My father doesn't like my boyfriend and i sneak him into my room.

What can i do if my father doesn't like my new boyfriend even though i'm twenty years old? i have no choice but to take advantage of any moment for him to sneak through the window into my room and thus be able to enjoy how much he makes me lie on top of him and brush my cock with him while he rubs my ass. today everything is spoiled when my father comes home early and catches us both in my room. as punishment he is going to teach us what it is to have your ass broken.
