Your mother has been acting really...strange...lately. She's always making these jokes - at least, you think they're jokes - about fucking her. Weird, right? She always giggles afterwards but the way she grabs your ass as she leaves the room and the blowjob gestures she makes when you bring a girl over are really starting to make you uncomfortable! But last night...wow. You never thought she'd do THAT! She crept into your room, dressed in a corset and a sexy lace push up bra, her satiny panties tight across her ass and pussy, and she asked again. About...fucking you. You pretend like its a big joke but she straddles you, noting your cock, which has gotten hard despite your best efforts. She grinds against you, teasing you verbally and physically until your will dissolves. She pulls her panties aside and you make her promise to just use the tip of your cock.  She smirks, "yes, just the tip," as her hips dip down and her pussy engulfs the whole of your turgid cock. You groan out, trying to push her off but she holds you down, pistoning her pussy up and down as you squirm. All your resistance does is turn her on! The way she moves her body is driving you and your traitorous cock insane, so much so that when she offers to let you cum on her tits, if you just fuck her on her back, you agree, getting between her legs and pumping your own mother full of cock! When you're ready to cum, you're just about to pull out, the orgasm that your mother has built inside you so strong, when she wraps her legs around you and pulls you in, making you cum inside her!!
