Deep Anal For Sister

Disclaimer: This is a 100% true story. I am now 20 years old and my brother and I both sat down one day and decided to write the story of our first time together. Everything in this story happened the way I wrote it. I tried to add as much detail to the story so you could picture what was going on at every moment. Enjoy.



Well, it all started when I was 13 and my brother was 21.

I was at his house for a week during summer so I could swim in his pool and stuff.

At the time I didn’t know the first thing about sex, other than what the other girls at school sort of

talked about.

Anyway, one day I was in my brother’s back yard trying to tan in a one piece bathing suit my mom

bought me, she wouldn’t let me wear 2 piece suits yet because she said I was too young.

My brother came out of the house and started to heat up the grill to make some burgers for us.

I was bored just laying there and at the time my favorite game to play at school was truth or dare, just

because we would do gross dares that nobody ever followed through on, and pretty innocent truths.

I asked my brother if he wanted to play truth or dare, and he said, “only if you actually do the dares, I

played that when i was a kid and nobody ever did.”

I said, “well that’s the rules, if you do the dares I’ll do them too” and he said, “ok lets play while the grill

heats up”

For the first couple rounds we just did truth, and asked innocent things such as have you ever kissed

anybody and do you like certain people.

My brother noticed I was starting to get really red from the sun and said I would get horrible tan lines

wearing a 1 piece suit and I should tan naked.

I said, “I’m not gona get naked around you, you’re my brother, lets just keep playing”

A couple more rounds of truth or dare went by then on his turn to ask I chose dare. Right away he said,

“I dare you to tan nude” I said no way, but then he said, “you agreed to do the dares, if you don’t do it I

win”

I knew he was right, plus I was only 13 and I didn’t want to lose a precious game of truth or dare, so I

said fine and got up and stripped my suit off and layed back down.

Since he made me do this I was gona try to give him what I thought was a gross dare so that he would

lose and I could get my revenge. On my turn I asked him truth or dare and he chose dare. The grossest thing I could come up with was “lick my butt” and, to my surprise, he quickly said, “ok roll over,” so I

rolled over onto my stomach. He licked my butt cheek but I said, “no, not my butt cheek, my butt

hole!” I expected him to say no way but again, to my surprise he just dived right in and gave my ass

hole a long lick. I was shocked at how good it felt, I’d never felt anything like that before and it made

me kind of horny. I said, “ewwww you perv, you licked my butthole, wasn’t that gross?” and he

responded “no, you were in the pool all day, it’s completely clean.”

It was was his turn again and I chose truth. He asked me if it felt good when he licked my ass, I shyly

told him it felt super good actually. At the time you have to remember that I was 13 years old and I had

no idea there was anything sexual about it. It was my turn again and he chose dare. I had always

wanted to see a guys dick but I was embarrassed to ask, but I just spit it out that I wanted to see his

dick. With no hesitation he pulled down his pants and started rubbing his dick to get a boner. His dick

was pretty big, I figured out later that it’s 7 1/2 inches and it’s also pretty thick. I just stared at it and

then he put it back in his pants about as quick as he took it out.

It was once again his again and I chose dare. He dared me to put a finger up my ass. I asked him if that

would hurt, but he said, “no, it will feel even better than when I licked your ass hole.” Remembering

how good the ass licking felt, I pulled my legs apart a bit and tried to stick my index finger up my ass,

but it just wouldn’t go in. I told my brother that I didn’t think it will go up my ass, and he said he would

be right back.

He went in the house and came out about a minute later with a bottle of astroglide. I asked him what

it was but he just told me to put some of it on my finger and it will make it easier to put it up my butt.

I did what he said and used the astroglide, and within about 2 minutes my finger was all the way up my

ass. It felt super weird, but good at the same time, unsure of what I was feeling I quickly took my

finger out.

My face was very flushed and I was trembling. I had never been that horny before in my life and didn’t

know what to do with myself.
My brother asked me if fingering my ass felt good at all, and I said, “you were right, that felt super

good.” A few minutes passed and my mind started to clear and started to get uncomfortable about

being naked around my brother so I excused myself to the bathroom and put on some g string

underwear and a large oversized shirt that I would sleep in that night.
