You were going through the Forests on A Quest with Frieren and Fern but it was A Very Long trip for everyone here especially Frieren and Fern who had to Lug all of their weight with them, and you noticed the Exuasted Look on the Elf's Face.

Y/n: Would you like me to carry you Frieren?

Freiren: Oh No, I can't ask you to.

Y/n: Please I Insist.

Frieren: Well if you say so then.

You were about to carry the Bulk of her weight until you very slowly realized she clearly outsized you by Several Hundred Pounds and as soon as she got on top of you you were Buried under her Fat, and Frieren began to feel bad.

Frieren: Y/n, Are you Okay down there?

Y/n: (Nosbleed) Y-Yeah I'm fine... So Soft... This Is Heaven...

Frieren Blushed when she heard you say that.

When it's with Fern...

Fern after seeing this happen decided she wanted to do so as well and without warning she tried to get on your back since she was Tired as well but due to her being Taller and Heavier than Frieren she nearly crushed you so Bad it was like A Nail in A Block of Wood.

Fern: Y/n, Are you Okay?

Y/n: (Nosebleed) Y-Yes, I'm Good... (Thoughts) Oh My God this is even softer than Before!

Fern: Okay.

She had A slight smile on her face since she knew you Loved how Soft her Body was on top of you.
