Upstairs you go!

You moan as Piper's thrusting becomes harder and faster. Before you know it your being sent over the top in a vortex of orgasms. You push Piper up off of you and grab her hand.
"We're gonna have some fun in my room." Standing up, you can feel Piper's **** to wait but urge her up the stairs. 'This is going to be fun'
Leaving the door open, you push Piper on the bed and remove you top letting it flutter softly to the floor. Your breasts sway as you reach down o remove your shoes and them skirt as Piper removes her clothing. You aren't surprised to see your sister's nearly flat chest compared to yours. It's not like the first time you've seen her naked. But is is the first time you've wanted her sexually. 'Enough thinking!' You tell yourself as you sit on Piper's legs, spread eagle, letting your pussy gently rub over her legs.
The front door opens and you hear some clattering. Piper goes to get up but you push her back onto the bed. You know who it is. Roughly you fondle your sisters breasts and out of the crner of your eye you can see Paige standing in the door way.
"What the hell?" Paige asks and goes to turn but, the demon who had appeared earlier stands behind her and hurls another lust ball at Paige.
She drops her purse and rips open her blouse letting the tiny buttons pop one by one. Soon she is completely naked and standing right behind you. You lean down a give a firey toung filled kiss to your older sister as Paige's hand slips between you and Piper and feels your now, rock hard breasts.
