He needs a little push first.

His mouth working soundlessly, mind blank in the presence of the animalistic, titanic rod his sister now sported, James only stared at the gently bobbing monster, the top of which Lily was caressing with one hand. A gentle smile spread on her face and she bent down at the knees to get closer to where James was lying on all fours - or rather, threes, as one hand was still sticking in his cunt. James' eyes followed the blunt giant of a cock as it got closer and closer, until it lightly smacked into his cheek, smearing it with a little cum that was still bubbling out of the slit. It felt so incredibly hot against his face, and the smell... The cow morph took a deep whiff of the overpowering musk, his eyelids fluttering. With a wet slurping noise, James' left hand slid out of his well-lubricated cunt as he brought it up to the throbbing shaft resting on his soft cheek, pressing his palm into its side and smearing his juices over the throbbing flesh. Feeling his sister's thumping heart-beat through the skin, James turned his face to slowly, languidly sliding his tongue over the mottled skin, savoring the salty taste. Lily moved a bit closer, until her head was drooling pre on James' naked back.

"Aww, do you like my new cock, little cow?" Lily chuckled, only a slight tremor in her voice revealing how much she enjoyed the feeling of James' hot tongue worshiping her cock. But James was much too focused on the gargantuan beast in his face to notice. It was just so huge... and salty... Alternating between licking, kissing and lightly sucking on it, James swayed backwards and forwards on all fours to cover as much skin as he could, but only managed a fraction of its impressive whole.

"You know, I could give you even more," Lily cut into her step-brother's clumsy ministrations, making him turn his head to look at her through a haze of desire and need, "But you'll have to tell me exactly what you want, little cow."

His attention now not focused on Lily's monster and Lily's monster alone, James finally noticed how incredibly wet he was. Fluids were slowly running down his thighs, and he could feel the cool air wash over his burning hot lower lips as they gaped open, twitching madly in desire, begging to be filled.

"I--I want you... I need..." James began, face burning with lust and shame - actually saying what he wanted his step-sister to do was so incredibly embarrassing. But he needed it sooo bad!

"What, little cow?" Lily asked, smiling kindly, but a mischievous smile tugged at the corners of her mouth, "I can't help you unless you tell me."

"P-Please don't make me say it," the **** cow morph half-moaned, wriggling his hips, "It's too... oh god, I can't..."

"Why? Do you not want it?" his sister replied, withdrawing a few inches from James, her cock sliding over of his palm.

"NO!" James could not bear even the thought of losing the touch of Lily's cock, and he almost shouted: "I need your cock, I want it inside me, please, you have to FUCK me!"

"All you had to do was ask, little cow," Lily smiled, standing up and stepping around James' prone body into the hallway before he could react. Kneeling down behind his twitching ass, she sandwiched her enormous tool between his ass cheeks. Only now did James notice how much they had plumped up - they easily engulfed almost the full girth of Lily's bestial rod, quivering with anticipation. The freakishly endowed girl slid her burning hot cock forwards until her giant nuts smacked into James' slavering pussy, prompting a high-pitched moan from him.

"Mmmh," his breeding bull-to-be groaned, grabbing James' widened hips and leaned forwards to whisper in his ear, "You feel that, little cow? You feel how far my cock reaches on your back? All of this is going inside you."

Indeed he could. Her drooling cock was dripping slimy pre onto the middle of his back, and the thought of it splitting him open was almost enough for him to cream himself on the spot, a drawn-out, moaning moo rising from his throat.

"This is the last chance to turn back, little cow," Lily breathed into James fuzzy, drooping ear, the tingling feeling making James gasp, "Say the word, and I'll give you every... last... inch."

Her final words were accentuated by tiny humping motions from her hips that made her medial ring rub over James' ass cheeks and her nuts slap into his swollen pussy.
