But she wasn't a little child anymore. She was 19 and extremely attractive and sexy. Being around her all the time became difficult for him. He was a healthy man and he struggled to ignore the thoughts in his head.

After two weeks he lost that struggle.

Danielle was in the kitchen that morning. It was a hot day and she wore hotpants. He almost groaned when he walked in to get coffee. She smirked. "Hey sexy. Shouldn't you wear a shirt?"

"Shouldn't you wear pants?" her brother shot back.

"Why? I know you like me looking like this."

"What do you mean?" He had an aggressive look in his eyes, she noticed. That was something new and it intimidated her.

Danielle looked down, suddenly feeling awkward. "I sometimes see you staring," she whispered.

He was going to say that it was untrue but a pang of guilt shot through him. He simply couldn't lie to her, he was too loving and protective. "I know, Sis. I am sorry. It's a bit distracting for me to be around a girl as beautiful a you 24/7. Sorry."

"Well... Is it because you like me? You know - in that way?"

When she looked up she was again shocked by his gaze. He was staring her up and down. And he nodded. "It's not something I can switch off."

The kitchen was silent. Danielle was suddenly aware of her heart beating faster and faster.

"I saw you yesterday. In the shower." She whispered. Her brother's face went white but she kept talking. "Touching your cock. Did you think of me when you did that?"

"Danielle..."

"It made me feel so lonely." Her voice was almost inaudible. "I wished right then and there that you would touch me instead. Touch me for real, not just in your thoughts."

Her brother said nothing but his gaze became even more intense.

"I wished..." She moved towards him and touched his bare chest. "I wished right there that I'd be in that shower. With you. Your cock nudging against me."

"I didn't know you were such a dirty talker", her brother whispered.

"I'm even dirtier than you could ever imagine."

Their kissing was sudden and urgent. Within seconds their clothing fell to the floor and Danielle wrapped her hand around her brother's erection. "You want me to suck you, don't you, big brother," she groaned in his face. Speechless with lust he watched her get on her knees, taking him in her mouth. "Dani", he groaned again. "We shouldn't..."

"Fuck me", she whispered while licking his entire length. "Fuck me and fill me. It'll help us get over all the pain and sorrow. Please."

He grabbed her, lifted her and pushed her against the kitchen sink. Her pussy welcomed him immediately, he penetrated her with one swift move. His voice was hoarse with lust, his hot breath against her neck giving her goose bumps while he spoke. "You turn me on so much, Sis. Are you safe? are you on birth control?"

"No", she groaned. "But I don't care. Risk it."

Danielle's orgasm came quick and intense, so fast that her knees buckled and her brother had to hold her up. He lasted only a few more seconds. "Take it", he grunted. "Take my cum, Danielle. Unfff." She felt him push in deep, the intense throbbing of his rock hard cock and the sudden, explosive heat of his cum inside her sending her over the edge a second time, a second orgasm that made her almost scream and seemed to engulf her whole body.

Panting, they stopped. He slipped out of her, his cum dripping down her legs, collecting in shiny pools on the floor tiles.

She turned around. Her voice trembled. "Oh god. We actually did it. It felt so good!"

For a few seconds she saw the guilt and doubt in her brother's eyes. Danielle wrapped her arms around him and kissed him. "It's ok, it's safe this week." Then she bit her lip and smirked. "Although the thought of you knocking me up is making me all horny again."

He grinned too. "Psycho brat." He lifted her up and carried her to the stairs, his cock growing hard again. "I'm not done with you yet, Sis."
