Baby-making sex, obviously

"With your pussy, please"

With a bit of a shy look on her face, Toriel begins to strip as you take off the rest of your clothes. She's an even bigger MILF than you thought, with masse breasts and a plump butt

She seems to wanna take this slow, but can't hold back. You line yourself up and just slam her ass with your massive cock

"Wait, don't AAHHHHH"

Her protests are quickly silenced by her moans as you stretch her pussy wide. If she wasn't a mother, you'd think she was a virgin. But then again, you yourself are a virgin, so what do you know? You keep plowing her to the sound of her escalating moans, each trust hitting her cervix

It's just an amazing feeling, her pussy squeezing around your cock, her tits bouncing in front of you. You'r certainly never going back to porn if this is the alternative. Soon, you feel your end approaching. "Miss Toriel, I think I'm gonna cum!"

"W-wait! Do it outside! Today isn't a safe day!"

"Don't worry Torriel, you'r a good girl, I'm sure you can manage" you say with a malicious smile before you release inside her fertile pussy, your cum quickly overflowing her womb
