Is it okay to get off in front of a voyeuristic enemy? (MC x F)

"Hey, wouldn't it be interesting if you were the one in the middle, and I'm below you?"

"Huh?" I squinted, checking the drawing.

She started jerking me off while whispering in my ear. "Yes, imagine one of our teammates fucking you from behind while you fuck me. Would you like that, T.?"

My mind quickly superimposed Steve's face over the third participant.

"B-but w-we're trying to find what you would like…"

"I'd like this if it's exactly how I described it. Now, don't try to hide it... You imagined one of the guys just now, didn't you?"

"I…"

"Is Charles the one?" she asked, and Charlie's face got in my head. I could even imagine what he'd say: 'You have such a fine ass, Taylor, you're so tight! I knew you were special from the first moment I saw you!'

Oh…

"You're getting wet!" Grace giggled while continuing her hand motion. Or maybe you were thinking of Dan? He might be lanky, but he's kind of cute, isn't he?"

Now Dan was the one thrusting his hips against me, although not with the same intensity as my Imaginary Charlie. Dan's grunts were enticing and full of energy: 'Taylor, you're so incredible! I could keep going for hours, non-stop! You wouldn't mind, would you?'

I was panting, leaning over the table, with Grace furiously moving her hand. "What about Steve? You have been peeking at him since this quest started."

"W-what?! N-no, I haven't!"

"Gotcha! You know what? I might ask him if he would like to join us for a threesome! Would you like that?"

Steve's face returned to the page, and the entire scene got vividly animated in my head. Grace was below me, getting penetrated by me every time Steve pushed his gorgeous, huge cock against my tight ass.

Imaginary Steve: 'I've waited so long for this, Taylor. You won't escape from me ever again. Did you hear me? Because you're mine.'

Grace would join him saying: 'Don't forget you're mine too, T.! You'll be our little sex doll until we get out of this shitty spaceship!'

"M-Miss G-Grace!" I cried, eyes shut.

"Yeah, what is it?"

"I'm about to…"

"Yes, do it over the book! Come on, release it all."

"Do not mistreat the books," a third voice said.

My heart skipped a beat. I turned to our right, finding a gentleman sitting with his legs crossed and his head resting on his right hand. His whole body pointed in our direction, like casually enjoying the show.

"What?" I muttered.

"Do not ruin the books," he repeated in a jovial tone.

"Who the hell…?"

"He's been watching us for a while now," Grace said, making me jolt.

"And why didn't you tell me?!"

"Hey, focus, don't lose your erection yet!" She jerked me off again, making me moan.

"But he's…"

"One of the mansion's bosses, yes," Grace finished the sentence. I glanced at him, admiring his black-and-white striped business suit and his mask, imitating a happy, winking face.

"He's not doing anything…"

"I know," Grace said. "Ignore him. Or what, you can't cum now because he's looking?"

"But he said to not ruin the book..."

"To hell with him! Come on, do it."

"I c-can't."

"Goddamit Taylor, you're becoming flaccid! Fuck. I'll freaking help you then." She got in front of me and kneeled. "Would this help?" She opened her mouth and stuck out her tongue.

"I thought you didn't like the taste of…"

"I don't like it, idiot. What I want you to do is to use my mouth, like that one illustration you liked? But on the condition that you cum over the book."

Use? Did she say use?

I glanced at the fake librarian.

"He'll attack us."

"I told you I didn't like this position, didn't I? So don't you find it alluring? Forcing me to do it?"

All of this was a big, twisted game for her. My dick got hard again, despite the NPC, or monster, or whatever that humanoid thing was, watching us. I reluctantly got inside her mouth and… oh… I had forgotten how warm and moist and awesome it felt.

She closed her lips against me, but did nothing more. She just stared at me, daring me to continue.

I remember the second illustration, the one that rewarded me with a punishment… And I moved my hip forward once. The sensation… It was impossible for me to not try it again. I did it three more times… Oh, I had never felt something so glorious before!

"Is it okay if I do it faster, Miss Grace?" I asked, and she frowned, grabbing my balls. "W-why? What did I do wrong?" I muttered. Maybe she got angry because I asked for her permission when she had already given me a free pass? "Oh, Grace…" I said, grabbing the back of her head. This woman, who liked to be in control at all times, was letting me fuck her mouth just to get what she wanted? "You're truly the devil, did you know that?"

I stopped my hip movements so she could reply. "I know, and you like it. Don't forget what I told you. Don't cum in my mouth, you heard me? If you do it, I'll burn your freaking--"

I silenced her bossy voice by thrusting my dick inside again. Others had done this to me before, and now I knew why! It was freaking awesome! Although they made me cough and gag, I suppose that my Lady D. was not big enough to choke her. Anyway, being able to thrust all of its length inside her mouth was more than pleasurable.

"I'm using Miss Grace's loving mouth," I whispered while looking her in the eyes, and I could see a gleam in her gaze. Was she enjoying it, too?

I glanced at the librarian, stubbornly looking at the book. Or was he really enjoying our show? It didn't matter; I continued moving my hips back and forth, closing my fists against her hair… To stimulate me, she caressed my balls, pleasingly this time. But… Why was I missing the mistreatment?

"Can you… scratch me?" I asked, and she made a guttural sound, as if she didn't understand my request. "Use your nails and scratch my balls!"

She did, and although the sensation was unfamiliar at the beginning, with the passing time it multiplied the pleasure, accelerating the imminent release…

I… didn't expect that!

"I'm about to--!"

"Do it!" Grace ordered, rushing to get her face out of the way.

I aimed towards the table, and thick bursts of liquid joy fell over the spread pages. "I'm so sorry, librarian!" I cried, not actually feeling sorry in the slightest.

The gentleman rose violently, making his chair fall. "YOU WILL PAY FOR THIS!"

"Shit!" I shouted, stepping back to equip my gear as fast as I could, as Grace finished casting: "Flame Trap!"
