They both do!

"Me," Alicia says, "I used the strap-on without asking. I'm very naughty!"
"No, me," Mary says, "I asked her to use it and got fucked by it."
"I'm naughty!"
"I am!"
"No, pick me, dam-MMMPH!"

Alicia is interrupted by Alaina shoving her face right into her pussy. Apparently she decided for them.

You and Marlena manage to get all of the way inside of her roommate's pussies and start to fuck them. The redhead sure is tight!

"Tell me you like my dick," you command.
"I love your dick," the redhead cries.

You reach down for her hands and see that they are still near each other, the girl acting like her wrists are bound together. She has hooked her thumbs to make this easier.

"You don't fuck as good as I do, right," Marlena asks aggressively.
"No, you fuck better than everyone," the blonde cries out.
"Is that a challenge," you ask, giving your girl's ass a smack.
"Maybe. We can let Alaina decide later."

Speaking of her, she has moved to Mary and is pressing the girl's face into her ass. The redhead happily tongues the brunette's asshole, showing no signs of trepidation.

After a few more minutes, both Alicia and Mary have cum twice and Alaina is ready to go.

"Time for the Main Event," she says, "Who takes what hole now?"
