I walk in and find you jacking off while out parents in the house. I know you're a virgin so I decide to tease you by kissing your cock. I begin to suck your cock nice and hard, dirty talking to you throughout. I promise you no one will find out if we stay nice and quiet. I start to ride your cock softly and quietly so out parents don't here, but I can't help but moan loudly as your big cock fills me up. You cum all inside my sweet pussy and I lean right towards to so you can see the cum drip out of my pussy. I know brothers and sister aren't supposed to act like this but it's not like we're actually related, right?
