Η ετεροθαλής αδερφή μου δεν ξέρει να φιλάει και γι' αυτό της μαθαίνω

My stepsister says she doesn't know how to kiss, but I think the opposite; Maybe she says that so I can teach her and she can have the excuse of kissing me. That's probably why, because she loves feeling my tongue inside her mouth.
