This is a loose idea. Could be mostly any heroine.
Basic outline:
Villain has planted bombs around the city.
Heroine tells him he is bluffing.
Villain tells her that he will destroy the whole city if she doesn’t have sex with him.
Villain sets one off, destroying an abandoned building.
Heroine gives in.
Villain tells her she’s got to earn it!
Give him a lapdance
She does so and enjoys herself a little bit. Of course she wouldn’t admit that.
Villain tells her he thinks she’s turned on by this. She of course denies it
He really takes his time with her. Makes her masturbate and then he uses a vibrator on her. She is really losing herself.
Blowjob and be enthusiastic.
He finally begins to fuck her. She is really getting into it.
Her inner monologue says how this has always been a fantasy of hers, being fucked by a villain.
He tells her if she wants to cum, she must tell him to detonate the bombs
She is so lost in lust she barely hesitates. All she can mutter is “do it.” He tells her she will have to speak up and she yells “do it! Please just do it! Make me fucking cum!”
He sets off the detonator, the camera shakes a little as she enthusiastically fucks him back and you can mildly hear explosions in the background. She talks dirty about herself, saying what a whore she is.
When they both cum, the weight of her decision sets in. She cannot believe it but she doesn’t feel bad about her decision.
He tells her she can be his partner and they start passionately kissing
I like this concept a lot!
