You tell the truth.

“Well, she’s not exactly lying. I’m obviously fucking her tight little ass, but it was her idea. She asked me to do it.”

Marcy lies again, but can’t stop giggling, “Did not. I was sleeping and woke up with a dick in my ass.”

“Liar.” A very childish back and forth continues, which is especially odd as your dick is still in her ass, and now harder than ever.

Vanessa silences both of you, “Enough. You both know I’m not stupid, right?”

Both of you in unison answer, “Yes ma’am”. She puts her finger over her mouth, as if thinking about her decision, “Well, clearly we have a she said, she said dilemma, and while I find Marcy’s giggling to be evidence of a lie, I can’t be sure. So what do you two think I should do about this matter?”

Marcy speaks first, “You should probably just fuck both of us.”

You think it over, a grin grows on your face, “I was bad. I should get fucked... But Marcy was a little bitch and a liar, I think you should just make her watch.”

Vanessa responds to your statement instantly, her cock starts rising. “Oh Alex. I didn’t see that coming. You are wicked. I’ll get my ropes.”

“Wait. What. This isn’t funny.” Marcy protests as Vanessa proceeds to tie her up like a Christmas gift, but is eventually silenced by a bright red ball gag styled like a twenty sided die. She is at the head of the bed positioned to see everything.

Finished she turns to you. She tosses you a bottle of lube from her desk. “Fill your ass and bend over.”

You do as instructed, quivering, you can’t believe what you are about to do, again. She fingers your ass till she is satisfied you are ready, then grabs your hips and slides the head in. You gasp and hold your breath.

“Breathe, sweetie.” You gulp air, she slides forward. Her hips soon press against your ass. “I have never met someone that can take my cock so easily. I think the gods themselves brought us together.”

“Oh fuck, it’s just so good. Why does it feel so good?” You ask panting as she slowly increases speed till she is slapping against you with every thrust.

“Oh, your ass is fucking amazing.” She howls. Then finally she says, “Let’s just stare at Marcy as we cum.”

“I’ve been cumming for a while now, but okay.” Your cock is just flowing, you stare at Marcy. She is fuming.

Vanessa pumps a few more times, slowing, then slams it in to the hilt and fills you with cum. She pulls out, “Should we let her suck the cum from your ass?”

You answer.

Yes.

No.

If she wants.

Maybe we should fuck her.
