My sister is nasty
well iam nethan 19 years and my sister Emmy 19 too (Twins)
it started when i was 17 when i got out of the shower i saw my sister watching me and said to my self "this isn't good"
she watched me when i get out of the shower for about 2 weeks so i didn't care any more
well the third week and this time i found her in front of the bathroom door
so i said "Emmy what the hell is wrong with you"
she said nothing suddenly i found her hands on my towel well so i had to do something
i pushed her away and she seemed enjoying it and i never will hurt my sis
so i ran to my room next time again i found her in front of the bathroom door again and this time she made it fast and quick she removed my towel and looked to my cock and started to happen every time even if iam showering while she's sleep how does she know well i don't know but the only thing that iam sure of i have to be quick and i always though "is my sister that bad?"
