For a long time humans and succubi have always been against each other, due to the succubi's ability of being able to wring out the life force of a man through sexual acts it made things hard to send in men to fight them off whenever they would invade a city, not to mention that they can also easily disguise themselves as any average woman. It's only been recently when humans and succubi have finally been able to live together peacefully, however you still often hear about how a succubus can lose control and accidentally suck the life out of the man they are together with.
While these cases are accidental there are still, of course, some succubi who go out of their way to purposefully suck the life out of someone

"Alright, I'll see you guys tomorrow!" I wave goodbye to my mates as I'm walking out the door of the bar we had been drinking at all night. I visit this bar frequently since it's not that far from my apartment, as such I always walk here and back whenever I need a good drink. However when walking back to my apartment I notice something almost shine in my peripheral. I look across the street and see this beautiful women leaning against a wall.
She had long, dark purple hair, big D-cup breasts, a sweater outfit that wrapped around and cupped her breasts and somehow left little but also a lot to the imagination, plump thighs in stockings, and dazzling green eyes. For a moment when I was checking her out we made eye contact and it almost looked like something sparked within her eyes.
After that I quickly looked away and continued walking back to my apartment. I like to take a shortcut through my local park to get to my apartment quicker, usually there are some people still in the park even when I walk back this late in the night but there was no one else in the park tonight which made things feel oddly empty. I couldn't stop thinking about the woman I saw earlier, she seemed so beautiful.
As if summoning her, I noticed that the same woman I saw was sitting on a bench in front of me. When she looked over and saw me coming she smiled and stood up. Then all of a sudden my body stopped, something felt off about this woman now, as if she wasn't safe to be around, but then she spoke.
"Oh, aren't you going to come closer. I have something very special to give you." In the most sweet and seductive voice I have ever heard she prompted me to come closer to her. I could feel my body loosen up and felt my pants get tighter. I looked down to see that I was presenting an erection and that's when it clicked to me that this woman was a succubus, it would explain the feeling I had just seconds earlier. I tried to move away from her but my body wasn't listening to me anymore, instead I took one small step forward towards her.
I was screaming in my mind trying to get my body to go in the other direction but it was as if my body was only listening to my cock and it was being drawn towards her. I was doing small thrusts into the air guiding me forward until my body stopped right in front of her. She got down on her knees and placed one finger on the tip of my erection, slowly going down to the base. A shiver went down my spine and I let out a moan. I'm not a virgin, I have had sex before but the pleasure I felt from this one finger sliding down my cock was something entirely different.
"As a succubus I can change how much pleasure someone feels. I can make them feel really good but make them able to last a long time, or I can them feel really good and have them cum almost instantly just from the touch of my finger." As a demonstration, she moved just her finger from the base of my cock back up to the tip and a surge of pleasure shot through me, I let out a moan and came in my pants just from the touch of her finger. She giggles to herself and says.
"I hope you lived a good life because today is your last day in this world." Before giving me a seductive smile "W-what." I say "I-I thought humans and succubi lived peacefully now."
"Oh they do..." she said "But that takes the fun out of things, I like to look into the mans eyes as he realizes he's going to die when I do it with them." Her eyes start glowing a deep green, wings pop out from her back, horns grow in a spiral on her head and a long tail appears above her waist, her true form being revealed. She stands back up and gently caresses my cheek. Her hands were soft and she stared into my eyes, being able to see the fear but also excitement in them.
