Firmly stuck

The Grey doctor looked up from a nearby screen and immediately made a motion with his fingers. In response, fan-shaped beams of rainbow-colored lights washed over you and Lily. "This is remarkable!" he exclaimed. "The Gargo tissue regeneration has somehow been reactivated again." With another hand motion, a pair of beams of bluish light and a wider cone of reddish light struck you in the lower abdomen, just above where Lily's chin was currently positioned. "This may feel a bit strange," he continued, "but I see no other choice." First, the reddish light glowed brightly, but you didn't notice any effect from it. Then the doctor made another motion that you recognized as 'increase' and the brightness of the blue beams intensified.

Strong abdominal cramps immediately followed that along with a new feeling that reminded you of taking the biggest and hardest piss of all time. Instantly you felt the next blast of semen explode from your dick deep into Lily's throat, but instead of it being a momentary surge, it continued and even grew stronger. For the moment, your cock was firing out a steady stream of cum at maximum ****, and the feeling was incredible. As it did, you looked down to see Lily's belly rapidly swelling from your flood of incoming semen. After several seconds, your over-sized semen glands were finally spent, and your most intense ejaculation of all time finally came to end. You waited for your giant shaft to begin to shrink, but oddly it didn't. You spend the next few seconds wiggling your pelvis to no avail.

"Um, doc? There might be a problem. It's not getting soft." you explained. "I think it's stuck in Lily's throat."

He motioned his hands again and the blue lights vanished, but the red cone of light was still covering your abdomen. "It was necessary to empty your semen glands as quickly as possible to help prevent further regeneration and to also suspend the rest of your sexual organ in its current state. One side effect of this suspension beam is that it also prevents your erection from shrinking, leaving you in the current predicament. However, there is no danger. Both of your readings are stable."

Hopefully, Lily wouldn't mind having your massive Gargo dick stuck in her throat for a while longer. If she was human, she would suffocate, but due to her Cuni physiology having a separate airway, she could breath normally. "Lily," you whispered. "Are you OK?" She couldn't speak, but she made a hand gesture that indicated she was alright, and she also rubbed her swollen belly proudly. Then you turned to the Grey doctor and asked, "How long do we need to wait, doc?"

"The external scanners are not detecting anything that could have caused this. We require a more accurate device to gather as much data as possible before you are separated." He turned his attention back to a nearby console and searched through several historical records before he finally found what he was searching for. "This should suffice," he announced and then began entering commands on the console. "I will prepare the probe."
