It's funny how life works sometimes. I never would have thought that after a big fight with my mother I'd be having such great sex.
It all started one night when my Grandpa was staying with me and mum for a week. You see, I'm pretty proud of my body and I dress in a way that highlights it. This one night in question, I was wearing a pretty damn short skirt, a tight midriff top, a jacket over the top and some high heels. Mum has always hated the way I dress, and was especially on my case that night because she hadn't seen her dad in a few months and she always makes a huge deal out of trying to impress him with how great a person she thinks she is. Usually Grandpa isn't impressed by her fake efforts and does his best to shut her out, really.
So anyway, over dinner mum started yelling at me about dressing like a slut and asking me how I could dress like that in front of my grandfather. Bla bla bla. So I yelled back, calling her a bitch and saying how much I hate her; you know, the usual argument stuff. It didn't take long before she sent me to my room for the night, even though I'm 20 fucking years old. Grandpa looked pretty uncomfortable throughout the whole thing and I admit I was pretty surprised when I heard him tell mum that my clothing wasn't that bad after I left the table.
In my room, it was pretty obvious I wasn't going to talk to mum for the rest of the day, so I got changed into my pyjamas. For me, that consists of a pair of my neon boyshort-style panties and a button-up top, of which I really only bother doing up one or two buttons at the most. As I was getting changed, I looked at myself in the mirror. Some people might say I'm vain, but I'm really just happy with my body. I looked contently at my slim body, standing 5'8", with my light brown hair just reaching to my shoulders, down to my perky B cup breasts with their light pink nipples starting to get hard in the autumn air. My eyes continued past to my tight stomach to my perfectly hair-free pussy, just recently waxed. I twisted my body slightly and looked as I gently rubbed my ass cheeks. Yeah, you can't really blame me for wearing clothes that show my body off now, can you? I was once told that even wearing clothes at all could be considered a crime against nature.
In my PJs and still fuming at 11pm, I passed the time by texting friends and attempting to read a book I'd already read five times before. I decided to just give up and try to sleep, since I knew mum was still up and I just wanted to stay the hell away from her. Naturally, I couldn't sleep and was still awake at 1:30 when Grandpa came into my room, scaring the hell out of me. He flicked the light on and dimmed it so it wasn't so blinding.
"Jesus, Grandpa, I don't know what it was like in your day, but you just can't burst into a girl's room without knocking!"
"All right, calm down Emily." Grandpa came in and knelt beside the bed, while I lay there under the nice warm covers. "I just came in to tell you that I'm on your side. Your mother was completely out of line talking to you like that."
"Really?" I'd always thought of my Grandpa as pretty cool, but still conservative. "I can't say I'm not surprised, but I'm glad you think she's a bitch."
"I'm her dad, so I can't exactly agree with you on that one, but she has always been like that, more or less. But as I was saying, I don't find anything objectionable about the way you dress. It seems you're a very confident girl and you show that through your clothing." I have to admit, for a 72-year-old guy, Grandpa can be pretty perceptive at times.
"Wow, you pretty much hit the nail on the head there. I wish that bitch would get a clue and realise that's why I dress the way I do. Fuck, I wish there was a way I could get back at her for being such a shitty parent... Um, sorry about the language, Grandpa."
"Actually, Emily, I came up with an idea that will let you do exactly that." When I asked why Grandpa was so insistent that I get even with mum, he whispered, "Just between us, I always ha...she was always my least favourite kid."
I couldn't help but giggle in surprise at that. When I stopped laughing, I asked him what his revenge plan was. In response, he gently pulled the covers off me, leaving me completely uncovered apart from my legs. Grandpa then reached out his hand and grabbed my crotch, and caressed my vagina through my panties. To say I was shocked is an understatement. I know it's clichΓ© to say this, but I was too shocked to even move, so he kept fondling me as he leaned over to whisper, "If you sleep with me, your mother will be so angry and powerless to do anything to control you anymore." Still rubbing my pussy through my panties, his other hand unbuttoned my pyjama top and he started playing with my nipples. "The louder we are, the more likely she'll know exactly what we're doing in here." Grandpa was right. My room and mum's room are right across from each other, and sound would easily carry.
I must be a pretty fucked up girl, because the thought of my mum hearing her daughter fucking her own grandfather as revenge for years of awful parenting was way too enticing to pass up. I knew I'd have to fake how much I was enjoying fucking Grandpa in order to be heard, but that was a small price to pay. I started to feel myself getting wet against his hand. And then I had an idea.
"What if we tape it, Grandpa? And make sure she gets a copy?" He was still playing with me, and as I explained my idea, I started thrusting my hips against his strong hand, indicating my enthusiasm. I'm sure by now the moisture had seeped through the fabric of my panties. Naturally, Grandpa thought it was a great idea. He leant over and kissed me very passionately on the mouth, and I met his lips with my open mouth. Our tongues danced with each other as our mouths opened wide in a kiss that was equal parts sexy, exciting and strange.
"May I climb in with you, Emily?" Always the gentleman, my Grandpa.
"You take those clothes off and you've got yourself a deal," I smiled at him. As he was unbuttoning his own pyjama top, a question popped into my mind. "Say, you don't need to, like, take anything, do you? You know, some Viagra or something?"
Grandpa's answer was to take off his pants, revealing a pretty impressive 8-inch circumcised erection. As I gazed on my grandfather's naked body for the first time, I was struck by just how handsome he was. He used to play sports in his youth, but all the muscle he developed back then has looking since left him, and now he's getting a bit chubby. He's about 5'10" tall with lovely green eyes, and has lost most of his silver hair now. He keeps it short and conservative, no combover. Yes, for an old man, he certainly is sexy. Well, I think so, anyway. As he climbed into my bed, I sat up and took off my own top and panties, then leaned over and retrieved my phone. He ran his warm hands over my ass cheeks while I set the phone's camera to automatic video mode and placed it on my bookcase, which is just within reach of my bed. I hoped the light was bright enough for the camera to pick up everything that was going on.
Grandpa seemed happy to keep playing with my ass cheeks, so I remained lying on my stomach and started stroking his lovely cock. He moaned with pleasure as my hand gripped it and slowly moved up and down, marvelling at just how hard he was for an old guy. To my surprise, I was genuinely turned on; I could feel my pussy was making a small wet patch on the sheets where I was laying.
"Mmmmm, Grandpa, it's so hard, and big!"
