A measurement app

You are John Ring, a college student commuting to school, living with your two step-sisters, Emma and Sophia, as well as your mother, Avery.

The app has a ruler symbol on it, and you open it to see a blank screen with a white cutout of a woman's body on it, in a sort of T-pose position. You notice there are icons at the bottom of the screen, but the shop-looking icon is locked off, and you can't access it. There is, however, a camera icon that just opens your back camera.

Confused, you try tapping on the different parts of the body outline, but nothing happens. Suddenly, a notification pops up on your phone screen with a message that reads, "Unlock the full potential of the app by completing daily challenges." Intrigued, you decide to explore further and see what these challenges entail. After closing the notification, you are redirected to a screen that reads "Tutorial." Beneath it is a quest, "Capture your first subject." You realize that the camera option is what you will need to use.

However, your thoughts are interrupted by your mother calling you down for breakfast.

You head downstairs to the smell of bacon and eggs, seeing that Emma and Sophia are already at the table. Emma is your older sister; she is well-endowed in the chest, has large breasts, and is thick overall. You estimate that she is about 5'5". Sophia is almost the opposite, having a very thick lower half, with her thighs and ass being where most of her weight is carried. Her breasts are also smaller, and you estimate that they're around a B cup. She is shorter than Emma, standing at around 5'2".

As you sit down to eat, you can't help but wonder how you will capture your first subject for the quest later in the day. Sophia looks up from her phone and greets you, but Emma doesn't even acknowledge your presence whatsoever. As you finish your breakfast, your mind drifts back to the measurement app, and you decide to pull your phone out, determined to discreetly capture Sophia's measurements while she's distracted. You make a mental note to approach Emma later, when she's in a better mood. As soon as Sophia is in the frame of the camera, the app automatically takes a picture, and it redirects you to the main page, which now shows Sophia instead of the blank outline. A number in the corner goes from 2 to 1, which you assume must mean you can only snap up 2 new girls per day.

There are exclamation marks around her various body parts, and another notification appears, showing you've completed the tutorial and blessing you with 50 "reality tokens." You close your phone after seeing the time and realizing that you need to get ready or you're going to be late.

As you finish your breakfast, you get ready and call Sophia down to head to the car as you hop into the driver seat. She comes down and gets in on the passenger side, and you both drive to school. Once you arrive at school, Sophia waves goodbye, and you part ways as you head to your own classes. The notification about the reality coins lingers in your mind, tempting you to explore the new virtual world further when you have some free time.

You walk into your first class, English, with the bombshell of a woman, Professor Kay Smith. Well endowed on all fronts with huge tits, rivaling even Emma's size. Her ass is big too, with wide hips to match. She is even slim despite this and has a commanding presence that demands attention from all her students.

As she begins the lesson, you can't help but feel a mix of intimidation and fascination with Professor Kay. She is wearing a tight-fitting pencil skirt that accentuates her curves, and her confident demeanor only adds to her allure.

Professor Kay isn't the only one in the class who stands out to you, however. There is the quiet girl, Mya, who is much less endowed than the professor, having virtually no breast size to speak of and very few curves. Despite her unassuming appearance, Mya's sharp intellect and insightful comments during class discussions always leave a lasting impression on you.

You decide you should get a snap of one of them too, trying to decide who to get first today.
