Lisa takes a special interest in the "Cavity" competition.

.."But that is tomorrow. As for the other competition, I will help you train for that. And that begins right now." -

Your mother stands up starts undressing and quickly removes every last item of clothing except her underwear. Through her black lace thong, specially designed for women, her half erect cock has already been leaking copious amounts of pre-cum. It seeped through her clothes and runs down her leg and drips out of the the laces on to the floor. She drops her underwear and starts stroking her steadily engorging monster to its full length. "I think this should be a good start for someone who intends to win the prize in the Cavity competition. From here we will work our way to bigger things. I have some toys we will use and I got a few friends who are much bigger than me, who would be delighted to help gape your hole to the necessary level, sweetie."

Your eyes are transfixed on the huge meat in front of you. About the length of Ashley's cock which just yesterday had been reaming and stretching your hole out, but quite a bit thicker. You've only just lost your virginity and then you decided to enter a competition where this is the beginner size? Just one dick in your ass and you have already lost all sensible thought. "Uhm, Mom I'm not su.." Lisa immediately interrupts you with a smile and a firm hand on your head. "Now now, no need to thank me. It's truly my pleasure to be a part of your journey to getting the sloppiest pussy in school. I always knew you had the talent for it!".

With ease, your naked mother lifts you up by the shoulders and flips you around on the bed. You flop on your stomach slightly harder than you expected as you feel your legs being pushed up and folded under you. You are now lying with your head on the bed and your ass raised up. The perfect position for your mother to take advantage of your exposed asshole. You realize your little prick is rock hard and throbbing. You turn your head so you can look behind you to see what is going on. Your mother is standing at the edge of the bed towering over you, her mouth slightly open and stroking herself with one hand and kneading your butt cheeks with the other. It seems with every stroke of her cock, a dollop of pre-cum is squeezed from her slit and she applies it expertly to her cock as to lube it up for your impending anal destruction. She catches your eye and gives you a big grin that doesn't nothing to hide how turned she is.

"Now, your girlfriend is also entering the competition and won't be able to fuck your ass enough to prepare you. But luckily for you, I can. I'm gonna bottom out in your little ass pussy, baby. Gonna make you gape so wide, there wont be any cock in the world you can't handle. And I am gonna dump so many loads in you tonight that you're gonna look pregnant." Another squirt of pre leaves the head of her crimson head cock. "But enough idle chatter. It's time we start taking this training seriously, Doug!"

Your mother gets up on the bed and stands behind your risen and exposed hole, with both of her legs on your side. You are sweating nervously. You are not sure you are ready for the strenuous training ahead, but at the same time you are so turned on just at the prospect of getting fucked by the huge tool that is right now hovering over your ass. You think to yourself; let's see how far we can go, why not?

Lisa starts gliding her cock between your cheeks smearing her pre-cum across your hole. You give a little yelp in surprise as you feel three of her fingers roughly inserted in to your anus. "Oh yeah, this hole has potential for sure. I can probably get my fist in there right away" your mother says with a giggle. It seemed like she liked her own idea, cause not a second after you feel her fingers leave you but instantly be reintroduced along with the rest of her hand. This time there is some resistance but her strong arms and her excessive spit and cockjuice slathered all over her hands and cock easily conquer your hole. A slight pop in your head and you feel your soon to be ruined boy pussy give way to Lisa's entire hand and she pushes down further to encompass her wrist. The initial pain gives way to that feeling of fullness that you have just now realized you are craving forever and always. You audibly moan and whimper as you feel the individual fingers in your ass wiggle and poke their way around as if to wave a hello to its new surroundings. You keep moaning and your small cock dribbles pre-cum on the bed as the sensations in your ass make you stop caring about the display you are putting on. "Fuck yeah, you are such a whore already, Dougie. I love it! I'm gonna be one of those coaches that love their job, I can tell you"

Lisa starts slowly thrusting her hand in and out of your asshole, leaving the fingers in and going down to her wrist in a steady rhythm. This goes on for a minute or so and then she starts taking the entire hand out and immediately push it in fast as deep as it has ever been, forcing your hole to stay open from the continuous onslaught. Every once in a while, your mother pokes that special place in your insides and it forces a tiny bit of cum out of your cock as well as a girlish whimper from your mouth. A final withdrawal and inspection from your mother proceeds. She dives down with mouth as she grabs both your cheeks and spreads your asshole wide and sticks her tongue inside. "mmhmm..gotta stick to the schedule and you are definitely ready for the next part of training"

She stands back up and mounts you once more, but this time no time is wasted as your gaped hole is immediately met by the pulsing and red hot head of your mother's fuckstick. Lisa pushes with some **** and your weak hole can offer no fight as you instantly swallow the first seven inches of her dick. The feeling is amazing. Any pain is immediately overtaken by the immense pleasure of fullness and of being stretched to new levels that you had never experienced before. From the first insertion alone you feel like you are almost cumming. Every membrane and muscle in your ass is on fire but in the best possible way. You are being owned by a massive cock and you are loving it. You utter through your shallowed breaths; "Oh boy, Mommy its so big".

"Thats right, baby and we are only just beginning. There will be no sweet overbearing mommy from now on and until the end of the competition. I am your coach and I will make sure this little stretched asshole here becomes the most stretched boy pussy I have ever seen. There will be no talking back, there will be no sick days. There will only be relentless asshole stretching, fucking and training. You got that, Doug? You got that, asswhore??"

Your mother's voice is ragged and filled with lust. She pulls out slightly until only the head remains inside your ass, plants a hard smack on your ass cheek, but then pushes harder than before and forces another few inches down your hole. This repeats accompanied by your involuntary lust filled moans and whines as her cock, wider than your arms, stretches your butt to new dimensions.

"And here..we..go!" Lisa pulls all the way out only to slam back down with reckless abandon. Her massive orange sized nuts filled with cum slam down on your taint and own tiny ballsack. Your eyes go wide and you can barely breathe as you feel your cock blast out squirt after squirt of cum. You are orgasming hard on your mother's huge cock. Your ass is involuntarily clenching down on the huge object inside it and it brings new levels of pleasure to you and to your mom "That's right, baby. I can feel you cumming with your ass pussy. You are gonna get many more of those and once you cant get any more and it feels like you are gonna explode, well then we are just gonna keep going until I'm done." She pulls out about halfway and sinks down hard balls deep back in your hole. It almost makes you cum again, but you realize you gotta train your own stamina if you want to survive your mother's training regiment. She laughs and commences the fucking in earnest. Her hands come down on your side and grab you just above your hips and she starts pushing in and out of your battered hole...
