Yes, Obviously

For a brief moment, I hesitate. It occurs to me that I may be doing the wrong thing by selecting Riley as a target. However, those hesitations are short-lived as remember my vision of my younger sister on her knees. Despite being in college, I still live at home and I don't think I can tolerate living in the same house as her if I can't have her. Swallowing my nerves, I hit accept.

Name: Riley

Surname : Blackwell

Gender: Female

Age : 18

Relation : Sister

Level 1 (0 / 10 xp)

Class: None

Perks : None

due to lack of options, I select Quest Designer I. It's nearly 11pm, significantly later than I thought. The good news, however, is that I can tell Riley is still awake, meaning that I can hopefully have Riley complete a quest before she goes to sleep. This quest is going to require a careful amount of finesse. I want it to be somewhat sexual, or at least lead to something more sexual in the future, but I don't want it to scare her too much. I want to find the perfect balance.

Suddenly, I have an epiphany. I partly close my bedroom door so it's just barely open. Then I take off all my clothes save for my boxers, which I keep around my ankles. Eager to enact my plan, I enter the quest "Look Inside Dominic's bedroom". My phone then displays the message "Quest Accepted. Selecting Appropriate Reward. Reward: Increased Comfort around Dominic". I'm thrilled about this reward, practically the best-case scenario. Not only will Riley see me naked and be more comfortable through repeated exposure, but the comfort will be further amplified by the app's own reward.

For the next 10 minutes, I stand naked in my room, pretending to get dressed. I feel stupid but I feel confident Riley will take the bait eventually. She's always been somewhat mischievous and happy to get into your personal space. Suddenly, I begin to hear footsteps and I smile as I know my effort wasn't in vain.

"Oh My god I'm so sorry" Riley cries as she opens my door.

"It's ok Riley, I trust you enough to not doubt your motivations" I respond trying my best to de-emphasize the taboo nature of the incident without causing suspicion.

Riley blushed. "Thanks, she muttered." She then closed my bedroom door and left.

The moment she leaves, I excitedly check my phone. Sure enough I see the following messages:

"Riley Blackwell has completed her quest. [+5xp]"

"Baby Steps: Successfully assign one quest. [+5xp. ]

"Achievements unlocked"

Level Up [ +1 Perk Point]

Newfound Purpose: Unlock Achievements [+ 10 xp]

Level Up [+ 1 Perk Point]

Excellent news, I now have two perk points I can play with. I don't even bother browsing, I know immediately how I spend them. Immediately, I go to the perks menu and select "Class Designer".

Class Designer: Give a class to a target, slowly altering them as they level up.

Now I had the option to select a class for Riley. Looking through the options of classes, I found an overwhelming number of options. Interestingly, nearly all of them were in some way sexual, supporting my theory that QuestMaster intentionally wants its users to be corrupted. I couldn't make Riley an accountant, but I could choose between 12 different varieties of masochist.

Going through the list of classes, I had some vague ideas about what I did and did not want. First of all, I don't want to pick any class that would result in her suffering or being genuinely afraid of me, such as **** victim. In spite of everything, I'm not a complete monster. Similarly, I don't want her personality to completely change. That being said, I want to choose a class that will make it easier to get more sexual with her.

I search that list for over an hour, eliminating classes and considering the remaining candidates. All the while, lewd images of Riley play continuously in my brain. I saw Daddy's girl Riley, cheerleader Riley, a collared Riley begging her Master to let her cum, and cuckquean Riley enviously watching me fuck her friends. Eventually, I found the perfect role for my younger sister. Confident that I wouldn't make a better decision, I confidently selected...
