Effect of Mark (R-18)

With the brand on her stomach, Calle wondered what it does. Which she learned as her body turned hotter, her mind turned hazy and her breathing growing more ragged as time passed.

 'Why am I feeling hot?' for some reason, her temperature was rising, or so it felt. She could not tell with her arms and ankles bound to each other, preventing her from escaping. Not like success is possible in the first place. Not when a Demon Lord is watching her.

 However, any thought if escape fled her mind as the heat grow unbearable, especially around her crotch and breast.

 'Why is my privates felt like it is on fire?' she questioned her mind, not wanting the Demon Lord to see her in such state.

 'Wait! The Demon Lord touch me before! He should be the reason for this feeling!' she quickly realized.

 She turned to see an obnoxious smirk on the Demon Lord's face, confirming her thought.
