With his powers (option 3)

"If you don't leave now, I'll..."

Matt didn't let her finish. He jumped into her mind...

... and bounced right back with an intense burst of what he could only think of as feedback. What the hell just happened, he wondered, shaking his head. He raised his hands to his face, rubbing his cheek now instead of his cock, and that's when he realized Lily had stopped in mid sentence. She was just sitting on her bed, looking at him, one arm across her breasts, the other between her legs, covering her pussy. He found himself wishing she would just relax, that she would want this as much as he did.

Suddenly Lily's hands moved to her sides, and she leaned back, spreading her legs wide for him. "What are you waiting for, Matt? I thought you wanted to fuck me," she purred. "

Matt stopped, staring at his naked twin. Had he just... Then he realized the feedback he felt was more than just feedback. It was as if he was receiving sensations from Lily, his mind connected with both his body and hers. He tested this sensation, making her right hand move up and pinch her nipple hard, twisting it. Matt could feel his own excitement at the sight, but he could also feel the sensations from Lily, a mixture of pain and pleasure he hadn't known could be so close to each other. He moved her hand down to her pussy, still wet with her juices and the sperm their dad had so recently put there, and pushed her fingers deep inside her.

He could feel her body respond to the pressure of the fingers, but strangely he could also feel the pressure itself, receiving the nerve impulses not only from her pussy, but from the pressure her pussy was exerting on her fingers. She fingered her 18 year old pussy, and he could feel the sperm on her fingertips. Matt resumed stroking his cock, climbing on her bed, and he found the closer he got to her, the stronger the sensation of her fingers in her pussy grew. At his thought, Lily lay back, her hand leaving her pussy to join her other on the headboard. "Well," she asked, her feet at the edges of the bed. "Does my dear brother want to fuck me like daddy fucks me?"
