Jack came home and found that Sophie had something in mind. They'd managed to tie their hands tightly to one of the straps we kept permanently attached to the bed frame. Their long arms stretched out in front of them with their back rising up to meet their ass, their feet firmly planted on the floor. Their thick thighs were just waiting to be parted. Next to them was Jack's favorite belt. It was too wide to wear as a belt, but as a sex toy it was just perfect.
Jack walked around to the other side of the bed and looked deep into Sophie's eyes. They were already deep in their head, so turned on their skin was blushing from the top of their head all the way down their back. Normally when they were like this, Jack would make them undress him, but with their hands tied, that wasn't much of an option.
He lifted his foot on to the bed and placed his right shoe directly in front of Sophie's mouth.
"Untie my shoes beautiful."
They reached out and grabbed the end of one of the laces with their teeth and pulled until the knot came undone. Jack made them do the same with the other shoe. Sophie tried to use their teeth to pull down his socks, but the angles weren't working out to well.
Jack laughed and pulled his socks down. He placed both feet around their head. Sophie immediately started licking his soles. Jack didn't particularly have a foot fetish, but he knew Sophie loved it, and he would never deny them pleasure, except those times when that was the point of the game.
Sophie started sucking on his toes, trying to cram as many as they could into their mouth at once. It almost made him cum on the spot.
"Down little one, I need to finish getting undressed."
Sophie pouted just for a moment and then started smiling as they saw Jack's body being revealed. They loved nothing more than to turn on their man, and judging from how swollen his cock was, Jack was more than turned on.
Jack leaned down and shoved his tongue into Sophie's mouth and tasting them for the first time that evening. He pulled back just a little, grabbing their lower lip between his teeth, and he bit down, just hard enough to taste their blood. He pulled back and looked at them
"Do you want this little one? Are you sure babygirl? Last time we played this game you were black and blue for almost two weeks."
"Yes Daddy, I need it."
"I love you baby. You tell me to stop if you need me to. Use your safe word and I'll stop immediately and take care of you."
"You know I've never used my safe word with you Daddy. And I never will with you. I trust you in ways I still don't fully understand."
Jack kissed Sophie deep on on the lips.
"I love you too baby girl."
