After several hours of pleasuring each other and then several more hours resting and sleeping, I woke up to this.

[You have devoured Two human's and their Souls earning +150,000 EXP and +100,000 Soul EXP]
[Your Soul has levelled up from 34 -> 35]

[You have gained +30 Stat Points]
I almost shot up in fear before remembering that it was just the two that I ate and not Lia or Varia. I don't think I would've been able to jump up anyways as their bodies were coddled around mine. I would've probably also woken them up by accident if I'd done that.
I also realised that all of us were covered in my semen and laying in a giant puddle of it, probably enough to fill up a decent sized pool from what I could tell.
