The next morning

After your exhaustive struggle with your Aunt and even more exhaustive orgasm caused by her huge prick lodged deep inside your asshole you actually had a good night’s sleep, thanks to her more relaxed grip following the dumping of her huge load of cum in your colon.

When you wake up, however, you can feel your situation hasn’t improved much. Her cock is still tightly implanted in your ass, and it feels just as thick as it did last night. In fact, the way she is rhythmically pushing and pulling slightly in and then slightly out of your ass reminds you of just why you had that orgasm in the first place. Her dick rubs deliciously against your prostate, with every shove of her hips making you moan in barely contained bliss.

“You’ve been a very naughty boy, haven’t you, Dougie?” Her voice right next to your ear makes you shudder, but at the same time, your dick jumps excitedly in response to her surprisingly sultry voice. “I bet you've been looking forward to having my dick inside you ever since you saw me yesterday,” she continues, and you can hear her grinning evilly “and you know, if you wanted me to fuck you so badly, you only needed to ask and I’d have gladly complied.”

You try to explain that that wasn’t the case at all, that she’d **** herself on you with her strong, muscled arms and her stupid, thick cock that’s melting your mind right now, but your voice only comes out as a series of moans as she rams herself harder and harder into you. You can do nothing but moan, trying to form your garbled and pleasure-scattered thoughts into even one coherent sentence, but it's no use. The monstrous cock inside you feels too good, stretching your asshole to its limit and crushing your prostate into the walls of your ass. You feel like her dick will rip you open, but you don't care. You just want more, but you can't even beg for it, you're so out of it.

“But don’t worry," Aunt Abby whispers into your ear, "I’ll - ugh”, her voice breaks a little as you tighten around her, feeling your orgasm approaching, “ I'll make sure to satisfy you, Dougie.” She stops again, this time because your asshole clenched so tightly and with such **** that she couldn't hold out any longer. She drags her dick to a stop, jerking erratically in and out as her dick floods your cavity with cum. The pressure of her dick, spasming inside you, sends your prostate over the edge. Your dick explodes and your ass squeezes her so much she can no longer hold herself back. Her load is so big that you can feel her sperm travelling all the way through her shaft right before it floods your insides. Her nearly constant stream of cum continues for so long, you’re sure your belly has visibly expanded by now.

Finally, as your orgasms both subside, Aunt Abby slowly pulls her cock out of you. She pauses briefly before pulling her head out, clenching one last time to full empty her dick of any cum that might not have made it all the way out. You continue to lay on the bed, face down and completely incapable of movement after your incredible orgasm. Soon Abby stands up, moving into your view to get dressed for her day. You can feel her cum overflowing from your ass, dripping down your balls, and onto the bed as your Aunt starts to cover her gorgeous, shredded body with clothes. She puts on a tight tank top that shows off her six-pack and well-muscled arms quite nicely, then follows it up with a pair of loose fitting sweatpants with an elastic waist. Your mind wanders, fantasizing about your aunt pulling those sweatpants down and just shoving her dick into you again and again, using your body.

By the time you shake yourself out of your daydreams and sexual stupor, your aunt has left, and you're not sure where she went, though you do catch the scent of toast wafting up from downstairs.
