Succubus Sussie excited to help people cum their brains out! (hopefully you pop in seconds from praise and handjobs, otherwise she might think you need a prostate pounding and shocking to dump your nutsludge!)
intestine is kinda easy
depending on what kind of thing you want to depict, an intestine can be just thick long asusage like this
one thing you should remember is that intestine if cut open would sorta burst out of your body since its packed in a nice little compact shape inside you, so any big cut would have them spilling out easily!
image is pretty old but this should somewhat help hopefully!
