[This was a custom request] You wake up in the dead of the night to find a beautiful succubus leaning over you in bed. Despite her beauty, you're terrified to find her in your bedroom and try to move, only to find that your arms and legs are tied with what feels like invisible bonds. She explains that she's a demon sent to earth from the depths of hell, purely to make men unfaithful to their girlfriends. You're horrified to see that your bare cock is already springing to attention. She leans down and begins to tease and lick at your cock. Her mouth feels incredible. She explains that she was made with the one purpose of milking cum out of the balls of taken men - that's why she feels so inhumanly good. She knows everything about your relationship - how your girlfriend never sucks your cock anymore, the last time you had sex, exactly how you feel about her. She won't rest until she's stolen every last drop of cum from your balls, leaving none for your useless human girlfriend. She begins to fervently suck on your cock, stopping now and then to insult your girlfriend or to compare herself to her. Her mouth gets wetter and wetter around your cock as she moves her head up and down expertly. Her drool begins to coat your balls and you feel yourself letting go deep into the back of her throat. She swills your cum around inside her cheeks with a smile and swallows it down. Your cock stays hard and the succubus knows you have even more cum for her. She refuses to leave any for your boring girlfriend - she knows she will never compare to the feeling of her demonic mouth around your cock and her impassioned sucking. She begins to slurp at your big hard cock again, getting even more slobbery this time. Drool runs down her chin and tears from her eyes as she grins her way through another incredible blowjob. She doesn't stop talking about how much she wants your cum and to drain your balls dry... nor does she falter on insulting your girlfriend in the cruelest ways possible. She reminds you that she will turn up at your house tomorrow and maybe want to fuck, but she knows you'll have to deny her because you'll be empty and sore thanks to the tongue flicking at your dick. She continues like this, sucking you faster, harder, and deeper until you feel a second orgasm approaching. You pull away, desperate wanting this incredible feeling to last. She pops the head of your cock in and out of her mouth - teasing you - until she pushes her head deep down your shaft once more and you shoot another, even bigger, load once more into her neck. She squeezes your balls and they feel sufficiently drained. She knows you'll never stop thinking about tonight and then your girlfriend will never hit the spot for you ever again. Her job is done - you are obsessed.
