Your step-daughter, the woman that you've been secretly having an affair with for months now, is staying over for awhile. On the first night of your step-daughter's stay, as soon as your wife goes to bed, you sneak off into your step-daughter's room where she is eagerly awaiting your arrival in some sexy lingerie. She teases you a bit, saying how she knows how hard it was for you to not get turned on thinking about her being right down the hallway before your wife went to bed for the night. How thinking of her is the only way you can even get hard when you're with your wife. And it's true. Ever since you started sneaking around with your step-daughter behind your wife's back, you have had no interest at all in your nagging, older wife. And somehow, your wife hasn't even noticed. Or if she has, she hasn't said anything out of fear of losing you. Which is something that your step-daughter finds absolutely amusing. She cruelly puts down her mother even more, and you get even more turned on. Your step-daughter has you show her your throbbing, rock hard cock, before taking it in her mouth. You lay back on her bed as your step-daughter works her mouth up and down your cock. It feels amazing feeling her lips wrapped around your cock like this, especially with how risky it is, knowing that your wife is within earshot and could easily hear your moans if you get too loud. Your step-daughter enthusiastically sucks your dick, getting herself so turned on until she can't go a moment longer without your cock deep inside her pussy. You continue to lay on your back as she gets on top of you and begins to ride your cock. While bouncing up and down on your cock your step-daughter continues to compare her to your wife, while also talking dirty. She knows just what to say, just how to ride you, to drive you absolutely wild with desire. After riding your cock for awhile you can feel your step-daughter's pussy begin to tighten and quiver as she gets closer to cumming. That's when she has you get on top and slam into her. Once on top, neither of you even try to stifle your moans. If your wife hears, so be it. Your step-daughter even comments on how fun it would be to have her walk in and see the two of you together like this. Being this risky all while fucking your hot step-daughter and feeling her tight, warm body beneath yours, it's almost too much for you to handle and you know you're going to shoot a load so big inside of her, that your cum will still be dripping out of her when your wife is cooking you both breakfast in the morning.
