Spy on their date tonight

Jenny spent the next several hours looking through the Master PC settings and help files to get a better understanding of how the program worked. She was just finishing up some adjustments to her friends and family that would improve their health when the doorbell rang.

It was Saturday evening so that was almost certainly Keith arriving for date night with Grace. Jenny decided to use a new Master PC function she had discovered to spy on their date and see how her changes worked out.

Grace answered the door wearing a navy blue halter dress that only came down to mid thigh and a matching pair of blue heels. She greeted Keith with a kiss and invited him in. Keith was a tall, athletic white guy with blonde hair. Jenny preferred girls but she had to admit Keith was a handsome man.

"Are you wearing what I asked?" Keith asked Grace with a devious smile.

Grace blushed, turned around and lifted up the back of her dress to reveal that she wasn't wearing any panties and had a butt plug nestled between her cheeks.

"Good girl," Keith said with a smile as he gave Grace a playful swat on the butt.

The couple left the house and got into Keith's car to head to a nearby restaurant for dinner. On the trip Keith had Grace pull down the top of her dress so that anyone lucky enough to look into the car got an unobstructed view of the Asian girl's perky breasts.

Before entering the restaurant Keith gave Grace a remote controlled vibrating egg to slide into her pussy. Through out their meal Keith teased Grace with the vibrator. When the waitress brought them their check Keith turned the vibrator up to max speed and Grace did her best to hide her orgasm.

Jenny was surprised by how hot it was watching her sister have an orgasm in the middle of a crowded restaurant.

When they got back to the car Keith had Grace remove the vibrator and lick it clean before they made their way back to the Nguyen house.

Upon arriving home the couple quickly made their way to Grace's room and locked the door.

"You were very sexy tonight," Keith told Grace.

"Thank you, sir."

"You got me really hot," Keith smirked as he undid his fly and let out his 9" cock, "Now it's time to take care of this. On your knees, pet."

Grace happily did as she was told and took her boyfriend's big dick into her mouth and started bobbing her head up and down on it. Keith was incredibly turned on by their date and it wasn't long before his orgasm was building.

"I want to cum on face, pet."

Grace pulled her lips off her boyfriend's cock and pointed it towards her face.

"Cum on my face," she said as she jacked the big cock in front of her face, "Coat my glasses with your sweet cum."

It was only a couple of moments before Keith did just that. He shot rope after rope of cum across Graces face and glasses.

"Mmm, you look so sexy with my cum all over his face," he told his girlfriend.

"Thank you, sir," Grace replied with a proud smile.

Even though he just came his cock was still hard.

"You've been such a good girl," Keith told Grace as he guided her over to her bed, "It's time for your reward."

He bent her over the bed and pulled the butt plug out of the Asian girl's ass. The plug was quickly replaced by Keith's cock.

"Oh fuck! Thank you sir!" Grace moaned, "You know how much I love having your big cock up my ass!"

Jenny sat in her chair, watching the scene unfold on her monitor. Her panties had long since been discarded and her legs were spread wide on her desk. One hand rubbed her clit while the other fondled her big boobs.

Jenny couldn't believe how turned on she got watching her sister and her boyfriend fuck.
