Anna slammed her cock inside David's ass. He was overrun from the incredible sensation, his ass on fire. She placed her hands on his butt to get a better grip as she continued pumping her cock inside his black butthole. David started to follow the rythm with is hips, his balls swinging freely with each thrust. He felt all the weight of his testicles like never before as the pressure for release started to build up.
"Anna...keep going... i'm about to... to... cuummm!!"
From the tip of his erect penis flowed a river of white cum, each contraction releasing a thick spurt of liquid. Anna was still inside him and as she slided out of his dilatated butt she saw the puddle of cum forming forming beneath him.
"Aww donkeyboy is making a mess" she joked as another spurt come out of him. She wrapped her lips around his dick to taste the sweet liquid. The taste was different and the the amount of it was incredible. She gulped again and again until with a last contraction the flow of cum stopped.
David was panting as his dick slowly softned. His balls were heavy and swollen.
"Ohh look, donkeyboy grow some balls!" she reached out with an hand to feel the heavy teasticles. The skin of his scrotum was thight and stretched around the still pulsating testicles. They were now the size of lemons and the skin had also changed to a much more darker tone compared to his light complexion.
David got up and looked at himself.
"They are really heavy... jenny, I have donkey balls! it is amazing" he started to move his hips to swing his balls around.
"I'm so happy for you dear, they are really beautiful."
She embraced him and reached again for his balls.
"I could play with them all day"
"What are we going to do tomorrow?" he asked.
"Whatever we want" she replied placing her head on his chest.
Next morning they both woke up when the sun was high. David balls were even larger than the previous night and his skin around them changed to a complete black. Anna was looking at herself in the mirror, her ears had elongated more during the night and now passed the top of her head.
Still naked David opened the door of their apartment, a big box was outside.
"Good, they found some"
"Found what,dear?"
"A little present for you Anna". said him handing her the content of the box.
She looked inside and saw a light blue long dress and a hat to complement it.
" No more discomfort from panties and jeans" said him while she was dressing.
" Thank you, it is really comfy but... what about you? with those you clearly can't fit inside your old trousers." replied her pointing at his dangling balls.
"Don't worry for me dear, i have asked also for this"said David showing her a pair of baggy shorts. The bulge on the front of his shorts was pretty obvious.
"So, what do you want to do today?" he asked her.
"What about a trip on the lake? we could relax on the beach and swim "
"Ok it will be fun, lets go."
The sand of the shore was warm under their feet. A light breeze gently shook Anna's dress while David planted a beach umbrella in the soft sand.
Near them, in the water, a group of girls and boys was playing with a ball. They were some years youger, maybe in their early twenties, some of them were naked while others still had swimsuites on. A naked girl, whom was sporting long donkey ears with brown fur, tossed the ball high, another one, whom was still whearing a red bikini, jumped out of the water to hit the ball showing a long grey tail just above her butt. The ball hit one of the boys hard on his face making him fall backward into the water. All the group laughed with a mix of brays and laughs.
Anna removed her dress revealing her beautiful naked body. Her ears twitched at the sound of the mixed laughter then she laid on a pink beach towel to sun bath, showing her equine pussy as she bent over.
David undressed as well leaving his black heavy balls free to swing in the fresh air of the morning. He placed his towel under the shadow of the umbrella as he didn't like sunbathing as much as Anna.
David and Anna relaxed, peacefully lulled by the sound of wind and water.
SMACK!
The ball dipped in icy water abruptly woke David by hitting him on the back.
"HEY GUYS, DO YOU WANT TO PLAY?" one of the girls was shouting from the water inviting them to join the game.
" Anna do you want to play?"
"No, I don't want to get wet, I prefer to stay here."
"Come on, lazy jenny."David threw the ball back to the group and stood up, then he grabbed Anna and put her on his shoulders.
"NO! NO! NO! PLEASE! THE WATER IS COLD!"she tried to resist by kicking.
He raised her above his head with both hands and threw her into the cool waters of the lake jumping himself immediately after.
"YOU JACKASS!" Anna yelled at him as the group laughed. She wasn't really angry and in moments she got used to the cold water, only her nipples were hard.
"Hi guys, nice to meet you. I'm David and she is Anna" David introduced them.
"Hi, I'm Clara" said the girl in the red bikini "That's Mark, my boyfriend" pointing to a tall naked boy "Those are Joan and Carl" pointing to the naked girl and a short but heavy boy "And those are Paul and Rich" she said introducing the last two boys of the group.
"Nice to meet you all" said Anna.
Clara was a nice girl, a little taller and thinner than Anna, with very fair skin and red hair. Her tail was covered in reddish brown fur with a black tassel at the end.
You know how to play, right? In the fifth step you have to dunk and hit someone. If you miss, you lose a point, but if you hit, the target loses a point. We have five points, the first with zero is the loser.”
She raised her tail out of the water and with a jump threw the ball into the air. The ball flew high in the direction of Rich whom prepared to recive it. Rich was very hairy, he wasn't covered in real fur yet but his coat was already lighter on the front and darker on the back. His tail moved to the left side as the ball hit his arms.
“Coming your way, baby!” he said directing the ball towards Paul.
The shot was a bit off, so Paul jumped out of the water to hit the ball towards the group. Paul was a very fit guy, his whole body was covered with well defined muscles and he was completely shaved. His jump was incredibly long and while he was still in the air David noticed that his feet had already become hard hooves.
With a precise shot Paul sends the ball to Anna who with a quick pass threw the ball to Mark. Mark looked a lot like Carla; tall, thin, fair-skinned and with red hair. They could have been mistaken for brother and sister. His ears were long and hairy, and a line of dark hair ran down his neck and back.
“Nice pass!” he said. He flexed his legs and his dark balls dangled beneth him touching the waters of the lake. His pass was long but the ball flew straight to Joan. She was ready for a strong dunk to hit David. She had long donkey ears covered in grey fur and her pussy had clearly already changed, her hips were really large. When she smiled after her dunk she revealed two very large front teeth.
David dodged the shot.
“Ah! you missed me, you lose a point.”
“Next time you will not be that lucky” said Joan.
David retrived the ball and resumed the game passing the ball to Carl. He was shorter than David but despite some fat around his belly he looked really strong. His eyes were completly black and above his purle swim shorts was a short airless tail.
The game went on until with one last strike Anna eliminated Clara.
“Oh come on, not again! I lost two times already today”protested Clara.
The rest of group was laughing while she reached the sandy beach. David and Anna were confused. Once out of the water Clara dropped on all fours. She raised her tail.
"Here Anna, come and get your prize," she said, taking off her red bikini.
