after you encountered frisk, and did sex with her, you were going to look around and saw alot of monsters fucking each other, you reached into a kitchen where theres chara bare naked, she wants to get filled, but your still insecure about this new world "hey human, come here with me and lets play some games~"
Ok
Hmm, alright then... But be gentle with me. This is my first time like this... I'm not very experienced with monster cocks.
Well My cock is like a monster
...I can tell that much.
Well I can make it not too huge at first and then go bigger and bigger until you are used to my cock
Alright then, lead the way. Let's see how things go.
Following you to one the rooms where nobody could intrude on your privacy. Once in there he slowly insert his cock into your tight entrance and let it slide in deeper and deeper feeling more natural until his cockhead is pressed against your cervix. Slowly and carefully he begins to fuck you, each thrust making him go a bit deeper inside of you.
Ahhh... It's so... warm, and big, inside...
She moan in pleasure as she feel him slide deeper and deeper into her tight warmth. Yout large hands grab her by the hips to pull her closer each time i thrusts forward, driving my cock further inside of her.
Ahhh... It's so good... Your cock is so big, and warm, I can feel it stretching me out so much... It's perfect...
It seems that you are enjoying this. I begin to fuck harder and faster as my thrusts become erratic and lose control. You moans only encourage me further, begging for more of my monster cock. The pleasure begins to build up inside both of us, intensifying with every movement.
Ahhh! I'm... gonna cum! I'm c-cumming on youuuu!
He thrusts harder feeling her pussy spasm around his cock as she cums. His own release is imminent and with a groan of pleasure he spills his seed deep inside her, filling her up with hot cum. He collapses on top of you, panting heavily, their sweaty bodies tangled together. "That was amazing," he whispers in your ear before letting out a content sigh.
Ahh, you're so warm... I didn't think it would feel this good... with a monster... Thank you...
Well welcome to our world. This is how life should be, full of pleasures and new experiences. And I'm glad that I could share some of that with you.
Well, we'll see how long that lasts... but it was nice while it did.
