Ross could feel it. The primal side of him was slowly taking over, demanding that he pin Samantha down and pump as many litres of cum inside her as possible, which was a sight he was embarrassed to admit he wanted to see. What made it worse was that she seemed to like the idea.
Her breasts pressed into his face while her mid-section tortured his growing cock with aroused excitement. She almost couldn't continue herself, but not in the childish playful way… Instead of the normal childish anticipation she normally displayed, Sam had somehow managed to achieve a low, breathy moan that conveyed a deep sense of lust and burning hunger. The kind that would make any man hard within seconds of touching a seductress.
“Are men supposed to be able to cum that much, or is it another effect of that bug’s bite?” She let out through a needy moan, directing her nipple into his mouth. Her hands in his hair told him how much she wanted him to pay attention to the engorged breasts.
Ross wasted no time, his tongue and teeth lashing out hungrily. The erection he'd been against a moment ago started getting out of control, growing to last night's twelve inches, and surpassing it.
“MM-HMM!!!” Samantha shuddered at her childhood friend's touch and the tantalising pressure of his growing dick forcing its presence to be known, “IT'S SO MUCH BIGGER!!!”
Her voice reminded Ross that she'd asked a question just a few minutes ago. Amidst their tangle of desire, he managed to let out while kneading her last breasts, “How did your body change so much overnight?”
His words created a moment during which his tongue wasn't working. Samantha did not like that. Her body screamed at her for letting it happen, and a moment after he was done with his question, she stuffed his mouth with more than her nipple. Breast flesh filled his mouth and spilt around his face, threatening to suffocate him while she let out a moan, relishing in his struggle.
To her surprise, the dick she'd allowed to grow between her butt cheeks seemed to grow even harder the more she did this to him… and that only doubled how horny she was, considering how much more fun his dick was going to be now, going on and out her walls with so much girth and length.
The possibilities...
“Less talking… more tongue,” Samantha demanded in that same sexy tone that was running Ross crazy.
His mind grew muddled. His hands travelled down to an ass so unbelievably fat and juicy that common sense vanished from his mind.
The primal side was winning. What was wrong with this situation? Why was he worried about fucking Samantha's brains out?
“Fuck!!!” He gurgled.
Samantha let out a moan as his hands sank into her ass cheeks. She pulled her breast out of his mouth and presented him with the other one, this one far more needy from the lack of attention. She even seemed to shiver as she brought over the melon-sized breast and stuffed as much as she could into his mouth. “Be rougher,” she begged in a needy whisper.
His tongue lashed out, and he sucked hard while his hands squeezed her ass hard. A heavy shake ran through her body, “Y-Y-YES!!! LIKE THAT!!! MMM–MORE!!!”
She pressed into him with everything she had, unable to control her arousal anymore. Ross was just about to snap and lose it when he remembered where they were.
He pulled her down with a great amount of energy just so he could look her in the eye, “Our parents will hear.”
“So what?” she breathed, visibly irritated by his sudden interruption, “We're grown-ups, and they do this shit all the time when we're out on trips.”
“Yeah, but…”
Samantha smashed her lips into his and grabbed his hand, directing it to her breast. The other hand, she directed to her ass before putting her arms around his neck and rolling her hips in one tantalising motion that shattered the rest of Ross's restraint.
“Fuck it!” He growled and attempted to flip her over.
She didn't budge. Her hips were pinned on top of him with a midsection so wide it could have weighed his entire body weight, yet so curved he could lose his mind just staring. Samantha rose and asked him, “Like what you see?”
He nodded.
“Good,” she answered with a whisper before coming down, “Because I'm not getting off you until you cum like you did last night.”
He squeezed her ass and revelled in the deep breath she let out.
“I was going to fuck you with me on top, but I guess this works too,” he answered.
She smirked before lifting herself up to receive all fifteen inches of his cock.
There was a bit of a struggle as she descended, but not once did she stop until their hips met. The night before, Samantha had been excited but reluctant, which was a stark contrast to what she was now. Utterly ravenous.
Her walls clamped around all fifteen inches of thick meat, sending waves of pleasure through Ross in ways he never thought possible.
She came down and kissed him some more. This time, her kiss was somewhat passionate, but Ross saw it for what it was. She had what she wanted, and this was her way of telling him she wasn't as good as hers.
This was her way of saying his dick would not leave her pussy until he unloaded bucketloads of cum inside her.
As Ross’s hands explored the immense curves that Samantha had grown overnight, he realised he wasn't entirely opposed to the idea of having sex with her that morning.
That realisation alone made his dick harden even more inside her, a reaction that made her moan into him, “Gods, it's so big!”
