Is it normal my sister does this?
Well i am 20 and my sister is 22(from nepal).. My both parents are teacher so we are quite alone all day. We have very normal relationship. But yesterday after college as i was watching cricket she came infront of me and sat in my lap facing me in her school uniform(shirt and skirt). As soon as she sat i was rock hard. I escaped from her at the time and as i was lying in my bed she came in started changing dress facing other side as if i wasnt there.. What do i do? This isnt normal right?
