn't expecting that. You should ask me about these things first."
"You're right. I'm sorry." She looks at you until you meet her gaze. "Zack, Will you, uh, would you be willing to, um, give me a handjob maybe?" she asks nervously.
"Wha- what?!" You're still not used to the whole "my girlfriend has a huge dick" thing, so you're still moderately shocked by this.
"Sorry, it's just, I get so turned on, being in the same house with you, my hormones go crazy and I can't sleep at all. I promise I'll return the favor! Or, if you're not ready, maybe we could jack off together?" She's getting excited. You can see her dick starting to grow and swell once again out of the corner of your eye. Maybe you could get used to the idea of Zoe having a dick. I mean, it's the same old Zoe, you've been going out with, right?
Putting aside your reservations you agree to...
