It was Prom and I was, to use a cliché, the Belle of the Ball. I had spent a week's allowance on having my hair done and another week's on my nails, though strictly speaking Grandma had subsidised both as an additional treat. The main treat, of course, was the dress -- a dark blue creation which went down to the floor, but with a cut that meant by sexy legs were continually being revealed for quick flashes as I walked, and with a low enough cut at the other end that whilst my large tits were in no danger of popping out, they were far from being fully covered.
Despite being asked by several guys I'd not accepted a date from any of them, instead hanging with my girl friends; even if many had their boyfriends with them I was seldom alone for more than a minute or two, as eighteen year old seniors, who had known each other all the way from elementary school, we stuck together. And to be fair, even if wasn't absolutely in, I wasn't totally out either and so when a guy came and asked for a dance I was happy to oblige as long as they knew that was all they were getting (a quick peek down my cleavage didn't really count as going any further, and as we were about to leave school for the last time it hardly mattered if the President of the Math Club got a bit more of an eyeful than he had when we were sitting in class). One or two tried to go a little further (not the Math Club guy who was a perfect gentleman and would probably die a virgin), but I easily slapped them down, my ass only gets groped when I want it to.
And I did want it to be played and kneaded, to feel firm fingers pressing into my round rump, digging into the flesh and squeezing it, before jiggling it up and down like a plaything. I took a sip of my non-alcoholic cocktail and subtly glanced round the room. There were plenty of teenagers, dancing and having fun, certainly a few of the girls, at another time, I could have been interested in, especially the soccer team's captain who managed to combine the hottest body in the school with a toothpaste ad smile and enough brains to get the top college of her choice. Clustering at the edges of the room like bats afraid of going onto the dance floor's light, were the teachers and volunteer chaperones, (as if without them we'd all be having a no-holds orgy in the assembly hall). I'm not going to deny that some of the female teachers had figured in my fantasies, and I'd certainly played with myself at night imaging Mrs Walker correcting my homework before rewarding me for my correct answers with a hard pussy licking over her desk.
But amongst the various volunteer chaperones, standing and having stilted conversations with the teachers they barely knew was someone who I wanted to grope my ass and more, my lover, my Grandma. She seemed to sense I was looking at her as she momentarily retreated from the group she was in to turn her head in my direction. She was far enough across the room and in the gloom away from the lights that I couldn't gaze into her eyes or even see much more than a pale pink face, expressionless and blurry. It didn't matter, it was enough that she was there and looking at me, and, I was sure, desiring me as I desired her.
My friend Shawna misread the look, which was lucky as she'd have freaked if she'd really known what I was thinking, "It's a bit of a pain your Grandma's here, I bet when your Mom had to bail you thought you'd have a wild evening."
"I'm a good girl," I said with a grin which suggested both Shawna and I might think I wasn't. Then cheekily, knowing that Shawna would misinterpret and think I was joking, "Anyway me and Gran will have a wild time later."
"What? A couple of glasses of milk and some cookies, before a kiss on the cheek and you heading to bed," Shawna laughed, little knowing how close she was getting, though the kiss would be a lot less chaste than she imagined and I wouldn't be in bed alone (I also wasn't sure about the milk and cookies).
I didn't correct her, and moved the conversation on. Even if she and the rest of my friends would never have guessed the real reason I kept glancing at my Gran they might instead think it was because I was bored or distracted with their company and that's not something a girl should do to her friends, so I moved back to the conversation, "I was just worried she'd be out of her element, it's not Gran's thing - anyway what's this about Becky and the college guy? Beck's spill..."
The conversation quickly moved away from Gran and onto my friend Becky's semi-drunken make out with a college guy the week before. However, whenever I could I quickly stole glances at Gran. She looked as sexy as fuck to my mind, rocking even a conservative trouser suit with a white blouse and I couldn't wait to get it off her as she got my dress off me. But that would need to wait. I continued to talk to my friends, agree to dances with guys who asked and sipped the non-alcoholic fruit cocktails which well meaning waiters kept placing in front of me.
I'm not saying I didn't enjoy myself, but it was definitely the enjoyment of Christmas Eve or the night before your birthday when you're eagerly anticipating the next day and no matter how much fun you're having with your friends, you know something better is about to come. I wasn't too disappointed when the lights came on and the Principal came up on stage to say a few words of wisdom before telling us to leave the building. I said goodbye to my friends, some of who were going onto a party, together with at least one who had booked a hotel room with her boyfriend where she was planning to lose her anal virginity. I'd made out I couldn't as we were having a family treat away and I needed to be up at the crack of dawn. It wasn't quite true, I was going to a hotel, but it was tonight and, I too was planning on losing my butt cherry to Gran that night -- which I guess technically meant it did count as a family treat.
I wasn't waiting long before Gran drove to the front of the school in her new 4x4. I lifted the hem of my dress and got in. Gran looked hungrily as I got in, "You look ravishing," she said. She had already told me that before we left my house, but I wasn't against being told again. Because we were still in school grounds and there were people around limited herself to kissing my cheek. She drew back. "I can't wait to fuck you," she murmured sexily.
"I can't wait for you to fuck me," I giggled, my pussy already starting to tingle at the thought of Grandma pounding me with her strap-on. "You're looking hot as well."
I had already said that as well. Gran smiled, "I had to dress formally for my girl's prom night. Speaking of which..." she reached into the glove box and pulled out the corsage she had bought me earlier, presenting it to me when she arrived at my house. I had worn it for the pictures Mom had taken of me in my Prom Dress, my Gran date beside me, hands round each other's waists, and then as she drove us to the Prom itself. On arrival I had taken it off, as we both agreed that wearing something that was traditionally bought for a girl by the person taking her, might raise a lot of questions which I'd have to lie about.
I slipped the corsage on, it felt as if the dancing in the middle had been an interlude and the real date was now just continuing. "How long until we get to the hotel?" I asked as Gran turned the key in the ignition.
"Just under an hour," Gran replied, "I guess we'll just have to practice the art of conversation."
I grinned, talking to Gran was easy, she was such a great talker, both entertaining in what she had to say and interested in my replies, always making sure the chat didn't drift into areas of which I'd no interest, like politics or business, whilst equally not sticking to the subjects I discussed all the time with my friends, elevating it above gossip and fashion. The hour flew by.
