(Her Secret Fantasy, continued by TrickyDick...)

“Well then, why don’t you bend over and let me fuck that fat ass of yours?” you decide.

Ashley playfully slaps you and says, “Young man, do you kiss your mother with that mouth?”

“Well not yet, but maybe when I’m done with you I’ll pay her a visit,” you reply as she lays on her back. You look over at your mom whose lips are wrapped around Jamie’s dick as a few of the guys from the football team are lining up behind her. She catches your eye and gives you a wink before taking your best friend all the way down her throat.

“Hey, Ross! Snap out of it kiddo, focus on the ass in front of you not the ass down the street,” Ashley chides. You look down at her inviting brown hole, and decide she’s right.

You slip the head of your spit-covered dick into her ass. There’s less resistance than you expected, and you think she must have done this a few times. Ashley starts rubbing her clit in circles as you work your shaft all the way up her tight ass.

“Oooh, fuck yes Ross, fill me up,” Ashley says as you start thrusting in and out. “Is this how you thought you’d be spending your day? Fucking your girlfriend’s slutty mom up her asshole?”

“Actually,” you respond, “that was half the reason we put this whole thing together.” You pick up the pace a bit and you feel her anus tighten up around you.

“Oh baby you didn’t have to go through all this trouble for that, you could’ve just called me and asked!” she says as you speed up more and more, causing her tits to start bouncing up and down. “As a matter of fact” — she pulls your head down to hers so that you’re face to face — “if you can make me cum, I’ll give you a key to my house so you can use me whenever you get bored of cumming into my wet blanket of a daughter. Deal?”

“Deal,” you reply, then she locks her lips with yours. Your tongues dance back and forth in each other’s mouths as your hips clap against her cheeks. You can feel yourself nearing an orgasm so you quickly pull out and turn her over so she’s on her hands and knees. You give her ass a smack and dive back in.

She starts moaning in time with your thrusts as you fuck her doggy-style. Every slap you give her ass elicits an encouraging yelp, so you decide to grab a fistful of her hair and pull it back. “Oh fuck yessss Ross, fuck me like you own me…” Ashley moans as you use her hair as leverage to fuck her.

“Oh shit, Ross, I think I’m cumming!” Ashley says, voice starting to tighten and shake.

You see your window and lean down into her ear as you fuck her. “Oh yeah? Are you gonna be a good slut and cum while someone half your age fucks your fat ass?” With that, her eyes roll back and her legs start to get shaky.

“Oooohhh fuck I’m cummiiiiing!” she squeals as you clap away at her ass as hard as you can. She shakes through her orgasm and eventually relaxes, still panting with every thrust from your dick. You feel yourself about to cum…
