As Ben Tennyson mutated into Humongosaur a surge of unforeseen power coursed through him
Gwen Tennyson watched with captivated eyes as the alien began an unprecedented unbirth
His body contorted in ways unthinkable to humans a raw display of alien form
The air crackled with erotic energy as the process reached its zenith leaving them both changed forever
Gwen felt an unbidden urge drawn to the primal display
The unbirth was not just a bodily change but a otherworldly awakening
Their bond deepened under the veil of this illicit act
The memory of the unbirth would linger them a hidden shared between cousins
It was a moment of obscurity and revelation
Their connection forever branded by the alien experience
A bond formed in forbidden desires
