Waking the next morning I had many conflicting feelings and thoughts to deal with.

Physically, my bottom was sore and my nightdress was stuck to my skin where Granddad's cum had dried. I had to peel it off my body before I could have a shower and soap the mess away.

Mentally I was very confused. I knew that what had happened was my fault. If I hadn't phoned my Mum, Granddad wouldn't have got cross with me and none of this would have happened. I knew that I loved my Granddad and that he loved me and I told myself that everything would be ok now if I just did as he told me.

I dressed in a white tee shirt and a short denim skirt and headed downstairs with butterflies in my stomach. Granddad looked up from his paper as I entered and held out his arms as he usually did and I gave him a big hug.

Relief flooded through me as I sat gingerly at the table and had my breakfast. Things hadn't changed too much. We talked about what we were going to do and I asked Granddad if we could go to the market?

I was so pleased when he said yes that I hugged him again but as I sat down I winced at the pain in my sore bottom.

"Go to the cupboard over there and get me the tube of white cream,” he told me. Getting up I fetched the cream he wanted. "I'm going to put this on your bum,” he said. "Take your clothes off for me.”

"I can do it myself...” I started to say but one look at Granddad's face made me stop talking and start unbuttoning my skirt.

Pushing the skirt and panties to the floor I stood waiting.

"Bend over the table,” Granddad ordered and as I did I watched him squeeze some cream onto the palm of his hand and walk behind me. I jumped as I felt his hand begin to rub the cold cream into my skin, covering both cheeks of my bottom, the top of my legs and even between my legs on my pussy.

"There that's better,” he said as he finished. "Put your clothes back on.”

I quickly pulled my clothes back in place. The cream felt uncomfortable but soothing at the same time.

Granddad was extra generous at the market, buying me loads of new clothes. He got me some really short skirts, crop-top shirts, knee high boots, push-up bras, thongs and some new very short nightdresses. There was a stall there selling funny outfits for grown ups like nurses uniforms and stuff. Granddad made me wait outside while he went into the tent at the back and I looked at the shoes with really high heels and at a flashing sign that said sex aids, not quite sure of what it meant.

When he came out Granddad had a big bag but wouldn't let me see what he had brought. "I'll show you some of it tonight,” he told me with a funny smile on his face.

On the way home we stopped in a restaurant for lunch and afterwards I had a big ice cream while Granddad drunk his coffee. Looking around I noticed a man who was staring at my legs. He saw me looking and quickly looked away but kept glancing back at my legs.

Granddad noticed me looking uncomfortable. "What's up pet,” he asked? I explained about the man and he glanced around to see who I was talking about. "Well sweetheart. You have to expect that men are going to find you sexy,” he told me with a smile. "There's nothing wrong in letting him have a little look, It'll make his day.”

"Listen I'm going to go to the toilet now,” he said. "When I get to the door I'm going to look around and I want you to open your legs wide apart so that the nice man gets a view all the way up to your underwear.” Seeing my look of dismay Granddad got cross. "If you even think about not doing it I'll make you take your pants off and do it without them.”

Getting up Granddad leant over me. "Remember wide apart and keep them like that till I get back.”

Walking past the man Granddad headed for the toilet door, looked back at me and nodded. Shaking I spread my legs wide apart and looked down at the table as my face burnt in shame.

Glancing up I saw that the man was staring down between my legs and as I watched his hand dropped to his lap and rubbed himself there. As he looked up at me I dropped my eyes back to the table, trying to avoid his gaze.

Sitting there in a busy restaurant with loads of people unaware of what was going on was strange. The man was smiling now as he stared up my skirt and a tingling feeling filled me as I tried hard not to look at him.

Much to my relief Granddad came out of the toilet but it was short-lived when he sat down at the table with the man and started talking. At first the man looked scared but gradually he started smiling and then laughing with Granddad as they talked.

Standing up they both walked over to where I was sitting and Granddad sat down opposite me and motioned to the man to sit next to me.

"Sweetheart, this is Chris,” he told me. "Chris thinks that you are gorgeous and I said that he should come over and tell you himself.”

"You are a darling,” the man said looking directly at me. "You look good enough to eat you're so gorgeous.” The man called Chris was in his forties and was at least 17 stone. He was sweating loads and his face was all red.

"Can I touch her,” he asked Granddad?

Chris and me both turned our eyes to Granddad, me pleading no, silently and Chris with a hungry look as we waited for several long seconds for a decision.

"I'll tell you what Chris,” Granddad finally said. Give me a number where I can reach you and I'll give you a call when I'm ready to share her.

Not really hearing what Granddad said I realised that he wasn't going to let the fat man touch me now and for me that was enough. I saw the man called Chris write something down and pass it to my Granddad and then we were on our feet and leaving.

Safe back in the car Granddad asked me if I had enjoyed teasing Chris and if it had made me tingle between my legs when I had done it. I admitted that it had made me feel tingly there but that I hadn't enjoyed it.

"Don't worry Pet,” he told me laughing. "We'll do it lots more and you'll grow to like it.”

When we got home Granddad had me go upstairs and change into each of my new outfits before coming down and showing him them. I could see from the lump in his trousers that he liked them and seeing him like that both frightened and excited me.

The last outfit was a tiny yellow bikini, which tied in knots at the sides of the briefs and behind my back and neck on the bra part. The material of the bra part only just covered my nipples and the bottoms were just a triangle at the front and string at the back that covered nothing. I could see that Granddad really got excited as I walked up and stood in front of him in this outfit and as I twirled around for him I could see his cock jumping, in his trousers.

"Get me that bag over there and I'll show you the toys I brought for you,” he told me and I quickly fetched the bag he got from the sex aids shop, for him.

First he pulled out a kind of dog collar, with two short chains hanging from it and he got me kneel down in front of him while he strapped it tightly around my neck.

Next were loads of cuffs that had a clip on them and he got me to put one on each of my wrists and one on each arm, just above my elbows.

The next item was like a waistcoat, made up just of straps. We had to work out what went where and Granddad seemed just as confused as me. I finally got it on and did the straps up on the sides. Granddad said it wasn't tight enough but that he would tighten it later for me.

It felt weird having all those straps on me. They went round my waist, above and below my boobs, over my shoulders and even a strap down the front that would go between my legs.

Granddad emptied the remaining items from the bag out onto the table. There were several different sized white things that buzzed when he turned them on, several different sized rubber cocks, some things that looked like weird gags, a riding crop, a cane and a leather whip with a short handle and lots of short strips of leather.

Granddad had to repeat himself because I hadn't heard him speak, I was so scared at what I could see on the table. "Go to the bathroom and get me the Vaseline jelly,” he ordered.

Quickly I went up to the bathroom and found the jelly. I needed to have a pee before I went back down and as I put the bikini bottoms back on afterwards I looked in the full-length mirror.

I looked weird with all of the straps on me. Somehow it looked more naughty than if I had been naked. As I breathed in I could feel them tighten around me and somehow I liked the feeling it gave me.

Taking a final look at myself I rushed back down and handing Granddad the jelly stood waiting in front of him.

"Turn around so I can fasten your hands,” he told me and I turned and knelt, holding my hands behind my back for him. Taking my wrist he twisted it up behind my back and fastened the cuff to the short chain hanging from my collar. It hurt my shoulder, my elbow, my wrist and my neck to have it fastened like that but before I could say anything Granddad had done the same to my other wrist and now he clipped the two cuffs on my wrist together and then with a bit of pulling did the same to the cuffs above my elbows.

Once they were fixed like that they didn't hurt so much although my shoulders ached where they were pulled right back making me push my boobs out and making the straps tight across my chest.

There was a tug and I realised that Granddad had undone the ties on my bikini top and was pulling it out from under the straps. As he tightened the straps one by one I grunted as they dug into me but neither of us said anything until he used his fingers to pull on my breasts, to make sure that they poked through between the straps, as he wanted them.

"You look so sexy like that,” he told me and I must admit I did feel sexy.

Turning me to face him and standing me up, he rubbed his fingers across the front of my bikini bottoms. And along my pussy slit and looked up at me surprised.

"Maybe I won't need that lubricant,” he said as he pulled the bows on either side of my bikini bottoms and let them fall off me then rubbed his finger through my pussy slit and showed me how wet it was.

I felt the heat of shame and embarrassment as he looked at me and I started to cry but Granddad hugged me to him and shushed me.

"It's fine,” he told me. "It's natural to get wet when you're excited and you don't know just how pleased I am that you're enjoying this. I can see that you're scared and that's good but your body tells me that despite being scared you are liking what we are doing and that is great because I plan to do lots more with you now we have started.”

As I stood there I felt Granddad's hands go up the inside of my legs. One held my pussy lips open while the fingers of the other started rubbing up and down my pussy slit and just inside. It was much nicer than when I did it to myself and soon I could feel my legs begin to turn to jelly as he brought me close to my first cum.

Hearing a buzzing I looked down and Granddad smiled at me as he rubbed one of the white things up and down my pussy. I jumped as it touched me and heard myself gasp.

"Nice isn't it?” Granddad asked and pushed it against me again.

All I could do was nod as I started to cum and he had to catch me as I fell across his lap pushing the thing further inside me as I did. It felt wonderful as I lay there with it slightly inside me, my body jerking as I continued to cum.

Feeling Granddad tightening the strap between my legs I looked down. The strap had slits in it and I could see that he had pushed the white thing through one of them so that the strap held it in place in my pussy. As he tightened the strap even more I felt it move even further inside me and gasped, as it seemed to vibrate throughout my body.

Now Granddad had both of his hands free and me laid across his lap, he started playing with me. His hands travelled all over my body ending up on my boobs and my nipples where he pinched and squeezed them. The pain was enough to stop me cumming as it distracted me from the feelings between my legs and I teetered on the edge between the pain and the pleasure for what seemed like ages until Granddad finally reached down and pushed the vibrating thing further inside me as he let me have my cum.

This time he turned it off after I had finished and I lay there on his lap, feeling him gently stroking me as I dropped off to sleep.

When I woke up, it was to find Granddad playing with my nipples and tugging on them.

"Hi Sweetheart,” he said. "How about you making me cum now?”

Nodding yes I felt him ease me to the floor between his legs. I could still feel the vibrator thing between the lips of my pussy but it wasn't doing anything.

Granddad undid his trousers and pulled them and his underwear down a little, letting his cock jump free and putting his hand around my head he pulled me forward so that my lips touched against it making me pull my head back.

"Well you can't use your hands this time, tied like that, can you?” asked Granddad pulling my head back down to touch his cock again.

His cock was wet and slimy and it was with shock that I realised that he expected me to use my mouth on it. I'd heard at school that some of the older girls gave blowjobs to their boyfriends and my friends and me had talked about it but we had all agreed that the idea was gross.

Granddad hadn't said anything, he was just sitting there waiting but I knew that I didn't really have a choice. Strapped up like I was he could make me do anything he wanted and I was in no position to fight. Also I knew from last night that if I made him cross it was likely to be more painful for me.

Sticking out my tongue I licked the head of his cock and tasted the wet stuff on it. It tasted salty but not nasty so I started licking it all over, hearing Granddad groan in response.

It made me feel good to be able to make Granddad groan like that and so I opened my mouth and took the head of his cock inside, sucking and licking on it for him.

"Oh god yes,” he cried out. "That is wonderful Sweetheart.”

As I sucked and licked on him I felt Granddad's hand on the back of my head pulling my head onto his cock and then releasing it so that I could back off. I realised what he wanted and bobbed my head up and down letting his cock go deeper into my mouth as I did.

Granddad had one hand on my shoulder, steadying me and the other was playing with my breast. It wasn't easy bobbing my head up and down as the collar around my neck dug in every time I bobbed down and my shoulders hurt from the way my arms were held up my back.

"Don't stop,” he warned me. "I'm going to cum and I want you to swallow every drop.”

When we talked at school about blowjobs we had heard about spit or swallow and even though I had decided then and there that I'd never have to choose because I'd never let a boy put his willy in my mouth, I realised now that I wasn't going to get to choose anyway.

The hand on my shoulder moved back up behind my head and started pulling me harder onto Granddad's cock, sometimes making me choke as it went too far back in my mouth. The fingers on my nipple started pinching and twisting, making me yell around Granddad's cock in my mouth as I felt the first spurt of his cum. I choked and coughed on it as spurt after spurt of cum filled my mouth.

Swallowing as quickly as I could I finally cleared my mouth of cum and sucked on Granddad's cock as it got soft in my mouth. His cum had tasted musty and salty but wasn't gross like I had expected.

"Oh god Sweetheart, that was fantastic,” he said. "I love you so much.”

I felt myself fill up with love for Granddad and pride that I could make him happy like this.

That night I slept in his bed for the first time, cuddled up against him and feeling his strong arms, protectively around me.
