You have a dumbass idea. It's just so crazy that it might work.

You stare at the text box again while ****-doll continues to submissively suckle on your cock.

"Wait. 2/3..."

You came in her cunt the second time, but the progress bar shows a 2, not a 1 next to the number of times you came in her mouth. Technically she sucked the last bits of cum from your cock after you used her cunt, but that couldn't be it, right? That's be fucking stupid. That tiny little bit counts?

"Come here, you cock hungry slut. I want to see how wet you got while sucking my cock."

You push Alina's head down and stretch your arms out to grab her by her cunt, eliciting a deep moan from Alina as she continues to work on your cock. You shove two fingers into her sopping wet hole still dripping with your cum and pull Alina up by her hair, forcing her mouth open and wipe your cum on her tongue before shoving your cock back in her mouth.

"Guuuuuh! Mmmph!"
"Good slut, get back to it."

It worked. The number went to (3/3). Your cock twitches in excitement in Alina's mouth. That only left the first objective, but if your first **** of your sister was any indication, the moment of insertion was enough to complete the quest objective. All you had to do was fit your semi flaccid cock in her ass before your time ran out.
Without a second to lose, you pull Alina's mouth off your cock and flip her over on her side, and she goes over without resistance.

The fight apparently gone out of her after you used her cunt as a proper cum dump.

She rolls over weakly and moans as you get behind her, your semi-flaccid cock in your hands. You grip the base and drag it across her cunt dripping with your combined juices to get the head slimed up nice and proper, and start rubbing your cock on her puckered starfish.

"No.... no more..."
She whispers hoarsely as you start pushing your cockhead into her rectum.

"It's okay, slut. I'm not going to use you again, but I'll be damned if I don't end today's employee evaluation without sampling all three of your holes at least once. I'm just going to pop my cockhead in here just so I can say I did--- aah, there it is."

Your cockhead pops in without warning and you let out a quiet sigh of contentment as Alina moans quietly in protest. Victory.

[First quest objective completed. Second quest objective completed.]
[Quest complete. Reward for Completion: Psy Power level +1. Current Psy Power level: 2. ]
[Recruit familiar ability obtained]
[Will you designate a familiar at this time? Current pool of candidates: Alina Lopez, Vanessa Martinez]

Looks like you have two choices. If you pick Alina, you'll have someone who works at the Apartment complex already and will be able to help you complete the rest of the main quest faster, and she might be able to tell you more about what exactly you inherited here at BJ Towers. And it'll neatly fix the current problem you have, you're sitting in a bathroom with a girl you just **** who managed to best you in a fight twice already, and you don't have any rewind powers to stop a third attempt from succeeding. She looks pretty docile now, with your cockhead shoved in her ass, but you're really not sure if that's going to last or not.

Your second choice is your little sister. Who IS the smartest person you know, and you're pretty sure she can help you figure out some genius ways to get in these girl's pants were she inclined to do so, and she probably will be if the submissive score works the way you think it will. That and picking her will immediately complete the tutorial quest, which will mean that you get those rewards too.

But is completing the quest right now a good thing? What if the reason they gave you a month for the second tutorial quest is because you were actually supposed to take that time to train and learn more about your powers? After all, this quest was damn near impossible to beat and this was with the difficulty being adjusted down. You almost failed it and would have if you didn't figure out that any trace amount of cum works, and it can even be from the same orgasm. You're not sure you'll get this lucky again, having training wheels might not be a bad thing right now.

Oh, looks like you still had a tiny bit of cum left in your balls. You push your semi-hard cock deeper in Alina's bowels and she gasps from the intrusion. You release one final spurt of cum deep in her guts, and use the lubrication to slide your cock in deeper, her degradation complete.

But really, who should you pick?
