From the looks of it, your sister’s handjob had given her enough time to make it to level 2. Plus from the fact that the achievements had only given you 2 points, made you suspect that there was something special attached to them. As much as you wanted to go through them all in detail, you had a schedule set up that you were trying to loosely follow. You gave all the information a quick glance. First achievements and then the best saved for last, Sarah’s status.

More and more surprises seemed to keep popping up and you weren't gonna complain about your newfound series of luck. This also put you just 2XP away from getting your level to 4 so it was only a matter of time before you unlocked the last menu item.

After quickly cleaning up the cum that hadn’t landed on your sister or her panties, you threw some boxers back on and finally got out of bed. You decided to go and have a shower before tackling the remaining family member who had been hesitant to speak with you.

For now, you balled up the now cum stained panties and walked down the hallway before dropping the underwear off in Sarah’s laundry basket. Luckily for you, we all had separate baskets for our own washing due to Mom thinking it would make us more ‘independent’ so it put a smile on your face knowing Sarah would be dealing with the results from your session with her earlier.

While in the shower you felt you had some time to contemplate the new additions that you had now gained. The second user upgrade would always come in handy but it would probably be better to activate it at once you had more time after school later. You also didn't want to admit you were hesitant to use it after the pain you went through last time.

You didn't really have a use for the ‘Absolute Zero’ cooldown now that your sister was presumably still sans underwear, but you were already thinking of ways it could be useful in the future. Plus now that you had Sarah at level 2 it gave you another option to use it on.

You were a bit disappointed you had to wait for those effects to be usable, as you wouldn't mind having Sarah join you right about now but at least it gave you one more thing to add to tomorrow's to-do list. Both the passive and the active effect seemed pretty self-explanatory but you would be more than happy testing them out when you got the chance. The jump to reach Sarah’s level 3 seemed a lot bigger in comparison to 2 so those chances better be as often as you could manage.

A finished shower and a clean-up later and you were done in only 20 minutes. You wrapped yourself in a towel as you made it back to your room and sat on the edge of your bed.

You were surprised to find that you were already getting hard thinking about your next moves with Mom. That upgrade was already putting in the effort, especially considering how big of a load you shot into Sarah’s underwear earlier.
