How about some good old fashioned lesbian sex. Finger her to get her good and wet, then eat her out. Give her an orgasm then the two of you trib for a good long while. Edge her and bring her close then rim her and eat her pussy until she can't take it anymore. Make sure it's on video and upload it with the title from above "Need to earn my place in the sorority".
Let us know how it goes.
Why stop at one of your sorority sisters? This is a big event in your life, so ask your Big to line up at least half a dozen of her sisters and have you eat all their c**ts and make them cum one after the other. Once that portion of your task is completed, they can give you and exceptionally long, thick dildo and have you fuck yourself with it while they make a commemorative video of the occasion for posterity. Of course, every on of your new "Sisters" should get a copy of the video, symbolizing your forever bond.
You need to please every woman in the house including the house mother. It’s your only option. Tell your sponsor you want them all.
