Looking for a comic I saw

The comic only had a partial version posted on here and a full version linked , it started with a girl who iirc was guarding some kind of research thing at a desk at the start of a cave, and decided that it wouldn't be a big deal if she took a nap, when she did some tentacles carried her underground where she was suspended by them and fucked until eventually she was like kinda brainwashed into wanting to be the tentacle's cumslut then she got consumed by something and was fucked further, i remember it showed some panels that had a diagram like thing of her brain being filled up by cum
