"Rach? You there?"

The two sisters' eyes widened at the sound of Emily knocking on the door. Thank God, Rachel locked it. She didn't want Emily to walk in and see Rachel on top of Victoria, the older sister's hands tied and a black dildo down her throat.

Victoria had been focused on taking the toy when she heard Emily's voice. She glanced towards the door and seemed to consider screaming through the dildo to let her know that she needed help. But Rachel had other plans.

The youngest sister grabbed the base of the dildo and gave it a hard push forward. Inch by inch, the thing went deep into Victoria's throat, causing it to bulge a little as the base reached her lips. She looked into Victoria's eyes with a serious, threatening look as she responded calmly. "Yes, Em? I'm a bit busy right now."

Victoria was **** to breathe through her nose, trying not to **** on the dildo. Her eyes rolled back slowly, trying to stay awake and focus on the conversation.

"Well, if you feel bad about what happened, don't... I... I kind of liked it..."

Victoria had no idea what she was talking about but she couldn't really think about it right now. She could feel her conscious fading.

Rachel just smiled and caressed Victoria's cheek. "Still... I feel like I **** you... I just want to be alone right now... if you don't mind..."

Emily was quiet for a moment and Rachel thought she had left. She was about to pull the gag out when she heard her oldest sister speak again.

"Rach, if you ever need anything... please, talk to me... I'll help you with anything... you know that, right?"

Rachel bit her lip, watching Victoria get closer and closer to passing out. She could feel her erect cock pressing against Victoria's stomach, throbbing in her shorts. "I know, Em... I appreciate it... I love you."

"I love you, too, sis." With that, Emily could be heard walking back down the hall and heading downstairs. After a couple seconds, Rachel finally pulled the dildo out and let Victoria take a big breath of air.

Victoria coughed heavily, finally able to breathe properly. It was a struggle to do with the dildo down her throat and she was barely getting enough air. She focused her eyes on Rachel, who grinned, looking at the dildo. "You did pretty good, Tori... I'll let you go now... oh, and I shouldn't have to say this but if you say anything about what happened, I'll destroy you..."

Victoria was still dizzy but nodded slowly as Rachel untied her wrists. As soon as Rachel got off of her, Victoria stumbled up onto her feet and slowly made her way towards her room.
