Keeping up with the slow and steady fucking of the human girl, making it harder for her to cum just to show off at this point. Lightly purring to myself as well as I get into the thrusts in a smooth even manner, hearing her scream and struggle only making me smile. Looking over at her sister and giving her a wink as well, finally feeling the older cum against my cock. Giving her a spank as a reward,<strong>"Now now, that wasn't hard now was it?"</strong>Giving her one more good spank before thrusting in deep and cumming hard. Draining my SP into her and groaning out from the release, my cum filling her womb and transforming her into a flat chested kitten and being around 3 feet tall. Perfect standing height to suckle on a mans cock, as I pull out of her virgin pussy and give her new butt a spank.<br/><br/>Walking over to the remaining sister and stroking my cock at her, getting on top of the table where she is strapped down and rubbing my shaft against her virgin fuck hole. Teasing her with it and pinching a nipple,<strong>"Since your time as a sentient being is about to end, is there any last wishes you want...?"</strong>
