You join in

The sight of the ripe young teen plunging away on your roommate's cock has you immensely aroused. Smiling at the scene on your bed, and pleased that Brian is now just as complicit as you, you strip your clothes off, tossing them onto a chair.

Your cock is rock hard and you feel like a stallion as you climb onto the bed, your cock level with Valerie's head. You're about to pull her towards you but it's unnecessary. As her lust glazed eyes notice you she reaches out and grabs your shaft with one hand, her soft warm mouth engulfing you as she moans happily. Her head bobs as she rides Brian's bucking hips and the lewd slurping sounds she makes as she sucks you are incredibly erotic.

"Fuck what a hot little bitch!" he groans as she writhes on his meat. "This was a great fucking idea Mason!"

"Yeah, this one loves to please her Daddies, don't you Valerie?"

"Yes Daddy," she moans, taking her mouth off your cock to answer. "I love both my daddies! I love being a good girl for them!" She sucks the tip of your cock back her mouth, humming happily around the sensitive flesh.

You hold her hair and thrust deeper into the writhing girl, loving the feeling of dominance you get from using her willing body. You give a silent thanks to Donna and Lorri for their advice about punishing Valerie for her nastiness, but you doubt they had this outcome in mind. Or did they? Maybe this was just what they expected, you think to yourself.

With that thought you decide to put the next part of your plan in action.
