With a cold smile, Oni steps forward and roughly grabs her boyfriend by the hair, pulling his head back to look at him. "You are such a pretty little thing," Oni says, running a finger down his cheek. "And now you belong to me." With that, Oni pushes her boyfriend to the ground and straddles him, grabbing his wrists above his head. "Becky," he growls, "get on your knees beside him and watch as I take what's mine."

Becky's heart races as she obediently drops to her knees beside her boyfriend, tears streaming down her face. She can feel the heat of Oni's body against hers, and it only serves to make her wetter. With a shuddering breath, she watches as Oni positions himself behind her friend, pushing his hard length inside in one forceful thrust.

Carl shakes violently, struggling to maintain his composure as he tries to think of a way out of this impossible situation. He looks over at Heat Week- Becky's Service pleadingly, wishing there was some way for her to understand what she's done. But it's clear that she is no longer the same girl he once knew; she has been transformed by heat week into someone completely different... and now his sister may be next.

You take this opportunity to push yourself deeper into Heat Week- Becky's Service , using her body as leverage to drive yourself closer to the edge. Carl watches helplessly, tears streaming down his face as he listens to the wet slapping sounds of your hips against hers.

"Please," he whispers desperately, "please don't make me do this." But it falls on deaf ears; all that matters now is fulfilling your twisted desires.

Becky's heart is pounding in her chest as she listens to Emily's reply, trying to ignore the strange feeling of being used by both you and her sister. She relays the information about where and when to meet, then hangs up the phone with a sigh.

"Okay," she says quietly. "Emily will be there." Her eyes meet yours, and for a moment, she wishes things could go back to how they were before you took her collar in exchange for your promises of protection and pleasure.

Becky blushes at the praise, looking away shyly. "Th-thank you," she stammers. The idea of a reward makes her heart race with anticipation; what could Oni possibly have in store for her this time?

You smile warmly down at her and lead her out of the kitchen, towards your room. "Come here, pet," you say as you enter the dimly lit space. "I think it's time for your reward."
