My own sister and Gf lock me out naked

My name is rohan as i live with my family and my parents are out so i thought its a great time to bring my girlfriend . And that become my worst desesion.

So i me and my girlfriend (divya) we are in my room hanging out and out of know were my sister (neha) knock on my door. As i open she ask us do we wana play some game and divya suggested how about truth and dare. First i was against it after some begging of both i also ready to play truth and dare.

As we started it was some silly task and naughty questions only and i tease them that this childish and then the worst thing happen.

I lost and i choose dare as to prove i am being not a childish they give me a embarrassing dare.
