Then very quietly he crept behind her, and in one sudden motion placed his hands on her waist.
'Now I got you!' he shouted, and he held her tight. Robin jumped a bit and screamed in fright, enjoying his touch, his strong hands for just a minute.
'Let go of me!' she yelled at him, and pulled away. 'Don't you ever touch me again.' She gave him a stem look, then walked into the other room.
'Just because you're an impotent virgin doesn't mean you can go around touching me, you big loser.'
Billy could feel his excitement rise from the touch of her warm, lovely flesh. He watched her ass swing from side to side as she walked into the living room. He had never been this excited before. His rod was so hard, he thought it was going to burst from his wet trunks, and after adjusting it to a more comfortable position, he followed her into the living room.
'Why don't you like me?' he asked her.
'I like you. I just don't want you touching me.'
'Then why do you make me think you want me to?'
'I don't. That's just in your head. I wouldn't want you to touch me with a ten-foot pole.' Robin stretched out on the couch, rubbing her belly softly.
'Can you massage my back, big brother? It's so tight back there.'
His eyes opened as she turned on her stomach, waiting for him. She wanted to tease him some more, and he knew it. But he couldn't resist touching her soft skin. He knelt on the couch, straddling her little waist, locking her body inside his knees. He looked down at her waiting body, following her spine all the way down to her wet bikini, over the luscious curves of her waist and shoulders, to her silky blonde hair. It was like she was his prize, just lying there, waiting to be screwed. His hands dug into her soft shoulders and started grinding away. He dug his thumbs deeply into her, and she sighed in relief.
Robin began moaning in pleasure, trying to get him excited and doing a good job of it.
'Right there, Billy, that's perfect!' she sighed, and he pushed his thumbs into her golden flesh even deeper. He felt his dick getting magnificently stiff and large, and he pressed it hard against her bikini-clad ass. The wetness of her suit cooled him off a bit, but not nearly enough.
'Watch that!' she shouted at him, and he lifted his crotch up from her ass a bit. The bitch, he thought. This was the kind of girl that needed to be taught a lesson. He started to dig deeper into her precious skin, nearly clawing at the middle of her back, trying to hurt her.
'Not so hard, Billy.' But he ignored her and only dug harder. His thumb caught on the bra of her bikini, and he wanted to untie the strap, but he was still scared of her. He wanted to rip the thing off her and fuck her like he'd never fucked anyone before, she excited him so much. But when she felt his hand on her strap, she spoke.
'Leave that alone,' she demanded. So, instead, he ran his fingers very lightly down her spine, making circles in her moist flesh with his fingertips, trying to arouse her.
'Does that tickle?' he inquired, but she remained silent, holding her face to the bed. And now he was caressing the small of her back, pressing down, relaxing her, slowly making his way to the crest of her ass where he found the elastic of her bikini. He cupped the moisture from her suit in his hands, then spread it on her back, moving down to her buttcheeks.
'Watch it, horny brother. Don't go any lower than that.' She could feel his excitement rising, driving him wild with passion, and she was delighted that she could arouse him so very much and not fulfill him. But his excitement was vibrating onto her, as she felt her juices flowing, too. Now he was lowering his erect cock down to her butt again. And now he was grinding his crotch against her, trying to massage his aching rod. He wanted to rip everything right off her and stick his tool in her snatch, but he just didn't have the courage. He'd never had the courage. All his life he was always scared to make that final move, and that was why he was still a virgin.
Robin felt him grinding against her, his boner rubbing against her wet bikini, massaging her ass. But she wanted to tease him some more.
'Cut that out!' she cried, and she raised her head, looking back at him. 'What's wrong with you, anyways? Can't you ever be around a girl without getting a hard-on?'
The words pierced him. He stopped rubbing her back and froze on top of her. She was making him angrier.
'Want me to do your back?' Robin suddenly offered, looking back at him and seeing him smile at the words. He agreed, and they switched positions. He was now lying on his stomach, sinking deep into the couch, and now she straddled his waist, enclosing his wet trunks within her legs which were so long and soft. She made sure she was comfortable, squirming a bit on his ass, feeling him tingle with every one of her movements. Now comfortable, her legs bent in front of her, she touched his shoulders with her toes, and he felt a wild sensation run down his back. What a soft touch she had!
And in one motion, she was pounding on his back furiously, touching and hitting every muscle she could, so that his entire back felt like it was being vibrated. Her touch was so warm and soft, yet it was so quick. She was stimulating every muscle and fiber in his back, and he'd never felt anything like it before.
And she knew it, too. She was delighted that she was turning him on so much.
'Like that, big brother?'
'Don't ever stop,' he sighed.
When she stopped pounding his back, and he just lay there motionless, feeling that tingling sensation that was echoing throughout his body. And then she began running her fingertips very lightly over his shoulder blades, around his neck, giving each spot a tender touch that excited him wildly. Every stroke of her delicate fingertips caused a tingling throughout his body, and she knew it. She was trying to inflame his desire on purpose. Her fingers probed down his strong back, touching the muscles that had taken him years to develop, down between his ribs, tickling the soft and eager flesh down his spine, her fingers stopping at his trunks. He was so filled with yearning for her body that for a moment he shivered from her wonderful touch. He'd never been this excited, and he could taste her luscious body in his mouth. He swallowed for a breath of air, waiting for his sister to touch him again.
'Don't stop,' he begged. She touched his back with her palms.
'Getting excited, big brother?' And she dug her nails into his skin, trying to hurt him. But Billy loved it, and he pressed his swollen prick against the couch, moving up and down, frying to ease the ache in his balls. Now she was clawing him over his shoulder blades, down his back, around his waist and finally ending at his butt. Her thumbs teased the inside of his trunks for a moment, and he wanted her to take them off, but then she removed her hands completely from him. He wanted her so bad, and she just loved to tease him like this.
'Take it easy, Billy. It's just a back rub,' she told him. 'You're the horniest motherfucker I've ever seen – for a virgin.'
Her playing with him and then making fun of him was getting him very mad. He wanted to fuck her so bad, he was on fire. And every time she started to bring the fire out of him, she pulled away. It was so irritating, he thought. But in a sudden jerk he rolled over on his back, so that now he was facing his sister. She was looking down at his manly chest, searching him out with her eyes, trying to make him hornier. He was staring at her tits now, which seemed to flow right out of her small bikini, out onto his lap. He wanted to rip the thing off her, and now he pushed his crotch up against the inside of her thighs. He could feel her warming up to him; he could feel her vibrating with desire, too.
'That's all,' she said, and started to get up, but Billy held her hard by the arm. She was getting scared now, and all of a sudden she could see how very strong he was.
'You've lost your mind,' she said, and tried to pull herself away from him, but she couldn't. Now his hands were running up and down the smooth skin of her arms, caressing them gently.
'You like to tease me, don't you?'
Robin looked at him for a moment, then answered. 'You're crazy! You're a sex maniac!' she screamed, trying to free herself, but unable to. He was just too big and strong. Then Billy drew his hand back and slapped her across the face.
'Shut your mouth, you little bitch!' he yelled as she froze in shock above him. 'You're nothing but a big prick- teaser, and you're going to get what you got coming!' He was raging with fury now, and she could see the passion in his eyes.
The apartment was silent as she waited for his next move. She could feel him shaking beneath her, but she didn't know whether it was from anger or from sexual passion. But it really didn't matter, because now she was
