Sam was in deep dilemma for what's happening. First time he was possessed by his spirit and attacked Nox then second time while everyone having dinner, he got replaced again by his spirit which attacked Nox again. Even if he wanted to attack on her, it must be him not a spirit with lustful nature using his body. Right now, his spirit of pleasure and deception taking over every time he trys to stay away from Nox. Then Nox, The legal loli turned into a milf. Her 2 sizes of top and bottom was even bigger than his mother, when he thought that his spirit had enough, at movement his spirit attacked on her again. Surprisingly his spirit used same moves as he did when he was with his mother. The C.A.T., The Sunday Afternoon, The Pirate Bounty, Edge of bed which turned in edge of table.
Sam was really feeling treble from inside. If we talk in metaphor then imagin that he was given food in a plate to eat, even if he dont want to eat, it's still his food. Now someone taken over his body and eaten his food, while he sitting on other side seat in mindscape. He eaten his food but he can't feel it, and it turns into treble feeling.
After dinner of Sam and Nox, spirit changed her seat with Sam again to let Sam take care of mash his spirit made. Nox was like splashed in hot sticky milk and she lost he consciousness again because his spirit canceled all spell other then enlargement on Sam's little brother. Sam just wanted to ask Nox a question about flower but his spirit just made mash again.
Even if Sam don't want to be related to this mash, his body indeed used in this mash so he just shy away from responsibility. Sam picked put Nox and want to bathroom when his mother Angela instructed him. Angela told Sam that even if he was not in control of his body, his body was indeed in used in this deed so it's Sam's responsibility to take care of Nox.
Sam can see that the Nox has grown bigger in bathroom, he has to self control his thoughts and body so he don't and up attacking on Nox. Sam never had mother in his previous life as Mr. Philips so he end-up developing milf taste. And he was bathing a unconscious milf in his hand. It's really hard to resist fetish if one is too much in it. In previous life as Mr. Philips, He went to brothel many times wearing mask but in the one of the girl removed his face mask and killed herself and he kicked out from establishment. Later when he tried to went another brothel he found that he has to remove his mask and show his identity which was not even possible. His Identity card never had photo afterall who wants to die or widespread photo of disaster.
He cleaned Nox and put her in her room.
Sam was wearing green wearing green hat right now if we use Chinese slang. His own spirit NTR'ed him twice, while all he do is watch. Sam had another thought that he already attacked Nox twice but Nox co-operated with his body because she don't wanna hurt him or his body. And if his mother is not bothered with Nox invasion in their privacy then her mother Angela must have made promise to each other. It's not much common in previous world but its happened many times in past that 2 sister end-up in marring same man because of promise between sisters. So since Nox called Angela 'Big Sis' everyday then they must have made promise with each other. And this is magical world, not like previous world, so this kind of things are not uncommon here.
Sam was strong supporter of monogamy but here because of his mother he decided to accept, so his mother's promise doesn't go void because of him. Also the figure of Nox was same as his taste, a milf what he likes. Twin big mountains, which was in his hand at bathroom. Big bottom for great grip, he can can even slap them for arousing black dragon. As she was a pervert, he was pretty sure this will put her body on fire. Last time Nox was so much in heat and possessed Sam's momentum was there that if Sam can come out, it would be him conquer Nox not his spirit. So Sam decided to let Nox enter his personal space with his mother.
But still he felt that he was wearing green hat or having green hair even though he had dark orange hair because of being flaming dragon.
