The fine art of cocksucking

"Get on your knees." Damian commanded her.

He didn't even wait a moment for her to kneel down on her own, digging his hands into her shoulders he pushed her down the the floor.

She'd never realised how much stronger he was compared to her. His grip was forceful but clearly not his full strength, yet she couldn't imagine being strong enough herself to resist his grip. If she changed her mind now would there be any going back? If her brother didn't want to stop could she possibly prevent him from forcing her to keep going?

Before today she would have said her brother would respect her and stop if she'd asked, but now...

Now she wasn't sure Damian saw her as anything more than an object, a toy for him to use however he wanted. She really didn't know if he would stop if she asked, and that uncertainty made her heart beat faster than she'd ever experienced before.

Damian let go of her shoulders, taking in the sight of her kneeling before him. Lilian's cleavage spilled out of her tiny bikini, still wet and properly marked as "Damian's slut". Lilian looked up at her brother, dark eyes betraying his intentions for her. Her parents had always made her feel welcome and loved, but in this moment she felt truly _wanted _in a way she'd never felt before.

Slowly, Damian slipped his thumbs under the band of his pants. Keeping his eyes fixated on her as he pulled them down, lower and lower. Lilian's besting heart fell deep into the pit in her chest, watching more and more of him become exposed as his pants continued to drop.

Her mouth drooled as she finally saw it, the long thick shaft mostly hidden beneath the band of his pants. Her teeth dug into her lips as he gripped it, pulling it of of her pants so she could experience all its glory.

Need.

Her body screamed the impulse at her, she needed to have him. She wanted to touch, to smell, to taste, to experience him in every way she could possibly could. It was as if she was dying and the only cure was the long, stiff piece of flesh hanging over her face.

"First lesson in being a slut." Damian brought his dick right up to Lilian's waiting lips. "How to properly suck a cock."

It took all her willpower to not take it while he had it so close to her. She wanted it so badly, but she was a good girl and a good slut. She wouldn't do anything without her brothers permission.

"A good cocksucking slut can make any man happy." Damian explained to her. "Any girl can get her holes fucked by a guy, but only a true slut knows how to satisfy with just her mouth."

Damian watched his sister stare at his dick woth cock hungry eyes. Was she even listening to him? Were there any thoughts in her head right now?

"Go on then, let's see what we're working with."

Like a starving dog unleashed for dinner, Lilian embraced his cock with a ferocity. She ran her tongue down the length of his shaft, rubbed it against her face, inhailed his scent like it was the only air she needed to breathe. It wasn't enough, she needed more.

She took the tip of him into her mouth, slowly and carefully running her tongue over it to soak in the taste. Like divine ambrosia the taste satisfied cravings that were etched deep in her soul.

"Mmnnghh, fuck that's good." Her brother moaned out as she devoured his cock. "But watch the teeth, open your mouth wider and use your gums to stop them from touching."

Lilian tried her best to follow his advice, it strained her more but she'd do anything he told her if she could keep his dick in her mouth.

"Mmmmhhhh, that's a good slut. Don't be afraid to get nice and sloppy with it."

She was taking him deeper into her mouth now, slowing taking more and more of him down her throat. She wanted all of him inside her, needed it, but she could only take so much before facing resistance. She could make it almost half way down without trouble, and began running her lips up and down that length.

She knew she was doing thr right thing as, his moans deepened and his hands began tightly gripping her chest. Lilian was proud she'd found a way to pleasure him without needing guidance, she knew she had the makings of a good slut.

"Fuck I cant believe my tight prude of a sister has secretly been a slut this whole time." Damian let go of her chest and grabbed the back if her head with both hands. "You've done good on your own, but let me show you how a true slut works."

Slowly but relentlessly he pushed her down his cock, taking her to her limit and blowing right past it. She felt it push deeper and deeper into her throat, almost overwhelming her with a need to gag. She began to panic as he **** her to **** on his cock, uselessly pushing against his tight grip.

Her head convulsed and shd tried pushing against him but she still felt more and more of him stuff her throat. She felt like she couldn't breathe and a sick part of her rejoiced in that, in the thought that his pleasure mattered more than her breathing.

Finally she reached the end, his full length resting snugly in her mouth and down her throat. She could feel and taste ever inch if him, her mind filling with euphoria as her mouth filled with her brothers cock.

"That's good slut." He praised her. "Now keep your mouth open and learn, you'll need to be able to do this yourself."

He pulled her back by the hair, giving her a moment of relief before slamming her back down. He kept pulling her back and forth, using her head as an object as he fucked her face.

Gluuuk ghuurk glluuucck

She gagged out the sloppy wet noises as he ramed her head up and down his shaft. The rough handling only making her tremble more as she tried her best to keep her mouth as open and pleasant as she could for her brother to use.

She endured for minutes as he slowly increased the pace of his face fucking. Her jaw, hair and throat screamed out in pain but Lilian couldn't stop him even if she wanted to. She had **** but to let him use her as a sex toy and knowing that made her pussy drench her mother's tiny bikini.

Suddenly, just as his breathing began to quicken, Damian pushed her off him. Shoving her violently to the ground as he collapsed back against the wall. She gasped for air, desperately wanting do dive her fingers into her aching hole but knew better than that.

She looked up at her brother, his bulging cock twitching as his own fluids dripped out of it. She crawled closer, wanting to keep tasting it but her brother stopped her.

"Wait a second." He said in-between heavy breaths. "I don't want to cum just yet, we've still got so much to teach you."

"Does that mean I did good?" She asked, her eyes sparkling with hope.

Damian looked down at his sister. On all four her tits hung in the air, held together by their mothers tight slutty bikini. Staring at the slutty mark she wore proudly brought him close to cumming all over her. She was still so eager, probably needing to cum almost as bad as he did. She'd do anything he'd tell her to.

"You did so very good my little **** slut. Now let's move on to the next lesson..."
