I approach cautiously

I try to come closer, with my sword drawn. There's no telling what this higher-level slime is going to do. The pheromone scent of her is overpowering, and as she gets closer, it completely overwhelms my reason. The blue crystal of her eyes gazes into mine, and I am mesmerised. She kisses me then, her lips touching mine, parting my lips and I feel something like a tongue glide against mine. I drop my sword and shield to the ground, as her hands go around my back pushing me against her. I cannot resist. My armour falls away and I soon find myself naked in the moonlight with this strange and beautiful creature.

I am incredibly hard, my manhood like a thick rod of wood as the slime-girl lays down on the ground, spreading her legs apart, fingers caressing her pussy, spreading open the lips, which glisten wetly a bluish green in the moonlight. A distant voice inside my head tells me that I must not do this, this is dangerous, and I have to stop, I have to kill her, but I am powerless to resist and I mount the creature, my dick entering her.

She is warm and soft beneath me as I slide into her, burying my manhood in up to my balls, and she moans softly as I push harder and faster. I can see my manhood through her transparent body, which is somehow more arousing than anything. Her insides contract and squeeze my dick in ways that are likely impossible for even the most trained courtesan, and in a matter of moments, I explode into her, and I can see my seed flowing into what looks like a womb inside her, as she lets out a gasp of ecstasy in time with my own.

What have I done?
