Healthy diet

"A fresh meal of semen should help you feel much better, Lily" agreed the Grey doctor. Then he turned to look at you and added, "You may proceed with that in a few moments." Next, he made a motion with his hand a large probe began descending from the ceiling. "Lily is due for her next checkup. We can proceed with both simultaneously."

By now, Lily's demeanor had completely changed. Just a few minutes ago, she'd been sullen and glum, resigned to the belief that she was about to die. The news that she didn't have the Withering had brightened her spirits, but now upon realizing that she was about to be directly fed a load of your cum while also being probed, she was overcome with joy. "Lily is so happy!"

As the probe descended toward her from the ceiling, you were shocked at its size. Of all the probes you'd seen so far, this was perhaps the largest one yet. The shaft must have been at least 41 cm (16 in) in length, and the diameter was at least 6.5 cm (2.56 in) wide. "It's huge!" you exclaimed.

As it reached the table, the doctor grasped it and aligned it horizontally directly toward Lily's crotch, and then pressed it against her anus. Almost instinctively, Lily seemed to loosen her sphincter, and the probe began to enter her rectum. Steadily it continued going deeper and deeper while Lily periodically shifted her hips to allow it to slide in more easily. "As Cunis get older, it requires the use of larger probes to get accurate readings," explained the doctor. "This is the standard size primary probe for her age. There are even larger probes for older Cunis." By now it was already half-way inserted, and you doubted it could go much further, yet it continued going even deeper. After the entire length of the shaft disappeared and only the connecting hose was visible, it continued sliding inward for a few more seconds until it finally stopped. Lily squirmed a bit, but she clearly enjoyed having this girth and depth of penetration.

Next, the doctor made a new motion and parts of the table shifted near Lily's head. He looked at you and said, "You may begin." As you moved toward the end of the table, you realized there was now a perfectly shaped area for you to stand against it. There was also a depression below Lily's head and neck, allowing her to comfortably tilt her head back to face you. She proceeded to do so and opened her mouth, much like a baby bird waiting for its feeding. After having watched the probe enter Lily, your dick was fully erect, and you began to slide your thick meat stick into Lily's waiting mouth.

It felt wonderful as you slid your shaft ever deeper. The head easily slid past her tonsils and down into her throat. Soon you had the hole length inserted and your balls pressed against her nose. She had taken most of your length that day in the hallway, but she'd never gotten it all the way in like this. Plus, your cock had grown slightly since then due to the Gargo regeneration somehow getting briefly reactivated. You were impressed at how easily Lily had managed to deep throat it this far without much of a warmup. Did all the orifices of Cunis become easier to penetrate as they grew older?

The building pressure in your abdomen had already become very uncomfortable, and Lily needed to be fed as soon as possible. Without delay, you began thrusting in and out vigorously. As you looked down, you could see the outline of your cock sliding in and out of Lily's throat. It was a huge turn-on seeing how deeply she was taking it. With each thrust, your balls made a steady slapping against her nose and cheeks.

Lily seemed to love getting double penetrated by the huge probe and your hefty dick, and she began moaning in delight. The special muscles in her throat began massaging your cock, desperately coaxing it to unload your cum. Of all the Cunis you'd throat-fucked so far, her technique was quite possibly the best. After less than a minute, you began to feel the surge building, and Lily clearly sensed it too. She started sucking more forcefully, and as her lips tightened around the base of your cock, she triggered the nerve bundle there, sending you over the edge.

You looked down and watched the outline in her throat as burst after burst of cum shot out of your cock sending ripples down into her esophagus as she hungrily swallowed each spurt. However, there was also a new sensation. It felt like your dick was getting even harder with each blast. At first it felt good, but then it started to hurt. Something was wrong. You still had over half a load of cum to unleash, but at the rate the pain was increasing you doubted you'd last that long. "Doc, it hurts!", you shouted. "What's happening?"
