Temptation...

When Steve started play fighting with his granddaughter Tilly, it was totally innocent. They were on the living room floor, and had been messing around for about ten minutes. Although he had seen her white undies a few times, he tried to keep his thoughts together, until his arms wrapped around the 18 year old, and he became aware of her boobs. He was shocked to start with, because even though he'd watched her grow up, he hadn't imagined her breasts growing so quickly, so firm, so sexual.
Knowing that the house was empty for a good few hours, he decided to see how far he could go, and how far Tilly wanted to go. Her short skirt had ridden up a few times, and he also thought that she had seen him looking, but not stopped him looking, or covering herself up.

He rolled on to his back, and sure enough, Tilly climbed on top of him. She had a smile on her face, that Steve just couldn't place. It was happy, but mischievous, and he willingly let her hold his arms down, as she straddled him.
"Got you now, granda", she cried out.
"Yes darling," he answered, play struggling to get free. "I don't think I can get away now...unless...."
He moved his hips from side to side, as he felt his hardness growing with the pressure of her on top of him. His movements were very slow, and he was sure he could feel her pressing down even more. He watched her face closely, and saw her bite her lip gently. She was grinding her pubic bone
against him, that was certain, so he started to move his hips up and down now.
"Can I tell you something granda?", she asked quietly.
"Of course sugarpie, anything you want".
"Jessica, at school, says that she's seen her daddies willy, when it gets hard, and she says that it gets very big, especially when she strokes it. Does yours? I can feel something very hard inside your jeans now, and was just wondering....."
"She's seen it, and touched it?", Steve gasped.
"Yes, and I think yours might be getting hard now". She knelt up between his legs, and looked down at his bulge. "Can I see it, pleeeease granda", she begged.
"If I show you it, you must promise that you must never, ever tell anyone. Not Jessica, your mum, dad, or anyone, ever. It's our secret, just you and me". He waited for an answer, hardly breathing.
"I promise granda, cross my heart that I won't tell anyone, ever".
He undid his belt, then the button on his jeans. As he unzipped, he watched her face, and her eyes widened as he pushed his shorts down, his manhood springing free, it's purple head looking angry.
"Oh granda", she gasped. "That looks sooo big, can I touch it, please?" she whispered.
"Of course sugar, but can I see underneath your undies first?
"Mummy says that I shouldn't let anyone see there, even though it's nice when I touch myself there".
"You touch yourself there, really?" he asked. "How often?"
"Most nights, really", she replied. "I sort of rub myself there, and have just started pushing two fingers inside myself. Jessica told me what to do, and I think it feels really nice".
Steve caught his breath again, and began wanking as she watched.
"Take your undies off, and let me see", he whispered.
Tilly sat up and slipped her undies off, her legs wide for him to see, and her eyes not leaving Steve's hard cock. His eyes were glued to her open legs, and he could see short, fair hair covering her pussy.
"Give me your hand princess", he said. She knelt beside him and he place her hand around his cock. He had to control himself from exploding immediately as her tiny hand struggled to grip him. "There, that's how to do it", he moaned quietly as he helped her wank him.
"Does it feel nice, granda?", she asked.
"It feels wonderful darling", he smiled. "If you want to feel it better, come and lay on top of me again. You'll feel it nice too".
He took hold of her and pulled her across him, her legs straddling him again, but this time, he could feel her warmth against his hard cock.
Her soft, small body lay against his hardness, her mound rubbing along his shaft, and they both felt how good it was.
"Ohh granda", she whispered, "that feels wonderful, I can feel how hard you are". She smiled as she lay on top of him.
He held her hips and started to move her up and down on his cock, her small legs either side of him, her small pussy spread against him. She could feel the hardness, making her feel like she did when she rubbed herself.
"Jessica says that her daddy's willy spits out lots of white, creamy stuff, when her daddy gets really excited. She says it tastes lovely, and she likes to see it spurt out".
Steve was amazed at what he was hearing. "She's seen it, and even tasted it? How did she taste it?", he asked.
"She told me that she kissed his willy, then sucked it, because he liked it so much, and suddenly, he exploded, and it flooded out. She also said that she thought her daddy was poorly, because he was gasping so much".
"And would you like to do that, darling?" his voice cracked as he asked.
"I would love that, granda, but can we just do this a bit longer, please? I've got a funny feeling in my tummy, and I don't want to stop".
"Mmmmm", moaned Steve. "Ok sugarpie, as long as it feels good for you", and held her hips even tighter.
"Yesss granda, it feels ohhhhhh myyy". She began convulsing, and at first Steve thought something was wrong, then realised that she was cumming. Her groin pressed down harder onto him as she moaned loudly.
Steve was surprised that he hadn't cum too, but knew that would happen soon enough. After a few moments, he asked if she was ok.
"Oh yes granda, that was amazing", she gasped. "Can I kiss this now?", she asked and took hold of his hardness.
Steve nodded, as he watched her move down his body between his thighs. Her small head lowered, and he moved her hair away from her face and saw her kiss his cock head gently. His heart jumped as he felt the soft touch of her tongue, and his tummy rolled as her small hand stroked his hardness again. Her mouth opened and he slid inside. It felt sooo good, and he pushed his cock deeper. She gasped slightly, but her soft mouth made him feel most welcome. She was sucking him gently, and after a few seconds, he could feel himself start his rise to orgasm. Tilly sensed him too, and gripped his shaft tighter as he started to explode, his warm seed shooting into her mouth, but she didn't stop sucking, and gasped again as she began swallowing it. As he finished cumming, she released her grip on his cock, but kept wanking him, watching every last drop exit his hardness, and licking it tenderly.
"Ohhh granda, that was lovely. Made me feel so grown up, so strong, knowing that you were doing that just for me". She kissed his cock again, smiling up at him as she did so.
"And it was ok that I exploded in your mouth?", Steve asked.
"That was the best part", she answered quickly. "I liked the feel of him being very, very hard, and then you got even harder as you exploded. Jessica was right about how it felt, it was fantastic".
"Well sugarpie, what happens now is that I need a few minutes to recover and get hard again, if you want me to, and then we can play again, but only if you really want to".
"Yes please granda", Tilly squealing excitedly.
"So why don't we go to the bedroom, where we can stretch out and get really comfy?"
As he watched her walk towards the bedroom, his cock began to stiffen again.
She turned to face him as they reached the bed, and Steve told her to lay down and get comfy, which she did eagerly. Her short skirt rode up over her thighs, and the sight of her young pubes made him hard again.
"Lay down and let me relax you", he said quietly, his breathing getting shorter, as he began to unbutton her blouse. "If you want me to stop at any time, just say so, darling. I won't be upset, I'll understand".
"I want you to touch me, granda", she whispered. "I want to feel you hard again. It was better than anything I've felt before, so show me how you're going to relax me, please".
She sat up as he helped her off with her blouse, her small breasts cupped perfectly by a white bra, which he unfastened carefully, not wanting to scare her. Her nipples were hard as he threw the bra to the floor, and as she lay back down, they stood to attention. She was liking the adoration, and stretched out in front of him, as he removed his jeans and shorts.
"Can I touch him again, granda?" she asked, reaching for him.
Steve knelt on the bed beside her as she took hold of his erection again, and began wanking him slowly. Her head lowered and she kissed the tip gently, then opening her mouth, started to suck him eagerly, little moans coming from her as her tongue slid up and down his shaft.
He looked down at her small body and his eyes were glued to her soft, downy hair, covering her young pussy. His fingers moved down, stroking her tummy, and when her legs parted for him, his fingers stroked her mound. He searched, and found her tender bud, and she let out a squeal as he rubbed it gently. The sound from her made him start his rise to climax, but he wanted to explode inside her, so he pulled out of her mouth, leaving her to groan aloud.
"Not so quickly sugarpie", he gasped, "I want you to enjoy this time too". As he said this, he moved down the bed to lay beside her, his mouth closing around an erect nipple, his tongue teasing it as he sucked tenderly.
"Ohhhh granda !!!!" she yelled.
"Did I hurt you?" Steve asked quickly.
"Nooooo, just the opposite", she answered, "it's wonderful".
He moved back to her nipple, and continued to suck at it, while his fingers caressed her inner thighs, then her pussy lips, and slowly began to slide a finger inside her. She groaned louder as he did so, so he stopped and said quietly.
"Listen sweetheart, if I start to hurt you, at any time, just say so and I'll stop. I really don't want to give you any sort of pain at all".
She nodded, replying, "I promise that if I feel any pain, I'll let you know, but can I tell you a secret?"

"Go ahead", said Steve, pausing his teasing for a minute.
"Well, a few months ago, I found mums vibrator by accident, and have been using it since. It's almost as big as you are, and it's got two little ears, like a rabbits ears, but it doesn't explode like I want it to, but it makes me feel sooooo good when I push it inside me. It makes my tummy feel funny, and makes me shiver, but I'm not cold. Is that called an orgasm, granda?"
"Yes it is darling", he said smiling. "The vibrator is called a rabbit, because of the ears. Did you put all the rabbit inside yourself?". He knew how big it was, as he'd found it himself, and the thought of her using it made him want to cum immediately.
"Yes I did, it was a bit tight at first, but once it was inside it was lovely, and I was warm and wet, so that helped. When mum and dad were away last weekend, Jessica came and stayed, and we used it on each other. It was easier for her, because she's been letting her dad fuck her. Is it naughty to say fuck, granda?"
Steve's head was spinning as he thought about two young girls using a rabbit on each other, but managed to answer her.
"It's naughty, so don't let your mum and dad hear you saying it, but I think it sounds so lovely, coming from you".
"Do you want to fuck me, granda?" she smiled at him.
"Yes sugarpie, I do, but before I do, I want to kiss you a bit more".
As he said this, he moved further down the bed, easing her legs wider, and began kissing her mound, then lower as his tongue probed. Tilly moaned quietly, then louder, as he found her sensitive bud again.
"Ohhhhhhh granda.....granda.....ohhhhh", she moaned.
Steve opened her pussy lips with his fingers, then began to push one inside her. He was surprised to find her very wet, and his finger entered her quite easily. He thought she would be tight, but if she'd been using her mums rabbit, she'd be ready for anything. He eased two fingers inside and slowly fucked her with them. She was gasping, moaning, groaning aloud and gasping.
As he fucked her with two fngers, and flicked her clit with his tongue, she started shaking, her climax making her shiver madly.
"Yessss granda, yessssssss, ohhhhhh myyyyyyy, yessssssss, don't stop.....mmmmmmmmm", she cried out as her hips rose and fell to the thrust of his fingers.
As she calmed down, he kissed her cheek gently, and she kissing him back, her tongue pushing his tongue from side to side.
"Is it always as nice as this, granda?" she asked.
"Not always, but you should always try and make it special, whoever you're with", he answered with a smile.
A mischievious smile appeared on her lips as she reached for his hardness again.
"Fuck me granda, please fuck me. I want you inside me, now".
He stopped his kissing and rolled on to his back, pulling her onto him. He reached out to his bedside table and took a tube of KY jelly, quickly smearing some into his hand, then massaged some in and around her tender pussy.
"Ooohhh, that's cold", she squealed.
"It will help me slide in and out easier", he replied and putting the tube back, he took hold of his cock and held it upright for Tilly to position herself above it. Her hands were either side of his head as he held her hips above him. As she lowered herself onto him, he could feel her pussy lips covering his cock head. She gasped as the head entered her, and she bit her lip as he slid deeper.
"Ohhh granda", she sighed as he slid in and pulled out again. Slowly, slowly, his cock went further inside, each gentle thrust bringing a quiet moan from Tilly's mouth. As he reached his full depth, she gasped, and he knew he had touched her G spot, and she began to ride him, her hips moving up and down, his cock feeling like it was in a warm, soft, wet box. He had never felt anything like this before, and neither had Tilly. His cock nearly came out of her, she was bouncing up and down so much, and once, she had to push it back inside herself with her little hand. He held her hips firmly, but gently, as he was still unsure if she would cry out with pain at some point, and he didn't want to hurt her. It wasn't long before he began to rise to climax, holding her hips tighter, as she ground herself onto his cock.
"Granda, that's fantastic", she cried, as a shudder passed through her body, "Ohhhhh yessssssss, don't stop, please", she yelled, as he felt his cock explode once more, this time deep inside her.
She collapsed on his body, her face buried into his neck as they both recovered. His cock was still inside her, and she made no effort to let him go, as he felt her pussy muscles gripping him, even though he was limp now.
"That was out of this world, granda, just the best thing that ever happened to me", she whispered in his ear.
