Despite having his airways blocked by the warm latex, Buddy could still breathe. His ability to breathe was due to his divine nature. The rat breathed because he could not do otherwise anyhow. He was what he was, an undying creature from above reality itself. His soul or spirit, whatever it was, was separate from himself. And yet he still suffered the encapsulation and humiliation that Sixus the latex rabbit imposed upon him.
Inside his mouth was a thick protuberance of latex in the fashion of a penis. It had gushed into his mouth, solidified, and expanded to keep Buddy's jaws as wide as they could comfortably be. The taste was simply that of latex. It moved very little, merely pushing and pulling in very slight thrusts.
The latex encapsulating his body very softly writhed about his fur. Buddy's own penis was particularly surrounded and lightly stroked. Indeed, Sixus was pleasuring him lightly. Occasionally, Buddy would cum. His semen would spray out into an empty space, and the sticky substance would be vacuumed away to another place. Buddy did not know where.
His anus was completely filled and stretched as wide as he could reasonably handle without too much pain. The phallic-shaped insertion had initially moved very slowly into his guts, causing the rat some distress. Sixus carefully monitored the rat's reactions to the internal movements. He never went too far, but he did go as far as he could before Buddy could stand no more. Here, the long latex penis stopped and simply began to lightly move in and out.
Buddy was being fucked in two holes and his penis was being stroked at the same time. Everything was slow and rhythmic. The patterns were constant. It was tight and intense, but it never breached being more than Buddy was comfortable with. For these reasons, the rat who was God began to relax. He lay there suspended in the body of his captor and was simply fucked for a time. He orgasmed whenever it drove him to do so, and the cycled continued.
And through all this, Sixus hummed a soothing tune. This tune further comforted the captured rat. Buddy occasionally fell asleep even while he was fucked. He even came as he slept. And when he would wake up, the fucking and pleasure continued.
This would go on for some time. No words were yet said. The two had become one for a time---Sixus who was once Ixus... and Buddy who was once Surly. Everything was dark. Everything was quiet.
