You, as an obedient sissy girl, will carry out the orders of Mistress Sylvia...

You stand there and blush a little with shame...

Sylvia annoyedly tells you, "Hurry up, you stupid sissy whore! I need to check the quality of the product and I need to make a promotional video for my privileged clients! So carry out my order immediately! Plus, the test procedure of these ten big dildos will have a beneficial effect on your sissy anus. Your sissy hole will become even more elastic, tender, softer and more pliable..."

You timidly walk towards the bed. You sit on the bed so that your round butt hangs slightly off the bed. You lower your miniskirt and your panties...

You lubricate your tender anus with lubricant...

Your little white dick gets a little excited... But your little dick can't get hard because of the miniature metal chastity cage...

You take a large black dildo from the table which measures 18 centimeters... You lubricate the tip of the dildo... You slowly bring the head of this large black dildo closer to your sphincter... Your sphincter is pulsating in anticipation of the anal "adventures" awaiting you.. .

You feel intense pleasure when the head of the big black dildo overcomes the resistance of your sphincter and enters the depths of your anus...

You let out a feminine moan: “OOO..yess....ahhh......what a big... big... black dildo... ahhh...”

You hear Sylvia laughing as she continues to film your actions on her smartphone.

You keep fucking your own anus with this big black dildo...

From pleasure you arched your back and you began to wave your ass a little...

Your small white cock, which is locked in a miniature metal chastity cage, is now erect and leaking clear liquid.

You moan and make quiet feminine sounds: “Ahhh... I need... a big black dildo... in my anus... oohhh... what a pleasure... ahhh...”

Your stretched, soft, pink anus enjoys being penetrated by this big black dildo...

Suddenly, with a quick movement, you push all 18 centimeters of this big black dildo into the depths of your gaping anus...

You feel a slight discomfort that quickly disappears...

Then you experience a sudden surge of pleasure. This movement, which allowed you to push the large black dildo almost all the way into your anus, sends shivers down your spine and sends waves of ecstasy throughout your body.

You push the full length of this big black dildo into your sissy anal hole again and again...

You realize that you have pushed all 18 centimeters of this big black dildo into the depths of your tender pink anus. The rubber balls of this big black dildo slap your ass over and over again...

You reach anal orgasm.

You twitch, your legs tremble. Your small white cock, which is locked in a miniature metal chastity cage, squirts a small amount of your puny transparent cum. As the series of waves of exquisite pleasure subside, you feel the clear liquid (your pathetic sissy cum) smeared on your soft belly skin.

You continue to sit on the bed. Your legs are up. Your anus is now visible to Sylvia, who continues to film you with her smartphone. Your transparent sissy cum is slowly dripping from your hairless soft belly. Also, droplets of your clear sissy cum are slowly dripping from your little white cock, which is locked in a miniature metal chastity cage.

You realize that now all 18 centimeters of this big black dildo are in the depths of your stretched, gaping sissy anus. The rubber balls of this big black dildo are now in tight contact with your ass.

Sylvia tells you in a pleased tone: "Nice show you put on now, Mary! This would make a great promotional video for my privileged clients! So, now you have 9 more big dildos left! Keep going, sissy bitch! Hurry up!"

Over the next two hours you are **** to try 9 more large rubber dildos on your anus...

You've lost track of time...

You experience one anal orgasm after another...

One dildo... Then another dildo... After that, the next dildo... Wow! Dildo measuring 25 centimeters! You should try this dildo too....

Your mind is poorly aware of what is happening due to a series of anal orgasms...

During this entire anal "marathon" Sylvia films your actions on her smartphone...

Sometimes she accompanies your actions with mocking, derogatory comments for you...

But you are unable to object... You are concentrated only on the sensations of your gaping anus...

Finally you finish checking the last dildo...

You see that your pink anus now looks like a large, stretched, gaping, inflamed hole...

Because of these dildos, your anus is now greatly dilated and your anus cannot close...

You hear Sylvia's mocking voice: "Great job, Mary! I've made a lot of quality promotional videos for my privileged clients! I'm sure they'll love your cute look as a slutty sissy whore who loves to fuck her own anus with big dildos! Also, I'm glad to note that the current sight of your stretched, gaping sissy anus is a good confirmation of your status as a pathetic sissy bitch who can only orgasm if someone fucks her anal sissy pussy with something huge!”

After these words, Sylvia ordered you to get ready as it was already evening time. The store will be closing soon. You got out of bed and cleaned yourself up. It wasn't easy. Your legs were still shaking, your anus was itching. Your butt plug in your anus now felt a little different due to the fact that your anus is now much more stretched...

You thought: "I'll probably need a bigger butt plug soon..."

You have listened to Sylvia's orders regarding tomorrow. Sylvia then went to her home and locked you in the store.

You got ready for bed. You lay down in your bed.
