Three
For the next couple of months, Frank showed Trinity the art of sexual submission. He fucked her cunt in all different positions all over the house. He'd bend her over the table at dinner and take her from behind. He'd have his little slave sit on top of his cock while they watched TV. He'd interrupt her shower and make her lean into the tile while he took her standing up from behind. And she obediently sucked him off before she went to school most mornings. She loved the taste of his cum.
Sometimes he would handcuff her and not give her any sex and made her sit on the floor between his knees and watch TV. This frustrated her. But every time he held off giving her cock, she was even more ready for intense sessions of submissive fucking.
He told her to avoid the boys who attacked her at school. He wanted her all to himself.
She was in a constant state of arousal and was learning more and more how to talk dirty. This pleased Frank. She was so much more wanton and had more passion than he had expected.
One day, he said he wanted to see her during her lunch hour at school. He found her waiting in front of the school as he commanded her, where he picked her up in his pick-up truck. He didn't take her far away from school, just in a secluded spot behind the gym that was surrounded by thick hedges and trees. It was hidden from prying eyes.
'Jack me off, slave,' he commanded as he parked the truck and stretched his arm on the seat back. In the last few weeks, he had really stopped calling her Trinity and just called her slave or dirty names. It turned them both on.
Trinity's mouth watered. 'Yes, Master.' She sidled up close to him and undid his pants and took his half hard member into her gentle hands and jacked him off as he trained her to do. 'Your cock is so hard, Master,' she said with awe. 'It's so big in my dirty little hand.' She went on with her smut talk just like he taught her.
'When I'm about to cum, put your smutty little mouth on me and suck me dry,' he grunted, as he felt her ministrations work their magic on him.
'Yes, Master,' she quietly obeyed. 'I love the taste of your hot cum.'
He moved slightly away from the steering wheel so she could get her head over his cock and she began licking all the pre-cum off of the head, when he began to guide her motions faster.
He came in her mouth and she moaned, loving the taste of her Uncle's cum. He left her wet and unsatisfied, but no matter. She ate her lunch after the episode thinking that food tasted better with cum.
The next day, he came again to school at her lunch hour and took her over to the hedges and made her climb on top of him and fuck him in the truck. He made her unbutton her blouse and unhook the front clasping bra so he could fondle her naked tits while she fucked up and down on him in the passenger's seat.
He made her talk dirty as she was bouncing on top of his hard cock. He made her do all the work as he sat back in the truck commanding her to fuck faster and talk smuttier. She did as she was told, sweating as she pistoned her hungry cunt up and down on his big hard cock.
For the next week or so, her Uncle picked her up at lunch and had his way with her in some fashion. The last time he came in her hair and told her not to touch it. That afternoon she smelled her Uncle's cum in her hair and couldn't think about anything else but fucking.
She was ready for the next phase.
The next day, Trinity rushed home from school. Her Uncle Frank didn't pick her up at lunch... she really missed fucking him in the middle of the day. She wanted to be with Uncle Frank. All day in class, she couldn't stop thinking about the secret, incredible things he did to her with his cock. Her body tingled with anticipation all day long.
She walked in the house a little out of breath. Uncle Frank was sitting on a bar stool at the kitchen counter drinking a beer, waiting for her. Uncle Frank smiled at her. She was still shy and blushed. His leer promised her an evening of lust and sexual adventure and submission. She couldn't wait! Just the thought of his dominate cock made her tit nubs hard.
Uncle Frank had the thin leather wrist bonds in his hands. 'Hey pretty thing,' he cooed. 'How was your day today?'
Trinity put her books down and saddled up close to him, crushing her massive tits on his chest and breathed into his lips, 'I couldn't stop thinking about fucking you, Master.' She put her wrists on the counter awaiting her bonds.
'You fucking slut,' he murmured. She loved it when he called her such dirty names. He kissed her hard and made her suck his tongue until she moaned. He grabbed her wrists and easily fastened the bonds. 'Come with me,' he ordered and headed straight for the bedroom.
She sighed happily. 'Yes, Master.'
Frank ordered her to strip. He got behind her and pinched her nipples and squeezed her tits while rubbing his cock against her ass.
'I want to try something different tonight, sweet sex slave.'
'Anything, Master,' she sighed. 'I am your submissive sex slave. Here for your pleasure.'
'Oh you are a dirty, dirty girl,' he said as he dipped his finger in her sweet juicy cunt. 'Now, face the bed, kneel down at the end of it, on the floor.'
She went down and he grabbed her wrists and connected the bonds to the bedposts. The bonds felt sexy as her hands wrapped around the wrought iron cylinders. She was tightly bound and it felt glorious. He could do anything to her and she couldn't get away.
'Now, my sweet sex slave,' he whispered in her ear. 'I'm going to suck your juicy cunt while you suck cock.'
Not thinking of the logistics of that proposition in the position he tied her up in, Trinity moaned and closed her eyes as his hands roamed her tightly bound, naked body. Then she realized there was another set of hands on her tits.
Startled, she opened her eyes. 'What --?'
There was another man sitting in front of her! Her Uncle kneeled behind her and gripped her waste and put two fingers in her cunt as he rested his chin on her shoulder.
