Barbie spent the next minute ingesting more cum than ever before, which was not really a big accomplishment given how she had only just lost her virginity. By the time the final wave oozed out of Hornier’s cock, both lovers were covered in a second thick layer of cum. Releasing the puppy’s cock, Barbie wiped the orgasmilk from her eyes and only just had time to see the tip of his manhood get swallowed up by his body.
By then, Barbie was hornier than ever before and desperate to escalate the first sexual encounter of her life. Luckily, one quick glance at her cum-covered sibling was enough to tell her Barby was not about to let her down. However, it also informed her the other birthday girl was just as horny as her, a fact that was soon made clear by the teen’s hand stroking her pussy through her cum-soaked panties.
“Oh my god!” gasped Barbie as this sight.
“Fuck!” was all Barby found to say as she yanked her hand from her crotch.
As shocked as she was by her sister’s actions, Barbie soon realized her reaction was way out of proportion. Of course, getting turned out at the sight of her sibling having sex with a dog was perverse, yet it was far less raunchy than actually having sex with a canine. Because of this, Barbie soon wiped the shocked expression from her face.
Having come to the same conclusion, Barby decided to voice her next dare.
“I dare you to have sex with him,” she said, nodding to the cum-covered puppy that stood between the two siblings.
Although Barbie was hornier than she ever membered being, she could not help but experience a moment of hesitation. A handjob was one thing, but actual intercourse was taking things to a whole new level of perversity. Yet, such a realization brought no fear whatsoever. In fact, the emotion that accompanied it was eagerness. Taking advantage of this, Barbie turned to her canine lover.
Fortunately, the puppy had spent that entire time ingesting as much hot orgasmilk as he could. Unfortunately, his cock had only just begun making its second appearance of the evening. Luckily, Barbie was all too happy to come to his aid. Using her hands, lips and tongue, she soon got her lover ready for the third and final round of their interspecies sex session. Within seconds, a rock-hard schlong stood perfectly erect between his hind legs.
Lying back down upon the cum-covered bed, Barbie spread her legs wide. Luckily, nothing more was required of her. Taking matters into his own hands, Hornier hurried over to his human lover’s crotch. Placing his front paws onto her stomach, he hopped forward until his manhood hung mere inches from the birthday girl’s soaking-wet pussy. Without a moment of hesitation, he jerked forward, forcing his prick past the teen’s lower lips.
“FUCK!” moaned Barbie in a mixture of arousal and surprise. The arousal came from the feel of that hot prick stretching her out like never before. The surprise came from the fact that every last inch of her lover’s spear was soon forced into her.
“Wow!” she gasped when she realized she now had a total of six inches of canine cock stuffed into her pussy. However, that was all she had time to realize before her lover started jerking back and forth with great verve. Within seconds, he was pounding her so fast and hard the teen only barely managed to keep her moans low enough to keep Candy from hearing them.
Meanwhile, Barby remained nearby, her eyes glued to the interspecies couple. By then, she had taken the time to remove her panties and, legs now spread wide, she thrust her fingers in an out of her soaking-wet pussy. Making sure to time her penetrations to match Hornier’s thrusts, she soon felt a powerful orgasm grow within her. Unfortunately, she never got a chance to climax.
“Oh yes!”
“Oh god!”
“Oh fuck!”
Barbie’s moans echoed throughout the room. They had grown so loud it was only a matter of time before their mother heard them and came to inquire. Terrified at the thought, Barbie put an end to her auto-erotic sex session and hurried toward the interspecies couple. Placing her hand over her sister’s mouth, she managed to keep her powerful moans contained.
Barely even noticing her sibling’s hand on her lips, Barbie continued moaning as she felt a powerful orgasm grow within her. Only another few thrusts were required before she climaxed.
“FUUCCCKKKK!!!!!” she moaned at the top of her lungs. At least, that is what she would have said if not for Barby’s palm pressing down upon her lips. As a result, only a muffled moan ensued. However, that did not keep her pussy from starting to shake and shiver. Moments later, the first wave of cum flowed up her cock-filled vaginal canal.
Before the sweet nectar even made it out of the teen’s body, her lover’s first wave joined it. Hornier’s cock had started to convulse moments earlier and he now released the first in a series of powerful squirts. The human and canine cum mixed, creating a blend of sweet interspecies orgasmilk; a blend which was soon sent fling past the birthday girl’s labia. Splitting into tiny drops, the gooey liquid flew in all directions, adding a third layer to all three individuals present. The only living being within range that remain cum-free was the small hummingbird that watched the entire spectacle unfold through the nearby window.
Moans, grunts and howls echoed throughout the room for the better part of a minute before both lovers felt their final waves ooze out of them. With one final thrust, the canine pulled out of his human lover, moments before his manhood retreated back into his body. Totally exhausted, he lay between Barbie’s legs and took a few moments to catch his breath. Meanwhile, Barbie did the same. At least, as soon as Barby had removed her hand from her mouth.
The next few minutes were spent in silence as all three individuals present took advantage of the momentary pause to recover from the insane events that had just taken place. Barbie took this time to reflect.
“Oh fuck!” she mentally gasped when she realized she had just lost her virginity to a dog. Of course, she had previously thought her virgin life had come to an end the moment she had climaxed as a result of the puppy’s skillful tongue dance. However, the orgasm had been more a result of her furious finger-fucking than her lover’s eager tongue strokes. Of course, that meant Barbie had only just lost her virginity. Upon realizing this, she felt shame wash over her. She was a lesbian. How could she have lost her virginity to a dog?
“Barby!” was the answer she soon came up with.
It was true, without Barby’s perverse dares, Barbie would still be a virgin. However, there was no way to change the past. Luckily, there was a way to change the future. At least, her sister’s future. Peering at the clock that hung from the far wall of the room, Barbie realized her sister’s half hour had just come to an end. That meant she was now in charge and could dare her twin to do whatever she pleased. Upon realizing this, she let a wide smile curl her lips.
“What are you so happy about?” asked Barby, somehow feeling like she would not like the answer. Sure enough…
