"That's a secret." Said Alora with a smug grin.
Jeff sighed and pulled a strand of her long white hair out of her face and tucked it behind her large left cow ear.
"But don't you worry, as you'll see soon enough, Moo-Moo." Replied Alora with a giddy smirk. Jeff couldn't understand why Alora was so happy, but figured she was just excited to see how Kara turned out. Jeff also didn't even question the nickname she was just called by Alora.
Alora then walked passed her and slid her index finger up the slit of Jeff's pussy. She shuttered at the feeling, and her tail began to lift out of the way automatically. Alora squatted behind her and buried her tongue deep into Jeff's folds and began eating her out.
Jeff softly moaned while her girlfriend ate her out. She lowered her front half down, setting her E-cup tits down onto the floor and moo'd loudly. Her dick-teats began to trickle nutmilk as wave after wave of pleasure overwhelmed her body. The two lost track of time and suddenly after a loud cough, they realized that Kara was leaning on the door frame watching them. Her large udder with a pair of dick-teats limply laying over it looked to be quite full between her legs, and her arms were folded beneath her new, large pair of double D's.
Her tail flicked behind her large rear and she was glaring daggers at the two of them. Alora smiled back at her though, and the pissed off expression on Kara's face melted into a happy little smile as she excitedly entered the room. Jeff watched how her sister took a few steps before joining next to her while also moving to stand on all fours too. Kara gave her sister a playful lick with her long cow tongue, which Jeff returned to her with her equally as long, but instead forked tip tongue.
Alora knelt down between her two girlfriend's gorgeous asses and slid a fist into their almost identical pussies. Her arms sank further and further into either cowgirl until she was nearly shoulder deep. Both sisters were mooing loudly from this, and milk was streaming out of their teats and their nipples, though nutmilk was flowing out of their udders while breastmilk came from their nipples.
Alora may have taken advantage of Jeff's generosity of showing her her amazing device by making her upper half equally as feminine as her lower half, and making her become into her second girlfriend. But she didn't care. Jeff certainly seemed quite pleased with herself as she pushed her pussy back against Alora's left arm. Jeff's new, snow white hair and Kara's usual jet black hair made for an interesting combo too. And while she was still only 18, Alora had made Jeff appear more closer to a mid 20 year old woman, practically turning her into the white haired, bustier twin of Kara.
In terms of raw sex appeal, Jeff was ahead of Kara by a nearly insurmountable margin as Alora had made Jeff a lot more interested in having sex, but she also kept Kara's more mature personality to give her her own kind of charm that Jeff couldn't hope to match. Both sisters were fantasticly lewd and everything Alora could hope for in her relationship partners.
Alora also couldn't get enough of Jeff's nutmilk. While she didn't dislike their breastmilk, Jeff's nutmilk in particular tasted the best. Though not by much as Kara's own nutmilk was nearly just as good. "Hehe, you like feeling my fist I side of you, don't you Moo-Moo?" Laughed Alora as Jeff continued to grind her arm around her insides. Jeff moo'd in agreement which Kara took note of. She jealously also began moving her hips around, but unlike her sister, she didn't like it as rough, so she stopped after only a few seconds. Alora pulled her fist out of Kara's pussy slowly and lowered her face down to switch tactics and began eating Kara out instead.
Kara moo'd louder than ever and even Jeff was feeling jealous now. So she began fully fucking Alora's arm as if it were a nice large bull cock and she were in heat wanting some calves. The movement of her body caused her hair to cover her face again. Jeff tried to blow it away, but ended up making it worse and had to do it by hand after freeing a small bit of it from her nose ring.
It was then that the three girls heard the front door to the house open up and the sister's Mom walk in. Thankfully they were not in direct line of sight and in a different room so they had a few seconds to stop fucking and separate before their secret lesbian threesome romance was discovered.
