Getting used to a new shape

Obviously today's fantasy was a little bit furry and Steve looked down at his busty cowgirl sister tugging on her tail as his thick knotted cock plugged her rear. He groaned as he felt his face change his mouth and nose forming into a long canine's Snout.

Well were stuck together you slutty cow," he remarked squeezing her massive milkers as he nibbled on her neck playfully kissing her in the forbidden formation he felt something different a tingle below the waist and grinned with satisfaction as he felt something else In between his legs.

A second thick knotted member was going in at just the perfect angle to pierce between his sister's legs and moments later she was impaled on both of them. He thrust in and out squeezing her nipples nibbling on her neck as they continued to rut together. he definitely didn't object to this in fact the sudden doubling of the pleasure between his legs only made the taboo sensation even more intense.

He nibbled and licked at his sinful sisters neck as he continued to lift her up her heavyset body sliding down onto his twin shaft with delicious rapidity. He couldn't wait to fill her up completely To completely seed her with his offspring. It had to be one of her fantasies not that he minded. Standing 7 foot tall with An impressive amount of muscle covered by a thin black and silver coat of fur that made every sensation magnified he continued to ram into her until eventually his softball sized testicles twitched.

Another delightful dense dose of sibling semen spewed from his thick twin tree trunks liberally seeding his sisters womb and her rectal cavity before finally pulling back.

And still he kept going, covering her busty body in streams of sticky semen taking in from the front her own changes not quite as dramatic as his. She still had her human face which suited him just fine as he coated her inside and out before finally allowing them both to clean up.

She had massive breasts easily a G cup and along tufted tail that matched the cow horns and ears. She moved with pleasure as Steve molested her body thoroughly enjoying himself even in the process of cleaning up debating whether or not he was going to use his altered biology to really make her moo.

He could easily get hard again but decided to finally let her rest for a moment after all he had a lot of things to do today and potentially have some fun at work.

Giving his perverted sister one more kiss Steve went to work, leaving her milky mooing mess.
