Ahsoka goes looking for her Master and stumbles upon Anakin and Padme having sex and ends up sticking around to watch

bonuses:
+Ahsoka having alien biology
+Ahsoka watching Padme more then Anakin (bisexual or lesbian Ahsoka is my headcanon)
+the sex being surprisingly sweet and Ahsoka is surprised at how Anakin is basically worshiping Padme's body
