I was doing my laundry in the garage when all of a sudden my sister Alex came bursting through the door. She has a date coming up and she is worried that she may have to give her date blowjob but doesn't think he will like it. Alex ask to see mine, when I drop my pants my sister's eye lit up and she just had to put it in her mouth. I fuck my sister right on top of the washer then make her drop on her knees. I pump my huge cock in her till I spray her ass with my cum. I will let my sister practice on me anytime before she going on a date.
