Only if I beg her.

"Mmmm, I been waiting months to have you begging like this Domino." Momo sniggers in my ear.

Considering I have only known the little Helcion less than an hour it is clear she is deep into her own fantasy of topping her statuesque Captain. Who I guess goes by the name of Domino. I don't bother with correcting Momo, neither her or the Captain had bothered addressing me by my real name and Sweetcheeks or Sweety seemed to have become my pet name. In fact going forward the fewer people that learnt I was really specialist second grade Melvin Futterman inside this body the better. Right now I had other things to think about than what name I would be using.

Momo's finger was tickling the cleft of my labia, sending delicious thrills through my body despite the uncomfortable posture I was restrained in by the magcuffs and collar clamped to the deckplates. I could move only to squirm from the new and bizarre sensation of having a frantically vibrating fingertip stroking my pussylips. I was getting wetter by the moment, that I could feel, and the tight cleft I had only glimpsed felt like it was swollen and gradually loosening. Momo's finger traced up and down that cleft, deliberately coaxing the outer lips to engorge and gape for her amusement. I moaned as her teasing made the inner heat rise and the need for that hot wet part of me to be sated.

"Ohhh, look at you opening and dribbling for me." Momo giggled childishly as she teased my pussy into lewd arousal. "Not so high and mighty are you now Captain? Just another wet slutty pussy for Momo to play with."

The medic's fingertip explored deeper as my cunt relaxed and lips gaped opened. The flesh here was softer and more sensitive and my moaning increased. I knew Zetan's tended to increase a ****'s sexual libido with their nanobots, making them quicker to arouse and more easily brought to orgasm. It was certain I had been altered in just such a fashion when I had been transformed into this hypersexualised form. Another way of maintaining control, having slaves that craved being touched and fucked. I could see for myself how effective it was. I hated being used like this but at the same time wanted Momo to be done with her teasing and plunge her finger inside me and let me have my first orgasm.

"How's it feel here Dom?" Momo asked, and her finger slid up my damp crease and suddenly the pleasure her buzzing finger made me feel went off the scale.

Oh grief, that must be my clitoris! The pleasure was so intense my whole body trembled as I felt her vibrating fingertip stroke over a swollen nub of flesh. I gasped loudly and hoarsely, unable to remain silent while being subjected to such intense stimulation. I panted and groaned, shaking like a leaf and thought that any moment my first female orgasm would come. Momo though had other ideas, she obviously knew the effect she was having and pulled her fingertip away after just a few seconds of sending me wild with desire. I panted hard, my breaths ragged and rapid as the stimulation was snatched away.

"Ohhh please Momo." I moaned, **** for the pink haired Helcion to touch me there again and let me climax.

"Fuck it's good for you to be the one begging for a change." Momo said with satisfaction. "I wanna hear more. Beg for me to finger your butthole Domino. If you do I'll make you come with my finger up your tight ass."

I bit my lip, unwilling to plead with her to **** my butthole. Instead she began teasing my pussylips again, every so often letting the wickedly fingertip graze across my swollen and sensitive clitoris. I remained resolute for several minutes as the Helcion continued to tease and deny me satisfaction. All the while she was whispering and mocking me to beg her to put that finger in my butthole. Not that I could remain quiet during this intense teasing, I moaned, groaned and whimpered in frustrated sexual heat as she brought me close to orgasm several times before pulling her finger away just as I was nearing climax.

"You fucking bitch." I sobbed loudly as her finger was removed once more leaving me shaking and ****. "Do it! Please Momo, finger my ass. Oh for pity's sake stick it up there, just let me come."
