As Emily began to think of merging with Scott, she noticed him stirring in his bed, groaning. He had a problem downstairs, in his drawers, it seemed. the magic seemed to pulse through the room, connecting her to him. She hadn't realized it at first, but the warmth inside of her was pulsing through her, giving her feelings of pleasure.
Careful not to awake him, she straddled her brother, and leaned down to kiss him as he slept.
His eyes popped open, as a charge of energy surged between the two of them.
She felt a powerful tug yank her downwards against him, all reality seemed to twist and distort, and then she blacked out.
Upon waking, she realized she was in a tangle of sheets on the bedroom floor. Looking around, she saw no sign of Scott. She was about to feel disappointment when she noticed her hair.
It was dark, auburn red, a combination of her ginger red and Scott's black. She shrieked in amazement. Her voice was lower, an alto, instead of her high-pitched former. As she took a lock in her hands, she felt a strange strength in her. Standing up, she was awash with a sense of physical power. Her muscles were more toned, developed. Her face was similar, but tan instead of freckled like Scott, dark-lashed and more angular. She looked a bit older, a combination of her and her brother's faces. But that wasn't the biggest change in her.
As she turned to admire her more chiseled, athletic form in the mirror, she felt the craving in her nethers before she saw it- She had a dick. It wasn't huge, but it was erect and responsive. She gasped, barely touching the thing for it's sensitivity.
So this is what guy's arousal is like?? It's insatiable. She needed to do something with it, fast, soon!
