"Damn I need to get my own place" Alex said to himself as he grabbed his psychology book.

He flopped down on the bed grumbling to himself. At 22, Alex had moved back in with his family after being discharged from the Marines, but, sometimes, being back at home rubbed him the wrong way after being out on his own. His parents had agreed to let him have his own room back while he attended college. His 18-year-old sister Jenny was still at home too, making for a full house.

Tonight, for once, he had the house to himself. His parents were gone for the weekend at some conference and Jenny was out on a date with her latest boyfriend. As he studied his thoughts drifted to sex. He had only dated the last girl for a month before she started the commitment hints, so Alex decided to take a break from the dating scene for a while but the self imposed celibacy was starting to take its toll on his concentration.

His drifting mind always seemed to lead to his little sister, Jenny, with her long brown hair, completely innocent face and a body that was every man's wet dream.

Alex gave up trying to study and just laid back picturing Jenny in her white cotton bra and panties. He thought of all the times she wore those too short skirts when she was bending over giving everyone a view of her panties, or the baby doll tees that she wore just to show off her tits. Just the mental picture of those pure and innocent underclothes made him groan as his cock started to rise, so he stripped down to indulge himself.

Just before settling back to enjoy his fantasy he heard a noise downstairs; it sounded like someone giggling. Deciding that he had better check it out he grabbed his robe and crept down the stairs. Stopping behind the ferns that hide the bottom of the staircase

Alex was enthralled with the scene before him.

Jenny sat on the love seat with Zeke, her newest boyfriend, their backs to the stairs. "Geez, this guy slobbers more than our dog." she thought to herself. They were half lying on the couch with Jenny's shirt unbuttoned and her bra pulled up to her neck. Zeke's hands were occupying themselves with her tits while he shoved his tongue down her throat. Jenny sighed softly and used her own hands to keep Zeke's in the permitted areas.

"Come on baby. Let me in your panties," Zeke said in a hoarse whisper. "You've been backing down for over a month with excuses; now is the perfect time. No one is home."

Jenny tried to push herself up and pouted. "I told you that I don't feel ready for that yet."

"You fucking little tease you never feel ready" Zeke fumed as he grabbed Jenny and pulled her back under him, one hand ripping her panties away.

As Jenny struggled to get free her skirt rode high onto her hips leaving her pussy wide open to Alex's view. Zeke covered her pussy with his hand trying to hold her still enough to get a finger inside.

Jenny was frantic, she had never let a guy go so far with her before and now Zeke was trying to rape her. Remembering what her mom had told her about self defense, she took a calming breath. Pasting a sweet smile on her face she looked at Zeke.

"Baby slow down, I'm sorry. Let's do this the right way, I want this to be right," she whispered. "Her hands stroked Zeke's back as he listened to her words. "If you are going to be my first you want to show me right don't you?"

Zeke's manhandling had stopped.

"That's a good sign," she thought to herself.

Alex couldn't believe what he was seeing. He wondered what his little sister was saying to the poor slob. He knew his sister was a tease, she had been teasing him and all his friends for years. His hand was on his stiff cock sliding over it. Moving the ferns out of the way quietly he crouched down to watch the show. When he saw Zeke forcing Jenny he didn't even think to help her knowing she had it coming from men everywhere, but leave it to Jenny to take control of the situation and the man pant like a puppy.

"She really needs to be taught a lesson in treating a man right"

Zeke had backed up a bit giving Jenny some more room. She slithered out from under him keeping that little smile on her face until she was out of arm's reach. "GET. OUT. NOW." She yelled at him furiously.

Zeke smirked at her, here she was acting like the injured female when he knew that she liked it up to when he went too far. Her bra still pulled up she pointed at the door.

"No problem babe." He said to her, "You are just a little virgin tease. One of these days you are going to get what you deserve bitch." Walking by grabbed her ripped panties handing them to her as he bowed sarcastically.

Hearing the door slam shut, Jenny tried to arrange her clothes, fixing her bra and buttoning her shirt unevenly. Sitting back down on the couch she hugged her knees to chest unknowingly giving Alex an unrestricted view of her pussy. Jenny started to think about what Zeke had said. "So I like to show off a little. Teasing and showing off are way different," she thought to herself. She liked the reactions that men gave her when she caught them looking. It made her feel powerful and sexy.

Her hand slid down over her tits, squeezing them as she thought about how men's eyes were drawn to her when she entered a room and how she heard Alex's friends talking about how they would love to get into her pants. Little did they know she was still a virgin. No matter how much the teasing them turned her on she just wasn't interested in the idea of some teenage boy groping his way around trying to figure out where to stick it. She needed someone with some experience, someone a little older.

Maybe one of Alex's friends could be her first. She had heard them talking about sex enough to know who had the most experience -- besides her brother that is.

Not that he didn't have a great body -- a four-year stint in the Marines would give anyone a body that women would swoon over.

Her hand ran down to her naked pussy while she thought about Alex and his friends.

Alex couldn't believe his luck! Here was his baby sister getting herself off right in front of him. He tried to move for a better position but hit the ferns by accident. Ducking down behind the chair he hoped that she didn't notice.

It wasn't to be though as he heard her scared voice asking "Who's there?"

Chuckling to himself he let her fret for a moment before he stood. He saw her shocked face and was glad the chair his his raging hard-on.

Jenny glared at him not even realizing her skirt had ridden up. "What are you doing home? Why are you spying on me?"

Alex just let his eyes roam her body as he steps nearer the couch. "I am home because John canceled going out tonight and I am not spying on you I am just watching you be a little prick tease like usual."

"How long have you been here? What do you mean prick tease? Zeke almost raped me and you just sat and watched?" She stood up while she yelled at him, her chest almost touching his. Realizing how close he had gotten she stepped back and bumped into the couch.

"He didn't rape you Sis. You deserve what you got. You deserve more than what you got actually. I mean you are always making sure every man sees your little white panties or your tits.

"Half my friends wish they could get you into bed. You have every man standing at attention and drooling over your sweet little face and body.

"Even me" He gestured down and she noticed the tent in his robe.

"I can't help it if you men can't keep your hormones in check," she spat. "It isn't my fault you can't keep a girl long enough to get a piece. So screw you big brother!"

Jenny tried to push him back and around him but Alex dind't budge. He grabbed her arms as she tries to push him away; her little taunts had driven him over the edge.

Pulling the belt from his robe he spun her around quickly wrapping the belt around her wrists. She started struggling against the bond, squirming wildly to get out of the well-tied knot.

"What the hell are you doing you fucking asshole?" She screamed in his face.

He could barely breath; his voice was a croak. "What someone should've done a long time ago, Jenn. Taking you in hand"

Horrified, Jenny stared into his eyes. He was looking from her to the exercise room he set up when he came back from the Marines. The one her dad helped him set up. The one they soundproofed.

Jenny was scared.

Alex's thoughts raced through his head. He tried to tell himself this was his sister but he could see all the little flashes. The games she'd been playing... Maybe he could scare her. Just scare her and play with her a little, that's all.

His eyes snapped back to hers filled with resolve to teach her a lesson. He reached underneath her and finally let out a breath as his hand slid up the back of her thighs to her pert little ass. He cupped I and monaed as he felt her skin for the first time, then easily lifted her over his shoulder. His other hand absently reaches over to grab her torn panties as he carried her toward the room.

Feeling herself lifted Jenny squirmed and tried to kick out but Alex was too strong and far too well-trianed to let a little squirming dislodge her.

His other hand came back over, holding her legs tight until he reached the door to his exercise room. He felt her shudder and shift, then sighed as she started to scream, even with no none else around.

He pulled her down to her feet and looks at her, then down at the panties in his hand.

Jenny had a moment's relief as her brother pulled her down. Then she saw the glint in his eyes.

"You know you should be quiet," he said in a low voice.

Jenny sensed the danger in his voice but couldn't stop herself as she screamed in his face. "You fucker! Why are you doing this to me you pervert!"

She only saw a blur as the back of his hand struck her cheek. Tears welled in her eyes as she felt her cheek burn from the slap. She was scared. Why was she wet?

"Please don't do this Alex. I'm you little sister remember?"

She still had her eyes down, and she watched as her brother's hand formed a fist with the thumb out. He shoved into her abdomen.

The pain was intense. Fresh tears fell filled her eyes. At that moment she knew she would do anything to make it stop.

Alex knew he was losing control of himself. His cock jumped as he saw her tears. He shouldn't feel this way. Shouldn't let his cock take control. Not with his sister. Even if she deserved it. Someone was speaking. It took him a minute to realize it was him.

"I'm your brother. I'm also a man. And a Marine. You should've remembered that."

God... those tears... He leaned in and with a flick of his tongue tasted the salty drops on his sibling's face. His cock lurched again. This shouldn't be turning him on so.

More tears ran unchecked down Jenny's sweet face as she fought to pull away from him, fighting to control the pain. She opened her mouth, gasping, trying to speak, and he pushed the panties in deep. Her eyes stayed on his as he looked up and down his little sister's delicious body with those innocent white panties stuck in her mouth, her eyes wide with fear - and, he was sure. Tears still streaked down her angelic face; he could see the sheen of sweat and saw her chest heave as she panted.

His cock felt like a molten iron rod.

He knew as he looked at her they'd be lost if he took her into that room. But the part of him that was screaming to stop was getting further and further away. He'd wanted that little body for so long, and for so long she'd teased him. Him over all other men. "This," he thought, "Is what she's wanted deep down anyway. From now on I'll possess her.
