I think my brother fancy me ?

I think my brother has the hots for me

Does my brother have sexual thoughts for me ? when we all used to live together at my mum house, we had to share the same bedroom and i was 17 and he was 18, and when i was in my knickers, getting ready, i can't help noticing my brother was trying to look at me or peeping from under the duvet, as if i couldn't tell he was watching, and i felt like he was doing something under the duvet too, and other times, when he got out of bed, he have his y fronts half way down his bum for some reason and i think he wanted me to see, but i took no notice, when i got up to get ready to go college, i notice my knicker draw was touch, and some of my clean knickers had stains on them and i was thinking, surely he hasn't been wanking into his sister knickers, that is just so wrong, anyway, years later, whenever he came around, he was always happy to see me and give me a hug, and at times, i felt his hug was a big tight and too close, he tells me i am beautiful and can't believe i am single, anyway last week, he came to stay with me, and i was in the shower, and the next i notice, i heard some breathing and i look around and he was watching me having a shower and shouted, what are you doing, get out, he went downstairs, and seems really embarrassed, and now i think my brother fancy me or has weird thoughts about seeing his sister nude, how do i handle this, i now got these thoughts in my bed in my brother seeing me naked, and i am wondering what if, he try to touch me ? do i response and let him or do i just go mad, and tell mum and dad, little does he know he sister show her body naked online, i wonder what he do if he saw my pics, if you was me, would send him pics ?
