Fuck me as hard as you can

The blonde woman, now inhabiting his father's consciousness, took a step closer to Jacob, her expression turning more serious. "Jacob, I have another favor to ask of you."

Jacob nodded, still somewhat in disbelief but willing to help. "Sure, Dad. What is it?"

His father, in the form of a stunning blonde woman, took a deep breath before continuing. "I need you to fuck me as hard as you can."

Jacob's eyes widened in surprise. He had not expected this request. "You want me to...fuck you?" he stammered, his mind racing.

"Yes," she replied firmly. "The machine has transformed me into this body, and I need to understand its capabilities. There are sensors and feedback mechanisms that will provide valuable data if we...explore this fully."

Jacob looked at her, taking in the striking features of the blonde woman who was now his father. He felt a mix of confusion, curiosity, and a growing arousal. "Okay," he said finally, his voice steady despite the whirlwind of emotions inside him. "If that's what you need."

She smiled, a hint of relief in her eyes. "Thank you, Jacob. Let's do this." She turned and walked towards the workbench, leaning over it and presenting herself to him.

Jacob approached cautiously, his heart pounding in his chest. He could see the curve of her hips, the smooth skin of her back, and the way her blonde hair cascaded down her shoulders. He reached out tentatively, placing a hand on her waist.

"Don't be shy," she urged him softly. "Give it your all."

Jacob took a deep breath and began to undress, his movements quick and efficient. He kicked off his shorts and boxers, his erection already straining against his clothing. As he stepped closer, he could feel the heat radiating from her body.

He entered her swiftly, a gasp escaping her lips as he filled her completely. Jacob started to move, his hips thrusting with growing intensity. The room filled with the sound of their bodies meeting, the workbench shaking slightly under the force of their encounter.

"Really hard," she urged him, her voice breathless. "Don't hold back."
