Hope's monster (+18, monster smutt)

Pleasured by sirenhead

As I was going to pleasure my self one night I found that I heard some siren sounds they were almost deafening but I rarely not to find out.   It sounded very eerie and creepy I must say!  But I was to much into my self that I completely forgot about the siren sounds!   As I was doing  self pleasuring I soon found that I was being made love to by sirenhead!   Yes the sirenhead as in the monster! He was thrusting into me as  I was getting terrified but soon I was getting turned on!   
"Oh fuck!" I screamed.  But they're were not screams of horror nor pain but of intense pleasure!  
Soon he was spilling his essence inside of me as he deeply kissed me as well as the monster could kiss!   I wrapped my legs around him and started to ride too his rhythm!   Soon I was spilling my juices I wanted him to make love to me with that long tounge!   I wanted him to put it in my womanhood!    But he slowly worked his tounge's way from my lips to my bosom to my womanhood!  As he was pleasuring me I found my self spilling heavy into his mouth(s) as he orally made love to me!     Soon I guided one of his large hands on my equally large bosoms and he squeezed as he started to taste!
Bear with me as this was my first time with a monster!  Though I had a boyfriend I was throbbing for more of his tounge and started moaning his pet name. For me!   Was it wrong for me to cheat on my boyfriend with a monster!
But then again it felt so good!  This pleasure was what dreams were made of!  Soon he used is tounge to tease me in parts I did not know I had!   His breath was foul but it was making me spill heavier and heavier in his siren mouth as he was devouring me!  Soon I was going to to feel that rush that only a climax would give!  The adrenaline and pleasure started to waste over me and I screamed as he was eating me, kissing me!  Drinking me!
"Oh sirenhead!" I screamed!   
Was I dirty for being with a monster instead of a human!  I wanted to have his tounge deeper into me as I did I wanted to him o rip my undies off as I as started sitting on him!   Fucking his mouth(s)! 
Then I was hearing foot steps as I was doing my monster!  Soon I was going to deal with a mother monster that I did not want to deal with in a negative way way!  My boyfriend.  
"Lisa what are you doing!" He yelled
It finally rang in my head that he was serious! 
But I was in the through of coupling with sirenhead!  Soon I was too high from the pleasure to realize that my human boyfriend was angry with me and threatened to leave me!  I continued coup,doing with sirenhead!
