Trying out your other end

Alexandra starts lifting your ruined body off of her dick until she finally pops out her swollen tip. Her thick sperm starts leaking out of your ass, covering her own dick in cum. Your stomach starts going back to its flat state as more and more of Alexandra's spunk exits your anus. She brings you up so that your face is in level with hers.

She speaks up "Well, now that I've dominated one of your holes, let's move on to the next one, shall we?"

Alexandra flips you upside down. All of the cum in your stomach shifts around as gravity starts pulling it down toward your mouth. Luckily, your stomach manages to keep it inside itself and keeps you from throwing up jizz. Alexandra's cock is pointed straight up, right below your mouth. You're still facing her, and she's holding you by your ankles, slowly lowering you down on her shaft. You watch it come closer and closer to your face and your anxiety starts to grow. However, she stops lowering you when only an inch wide space is left between your lips and her cock head.

She says "Now, I'm gonna keep lowering you down until your chin touches my ballsack. If I hear you make ANY sound, I'm going to destroy your throat and pump you so full of cum that you pop like a balloon. No pressure!"

She ends with a sarcastically happy tone.

You open your mouth as wide as you possibly can and Alexandra continues lowering you down onto her cock. Once your lips close around her pre-cum covered tip, you realize there is no going back. You can feel her cock reach the back of your throat in no time at all, but you manage to hold back your gag reflex for now. Your body weight is enough to **** her giant shaft deeper and deeper down your gullet. Once 10 inches of her dick meat is down your mouth, you simply can't hold back. You cough around her cock loudly, spraying spit from your mouth and nose. A split second later, Alexandra practically lets go of your legs, making her dick impale your throat. Your gagging becomes louder, but then it stops completely, as your airway gets blocked by Alexandra's cock. She grabs onto your torso and forces you a few more inches down until you can feel her balls graze your chin.

Her giant penis throbs inside your throat, and you feel every bit of it.

Alexandra looks down at you and says "Hey, I warned you. I didn't think you were THAT much of a wimp, but geez... Oh and don't worry, I'll keep my end of the promise."

You understand your place and accept the consequences without struggling. She tightens her grip around your torso and lifts you back up, off of her dick. You manage to get a quick breath before being slammed back down her shaft. You feel slight pleasure as her cock finds it's way back up your throat and you start getting hard just from the feeling of being dominated by this giant beauty. Alexandra starts slamming her 2-foot cock in and out of your throat with ever growing speed and ****. Soon enough, her spit covered balls start slapping against your chin and you inhale her dick with each thrust.

As she keeps clogging your throat with her dick, you get fewer and fewer opportunities to breathe, and your vision starts going dim. You don't care one bit. Being a fuckable toy is your only true purpose, and you'll fulfill it to the best of your ability. You just relax your body and let Alexandra use your throat all she wants.

After an unknown amount of time, Alexandra starts moaning and slamming her cock in your throat even faster and harder. You feel it pulsing and stretching at the walls of your esophagus and you feel like her orgasm is near. She slams you down one last time, burying your face in her dick and holding you there with her strength. You feel the cock in your mouth contort and twitch as her cumshot travels through it. Then, you get a full frontal blast of cum straight down your throat. It shoots directly down your stomach, mixing with the leftover cum from her last orgasm. You don't even get a chance to taste it. From the first load alone, your stomach is already back to being fully inflated to its limits.

The second load exits her cock and her cum starts dripping from your mouth and nose, barely slipping past the enormous shaft blocking your throat. As the next load comes, all the cum starts straight up shooting out of your nose and mouth. Your eyes go wide as you feel the amount of cum entering and leaving your body with surprising pressure. Your stomach somehow still keeps inflating, until it's as big as the rest of your body. Being **** fed cum gets you extremely horny and you blow your load all over Alexandra's toned belly.

You keep getting filling after filling of sweet and thick cum until Alexandra finally seems to start running dry. You can feel her cock shrink inside your throat and her loads start becoming smaller. Once she grunts and pushes out her last loads, she lets go of you and your body just falls off of her limp dick. You fall to the floor and try inhaling some air, but the sheer amount of cum in and around your mouth is blocking your airways, so you start swallowing. Alexandra's cum tastes very strong, and you enjoy every bit of it. Once your mouth is clear of cum you start breathing normally. You then take a look at your stomach and realize that you can't even see your legs over it. Your stretched asshole leaks sperm profusely and slowly starts draining your stomach.

You hear Alexandra snoring behind you, so she must have fallen asleep. You realize that that's not such a bad idea and do so as well. You wake up a while later and see that Alexandra is no longer in the room.

The intercom turns on Alan speaks to you. "Well well well, if it isn't our balloon boy. Sometimes I'm honestly surprised by the limits of your body, but I guess that's why you're our best test dummy. Anyway, Alexandra's back in her room and you should be too. Science never rests!"

As the intercom shuts off, you pick up your ruined body and limp over to your room, spending a good 30 minutes in the shower washing yourself off.

You got the "Simply stuffed" ending with Alexandra.
