She might be a little bit of a terrible person.

"I think....not." Sarah said slowly. "The thing that you said to me, they hurt. After all that I endured trying to protect you, my princess and my friend. After everything I took before I broke, for you to simply barge in with no understanding of my torment..."

"I'm sorry! I'm sorry, okay! I didn't mean it! I didn't know!"

"You'll know now." Sarah said, shaking loose another drop of the liquid. This time, it took Susan on the side of the neck. She recoiled, yelling again in the hopes that someone would hear her. She managed a strangled gasp as the potion kicked in.

"Oh my god, Sarah. I can't... I can't think... Ah! This is...this is even worse! Please don't do any more! Please stop!"

"That's what I said too..." Sarah said, shaking her head. "But of course, they didn't. So I endured more. All for you, Susan."

She reached out from behind the throne, her hand caressing Susan's right breast. It was warm to the touch, and at the first contact, Susan jerked. She groaned, and threw her head back, gritting her teeth in an attempt to control it. But she couldn't, it was like a jolt of lightning. Her breasts were so aroused, so sensitive.

Susan watched again as Sarah took up the hated bottle, she winced as it came close to her skin, her eyes widening, she strained her muscles, fought the rope, but she couldn't win. She'd already tried. Sarah touched the top of the bottle down against her lower belly, and she froze. An instant later, the desire pounded through her again. She wanted to cry and to scream, she wanted to beg for release. Her muscles tensed, and her vision blurred. Her lower self continued to drip, a small puddle had formed on the throne under her.

Carefully, slowly, with agonizing smoothness, Sarah drew the bottle along her body. Susan shook and begged, but she could not do anything to free herself as the line of fire rose across her belly, tracing gently over her stomach, and then started to inch towards her breasts. Desperately, she shook her head.

"No, no, nonononono. Sarah, please stop this. I can't take it if you drip that thing on my breasts! I already feel like I am burning up... I'm already dripping wet... Please don't keep going!"

"I will keep going." Sarah said. "Until you know what it's like. Until you feel the same shame and humiliation as I felt."

Susan writhed, throwing her body back, gasping as the potion inched closer and closer to her delicate chest. Just as it got to the very base of her breast, Sarah stopped. Considered.

"I will tell you what." She said. "I will not touch your breast if you can do something for me."

"Okay, okay! I'll do anything!"

"Suck on the bottle."

"What? You mean like a baby?"

"No." Sarah laughed. "Like a cock. Have you ever done that before, given a blowjob?"

"N-no."

"Of course not. You're a princess, I doubt you would be able to do such things. Consider it a bit of practice."

"But if I suck that, the potion will.."

"You will get it in your mouth and throat." Sarah nodded, her eyes glinting. "But if you don't, it's going on your chest. And not just a few drops either. I'll be sure to use a lot more of it. Then, I am going to start tormenting you. Stroking you and teasing you, you know? Not enough to make you cum, but enough to keep you on edge. I'll use the potion until there is none left, then my fingers, my hands... my mouth. I am going to lick you, and make you beg and scream to cum. But I am not going to let you do it. You're going to remain like that until someone comes here tomorrow, and they find you all wet and wanting. By that point, you'll be so far gone you'll do anything to get relief. I wonder how they're going to use that against you?"

“Wh-why are you doing this? I thought you were supposed to be my friend!”

“That’s what I thought too.” Sarah said. “I guess we were both wrong, huh?”

“F-fine! I’ll suck it!”

Sarah pressed the bottle up against Susan’s face, and the other woman reluctantly opened her mouth, the cold ice made her jaw ache. Sarah pushed it deeply, until Susan felt like she wanted to gag, but worse than that, the potion itself dripped out onto her tongue, and she recoiled as the same damned heat started to burn in her mouth. She shook her head, moaning around the bottle desperately, and when Sarah withdrew it, she gasped.

“My mouth! I feel it going down my throat! I feel...I feel….”

“Did you taste yourself on that as well?” Sarah asked. “I am sure you did. You dripped all over it. Your pussy is so wet right now. One would think that this is some fetish of yours. I guess I shouldn’t be surprised. Princesses are women too, right? So of course you have things that turn you on.”

Susan tried to argue, but she found that she could not speak. Her mouth felt ablaze with sensation, and even the feeling of her own tongue moving across her lips was agonizingly seductive. After a moment, she managed to get herself in order again, and looked just in time to see Sarah preparing to use the bottle again.

“Wait, no! You promised!”

“I said not on your breasts. Not anything about your nipple.”

Susan screamed as she felt the liquid drip onto the tip of her breast, her pink nipples, already erect with arousal, strained even more, and she shook her head, unable to escape the moan which tore its way free of her throat. She was **** to endure the tide of desire which crashed against her as it was applied first to one nipple, then the other. She hissed, and tensed, and writhed, her body straining, her mind screaming. Her head shook back and forth, as if trying to deny the whole thing. And all the while, she felt herself coming closer and closer to that edge. But she couldn’t cross it, and that was the most upsetting part. She wanted to climax. She wanted to cum. But she couldn’t. Sarah wasn’t letting her. She felt lost, trapped in her own body. Betrayed by her own quivering flesh.

“Haaah.” She gasped for air, trying to see through the haze which now obscured most of her vision. “I….Oh fuck… oh god...”

“It’s worse, isn’t it?” Sarah said. “When it’s applied to your delicate places one at a time. Just having it in your pussy is pretty bad. Believe me, I know. But that’s just one source. You can fight that. But having it in several places… your breasts, your belly, your pussy, your mouth… it’s overwhelming. You can’t fight that. It’s like a tide which sweeps you away.”

“Sarah!” Susanbegged. “Sarah, place… I’m sorry for what I did to you I am-Ohgod-I am so sorry! P-please show me mercy! -fuck!- Ugh. Ahh. P-please help me...”

“You want it to end?” Sarah asked, pressing forwards. “You want to climax? You want to cum?”

“Y-yes! Oh god yes! More than I have ever wanted anything else! P-please!”
