babysitting my sister

dad is gone and mom has to work double shifts so I have to look after my little sister

Dad took off with his gay friend and left us with next to nothing. Mom went back to work at 2 jobs to keep us from living on the streets. I didn’t really mind after all my sister is 10 and starting to get tits and a great ass.
Mom would be at her 1st job at 10 am and be home by 3 pm the go two her second job at 6pm and work until 2 am. plus work all the of the weekend she could get. I’m 15 and not into sports so after school I head for my sister’s school and walk her home. I then make her help me with the house work and starting dinner. Mom gets homes has a nap and beats dinner and is out the door again.
After the dishes are done we do our home work and watch a little TV before it’s her bath time. I started a couple months back going in the washing her back and her golden colored hair. I also did that so when she had her eyes closed so soap wouldn’t get in her eyes I could check out her tiny but growing tits and if enough soap moved from her lap i would see her still bare crack of a pussy.
After her bath she would sit next to me in her nightly which is one of dad’s old t-shirts and a jacket she used as a robe. The jacket was short as is the t-shirt so her pussy is almost showing. It got cool outside so to help keel warm I put my arm around her and pulled her in tight. By doing so her pussy came into view and I started to get a hard on. I didn’t think that she had noticed until she said ” Jeff is your cock getting hard cause my kitty is uncovered?”
I always tell her the truth and told at was because her kitty is showing and also cause she is becoming so sexy. She looked into my eyes and slid my hand up to her tiny tit saying ” Do you like this as well?” I groaned as I felt her nipple go hard under my fingers. By now I was as hard as I could get and my sister put her hand on top of the tent in my sweat pants and asked ” Can I see it? Jeff you can see my kitty so can I see yours, please?” With my other hand I pulled my sweat pants down showing her my 6 inch rock hard cock which she grabbed without asking and almost made me cum right there. She pushed my hand down to her kitty from her tiny hard nipple pushing my fingers against her crack. She was the first pussy I had touched and only the second tit I had touched.
I asked if she wanted to go to my bedroom to be more comfortable? And she nodded her head. Once in my bedroom she grabbed my sweat pants which were already under my cock and pulled them to the floor. I pulled her jacket and t-shirt off looking at her tiny and oh so sexy body for the first time. I then pulled my shirt off as we got on the bed. I bent over and started licking and sucking on her left nipple and she pull her hand behind my head holding me there. I slid my hand down to her next to hairless pussy pushing my finger between her crack and down to her wet hole. after a couple minutes she took ahold of my hand putting my finger on a tiny bump saying ” There, right it really feels good when you rub me there.” As i rubbed her body would give little jerks as she started moaning saying how good it felt.
I wanted to see what I was rubbing so I moved down and got between her wide open legs seeing nothing more then a tiny pink bump and that there was clear stuff coming out of her crack a bit farther down. I had heard of eating pussy so I though I would give it a try. I lowered my head to her pussy and my sister said ” What are you doing?’
I told her to relax as I give her a long lick. I licked and sucked on her hole pushing my tongue inside of her making her squirm as her moaning got louder. When I started licking hard on her tiny bump she went totally nuts for a few seconds then grabbed my hair as her whole body came off the mattress. She went stiff as a broad when started humping my face. A gush on stuff came out of her pussy hitting me on my chin. As she relaxed breathing very hard I licked the stuff coming out of her and found it not that but tasting but also nothing like I had tasted before. Was this female cum, hell I didn’t know but my little sister was purring like a cat would.
She looked down at me and said ” Jeff I love you, I really do you that don’t you?”
I said that I loved her as well as I licked her little bump again but this time she stopped me saying it was get a little bit sore. I moved up beside her and she kissed my lips as she hugged me hard and wrapped her lower thighs around my hard cock. She pulled back saying ” Jeff if I have a hole down there and you have that hard pole should it go in my hole? Should we try and see if it fits?”
I said ” What you’re talking about is called fucking and yes it will fit I think but do you think we should do that for sure? I mean 0nce we do it we can’t undo it and it could cause you to have a baby.”
She only nodded and tried to pull me on top of her. I though, ok I will only push maybe a half inch inside of her and when I felt myself coming I would pull out. I lined up and started to push only the head of my cock inside of her but she wanted it all and dug her finger nails into my hips pulling hard and forcing me to go more then half way in. She let out a scream that it hurt and for me not to move. I tried to pull out but she held my hips moaning for me to stay where I was. After maybe 2 minutes I could see the pain leaving her face and her hands pulling more of me inside of her pussy. Once I was all the way in she said ” OK Jeff but move slow please, it still burns a bit but it getting better.”
I started moving slowly in and out and I could see her face changing from pain to pleasure. She started moving her hips in time with me as she moaned “faster, go faster.”
I could feel I was about to cum and all I could think about was fucking her and coming. Her breathing was getting very hard and deep as was mine and just as I pushed in as deep as I could go I started coming deep inside my sister’s pussy as she came with me.
After I came I rested on top her kissing her forehead as I started moving inside of her again not never really going soft. This time I lasted a lot long and my sexy little sister came 3 times before I came once again deep inside of her.
I looked at the clock and it was after midnight as I said we better get cleaned up before mom comes home. We showered and as I dried her her my cock was at face level so she pulled my cock to her face kissing my cock before pulling my in her mouth blowing on it. I asked if she was trying to give me a blow job? She nodded her head and I said it’s called a blow job but you have to suck and lick not blow on it. She began sucking on me and pumping her hand on me as well. About the time I had her hair dry I felt I was going to cum for the 3rd time that night and told her so. I tried to pull out but she wasn’t having any of it and I came in her mouth. She pulled back after I filled her mouth, looked at me as she swallowed. I said ” Why did you do that sweetheart? You didn’t have too you know.”
She said ” Remember how you made me cum with your mouth, well it was my turn. Your stuff tastes different then mine dose, a little more salty and a bit bitter but not that bad. and besides it was my turn.” She always like to have fair play and I guess she wanted this to be the same way.
That was last Friday night and we didn’t do it again until Monday. Last night we only did the thing with our mouths which my sister is really getting good at and says she wants to learn how to take all of me in her mouth. I love the way she goes insane when I lick and suck on her pussy. I know she’s my sister but I don’t think I will never want anyone else to be my lover. I am worried about getting her pregnant cause she only wants me to cum deep inside of her. I guess I will need to get some condoms cause it won’t be that long before she starts having her periods to what I’ve been reading on the internet.
