Will the elder sister give birth and fall into madness!?
Will the younger sister give birth and become insane!?
Giant Cocks! Disgusting Dicks! Fiendish Phallus!
Their fragile bodies utterly obliterated by a torrent of cum!!
They will cry and scream to the rape as both their bodies...
and their souls are eroded and corrupted by depravity!!
Their wombs will not rest! Their mind knows no peace!
How long can they last before descending into lunacy?
The relentless storm of violation will turn their minds to the darkness and their bodies into fleshy birthing objects!!
