The most Punk solution.

"I do want to get fucked," Sasha says, giving Ellen a quick kiss.

You smile and move in closer.

"...but I want something a little bit different. Stay there."

Sasha gives Amy a quick kiss too and then sits up.
She turns away from you and gets into doggy style position.

Ellen rubs her back, while Amy finds a tit.

"Fuck me....in the ass."
The trio all gasp in surprise.
"A girl has needs. I had a kinky Stepmom who taught me that the safest sex is anal.
Trust me, I can take you just fine," Sasha says.

You didn't expect to break that taboo today.
Amy didn't know that Sasha was that dirty.
Ellen only heard about anal in dirty Movies.

Sasha reaches back and rubs her pussy, getting her hand wet and presenting it to you.

"Put some of this on the hole and I'm good to go."
You nod and rub her juices onto your hand.
You rub and finger her asshole for a minute.

"Fuck me now."

You line up your cock with her asshole and get ready to start.
Ellen and Amy flank her on the bed.
