"As I see you in this situation, the sun is coming up, your parents are still asleep, I can spell them to remain asleep for another four hours while then Arron and you, have a brotherly equine frolic," the Genie said, as boldly baiting Brendan to go fuck a horny jennet mule.
"Hee-hee-haw...," Brendan brayed quite loud his reply.
"Really," replied the Genie as then Arron offered her thoughts, meager that she could think of, as stood winking her black lipped vulva, trying in her equine marish style of beckoning.
"Hee-hee, hee-haw...," as again Brendan seemed insulted at the idea of him breeding with his brother turned jennet mule.
"Okay, okay, I hear your gripe about not wanting to breed, mate with Arron, maybe a mare with a much bigger vulva is your preferred mate!" Genie asked, as thought to send Brendan down the country road to the Willis farm, where there they bred Percheron and Shire horses.
As Brendan was then giving the offer some thought, Arron broke her rein-rope and backed her big mule rump to within two feet from one undecided male mule. "HEE-haw," Arron bellowed as thrust her diaphragm, causing an ejection of her vaginal juices. The brownish colored vaginal juices then spewed, splattered at Brendan, coating his muzzle up to just below his big eyes.
The wet splat stunned Brendan and his first thought was to wipe clean his muzzle. As then Brendan realized he had no hands to wipe, he made use of his tongue and did a big licking of, as about his lips and nostrils.
Some of what Arron spewed forth entered the broad nostrils of Brendan, effectively causing him to do a flehmen reaction, he sucking deep into his nasal region the rank scent of a female equine in estrus. The flehmen reaction did the trick of arousing Brendan the male mule to gain a stout erection. As he brayed ever loader, Brendan turned and faced the rump of Arron. Being mostly equine, Brendan then slurped his broad tongue across the lusty vulva lips that Arron was winking.
Wagging his head with some hope to deplete the rank scent, Brendan leaped up as over the round furred rump of his brother turned jennet mule. As counted aloud by the Genie, it took Brendan three jambs to get his mule cock to touch, press, pushing inside, as traveling along the vaginal winking walls to where his blunt cock-head bumped at the cervix to a sterile womb. Sensual thrusting began and Brendan felt the brutal sensations that sparked a raw driving lust for him mating with a female equine.
"Go for him there Arron, let you stud give you as much a thrill as your lusty genitalia allows. Oh just relish the sexual weight of his cock, the smooth thrusts, and that bell-trumpet flared end of his ccock as it rubs along your ribbed muscular vaginal walls, the thrill is now so enjoy!" Genie placated Arron to act as if he/she were born to being as a female equine animal.
"Thrust there Brendan, dominate that horny jennet mule, feel how deep your cock has sunk inside her hot body. Rock your pelvis, thrust, thrust hard, get as much the thrill as you can muster, screw Arron good, screw him as you always wanted to, as if you both were gay, now the two of you make your lust as something natural. Go for the gusto Brendan, as hee-haw now but once to request as remain permanently to stay a male mule, live then 210 years of an equine style sexlife. Bray, bray, let me hear you bray!"
