Join her

You watch captivated as she continues to fuck herself with the rabbit while stroking her dick. Your own cock is sticking out proudly against your boxers. Suddenly Jade moans loudly and says your name again.

"Oh god bro, fuck me! Fuck me! Put that big cock in my pussy! Give it to your slutty sister!"

That made your mind up. You removed your boxers revealing the biggest erection you have had in years. As quietly as you could you entered Jade's room, closing the door behind you.

You crept your way to the bed. As you reached the bed you obstructed the light coming from Jade's bedside table lamp. As a result a shadow is cast onto Jade's bed. She opens her eyes to see what has caused the sudden lack of light, only to see you standing above her completely naked, rubbing your erect cock while watching her masturbate. You see the shock in her eyes as she takes in the state of this predicament.
