The female was captured by Pluvian just recently. She put up quite a fight, but the plover was very good at dealing with large creatures, it didn't take long until she was lying fully immobilized in the special restraint bed Pluvian had ready for her.
Seeing that the restraints were working perfectly, Pluvian looked around on his table full of all sorts of toys. The dolphin followed his every movement closely, she had no idea what he was up to and what all that equipment was for.
The plover finally grabbed the bottle of lube and went over to the dolphin's rear, causing her to pull against her restraints once again. Pluvian stroked the dolphin's belly first, his touch making her tense up, but he kept going until she stopped squirming.
He then started to move lower and slid his toes along the length of her slit, provoking a bit of struggling again, but continuing all the way down to the very end, over the little fold of skin, and ending up at her anus, to which she reacted with a quick strong jerk.
"Oh, this is going to be fun." thought Pluvian.
He took the bottle of lube and applied a large amount of it on two of his toes, coated them nicely, then poured some extra lube on his toetips.
He touched the dolphin's anus and spread the extra lubricant all over it, gently rubbing the opening, and trying to push some lube deeper too. The dolphin clenched her anal muscles instantly and started struggling again, much to Pluvian's delight. She also let out a few angry whistles, but all it did was encourage her captor even more. Pluvian liked the dolphin's strong, defiant reaction, and figured this was the first time somebody touched her there.
He was right, she's never had her anus stimulated before, this was a completely new sensation for her. She couldn't help but feel a bit of excitement from all the stimulation, which started to show on her skin as well, turning her lower belly slightly pink.
Pluvian poured some more lubricant on her anus and started rubbing and pushing his toes deeper, feeling the final resistance of her internal anal sphincter. He pushed against it, and due to all the lube, he managed to pass through it quite easily, ending up with his toes deep inside the dolphin's rectum. The moment her internal sphincter was penetrated, the dolphin jerked hard and struggled violently against the restraints to no avail. This caused Pluvian to smile and start wiggling his toes a bit inside. He took great pleasure in knowing that she was completely at his mercy.
After a bit of exploring, Pluvian pulled out his toes, and refreshed the lube coating. He slipped them in again, rubbed them around a bit, then pulled out, only to shove them back in immediately. The dolphin was going crazy, but there was nothing she could do, she was completely defenseless against her captor.
Pluvian then decided to take the dolphin's rectal temperature. He grabbed the glass thermometer, applied some lube to it, then pressed the tip against her anus. He slowly pushed it inside, and after the wide part was through her sphincter, he slid it in until around 2/3 of the thermometer disappeared deep inside the dolphin's rectum. He waited a few minutes to get the reading, meanwhile enjoying the view of her anus clenching and pulsating around the thermometer. Once the time was up, he slowly pulled it out and read the thermometer.
