Your aunt comes in to spend some time with her favorite nephew and you quickly notice she's not wearing a bra. You can't help but stare, but your aunt pretends not to notice, you decide to take it a little further and see how she reacts, you pull up her top exposing her breasts and she still doesn't really say much... so you continue and pull it up until her breasts are completely exposed, you then wonder if she's wearing panties and reach underneath her skirt and feel for her pussy. You start fingering her, and she takes notice but doesn't stop you either. You take off your pants and tell her to sit on you, then you fuck her from behind and have her finish you with a hand job and blow job. She acts as though none of this is happening, and tries to stay casual. Later on that day you see her napping on the sofa and notice again she's not wearing any panties, you again take advantage of the situation, your aunt again... acting as though nothing happen afterwards...
