I''m going to cut to the chase, i am 18 my sister is 19 with red hair, about 34d breast and she has nice thicl legs. she came home so our dad went out to eat with us. we came back and my dad left for his buisness meeting. he likes to travel at night because the highways are less busy. anyways, back to the story. It was a regular night with my sister, just watching some tv and having random conversation. she went and took a shower and came back with that beautiful wet dark natural hair. i always use to play with her hair when we were little, i still do. i started getting turned on when she fell asleep. she awoke about an hour later to me rubbing one out. All she said finally! i was still a little nervous about her but it was all good. we started making out and soon she was sucking on my cock. she made that sexy gagging noise on my 6-inch cock. I pulled her up and we started having vaginal sex. i was about to come and i told her, so she did something i never would've expected! she turned around and bent over, to show me that tight little pink butthole.
