Something important to understand about succubi is that some variants produce venom, which naturally acts as an aphrodisiac, but also that some variants continuously produce venom. What that means is that, depending on the species, your summoned sex demon might well just need to get that venom out every now and then! Left undrained, our venom sacs will continue filling, eventually swelling and causing us pain and discomfort. In extreme cases, our fangs might even start leaking venom. So really, it's just responsible summon care to let me drain my sacs into you every now and then. Don't worry, you'll get used to the endless burning urge to get off that orgasms barely provide any relief from....probably
Now on the other hand, there are options if you're a more assertive, take-charge type, and the ladies don't want you to know this so you didn't hear it from me, 'kay? The thing is that draining our venom sacs is utter bliss for a succubus, just an incredibly pleasurable experience, some have even reported being able to achieve orgasm through sac stimulation alone! Yes, that's right, you can manually stimulate a succubus' venom sac. Mine are located in my gums, see? Anyway, if you don't want to become your succubus' mind broken venomslave, for some reason, they do make milking machines that safely stimulate our venom sacs and drain the resulting product into your desired receptacle. I've known girls that got caught and kept for years in a machine like that, and they've all described it as a positive, if deeply humiliating, experience! One even had her own venom hooked up to an IV that fed it into her bloodstream, which definitely had quite the effect on her!
.......why are you looking at me like that?
Me summoning my succubus for the fourth time today.
