The media still refer to what happened as 'The Event' but as more leaks out we found that it was a series of events. Some super being called Thanos snapped his fingers and wiped out half of life on the planet (Universe if you want to get technical but I'm keeping things local) then a team of super heroes found a way to fix it. I was one of the billions that went missing then came back five years later, I'm nobody special, I'm the only one of four in my house to have vanished though.
I still remember fading, being a Saturday morning I was up early for my daily masturbation ritual before I went swimming, I was a horny 18 year old and knew I'd have trouble staying soft at the sight of all the bikini and swimwear clad girls my age so I'd rub one out before I went. I was naked, knelt over my favorite copy of 'nude girls monthly', the page open on a spreadeagled blonde and jerking my ky coated cock when my left arm went to dust then the rest of me.
Next thing I knew I was back. I was still naked on my bed, my magazine was gone but a girl was there, slim and sexy with amazing breasts, rubbing her clit as a vibrator buzzed away inside her. We both freaked out, I jumped off the bed frantically looking for something to cover myself up, the girl pulled the toy from herself then stared at me wide eyed and her mouth open.
"Ma... Marcus, is that really you?" She said.
My brain, still reeling from the shock, took a second.
"Y... Yes. Clara, but how? What happened, why is my room different, why are you here? Y... you're older?" I said, struggling to keep my eyes off her chest.
She ran up and grabbed me in a tight hug.
"Big brother, you've been gone five years! Here, put this on and clean that lube off your cock, Mom and Dad are going to fucking shit!" She said, handing me a pink silk robe
I washed my face and cock in the bathroom that I shared with Clara when she was 5 years younger than me, I looked into her old room and it was now filled boxes and junk. Clara had put on a t-shirt and shorts.
"Why are you in this room now, what's all that stuff in your room?" I asked.
"Mostly your stuff that Mom didn't want to throw away, this room is bigger."
Clara pulled me by the hand to our lounge, yelling the whole way, Mom and Dad were watching the news, it was going crazy with the people suddenly coming back and some big battle happening in upstate New York. Mom screamed when she seen me, sprang to her feet and hugged me so tight I could barely breath, she had tears running down her face. Dad did too when he joined us.
"You're back, my boy is back." Mom repeated, touching my face.
"What do you remember?" Said Dad.
"I remember fading away then all of a sudden I'm back and everything changed. Has it really been five years?" I replied.
"Yes, after everyone vanished we mourned then tried to move on with our lives, we thought we'd never see you again!" Said Mom, still sobbing.
"Do I have any clothes, this robe really doesn't suit me." I said.
"We should still have a box or two, I'll go grab the boxes." Said Dad.
I sat watching the news while Mom and Dad cleared Clara's old room enough for me to sleep in, it still had an old twin bed that Clara used to sleep on but Dad said he'd get me a new queen since Clara had taken mine with my room. Clara helped me find some clothes but she stayed close to me all the time, if I'd sit down she'd sit facing me, after a few hours I asked her about it.
"I'm sorry, I just had this view of you in my head, I was 14 when you vanished, I idolized you, you were always so nice to me and when you left I was devastated. I just can't believe you're back." She said with a smile.
"Sorry, was just seconds for me, is still hard to get my head round you're older than I am now and not the skinny, dorky little girl I protected from mean kids." I replied.
"I'm not skinny and dorky anymore little brother."
"Oh I noticed."
"You could barely keep your eyes off me." She said smiling.
"Sorry, I couldn't help it." I said, looking down.
"Oh I'm not upset about it."
That night I spent hours online, reading about people coming back. I seemed to have been lucky, some came back to their houses gone, family moved away and worse but I was just thankful to be alive. I rolled to my side in my uncomfortable bed and noticed a little light coming through the wall. Curious as to what it was I got up and looked through and gasped at the sight. Clara was on her bed in the same position she was in when I appeared, naked and fucking herself with a dildo. She was clearly enjoying it, her breasts were swaying with each of her thrusts and she was whimpering in pleasure. At one point I thought she looked at me but I doubted she could see me, I felt my cock get hard but pulled myself away feeling guilty and wrong. It didn't stop me jerking off though, I groaned quietly as my cum splashed over my chest and stomach, cleaned myself up then dozed off to sleep.
Next morning I got up and slowly made my way to breakfast, I could hear talking and decided to hang back to make sure I was hearing right.
"How long do we have to wait, can I take him and tell him after?" Said Clara.
"I think we should wait sweetie, he'll still be dealing with the shock of skipping five years." Said Mom.
"I think he was watching while I was masturbating last night." Said Clara.
"Well who can blame him, I bet you weren't quiet." Said Dad.
I didn't know what to think, I felt myself getting red knowing she knew I was watching her but take me? I made a point of making a noise as I approached the kitchen a second time, they were still eating breakfast.
"Good morning my love, did you sleep okay?" Said Mom, kissing me on the cheek.
"Not really, that mattress is pretty worn out." I replied.
"We'll get you a new one today son, your mom and I will be out shopping all day. Clara will take you clothes shopping, she has my credit card." Said Dad.
"Okay, thank you." I replied.
The stores were chaos, we got enough clothes for me to last a week and decided to order more online but Clara was fun to be around, playful and flirty and always had a smile on her face. When we got home I changed into my shorts and slumped onto the couch, Clara sat facing me, she'd changed into her silk robe.
"Feels good getting comfy huh, thank you again for taking me shopping, I had a nice time." I said.
"I did too, it's really good having you back." She said, softly stroking my arm.
"I uh, we didn't talk about when I came back, I didn't mean to stare at you, I didn't know who you were at first but I shouldn't have looked at you that way."
"Why not?"
"Because I'm your brother and I'm not supposed to."
"About that. Mom said I've to wait but I can't stop thinking about you. Stand up for me."
"What?"
"Trust me okay."
I was a little worried but I did as she asked, I stood up next to the couch and faced her. I started to ask why but before I could say anything she grabbed my shorts and boxers and pulled them to my knees then took my cock into her mouth and started sucking me. I was shocked, she looked up at me as my cock hardened and untied her robe then let it fall off her shoulders. She was naked underneath, her beautiful breasts spilling out once they were free. Her tongue felt amazing and it didn't take her long to get me hard, once I was she stood up, pushed me to sit on the couch, my shorts and boxers falling to my ankles then straddled me, reached down and guided me into her pussy. She took me deep inside her, she was soaking wet already, then she kissed me with furious passion.
"Wh.. what are you doing?" I gasped when she let me up for air.
"Making love to you, sit back and enjoy it, you can cum in me too." She said as she began to ride me.
Her pussy felt amazing, despite my brain screaming 'this is not right' I did as she told me and watched her breasts sway as she fucked me. After a while she increased her pace then gasped in pleasure when she started cumming. I held back as long as I could but she felt too good and I pushed up, groaning in pleasure when I came, spraying my seed deep inside my sister. When we were both spent, she kissed me softly then got up, pulling me to my feet and led me to the shower. We showered in silence, I got hard again from rubbing the soap on her breasts but we dried off then she had me lay on her bed with her.
"When everyone vanished it made those left behind hold on to who was left that much more. Mom and Dad were making love more and were very open about it, when I turned 18 I'd already seen them having sex a few times and well, I wanted to be part of that closeness. Dad took my virginity while Mom held my hand and now I make love with both of them any time we want it. I've been kinda wearing Dad out, that's why I was playing with myself when you appeared but you can help now." She said, gently rubbing her hand on my chest.
"So you've been having sex with Mom and Dad for over a year?" I asked.
"Yes, having sex with women is wonderful. Mmm, you're hard again."
"Well I have a hot naked woman pressing her breasts into me."
"Well you should totally put me on my back and fuck me."
"Can I put you on all fours?"
