"Can you stop?" Grimm asked, while Ulifer was playing with his hair, making him a little uncomfortable, but at the same time nervous.
"Why? Don't you like it?" Ulifer said with a smirk. Suddenly, he grabbed the other man by his waist, making him look straight into his yellow eyes. (Ulifer has yellow eyes in my headcanon, so yeah-)
"O-Of course no!" The father started blushing, trying to pull off of Ulifer, but that just make the other to cornered him in the wall."Well, your blush says the contrary~",Ulifer took the father's mask off, to reveal a man with green eyes and black hair.
"H-Hey!" The 'Child predator' started to kiss every spot on Grimm's face. After a minute, Ulifer fell to the other's neck, leaking and kissing that part. At this point, the father was shivering and giving little sighs.
"NgH~!", Grimm complained when he felt the contrary bite his neck, then feeling how Ulifer slowly slipped down his pants.
This will be a long night...
