Billy closed the blinds. It wouldn't do for Diana to open hers and see him and his naked sister. He turned around, masking a feeling of superiority with a lusty gaze. Still, this was his sister. There were still boundaries.
"Okay, Heather. You want me? Give me a blowjob." He smiled to himself as her eyes lit up. She moved toward him quickly as he relaxed on the bed. Her experienced hands quickly stripped him from the waist down and began to play with his rising manhood. Her tongue teased his balls as her hand gently stroked his shaft to life. She stared at his full hardness, as if surprised at how big her brother was.
With a lust-filled smile, Heather kissed the tip, then let his full length slide into her throat. Billy moaned despite himself. Diana's oral skills had been good; Heather's were masterful. Each twitch of her tongue or slide against her cheeks made him feel ready to launch a massive load. Self-control was the only thing keeping him from coming too quickly.
Billy's mind raced as he entered Heather's, looking for anything he might be able to use for some fun against her. He could still feel her desire toward him, her deep-rooted desire for attention, her addiction to orgasms. Not letting himself become distracted, he brought all three of these as close to the surface as possible. Her oral ministrations became faster, more frenzied, but no less masterful. Billy knew he couldn't hold back much longer and grabbed her hair, forcing her down on him.
She squeezed his balls tightly, the pain spiking into his pleasure as he released a massive torrent of semen into Heather's waiting mouth. He could hear her moaning around his cock; the sensation just brought forth more and more cum. Her lips wrapped tightly around the base of his member. Billy pressed into her mind, and triggered an orgasm in her every bit as strong as his own.
The euphoric feeling ebbed slowly, and he watched down his own body as Heather writhed around between his legs at the feeling of her own climax. With new clarity, he pressed suggestions into her mind.
*Heather, you will be unable to achieve another orgasm until you have achieved a specific set of results. You must find and seduce every virgin in your graduating class. Until you have brought each of them to orgasm at least once, you cannot have one yourself. You will, however, feel a similar euphoria to your partners' when they achieve their first, but only their first.*
Billy watched as Heather's moans softened. She breathed heavily against his scrotum as she watched his cock grow flaccid.
*You will also feel extreme disgust at yourself for wanting to have sex with Billy. At the same time, you will continue to feel that same desire. You want him to come to you, you want him to be the initiating person. You'll do anything to get him hard and lusty toward you, short of revealing this disgusting incestuous desire to anyone else.*
Heather's face changed, going from sex-crazed to disturbed in only seconds as she continued to stare at her brother's crotch. She stood and wordlessly left the room, stopping only for a moment to gather her robe.
After a few moments, he stretched out his mind again and found Heather, furiously trying to get herself off. Smiling to himself, he reached out to Diana and found her sleeping. He woke her with a strong, screaming orgasm, then mind-cuddled with her until she slept again.
Then the nightly oblivion took him to sleep. |
