Onyx was supposed to take little step-sister Sushii out for a shopping date, but she can’t seem to peel herself away from her video call with her boyfriend. Sushii begs Onyx to please hang up and pay attention to her, because Onyx promised they would have a fun day together shopping! Onyx can’t be bothered and rolls her eyes at her annoying little step-sister’s attempts to grab her attention. Sushii becomes increasingly more frustrated as Onyx continues to ignore her. Fed up, Sushii reaches into Onyx’s white jean shorts, grabs her PANTIES and WEDGIES her!! Onyx is shocked and quickly hangs up the phone before jumping up to confront her annoying little brat of a step-sister! “Did you seriously just wedgie me in front of my boyfriend!?” Onyx has had enough and throws Sushii down before giving her a taste of her own medicine. Onyx YANKS Sushii’s PANTIES HARD and WEDGIES Sushii as she cries out in pain! “OWWWW! STOP!” But Onyx has only gotten started. She can’t believe her younger step-sister’s audacity to PULL HER PANTIES while she was video calling her man! Onyx is fuming and doesn’t plan to let up on the wedgies any time soon. Onyx WEDGIES Sushii with merciless FRONT and BACK WEDGIES, pulling Sushii’s undies tight against her ass! Sushii wails in pain as she threatens to tell on Onyx, but Onyx is far beyond caring at this point. As Onyx continues to wedgies Sushii she realizes that Sushii is wearing Onyx’s shorts!?!? Onyx rips her shorts off of Sushii and continues her revenge wedgie tirade! She stuffs Sushii’s arms into the waistband of her undies and hikes them high up to her shoulders to create a humiliating wedgie onesie! Onyx still doesn’t think that Sushii has had enough, so she goes in for the ATOMIC WEDGIE! She pulls the spandex tightly over Sushii’s face until Sushii is practically eating her own waistband. Since Sushii humiliated Onyx by wedgie-ing her on video chat, Onyx thinks it’s only fair that she take some photographic evidence to send to Sushii's crush and later blackmail Sushii with! Sushii tries desperately to cover her face in embarrassment, but it’s too late! Onyx has taken some of the most humiliating photos EVER, that will surely come in handy in the future. Satisfied, Onyx leaves her little step-sister Sushii stuck in an atomic wedgie, for her to figure out how to escape her wedgie predicament.
