Small male rabbits had to remain unmated. That was the rabbit way. Small buck rabbits did not become fathers. Not that any buck was a good father. Love them and leave them was the buck rabbit's motto. The leader might appreciate having a large group of rabbits but whether the kittens were his or not he didn't care.
The young buck rabbit twitched his nose in the gathering dark. He was very small and only just old enough to want to mate with a doe rabbit. He'd have little chance until he grew big enough to take on other bucks, if he ever grew that big. He had been the runt of the litter and probably his whole life would be mateless, always shoved aside by bigger rabbits.
He could smell a faint scent of a doe on heat. His instincts took over. He lolloped along towards the edge of the forest. There ahead of him it was almost completely dark but the scent was stronger. His nose twitched frantically as he searched for the source of the scent. A doe on heat this far from the warren might be receptive to anyone, even a buck as small as him. His excitement became unbearable as the scent grew stronger.
Then he saw the unmistakable sign of a rabbit. There in the gloom ahead of him was a raised white scut. The female must be waiting for him with her scut in the air to guide him. Caution took over for a few seconds as he remembered the harsh lessons given to him by the bigger bucks. He didn't want to be pounded to the ground again and again. He crept forward, his nose extended to search for the presence of another male. There was nothing but the arousing scent of the female.
The raised scut was very close quivering in the dark. Above it was a spreading bush. Beside it was a tree stump. Very slowly he edged forward until his nose was nearly touching the receptive hole below the scut. The scent was driving him beyond endurance. Was there another male in the bush or behind the stump? Even if he paid for it with his life he had to mount this female. His nose touched the entrance very carefully. The scent was bliss. This would be his first time. He pushed his nose harder against the female to tell her he was there and ready to serve her. She pushed back and his nose sank into her warm wet hole.
