Slowly Lily came down from her high and caught her breath. I started to climb up as well, but Lily pushed me back. "Wait there."

She grabbed Monica with surprising strength and threw her over her lap. Monica let out a shriek but didn't try to escape. Her skirt was pulled up to expose her full behind. "No panties, a butt plug in your ass, and your pussy is dripping. Just like you said..." A hard slap landed on her ass, eliciting another shriek. "This is what you get slut. You're supposed to blow the customers, not seduce them." A second spank followed on her other cheek. "Guess we'll have to discipline you, you might lose your job if you keep doing this.

She kept spanking Monica's beautiful ass. Sadly I didn't have the best view, but I had to imagine it was starting to turn pretty red by now. I didn't expect the normally soft and cute-looking Lily to be able to take charge like that. Monica wiggled in place but didn't make any attempts to get up. In fact, she started letting out little pleasured moans every time Lily's hand came down.

"Louder slut, let him hear how much you like it." Lily looked down at me and continued: "She might look all confident in her waitress act, but I know better than anyone how much she enjoys being dominated." That pushed Monica over the edge and she let out a long whiny moan.

"That should do it." Lily pushed Monica back up, who carefully sat back down on her sore butt. "Sit straight and spread your legs skank. She looked at me again. "Start licking and don't stop until she is screaming."

My girlfriend telling me to make another girl scream is not something I'm gonna question. I did glance up at Monica. If she was in pain, her face did not show it. She seemed embarrassed when she caught me looking, but mostly she looked needy. Even more than when I left her on the edge before.

Lily nudged me with her foot and I refocused on my task. I scooted over to sit between Monica's knees and started licking again. I was happily growing more familiar with her pussy and likes. Monica was already breathing very heavily and was more than ready to finally reach her orgasm. Not wanting to tease her any longer I went straight for her sensitive button and got her moaning straight away.

Not long after she started getting louder, but then it seemed like the sound got muffled. I simply kept going determined to satisfy her. After only a minute she too was shaking above me and I pulled away.

A hand on my hand stopped me. "I didn't hear any screams. Keep going." Above me I saw Lily holding a hand tight over Monica's mouth, stopping any noises coming out. Of course, I went along with whatever Lily was planning, so I went back to Monica's pussy. Monica for her part started squirming a lot more, probably still sensitive from the intense orgasm she just had. But she didn't have the strength to escape both me and Lily.

This time I decided to go all out and finger her as well. My first finger went in easily and I added another right away. I now knew where to look, so it wasn't long before I found Monica's G-spot too. I started fingering her faster while still licking and sucking her clit and it wasn't long before she started shaking again. Lily took her hand off Monica's mouth and I heard the loudest moans yet.
