Give Juliet a reach around

As you continue thrusting Juliet's tight ass, she moans louder and louder. You can feel yourself getting closer and closer to orgasm. While resuming your relentless thrusting, you lean forward and use your right hand to grab a hold of Juliet's cock. The angle you're at makes your thrusts shorter but a lot faster.

You're surprised on how hot and throbbing her cock feels in your hand, she must really be ready for release. Your hand moves over to her tip, making Juliet moan louder than before.

"Stroke my cock, Master!" she screams out in pleasure.

You wet your hand with the pre-cum coating her tip and start stroking her dick in rhythm with your humping.

You lean in even closer, your chest now right against her back and use your other hand to stroke her cock as well. You speed up your thrusting, making you go off like a jackhammer. You feel the cum churning in your balls and you prep for orgasm. Juliet's cock also starts throbbing and her breathing picks up.

Finally, you thrust into her, balls deep with a loud smack and unload your stored up cum in her ass. It feels like her ass is sucking out every drop of cum in you, and all you can do is lay on her back motionless and moan. At the same time, you pull back on Juliet's throbbing cock and feel it twitch, as a giant stream of jizz gets shot at the ground. Her stream is so powerful, that the jizz lands a couple of feet away from you two. Juliet screams in ecstasy as she shoots load after load from her throbbing cock. You continue unloading your own cum in her ass until you are cleaned dry. The orgasm you just experienced leaves you speechless and static.

You feel Juliet's knees start to shake and her legs give out, making her plop down on the floor and you on top of her. Your hands still haven't let go of her cock, so they get stuck between it and the floor. You feel her pump out a couple final spurts of cum when finally it seems that you are both done.

The room is filled with a moment of silence and all that can be heard is loud breathing from both of you.

Juliet speaks up with a tired voice "Thank you, Master. I hope that my ass made you happy."

You respond "It sure did Juliet, it sure did..."

You both take a minute to rest after the fuck session. You are first to get up, pulling your hands from under Juliet and slowly standing up. Your, now slightly limp, cock slides out of Juliet's ass, revealing a bright red hole with a white center. Your cum slowly leaks out of her ass, leaving a white trail moving down her leg. Juliet brings herself to her knees and looks very calmly at you, her cock resting on her thigh, covered in her own cum.

She takes a moment to fix her hair how it was before and says to you, smiling: "Thank you again, Master, I hope this experience was as good for you as it was for me! I believe the test is over, so you may head back to your room!"

You wave goodbye to Juliet and return to your room, stepping over the puddle of cum she left on the floor. Your knees feel a bit weak from your powerful orgasm, so you lie down in bed and rest for a while.

You got the "Happy doggy" ending with Juliet.
