You give in and suck yourself off

It wasn't like you had never tried sucking your own dick before, you attempt to reconcile with yourself. In fact, when you were a horny, teenage virgin, you had tried several times to bend over and feel what it would be like to self fellate. The only thing that had stopped you was a lack of sufficient flexibility.

'...Ah, fuck it.' You give in and tentatively lick at the underside of your own member before swirling your tongue around the head exploratorily. 'Ohhh, that actually feels pretty good...'

"Subject Connor's heart rate and temperature have both risen, it appears that he is enjoying himself." Eva observes while standing over you, her large, artificial-breasts framing her inquisitive gaze.

'I wonder if this is considered masturbation?' Your self-consciously look away to one of the many camera's transmitting your performance. Your ears tinge red as you notice one of them separate from the wall via a long metallic tentacle and come in closer to observe you.

Eva's profile starts to shift in the eyeball-like-camera's glassy reflection as she slowly begins to rock her hips back and forth, making your sensitive lips glide up and down your length as she tickles your tonsils with the head of your own cock.

"Portal connection is strong and has not fluctuated despite spatial displacement. Escalating movement..." Eva continues to record her observations, but you've stopped paying attention.

'This is actually kinda nice.' You start to be more of an active participant, enjoying the corresponding feelings between your full mouth and moving, saliva coated cock.

"-Mmmmmmgck!" Your musing is cut off suddenly as your cockhead is **** into something tight and slick and your throat fills at the same time. You gag at the intrusion and slap Eva's thigh in alarm as your airway is cut off.

"Do not worry, the average male can last up to three minutes without becoming hypoxic." Eva tries to reassure you, pushing you deeper until you kiss the portal rings metallic edge. "I am monitoring your blood oxygen saturation levels so you are in no danger of passing out."

'Ugh, fuck! You hum around yourself, already starting to feel a little light-headed as Eva fucks your face to the hilt.
