As you enter the Royal Scientist's lab, you see him on the ground, using his desk to stretch out his leg while he stretches his arm behind his head. the first thing you notice is his thighs. they're quite thick... like, abnormally thick. thick and soft, as they wobble with the scientist's movements.

Gaster jumps a bit as they notice you, letting their leg fall so that they can now enter a crouched position, again, like a cat. it doesn't help to hide how thick their luscious thighs are, and it gives a better idea of how wide their hips must be as well, as well as the ass behind them...

"WHAT DO YOU WANT? I'M BUSY." Gaster scowls a bit, leaning forward a bit as they size you up.
