Olivia uses the marker on you

"Now you're finally being honest," Olivia cooed. "And, I think I'll make sure you keep being honest."

Her telekinesis pulled your arms in front of you. Olivia took the marker to your right forearm, and wrote the word OBEDIENT, and then wrote on your left arm CANNOT TELL LIES. Her as she did this, her large hard cock, still wet from Stacy, pressed against your own much smaller one. When she finished writing, she moved your arms back down to your sides, but stayed close enough that your cocks were still touching.

"Stay still," she said, as she released you from her telekinesis. However, you still couldn't move, as the marker **** you to her commands. "Now you won't be keep any more secrets from me. So, Finn, do you like my cock?"

You stayed silent. You couldn't lie, but she hadn't said you needed to answer her questions, so you weren't being disobedient. You didn't want to let her know how much you liked feeling her cock on you. As long as you didn't speak, you wouldn't have to tell the truth.

"You will answer when I ask you a question," Olivia said. Her voice was now commanding and serious.

"Y...yes," you whispered with shame in your voice.

"I bet you might even want to know what it feels like to be fucked by my cock, don't you? And speak up this time. I barely heard you a moment ago."

"I want to feel your cock!" you shouted out.

"Doesn't honesty feel good? You don't need to answer that one. I already know the answer."

You looked over to Stacy on the bed. She was rubbing her clit, and hadn't taken her eyes off of Olivia's cock. She barely noticed you were there. Was it just the effects of the marker, or was Olivia just that good? Olivia's voice threw you from your thoughts.

"Here's an idea. I could just fuck you in the ass right now. Or, I could use this marker to turn you into a sexy, slutty girl like Stacy here. I'll let you pick. Which do you want, Finn?"
