Bella Investigates

Sniff. Sniff. Her nose whistled as she breathed in the air... and her mattress creaked as she lifted up in her bed. Brandon could feel her eyes on him, then a shifting of her body and a small set of sounds muffled by her bedding. Schlick. Schlick. Brandon wasn't super familiar with that sound, but he knew what it meant.

Sniff. Sniff. She smelled herself and grabbed her phone off the night side table. Pulling up the health app on her phone and checking her ovulation calendar as if that would help explain things... but it didn't. She turned back towards and her brother and sniffed again, stepping out from under her covers and walking over towards his bed.

He felt the urge to cover up, turn and see, but he needed to be still and asleep for this charade to stick.

When she was close enough to see him she paused, glancing at his naked form in the dim light. "Oh, Brandon... you perv..." she said softly. She must have heard him jerking it before. How could she not have, given they've shared a room for so long? Then she noticed the size of his cock; it looked bigger than she remembered, but it had been a while since she'd caught a glimpse of it. Her head cocked and she stared at his motionless form again leaning over him and sniffing again. She knew he smelled different as she took in a big whiff before staring down at his cock, realizing just how large and out of place it looked. She put a hand to her head and grit her teeth. She pushed his covers down just enough to grab around the bands of Brandon's boxers, preparing to pull them up and cover his nakedness, but as she did Brandon took this moment to make use of his new ability, letting his penis grow before her.

He heard a stifled gasp. He wished he could see her face.

Fear filled her mind. She paused and her head turned quickly, her hands pulling back momentarily as she confirmed that her brother was still asleep. Her head swiveled back as her brother's cock swelled to its full size.

"Oh my God!" She whispered as it pulsed before her. She couldn't help but stare at it. She had entertained fantasies about her brother, filling her before, but... that thing would fill her... to... the... brim. Suddenly, the wetness downstairs seemed like it would spill out from her; she pressed her hand to her crotch hoping to contain herself, but as she stared the pounding in her heart and the warmth inside her grew. She nearly reached her hand out to poke it, determined that this was implausible, but thought better of it. Instead, she opted to tiptoe back to her side table and grab her phone.

Brandon saw the flash of light through his eyelids as his sister snapped a photo of his cock.

She paused for a moment and then reached down again to grip his boxers and pull them up, covering his cock, mostly. Lastly, he felt the soft bedding cover his body as she tucked him in. Even in her horniness, Bella was little miss perfect. Why even cover him up? Brandon wondered what made her so considerate, so willing to over-achieve in every way. That picture she took of him may be the only slip up she makes her entire life... finally letting her own desires have a say for once.

She hurried back to her own bed.

Only when she had cozied in under her covers did Brandon turn to look. Glimpses of light leaked out from beneath her covers and the motions she made were undeniably crude, even if the sounds of her moaning and fingering were muffled. He knew for certain that it was the picture of his cock that she was getting off to. The thought of his sister jilling herself to him would normally brick him up, but he was maxed out on stiffness. He couldn't possibly get harder.

He had tempted her partially, got her on the line, but was that enough? He could interrupt her now, give her the real thing... Would she want it though? Maybe he could let her desire build until she couldn't take it anymore. The thought of it all made him want to jerk it again, but what if she heard him and realized this whole thing had been an act?
