Both Lily and Luna had fought many monsters, along the way to find the lake somewhere here, but Instead they were now both drenched in all kinds of fluids, some disgusting than the last. Lily could have sworn some of the monsters they fought used their semen to attack them.
But had banished even the prospect of that happening out of her mind, before she loses herself, and goes on a rampage to hunt down all monsters related to that kind, and kill them off, until there's not even a single semen wielding monster in existence.
It's lucky that watching Luna trying to suppress her desires was enjoyable, so much so, she didn't even spare any other thoughts other than to torment her further, by touching her, leaning close to her, and whispering seductive sweet nothings in her ear.
