Heather's going to honor her bet, like it or not

Billy’s cock was stiff as a board after watching the show that Heather put on, and he needed to get his rocks off. He knew that she had no intention of honoring the bet, but decided to use that **** to make things more interesting. In fact, to make his **** more effective, he pushed into her sleeping mind and strengthened her embarrassment at being seen nude and cumming in front of her brother. He also increased her resistance to fucking Billy, and made it so that she wouldn’t realize that he was nude until her told her. Then he gently nudged her shoulder until she started to wake up.

Billy sat next to Heather on the bed, with one hand caressing her breast. Heather rolled onto her back, eyes still closed.

“Mmmm, that feels good,” she said sleepily.

“Glad you liked it,” Billy replied.

Heather’s eyes shot open. “Billy!” she screamed, wrapping the covers around her naked body, “what the fuck are you doing?”

“Don’t you remember our little bet?” he asked.

Heather’s eyes grew wide and her face flushed red, as the memory of just a few moments ago came rushing back. “That was real? I thought I dreamt that. How did you... What did you do to me?”

“Never you mind how. Just remember that I made you cum without laying a finger on you, so you lost the bet. Know what that means?”

“That I’m your ****?” she said, dejectedly.

“That’s right, Heather.”

“Fine. Just get out of my room so I can get dressed, and then I’ll do your homework or clean your room, or whatever the hell you want.”

“No Heather, that’s not exactly what I want.”

“Then what do you want?”

“Let’s just start by taking these covers back off you.”

“Come on Billy- you’ve already seen me naked. Isn’t that enough? I mean, you’re my brother for chrissakes. You shouldn’t be seeing me like that at all!”

“Cut the shit, Heather,” Billy shot back, angrily. He got up, stormed around to the foot of the bed, and grabbed both of Heather’s legs. He yanked on her legs, pulling her down the bed, the covers slipping off her, until her ass was at the edge of the bed and he was between her spread legs.

Heather started kicking and struggling, so Billy leaned his weight on top of her, taking her arms and holding them at her sides, his erect cock resting on top of her hairless little slit and flat tummy. “You and I had a bet. I made you cum without touching you, you lost the bet, and now you have to do whatever I say. And I say that you’re going to let me fuck you, understand?” With that, he allowed Heather to notice that he was naked too.

Heather’s eyes bulged when she realized that her naked brother’s cock was sitting on her stomach and pussy, and she redoubled her efforts to break free. “Fuck off! You’re a sick, demented pervert- I’m NOT going to screw my own brother. Now get the fuck off of me!!!”

Billy leaned in close to his sister’s bright red, sweating face, noticing the veins bulging in her neck and forehead. Calmly but firmly, he said, “Last chance Heather. I made you cum without touching you- you know I have ways of making you cooperate. You’re getting fucked either way. So you can either honor your bet and do this willingly, or else I can make you cooperate. Which is it going to be?”

The moment he finished speaking, Heather spit in her brother’s face, the saliva hitting him on the cheek and dripping down.

“Very well- you’ve made your choice.” Billy stared into Heather’s eyes and entered her mind. “Your mind remains free, but your body will obey Billy’s every command,” Billy pushed into her thoughts. “You can say and think whatever you want, at least until I tell you differently. But no matter what your mind thinks, no matter what it tells your body to do, your body will react instantly and enthusiastically to anything Billy directs you to do or feel, and you will honestly answer all of his quesions.” He exited her mind.

“I’m going to release your arms, Heather, and I want you to stop struggling and lie still,” he said to her out loud.

“Ha,” Heather laughed angrily, “I’m going to tear your fucking head off.”

“We’ll see,” Billy replied. He released her arms and stood up at the foot of the bed, wiping her spit from his face.

The moment he let go, he could see in Heather’s eyes a flash of anger as she tried to attack him, followed by confusion as she realized that her body wasn’t responding to her mind, quickly transitioning into fear.

“What did you do?” she asked, panicked. “I’m paralyzed! I can’t move my body!” She started to hyperventilate.

“Calm down,” Billy instructed, and her breathing slowed. “You’re not paralyzed. You just wouldn’t honor our bet, so I had to take control of your body away from you. Watch.” Billy took a few steps back.

“Rub your nipples,” he instructed. Heather watched in amazement and fear as her hands moved from her sides to her chest, and her fingers began dancing across her sensitive nipples.

“Oh my god,” Heather cried out, “I can’t stop. How are you doing that?” She was now bright red from shame and embarrassment.

“Never you mind how,” Billy answered. “Now slide down a little more so that your ass is hanging off the edge of the bed, and spread your legs wide.”

Heather’s body did as instructed, her hands never leaving her now rock hard nipples and crinkled, pink areolas. Her feet hung down off the bed, and her thighs were pushed out as far apart as they could go, leaving her cute, smooth little pussy on display with its slightly parted lips.
