My brother and I were lying on parallel sofas watching TV. "I don't get it, Liv, why don't you just bid $1 if going over means elimination?" He asked.
"I don't think you're eliminated." I replied in a quiet voice. Mark and I were close, but me being younger, I was shy. Mark was muscular, tall (6') and attractive, and that's from a younger sister's perspective! My friends all agreed they'd fuck him given the chance. He was popular and looked nothing like me. As a twin it made me jealous how popular he was.
I on the other hand, while hot, I was unpopular. There was no shortage of lesbian rumours even though I denied them. I had a great bubble butt, 34D boobs, I was short (5'2"), my genetics made it so that I had a shortage of body hair, except for pubes, which I just shaved. I had black hipster style lenses (they were prescription) and ginger/blonde hair which I dyed purple.
"Y'know, your purple hair is growing on me." Mark and I being twins in August left us both 18 in High School, a lot of girls tried to sleep with Mark, but no-one even tried to ask me out. Mark's phone buzzed. "It's Mom. She says were going on holiday to Spain at the end of the school year!!" Our mother slept with a single guy at 18 years ago and got pregnant with twins. Us.
The day came for us to go to Spain. I wore a bikini, but I put on tiny jean shorts (which exposed the bottom of my ass) to cover up my lower half. On the way there we fought for the front seat, our mom moved us to the back seat and just filled the front with luggage.
I quickly got a cramp so I sat on Mark's lap and stretched out along the back seat. Mom didn't pay attention to anything except the road, she didn't notice Matt when, out of the blue, he stuck his face in my cleavage, I gasped loudly as Mark licked at my tits. I pulled his face out and moved to the other side of the car, noticing a bulge in his shorts. We got on the plane shortly after.
We rented a house just by the beach. I quickly got changed out of my shorts and went to sunbathe on the beach.
On my way back I saw Mark in the window completely naked with his cock out, erect, all 10" poking out. I raced back to cover him up then I came across him lying on one bed in our shared room.
"Hey!" He nonchalantly commented, as though he didn't have a 10" erection poking up.
"Wait, we're sharing a room, but there's one bed?"
"Sharing a bed." He put down his phone. "Come here, we'll talk if you want"
"What, about how you tried to motorboat me? How you're flashing yourself out the window?" I walked over to him and closed the curtains
"Mom's gone, I just want to talk!" He pinched at my fabric on my bikini bottoms, pulling it out of my ass crack. I sat down on the bed, suspicious. "Lie on top of me."
"What!? NO!"
"At least sit on my legs." I obeyed, sitting on his knees. He made a small 'come here' gesture, so I did until I was pressed up against his cock. It was warm and solid, but strangely smooth I could tell from it touching my stomach.
He suddenly sat up and kissed me. Mark being over half a foot taller than me helped him still overpower me. His tongue shot into my mouth, then slowly retracted as I subconsciously sucked on it, my eyes closed in passion. Next my tongue entered his mouth. One of his hands ran up the inside of my thigh while the other fondled my breast through my bikini.
5 seconds later I suddenly snapped out of it and leaped off him. "Jesus, Mark!! That should never happen again!! I'm going to get a shower, doors LOCKED and you're going to take care of that." I pointed at his large erection.
I wandered into the en suet bathroom I went into the shower, and I'll admit, Mark's dick did feature a part of my masturbation. Being a lonely virgin left me horny for any dick I could think of.
Once I got out of the shower, Mark was gone, so I wrapped a towel around myself and lay down on my stomach on the bed and went on my phone.
An hour had passed when Mark came back with a plastic bag. He gave it to me and to my horror I found anal beads, lube, glass buttplugs, a cat tail buttplug, a glass dildo, condoms, Viagra, birth control pills, a pregnancy test and a remote vibrator, about 2" long with a clip for panties. "What the shit is all of this??!" At that Mark took off my towel to demonstrate. My arms shot out to cover my private areas.
"Well the pregnancy tests, pills and condoms are obvious, the buttplugs and anal beads go up your ass with lube while the dildo and remote vibrator go into your pussy."
Mark, I'm going to fucking kill you!" For a shy girl like me, that was a rare outburst. I put on my bikini, covering my pussy and turning around so he didn't see my nipples, though Mark may have got a good shot of my asshole.
That evening, after supper, Mark spooned me in bed, then I felt something prod me. I slept in a pair of pink panties and a shirt, but Mark got in showing me his bare cock, I had a good idea of what it was.
A hand moved my panties out the way and then another covered what was underneath with a thick layer of lube, me being a horny virgin I didn't protest at all. The first hand reached under my shirt and played with my tit and nipple while a hot object poked my asshole. "Mark, if we're going to do this then it's not going to be under some duvet while I sleep." I whispered.
I whipped off the sheets and turned to Mark, holding his lubed dick in one hand and my tit in the other. I took off my shirt, exposing bare, brown nippled boobs, then my panties, stuck against my moist pussy lips. Now that we were both naked I kissed him. My tongue in his mouth, then vice versa.
He rubbed me up and down, my waist up to my tits, he then stopped kissing me and he went down to suckle on my breast, licking my nipple, sucking on everything he could. I then went on my knees and dropped my head to the mattress. Next I spread my cheeks, exposing my good looking, but wet pussy along with my lube covered asshole.
Mark put himself behind me and covered my ass with more lube, putting in fingers to make it even slicker. Next I know, my big brother is shoving his cock against my asshole.
Mark put in a little more pressure then it slipped in. It was uncomfortable, but really good. Mark then began to doggy style hump my ass, I reached under myself and played with my clit, I rarely even played with myself before now, there was even lube spilling down my leg. I was rocked back and forth, being filled by this new feeling.
