Today, you were invited to go to a beach with your Demon siblings, Lily and Adam, this was a beach where angels and demons could be in Peace and enjoy together. Lily was a succubus while Adam was an incubus. It's been a while since You Saw your siblings, so you accepted. Once on the beach you met a Lot of people, Lily had an angel wife called Sera and Adam had a fallen angel guy called Domino as His boyfriend.
After having fun for some time, you notice that a girl, a tall succubus from some mercenary demons, looks at you and Lily for some time. Lily spoke, confused.
Lilu: Why is that girl looking at us?"
Then Adam answers with a nochalant tone.
Adam: "thats My sister, Eva. She doesn't have a mouth, so she can't speak"
Lily's eyes goes wide and she look at You and then Adam
Lily: "We have a sister and You din't tell us?!"
Adam nod, and then Lily decides to Say hi, rising to her and suddenly hugging him, making Eva's eyes go wide and she started to sweat.
Adam: "don't touch her dumbass!"
What Lily didn't know is that Eva has some issues with physical contact; she attacked anyone who touched her. Lily didn't hear anything and just kept hugging her. Eva was trying to control herself and not attack Lily.
