Katharine's answer to his question was a source of pleasure in of itself and only hastened his ascent to the peak of his orgasm.  While he wouldn't have hesitated to follow her wishes if she said otherwise, he was elated to hear that his daughter would accept his seed.  In his mind, it was the most intimate of endings to the most intimate of acts.  The wanting expression in her eyes shown clearly how she genuinely wanted it.  As he continued, his rhythm became more sporadic as waves of intense pleasure pounded through his nerves, sending them alight with building ecstasy.  Jacob with each thrust he could feel himself inching closer and closer  to his climax, while still doing all he could to keep a steady slower pace so he could thoroughly savor every moment of the feeling.  It wasn't long before he found himself on the precipice of release and instinctively wrapped his arms around his daughter, pulling himself into a tight embrace that was intensified by his orgasm.  Just before the pleasure stole his breath away entirely, he whispered passionately into her ear.  "I love you, Katharine."<br/><br/>With that Jacob's entire body seized up as his climax hit him full force.  A long, basso moan resonated from his throat as he rode those sensations for what felt like a blissful eternity that was all too short.  His thrusts slowed, but never stopped or lost the force behind them.  Then one last time he buried himself to the hilt into his daughter, penetrating her with as much of his length as he possibly could  just as he took in a deep breath as all the tension in his body released and his cock began pumping his hot cum deep inside her womb.  There would be no risk of impregnation, so the two would be able to completely enjoy the feeling without having to worry about any undesired outcomes.
