My SO sister [mf]

Just got home from vacation with my SO and her family. I shared a room with my SO and her 18 year old sister, I’ll call her N. I had to sleep on an air mattress because my SO’s parents wouldn’t let us share a bed… so before bed I was talking to my SO and say her sister spread open her legs and flash her red panties real quick. It was pretty apparent that she “accidentally” did that. So I go lay down and my SO falls asleep( she sleeps like a rock and never wakes up) so I’m laying there thinking about what just happened and boom, raging hard-on. So a little bit time passes and N gets up to go change to her night close, she walks right over me and my hard cock, she must’ve saw that I was hard. She came out of the bathroom and “fell” over the mattress and touched my dick, she stayed there for a minute before getting up. That was the most for the first night.

The next day all come back from the beach to shower and get ready for the day. I usually shower first because I don’t take that long. N showered next. After her shower she was in the bedroom with just her towel on and it slowly was slipping down revealing her nice D tits. God they were so nice. She looked at me and saw me staring she just gave me a sexy smirk and tried to see if I was hard. I was so hard. So that night I get the idea to just sleep in my boxers and have the blanket “fall” off when I’m sleeping. N finally gets up to go to the bathroom and on her way back she finally sits down next to me and grabs my dick. She looks me in the eyes and quietly and in a sexy voice ask to see it. Fuck I wassnt about to say no. She pulls my boxers down and i can tell by her face that she likes my hard cock. She told me that she hasn’t seen a dick this big( I’m a solid 7”) she starts stroking me slowly at first and then faster. Out of know where she wraps her nice warm mouth around the tip. I wassnt expecting that at all, I almost came right then. She licked from the tip to the balls, all why stroking my dick with her other hand. After about 10 minutes of an amazing blowjob I finally blow my load all down her throat; she swallowed it all. Hopefully I can get her to do it again.

Sorry if it wassnt well-written.
