First, get Gwen to drink the cola

"Fucking shit..." You mutter under your breath as you set the can down and start moving your limp female self off the bed. You hold her in your arms and gently tuck her away into your closet, hearing her moan softly as you set her down and shut the door.

"I hope nobody looks in here..." You whisper to yourself before gathering yourself together, "Ok... I got this... I should get Gwen to drink this first to get that out of the way...."

You grab the can and step out of your room quickly, but run right into a pair of firm breasts, knocking you backwards.

"Hey watch it creep!" Gwen snaps at you as you knock her back slightly. Her eyes wandering around your body, her eyes narrow as she asks, "Why do you look like shit lil bro...? And where have you been all day?"

"I've... been out...." You stammer.

"Yeah well you should keep a closer watch on your girlfriend Lauren, she was hanging out here all day looking for you like a lost puppy..." She teases, giggling as she remembers what her and your father did with her.

"Oh. Her? I uh... I didn't see her." You mutter.

"Well you should keep a closer eye on her little brother... never know when someone will snatch that cutie up..." she teases before looking down at your hand, "What's that?"

"Oh this?" You ask, holding up the can of cola.

"Duh... what else would I be talking about...?" She snaps at you.

Knowing Gwen too well you reply, "Its my last can of cola... and YOU can't have it!"

"Really...?" She asks interested, not even liking cola but wanting it because it's yours. "Why don't you hand it over so I can check if its expired...?"

"Do you really think I'm that stupid Gwen...?" You snap back.

"Guess not..." She teases, stepping forward so she's so close her nose almost touches yours, her breath tickling your lips as she pouts, "But can I please have it....?" She asks softly, her hand running down your arm.

You shudder from her touch, making her smile deviously, "No... I... um..." your cock rising as her gorgeous bright blue eyes lock onto yours.

Distracted by her, she snatches it out of your hand and teases, "You really are a creep John... I mean seriously... don't you fuck your slutty girlfriend enough to stop lusting for your own sister....?"

"Shut up Gwen! I do not..." You mutter.

"Oh Bullshit! I see you there John... with your wandering eyes...." She snaps back, opening the can, "Anyway... thanks for the cola twerp!" She adds with a giggle as she wanders off.

"Well that wasn't too hard..." You think to yourself as you plan your next move.... knowing the next two steps will be much harder.

You look down the hall and see the door to your parents room is shut, your mom likely getting undressed to take a nap after work... a good opportunity to use the darkness to your advantage...

You also seem to have started a dialog with Gwen... maybe you could push her a little more while she drinks the cola....
