When Dipper first discovered he enjoyed playing with his backside, he knew it wasn't normal and he should be ashamed of himself. It wasn't his fault he liked to do that when he was masturbating. His body was just sending waves of pleasure in response to the touch. And Dipper knew very well that was his sweet spot. And for the first time he was grateful he knew that about himself.
"Just stick them in the back." Dipper continued. His fists were tightly clenched. His teeth were gritting. His lips were sewed shut in frustration. He had only one chance. One chance to stop Mabel from seeing him like this.
Meanwhile, the demon was still touching himself on Dipper's own bed. He lowered his gaze one more time to his member, a hungry hand still stroking it at a moderate pace. My butt? That's new. He raised himself a little and slid his hand on his backside. His hand caressed his back before touching his ass.
His task was hard giving that his lower half was hanging off bed. Shooting Star will have quite the view when she'll come in. The demon chuckled at the thought. He was still searching his backside for this pleasure spot Dipper was talking about.
Dipper's eyes were horribly concentrated on the other. Dipper was unusually serious. Bill could tell. Although until that point the demon had no trouble exploring his new body, he started feeling a little self conscious as the other's eyes were looking him over. Even if that wasn't even his own body. Dipper was looking at him like he was expecting something to happen. It was unsettling. Even for the dream demon.
Dipper was holding his breath , waiting for the other to find his sweet spot. To get a reaction from him. Anything.
Bill was still wiggling his hips on the bed, trying to reach between his legs from the back. Quite the complicated position Pine Tree is putting me in. The demon spread his legs and squinted his eyes, still trying to reach for the spot.
He was facing the door with his legs wide open, his hips wriggling in the air. Dipper swallowed hard. If my plan doesn't work, things will get a lot worse from here on.
Steps could be heard down the stairs, getting closer.
A mere second seemed like a century to Dipper, Mabel being able to walk in at any moment. And Bill still couldn't even get a hang of it.
All Dipper needed was a little movement from Bill. That's all. And his plan would work.
The demon gave a pleased moan as he finally touched the right spot. He hummed as he rubbed his hand around it. Both of his hands were wet with precum from rubbing his dripping member so Dipper knew it wasn't going to hurt. It was only going to feel good. Dipper frowned as the words formed in his mind. I don't want to make him feel good. His frown softened as he thought. But it's only to get out of this situation.
Bill's hands were working on both his member and his butt, rubbing his wet fingers against any spot that felt good.
The dream demon looked once again at Dipper's floating form and thought: Wait. Why is he cooperating all of a sudden? Is he really trying to help me ruin his body? Although Bill knew that Dipper could trick him, given his lack of knowledge of human emotions and sensations, he decided to go on.
So, Bill, being the self centered bastard that he is, had his doubt replaced with another thought. It was about time Pine Tree finally realized that I am an all knowing interdimensional being, far superior to him and that he should just succumb to me.
The thought pleased the demon so much that he gave a large teeth-showing smile that had Dipper worry about his face for a second. He didn't know his face could form such an unnerving expression. Eventually, Bill decided to do what the other said and stick his fingers in.
He placed his index finger next to the entry and rubbed the place one more time, just to make sure it would go in smoothly. The demon wasn't worrying about Dipper anymore, considering him anything but a threat at that moment.
