You, as well as other Sans Au's, have been invited to his pool party, altough, Lust has been pretty intrested in you lately. Still, you arrive to the place, and see most others already swiming, yet Lust was there, and imidatly greets you.

"Hm?, oh hey!, you actually did came!, i expected you not to, but im glad you are here..."

His swimsuit barely fit, but you have not much of an option but to ignore that.
