Now just the two in the room, Hanna would be the older and more domant woman right now, as the spirit leading and coaxing her would entice her to do what ever her body could endure to get her brother's arousal, and morning wood to give in and grant a quickie so to speak.
as the voice in her mind told her how good it would feel, how rewarding to make her brother her man, and how she could use and enjoy him, as he would be loyal to her only. painting a lewd, incestual picture of passion, and love in a mind which would normally never even consider such a thing. However in Horus's mind, a gentle and feminent voice would speak to him as this went on. now asking if he would indulge this woman, perhaps give her a show, and some ideas of how they could have fun later as well? however unlike the spirit manipulating Hanna, the one in horus would come off more excited, and wanting to see tricks she could try on her living partner later.
as this went on, the brother who was now washing up would soon feel something unexpected, but enjoyable. while washing up and preparing to head down for breakfast, it would soon feel as if his cock was in the mouth of some one, despite no one being their. this would reveal how his spiritual playmate was excited, and far more aroused then expected. enjoying him, as the spirit would seem to be out to quickly milk the young stud, and absorb his seed. as it would vanish the instant it came out of him. being turned into an energy source for her. As if this would be like a binding reason for them to enjoy one another. the more she could absorb the more she could manipulate, and enjoy physical worlds, having absorbed some of his life force, and lustful energy in the dream realm to grant this ability so far.
as things continued like this, the remaining spirits would be moving about the parents awaiting the right moment to make their moves to manipulate the older duo. if for no other reason, then to prevent them from discovering what the kids were doing, or stopping it for now.
