My sister and her good friend came home to our parents house pretty drunk. Her friend is an average girl but not bad looking. I heard something bang the wall in her room so I went in to her room. I saw my sister eating her friend's pussy. I got a hardon fast seeing that and her friends nice little tits. I was in underware and my hardon was quite apparent. Her friend said take that dick out and jerk off for me. My sister said no get out but I pulled my dick out and jerked off in front of her friend anyway. My sister watched me too. I shot my cum on the floor, my sister said now get the fuck out. So I did. A few days later I asked my sisters friend to have sex with me, she said dream on jerkoff. I was so humiliated.
You should have just shoved it in your sisters ass but only when she's drunk and you already have something on her like being a weekend lezzie
Better yet -- pull up a chair and enjoy watching your sister muff dive.
Next time don't ask. Just take it out and spoog on her. Don't touch her but let her see it again that cock tease.
