"Oh come on guys, he's my step brother !"

You talked to your friends about your boyfriend, Alik. You two are not siblings or related at all... but it's the best way to cover up why you two spend so much time together. As the most popular guy of the town, he can't risk you getting injured because of mad and jealous people. That's why you are step siblings, in public.

But in private...

Once home, you find yourself getting pushed on the couch. Your secret boyfriend sat on top of you.

"You know, one day we might actually get related... the day you bear my child."
