You take Alaina's ass.

"I've already had that pussy," you say, "So I know where I want to put this."
"Fair enough," Marlena says, "I think my toy might be too big for it anyhow."
"I'm so glad that we agree," Alaina replies, "Now take me!"

You both pull out of the girls' pussies and gesture for them to move out of the way. Alicia and Mary do just that.

The black girl goes over and starts to make out with the brunette in front of her before their tongue session turns into a bit of jockeying for position. Marlena ends up on her back on the bed with Alaina on top.

The duo help guide the strap-on into the latter's pussy, her enjoying the sensation of being filled up by a new 'dick.' They continue to make out while you get into position.

With Alaina mounted with her legs on the sides of her friend's body and Marlena's legs spread a bit, you find your opening. You climb on the bed behind the pair & aim yourself at a once-forbidden hole.

Seeing that both of you are lubed up, you slowly guide your cock into the girl's ass. It is tight, but she tries to give you entry as best she can. Beneath her, the black girl plays with her tits to help ease the entry process.

You eventually manage to enter her fully as the naked blonde and redhead look on.

"Are you ready," you ask, reaching forward and rubbing her back.
"I am. Thank you," Alaina says, "Now fuck me- both of you."

You both nod and begin to slowly, but steadily fuck the girl in both holes at once. This has to be her first DP, although she did suggest it, so who knows?

Grabbing her hips for leverage, you manage to start to really fuck her ass. Below her, Marlena grabs her thighs and pumps her hips to fuck her too.

Next to the bed, Alicia and Mary have locked arms and are rubbing each other's pussies frantically while watching the 3 of you.
