The fun and games started shortly after my great grandpa moved into the house next door to me. I was just eighteen at the time and still lived at home with Mum and Dad. Great Grandpa Jack was my mother's grandpa. He was seventy-five years old and a real nice guy.
It was shortly after Grandpa Jack's wife died that Mum decided he should move in next door so we could keep an eye on him and look after him. He had been pretty depressed and lonely since his wife died. So as soon as the home next door to us became available, he sold up his old property and moved in next door to us.
To begin with, he spent most of his time in his garden or pottering around in his shed. Problem was, this gave him an unobstructed view into my bedroom and front room. On a few occasions, I caught him looking up into my windows from his garden shed. I made a point of catching his eye, thinking that might embarrass him into looking away. Instead, he would wave cheerfully at me and just keep on looking.
After a few weeks, I realised that, since his house shares a wall with mine (blooming terraced houses!), he could hear a lot of what goes on in my house. Including when my shower is running. I noticed that whenever I finished a shower and went into my bedroom, there he was, in his garden, looking right into my bedroom. I don't like curtains. I like the sun on my skin and walking around naked in the house quite a lot. Besides, I felt like it was just letting him win if I hid behind curtains.
One morning I was feeling daring so decided to give Great Grandpa Jack a little treat. I did my morning exercises naked, in front of the window while he was ogling me from his garden shed. I alternated jogging on the spot with long stretches. Normally, tits as big as mine need to be held down with a pretty sturdy sports bra, but since I was in the privacy of my own home, I didn't mind a bit of a titty bouncing. I kind of liked it, as a matter of fact.
It seems that Grandpa Jack did as well. I could see his silhouette through the window of his shed as I stretched my leg over me head to loosen my hamstrings (free cunt shot) or jumped up and down to limber up (breasts bouncing wildly). I would also bend at the waist to touch my toes and warm-up my back muscles (nice long view of my rounded ass, and exposed cunt). I could never tell, but I imagined him watching me from his little shed, moaning quietly so no-one could hear, tugging feverishly at his wizened old cock.
One particularly warm morning, I sat out in my garden drinking my morning coffee, wearing just a bathrobe. As soon as I sat down on a garden chair, Grandpa Jack's bald, liver-spotted head popped over the garden fence. He's a keen gardener, so when I asked for some advice, he stepped over the fence between our gardens and got on his knees to show me which of the weird green things were weeds.
His voice shook as he tried to sound casual, telling me stuff I really wasn't interested in about plants and trees and shit. He was on his knees in front of me, and I could see he was trying to see up my robe while he talked. I slowly let my thighs relax, spreading my knees apart. His voice really started to shake and then finally stopped. He just sat there, on his knees, staring at my gaping pussy. I finished my coffee and cleared my throat. This seemed to snap him out of his trance and he looked up at my grinning face. I got up and tossed a 'catch you later' over my shoulder as I went into my house.
From then on, I knew he was an old perv who was desperate for a shag.
Of course, he pretty much saw me whenever he had a mind to peer into my house from his garden. But I didn't mind giving the old git a few thrills every now and then. I knew it made him happy and, to be honest, it gave me quite a thrill knowing my Grandpa was perving over my young body. I pretty much saw him as tame. As far as I was concerned, he was my Grandpa, so there was no way he'd try to touch me up or anything like that. But how wrong I was.
My parents were away for the week, on their 20th wedding anniversary. I had the place all to myself. The first night they were away, I was lying in bed reading a book and wearing a lace nightgown when I heard the front door open. I thought my parents had come back early.
"Mum? Dad?" I called out nervously.
My breath caught in my throat when I noticed a silhouetted figure standing at my bedroom doorway shrouded in darkness. At first, I couldn't make out who it was. Though judging by the shortness of the figure and the rotund and hunched over shape of the body, outlined with a baldhead, I knew it had to be Great Grandpa Jack.
He stepped into my room, into the light, and I gasped in shock at what I saw. He was naked except for his string vest and shabby white socks, his body covered in a thick mat of wiry grey hair.
"Do you mind if I join you in bed, sweetheart?" he asked kindly.
I was scared shitless, frozen to the spot, yet the thought of Grandpa touching my body appealed to me, made me moist between the legs. I recalled all the times he had leered at my naked body and wondered what it would feel like to have his wrinkly hands touch me. I wanted to know what skin-to-skin contact would feel like, rubbing our sweaty bodies against each other's in a frenzy of excitement.
