Just a few days ago my sister-in-law who is 15 spent the night I was up late watching tv when I was heading to bed I heard some noise from the room she was in.

I looked in and she was playing with her self I should have walked away but I watched her I walked in and she got scared I told her that she can keep going she seen my cock poking out my boxers.

She got up and sucked my cock then I was thinking holy shit she's 15 and she's my wife's sister my kids aunt and then she told me to stick it in so I did I know she has sex my wife told me she's on birth control so I don't hold back 35mins of me pounding her pussy I bust a huge load in her and she whispers I came 5 times I kiss her and go to my bed where my wife is still sleeping.
