“Oh! Give me more!” Alison managed to scream. Jen, too blinded by lust to think clearly, quickened her
pace, ramming as much as she could of her now 13-inch monster cock tongue into her sister. The experience for
Jen was electric; as sinfully delicious it was to take her virginity herself with a cock that was bigger
around than a man's wrist, it was doubly so to do it to Alison. Alison was so tight that, even though she was
much more wet than Jen, the juices literally couldn't go anywhere. The sight made Jen jackhammer her own
pussy, driving 3 fingers in as far as she could into her own wet snatch.
While the sisters made love to one another, the curse was busy doing its own dark work... Memories were being
changed, personalities altered, history re-written to accommodate Jen's new freakish state. All in a day's
work for this ancient and powerful magic.
Alison bucked and tried to grind against Jen's monster organ as best she could. She came first, finally
having achieved her dream of fucking her big sister, added to the overwhelming sensations of being plowed by
this monster cock, driving her clear over the edge. Jen came just as Alison's pussy clamped down on Jen's
penis, pumping her seed over and over into her little sister. Just as before, Jen's giant tits contracted as
they spewed hot cum deep into Alison; this drove Alison into her first multiple orgasm, and made Jen come
again, this time from both sexes... Semen trickled around her huge cock as it fell out of Alison, each spurt
making a wet sound in Alison's too full pussy. This continued for what seemed like forever, until Jen finally
collapsed from exhaustion, and Alison followed soon after, too tired and sore to move.
When Jen finally awoke, she felt the sleeping nude figure next to her. Opening her eyes, the aftermath of
what had happened came to full view: the cum-soaked floor, Alison leaking Jen's spent seed from her cunt,
Jen's own pussy still dripping with semen... She had fucked her own sister and came inside her!
“Oh my god Alison, I am so sorry. I had no idea what came over me!” Jen panicked in her mind; what was she to
do? What if she got her sister or herself pregnant from these escapades? Why would she do such a depraved
act?
Alison laughed. “Seriously sis? You know I've been trying to get at that monster dick of yours ever since I
hit puberty not too long ago. Did you like that innocent act? You really must have been out of it after
taking your own virginity... You fake being sick with Mom all the time and then go on day long masturbation
sessions... Have since you hit puberty yourself... Though I had yet to see you try to fuck yourself. That
was hot.”
Jen thought about it a moment. It was true, she HAD been doing this for a while. Wait, that's not right.
But... It was. New memories flooded Jen's mind, overlapping and existing parallel to her old ones. It was
delicious. It was wrong. She was deeply conflicted as her old self freaked out at doing something she'd
never have done in a million years.
Jen's thoughts were interrupted by Alison, grinning wickedly at her. “Hey, Jen... Ready for round two?”
Jen's cock erupted forth from her mouth once again, growing to its full size, then with a final throb, adding
on another inch. The only sounds that could be heard throughout the house for the next several hours were
Jen's muffled, animalistic moaning and Alison's stilted screams.
Alison was busy trying to ride Jen's tongue-cock when...
