The female stands there, her bowels full of recently dead man as she explains it:
"I could just let him out a little bit, until his bum is just hanging there outside. Then you could have him fully. I admit, he won't be alive to 'enjoy' it, but it should be fun for you. It could take a while though before he arrives though. Why don't you fuck me until then?"
The male rhino answered at once "That would be nice. Will it take long?"
The female answered "It might. He feels good pressed up inside me. Fuck me to get yourself fully aroused again, and it will help him move out."
With that, she positioned herself for mounting by her mate, and he obliged her.
It was a more relaxed mating this time and this did the trick. He got off her when she announced "He is just about to come out." She gave a panting grunt and out came his legs, knees and thighs. She exerted herself again, and his hips popped out, the anus gripping him again on his waist. The naked skin of the man was slippery from his resting place, not to mention his own semen, urine and waste. There were some faint bruises appearing on his legs, and his anal opening slowly leaked semen from his previous encounter with the male rhino.
The male moved forward, using his 20 inch tongue to work the opening he wanted entry to. The male rhino worked the tongue slowly around before plunging inside completely. He could taste the contents of the rectum, semen from his own penis filling with lust. He tongue fucked him at bit more, the tongue spreading his buttocks apart widely. The base of was so thick, 5 1/2 inches in fact, it was nearly the width of his erect penis.
He backed away, leaving the ravished anus quite widely dilated. With a practiced leap, he was again had his front legs up on the shoulders of his mate, leaving only a few inches between the end of his cock and the anus of the man his intended to fuck.
The massive organ hung between the legs of his mate and the man, arcing upwards in a gentle curve of pink and gray flesh. With a twist of his hips, the male rhino pulled the head of the penis back slightly and it came to rest against the opening he wanted. The male pulled himself forward, his front legs tight over the shoulders of his mate.
The coupling went forward in fits and starts, as the rhinoceros penis went in, As first, only the first bit with the tapered shaft went in, followed by the wider portion beneath. The man actually slipped back inside the female, such was the force of the penis inside him. "Hold him tighter. I want to get completely inside."
With that, he arced his back and pushed his hips forward, the rest of the 24 inch cock being forced inside. When his large testicles rested against the mans buttocks, the rhino again paused to get a better position. The thrusts were slow at first, taking nearly half a minute from start to end. As his orgasm neared, the thrusts were much less gentle, his entire penis inside the rectum and some distance inside that. He was breathing hard with the effort now, each thrust completely fill the cavity it was in. The orgasm was equally tremendous.
His semen poured out of him, at first in waves, then in an actual stream like a firehose. He continued to pump the anus, but with each thrust he could feel less contact, as the rectum was filled with semen.
