Accidentally Fucked Again

You decide not to tell your muscular futa aunt that she had fucked you to within an inch of your life without realising it. Not only would that be embarrassing, she might want to do it again. It had felt amazing, but that body of hers doesn't know when to quit. You doubt whether you'd be able to take another fucking like that.

You play it off the next morning. The soreness you're obviously feeling? You slept at a bad angle. The fact it's your ass that's tender? They don't need to know that. Instead, you listen to Aunt Abby talk about the most amazing wet dream she'd ever had. Her story fills you with an intense heat. Does she really have no idea? It had been so intense, unable to do anything as she had violated you, and she hadn't even realised what she was doing. Part of you hopes it happens again. Part of you is scared it might.

Abby said she was going to help you buff up over the weekend and she keeps her promises. She sets up a workout mat in the loungeroom in front of the TV and gets you started on some basic stretches. You're not sure if aerobics will make you buff but it does help get rid of some of the knots in your muscles from the night before.

When night comes again, you tell Abby that you'll sleep on the couch. You try to break it to her gently: No! It's not about her. You just stay up later than she does, so you'll camp out in the loungeroom watching flicks until you get zonked and fall asleep on the sofa.

The plan goes off without a hitch. You're rugged up on the couch browsing the selection of TV shows and movies. No shared bed, no Aunt Abby, no chance of sleeping sodomy. You're patting yourself on the back for thinking ahead when you hear the floorboards creak.

"Abby? What are you doing here?" you ask.

She doesn't say anything. She doesn't even look at you. She merely walks over to her exercise mat, which is still on the floor in front of the TV. She's buck naked, the way she sleeps. She looks over in your general direction and says something like, "Come on, Doug. Let's workout." You get off the couch and walk over to her.

"Abby, it's the middle of the night. Can't this wait till tomorrow?"

If she heard you, she doesn't show it. Instead she starts stripping your clothes off, and throws them away.

"You need to wear the right clothes when you exercise," she murmurs. "Here, put these on."

She stretches her hand out to you, but it's empty. Confused, you take a closer look at her face. Her eyes are half-lidded, almost closed. You wave your hand in front of her face.

"Aunt Abby? Hello? ... Are you sleepwalking? ... Oh no."

You realise the danger you're in. You turn to leave but feel Abby's vice grip drag you back to the mat. Suddenly you're kneeling on the mat in front of her. She's holding onto your shoulders, keeping you in place.

"Okay, Doug. First is squats."

She starts off, bending at the knees and moving her hips back. Each time she comes back up, her groin rubs against your face. At first, it's simply annoying, but after a short while you see her cock hardening. Eventually her full footlong is smooshing into your face with each repetition.

Finally she stops and let's go of your shoulders. You try to run but you trip and fall face-first across the workout mat. Then two powerful arms plant themselves down on either side of you. You try to wriggle out, but you can't. You are pinned by Abby lying on top of you. Her rock-hard cock is hotdogging your ass.

"Okay, Doug. Get in position like me. Next is push-ups."

You try to wake her up, or yell for help but the wind is knocked out of you when she pushes down. Her body crushes into yours and her cock slides along your ass crack. When she lifts herself back up you make one final effort to buck her off, but your frame is no match for her taut muscles. She bears down on you and, now that you've tried forcing her off with your hips, your ass is in just the right position for her.

She slams into you. You lose your breath. Your body shivers as your butthole is pounded into what feels like a warm puddle. Soon you can't feel your lower body anymore. It's been turned into a receptacle for your aunt to fuck her sperm into, and she doesn't even realise it. Not even when she cums.

"See, Doug," you hear her say between thrusts. "Exercise feels... Better than sex."

You moan uncontrollably. She keeps going. All you can do is hoarsely whisper:

"Abby, p-please... *GASP* Wake up! Stop! Ugh, god, n-not again..."

You accept there's nothing more you can do and try to melt into the hard foam mat. That's not hard; every bit of you is being pounded down. It would almost feel like a massage were it not for the massive she-cock ramming into your entrance. She cums in your ass a second time, but keeps thrusting. Your entire body feels like jelly now. Eventually she cums a third time, and this is the biggest one. She grunts and grabs the back of your neck, pushing it down as she grits her teeth. She unloads into your wrecked hole and groans like an animal. Everything is heat, sound and pressure.

Suddenly she pulls out. You still can't feel your legs. You doubt your asshole has stopped gaping; your back passage is stuffed from the loads she's just pumped into it.

Faintly you hear, "Good workout, Doug," and some footsteps fading away. Then you black out.
