A look of sheer lust crosses her face, and one of disgust crosses yours. This foul, disgusting monster that's just crawled from your rectum seems interested solely in "pleasuring" you, and you can see her incestuous thoughts in her eyes. Still weakened from her birth, all you can do is crawl back as you nearly retch from how horribly wrong this is.
Your "child", clearly of another mind, has already descended upon you. You continue your struggles, but you can barely move and she's so fast, so nimble. Before you even realize it, the sensual touch of her latex trunk on your fully erect penis, massaging it in a way that human hands, human flesh, never could. You try to push her away, but she merely grabs your wrists and gently holds back your attempts. Finally, you feel a new sensation, a wetness of sorts as her mouth envelopes your erect member. A shudder passes through you as her long latex tongue slowly rubs the length of your shaft, as she suckles on it like a calf. Despite your best efforts, you're helpless to stop this rape, and can only sit idly by as a load of semen bursts forth into her mouth, the constant simulation causing it to fire off in an instant.
In any other situation this would have been pleasurable, but you're far too sickened by this terrible beast forcing you into such blatant incest to find any delight in it. You watch as she draws back, having swallowed your cum, and can't help but feel an incredible satisfaction as she appears to choke on it as it makes its way down her throat. As much as you yearn to stay and revel in this suffering of hers, you know this may be your only chance to escape. Shooting one last look of contempt at your "offspring", you pull on your pants as quickly as possible and flee into the night.
