Lot of fantasy in this one. Time travel, portals and fantasy that isn't based on anything real! All over 18, no anal, all straight sex.
My lightsaber buzzed as I waited for her to attack. She tried to catch me by surprise but her tell, her eyes showing me right where she was going to swing then her step to the right let me counter it easily. I parried her blade, spun and delivered what would be a killing blow to her neck as she fell to the grass.
"I don't even know why I try with you. Four years on the fencing team, two, no, three different martial art classes a week and on top of that you still go play lightsaber fights with your fellow nerds," said my sister, Gina as I helped her up.
"You're the one who challenged me, sis," I said with a laugh.
"Well, I'm better than Lucy and she managed to beat you."
"No, I let her win, she is cute and I like her smile."
"You like her tits, be honest."
"I was trying not to be crude, but yes, she is very well blessed."
"Push up bras, bro, you're so easily distracted."
"I am not."
Gina lifted up her sweater and flashed her breasts at me. She knew I was a breast man and hers were really nice. It was a perfect distraction of course. She gave me two rapid strikes with her saber then claimed victory.
"Totally doesn't count," I said as she laughed.
"Does too! I got your neck then your chest, totally fucked," she replied, grinning.
"Yea, flashing forbidden fruit to distract me, so not cool."
"Who said they're forbidden, we shared a womb, we could share a bed."
"What?"
Another distraction, she smacked me in the balls with her saber then ran into the house squealing as I gave chase. I caught her in the lounge and pinned her to the couch as I tickled her. Her squealing and laughing got us some attention.
"Will the pair of you please knock it off. I am trying to figure out these equations and you are very distracting," said Dad.
"Sorry, Sir," said Gina.
"If you could both clean up for dinner, the food should almost be ready," said Mom.
Gina and I lived at home with our scientist parents. We had moved to England in the countryside as they called it, on an old estate that had been in our Mom's family for generations. When her aunt had passed away, it left my Mom as the only living heir and despite us being American, they packed up everything and moved us over with them. Gina and I had made a few friends but our entertainment was pretty much each other, erotica that we found online and my lightsaber fighting. I had a few, combat hardened blades that were made to fight and spar with and had all the cool sound effects. Mom and Dad had me in martial arts since I was young, they saw it as a great way to direct my high energy and they were right. I held black belts in 3 different forms and was working on combining what I knew. I'd taught a few classes before we moved and I enjoyed it. I used to do lightsaber combat demos when I still lived in the US too but I loved it and it was a fun outlet for me. Gina picked up some of it from me but she wasn't a fighter. She was mellow to my chaos and on nights where our parents would be up to 2am writing equations on their chalk boards, we'd cuddle together and browse erotic stories. We'd take turns and would pick one that we hoped would make the other excited. I could tell when she was, her nipples would be like bullets and her neck would go red. For me, it was always obvious. A lot of the time, we'd both lose and we'd call a draw but at 25 and isolated from any potential partners, we'd explore with each other in ways most would frown upon. We started off just making out but that soon turned to groping then eventually, mutual masturbation. We made a pact to go no further than that though and we just enjoyed the sexual tension between each other.
Our parents seemed pretty distracted at dinner too, we knew they were working on something pretty big but we didn't find out just how big until later. That night after we'd gone to bed, Gina came into my room and got into bed with me. She was shaking and didn't seem to care that I slept naked.
"I... I think my room is haunted, Marcus," she said to me.
"Wh.. What, why are you shaking, sis," I replied, I had just drifted off.
"H.. He seemed so real, he... he tried to grab me."
I held Gina close to me, she was shaking pretty hard and was terrified.
"Probably just a bad dream, sis, you're okay. Let me put shorts on and you can sleep in here," I said.
I pulled on a pair of boxers and quickly got back into bed. I spooned Gina until she stopped shaking then she rolled over and cuddled into me. We both fell asleep soon after. When I woke up, I was spooning her again with one hand cupping her breast. I was hard too and my erection was sitting in the crease of her ass. She held me in place when I tried to pull away.
"I was having the most wonderful dreams, don't you dare pull away," she said.
"Explains my dreams too, should I take my hand away?" I replied.
"No, it feels nice."
We only separated when the need to pee took over, we both went in my bathroom then quickly got back into bed together. She cuddled close to me with her head on my chest.
"I could lay here all day," she said, softly.
"Not sure I could, you have me throbbing, sis," I replied.
"Want me to take care of it for you, stroke it nice and slow while you stare at my boobs?"
"Now there's a picture of a wonderful day."
"So, I've been thinking a lot and I think I want to break our pact. I'm a virgin at 25, Marcus. I'm in a place where we know one girl our own age who I know would fuck your brains out if you gave her half a chance but I want you in ways we're not supposed to. I don't care, I want to give myself to you."
"I think I'd want that too, Gina."
"Then, on Friday, you and I will make love, I want you."
"Oh, here you are. Gina, can you make breakfast my love, I have to help your Dad," said Mom, not bothering to knock.
"Uh, sure," she replied.
Mom left just as quick as she came in.
"Well, that answers that. She didn't bat an eye to the fact that you're laying here with a boner and I'm all over you," laughed Gina.
"We could have been fucking and I'm sure we'd have got the same, distracted look we always get," I replied.
"I'm going to make breakfast, thank you for cuddling me last night, I really was freaked out."
"You're welcome."
"A parting gift."
Gina lowered the straps to her nightgown and showed me her breasts. I got a good 5 seconds to gaze then she smiled at me then left.
"Cold shower it is," I said to myself.
Mom and Dad were in deep conversation when they came to breakfast. They were looking at a notepad together and barely looked at us. They both ate while barely acknowledging us being there. Dad finished, said a brief 'thanks Gina' then left. Mom finally looked at us.
