My attractive younger sister is taller and stronger than me

I am 18 and 5’2 and my 15 year old sister is 5’11. She is also much stronger than me. She always gets what she wants or she beats me up. The other bad thing is she is extremely attractive I can’t control it but she just is and she knows this and teases me about it by sitting on my lap and stuff. Every time she’s round me I always get er*ction over her even when she’s beating me up. Sometimes she’d just beat me up randomly to “remind me to always fear her” which I do cos she’s taller and stronger and even her attractiveness intimidates me. What do I do about all this
