"You can't be sneaking pictures like that of me, or your step-sister," your step-mother says, after sitting down for a talk. You wish you could focus on anything but her figure, her breasts inside her tight sweater, but you've been lusting after her for so long. And its not like she hates the attention. You can tell she likes it, that finding those pictures of her on your phone was exciting. She can pretend that's not the case, but you see it in the way she touches you, reassures you that sexual thoughts aren't inherently wrong. The way she tucks you in, rubbing up against your obvious erection...the way she nestles in even as she protests your hand sliding up her thigh, squeezing her ass. She can pretend, but not for long. Not for long, before she reaches under the covers and squeezes at your hard cock, slowly starting to stroke, then suck...then fuck. Your lusty step-mother, riding your dick, just like you knew she wanted.
