“That makes three of us,” Daddy grinned, squeezing us both tight. “And speaking of things happening... your turn, babe?” he asked, rubbing himself against her hip.

“Good girl, sissy! I knew you had it in you! And now, you're about to really have it in you!” She laughed at her own joke, and started to push. True to her word, at least she went slow. I gasped and moaned, feeling the huge, hot weight of her gradually stretching me open, relentlessly forcing her way inside. She grabbed hold of me, one arm wrapping tightly around my leg, her other reaching around to grasp my dick. She wasn't stroking me anymore, not intentionally, but as she began slowly thrusting in and out of my ass, working her way deeper, the effect was the same. It took her maybe five minutes or so to finish getting all the way in, pressing hard against my ass, grinding to make sure I was feeling every last inch she had to give.

She lay there perfectly still for a long while, feeling her racing heartbeat against her fathers which steadily slowed with each passing breath. After what seemed like an hour, a muffled snore erupted from her father’s mouth and Sarah breathed a sigh of relief. She was dripping with sweat from the stress, but her pussy was even more wet. The entire time she had lain there, her father’s cock was filling her entirely, throbbing slowly, teasing her to the edge despite the fear. She barely dared to move as she knew that if she slid off his cock now, she would surely orgasm and collapse on top of him. And if that happened, he wasn’t going to sleep through that.
