Take her from behind

You can tell a true slut from the way they grin. Gilli had such a grin. Jason's new sister slinked over towards the large TV. She ducked her head down so she could kiss the moving image, kissing her father as his cock pumped into her new mother.

"Take me from behind," she tempted her brother, spreading her legs wide apart. Gilli slid her body up the flat TV screen and wraped her hands over the top of the unit. Her breasts were pushed against the monitor as she braced herself in preparation for her brother's advance. "Fuck my cunt," she murmured in lust, "Or take my backside... just make me your whore." Gilli churned against the TV screen, wriggling her naked body at her brother.

I watched as Jason moved over the floor towards her, holding his cock in his right hand. I had spotted the not-so-hidden camera in this room and I knew it had a fanastic view of the action. It had a microphone attachment too. I suspected Jason liked to record his own adventures with the girls he brought down here.

I would want to fuck Gilli's pert backside. I would want her to **** her wet snatch against the TV footage of her father with her mother. It would be a good video to show her mother while I fucked her.

I had another decision to make. I could let Jason fuck his sister how ever he wanted. I could encourage Jason to go for Gilli's backside. I was sorely tempted to get involved myself.
