Along the way...

As you race back to your room, eager to get back to business with Sam, you pass by your sisters room, her door partially cracked...

Normally you wouldn't pay it any mind, least of all now of all times, but as you pass you hear a slight whimper coming from inside...

"Oooh... John... Just like that..." You hear very softly...

Your ears perk up and your eyebrow cocks as you approach the crack in the door...

Your eyes open wide as you see your sister sprawled out on her bed, her legs split giving you the perfect view of her tight pussy, one hand grabbing her large tit, the other shoving the dildo you saw under her bed in and out of her pussy with a vengeance...

You can't help but stop and stare in wonder at this gorgeous sight before you...

"Just like that John... Fuck my tight pussy... Fuck it with that big cock..." She moans out under her breath, just loud enough to hear...

If your cock wasn't hard before it certainly is now...

You decide to move on, not wanting to leave Sam waiting and changing her mind...
