It was clenched as firmly as the tiny hole made by your index finger when you make a fist. If you actually try inserting your left index finger into that small hole created by lightly clenching your right hand, you'll understand just how tight it is. It hurts the skin between your finger and nail if you push too hard. Since it gets that tight without much force from the right hand, even while unconscious, this thin-assed elf's anus must still be incredibly tight.
Guh…
It should loosen up little by little, but… still, why is her anus so tight?
I don't know her actual age, but she looks like a middle or high schooler. Even if she has no experience with anal play, is it supposed to be this tight?
…Oh, right. Elves probably don't excrete much due to their diet, so their anal muscles stay firm. That's why, even though her butt cheeks are soft, her sphincter is squeezing down hard. It's probably like gripping a loose onahole with full strength.
Guguh…
