I sniffed my ex girlfirends sisters panties.
So went out with this girl back when i was young(16), then 2 years ago when i was 21, i was staying at my exgirlfriends house (others where there, nothing was going on). I didnt have feelings for my ex then, and i was sleeping in her sisters bed. i noticed her used panties on the floor and masturbated with them.
Since then i have kissed my ex girlfriend and really starting to like her again, but i cant help but feel guilt every time im with her or flirting with her. It was her sister after all
