Invader Zim (Zim x Dib Rp)

Heat {nsfw}

Zim wasn't feeling well for a few days and decided to stay home until he got this unbearable urge to go find someone. Of course, not knowing what to do, he went and found Dib, sneaking through his bedroom window in the middle of the night and scaring him half to death by accident. He tells Dib what was going on and how weird he felt and Dib manages to narrow it down to him being in heat..

{Also, on a side note, anyone want to rp Red x Purple (preferably au cause I still don't understand what the Tallest are for-)? Just DM me or comment if ya do!}
