As time past me and my brother really got to  getting things heated up `I was now getting a good climax and so was he and like me he could not get enoughwe were doing it some times 4 or 5 times a night when we could sneak into each others room.We would listen to mom moaning as she masturbated we would giggle and talk about how she needed a good fuck.and at times she would date a guy and on these nights me and brother would be by our selves and could really get it on.Then mom got serious about a guy  he was several years younger than her and he got to staying around alot and would spend nights with mom god it was so wild hearing them,he really made mom scream.Then mom and him got married and things went pretty smooth it just made it hard for me and my brother to get it on we almost got caught several times.I thought he was a xexy looking guy and wondered how good he would do it I liked getting fucked by my brother he could give me a good climax but I got to wanting more.And I would sat in jim,s (step dad)lap alot.And most of the times it would be before going to bed and I would be just in my panties and a t-shirt which barely covered my ass.and now i was starting to grow some tits.and we would chat about diferent things and I started teasing him about making mom moan so loud,and I could feel him get hard as I sat in his lapand as time past i would sort of squirm around in his lap and one night mom was taking a bath and i was in his lap and i was teasing him about mom from the night before,he said bet you would like it too.I said I bet I would,And I added that I bet I could handle it too.I could feel he was getting on a good hard and his hand was on my leg right below my panties and i for some reason got brave enough to tell him he could touch me if he wanted and his hand slid up to my panties and he started rubbing me through my panties that was getting wet and then he slipped his fingers beneath my panty leg and let his finger slid up and down my aching wet slit i told him that it felt good,then i whispered i want you you to fuck me.He sort of groaned and said you sure??I could see the passion in his eyes.I said I need it,Mom was still in the bath and brother was at a friends for the night.He got up and taking my hand led me out to the garage  and sat me up on a table and peeled down my panties,his eyes fixed on my cunt with its thin pubic hair that was stating to grow,I spread my legs as he dropped his pants and shorts down to his ankles and his cock looked enormous jumping up and down and so swollen so hard.He pulled me to the edge of the table and i watched as he guided his huge cock to my pussy lips and slowly my pussy lipps parted tight around his head and he kept pushing as his cock slowly went deeper and deeper and he said oh god you are so hot and tight as he started working it in and out all the way up to his balls and i could feel him jumping with excitment  as he hunched and i was fixing to climax and he had only been in a minute and i felt his cock getting real hard and knew he was fixing to cum and i heard a gurgle deep in his throat as he made a hard hunch and i felt his cock jerk and hot cum shot deep in me,at that moment the best climax i had ever had swept through me and my pussy was pulsating tight around his cock.Oh god he moaned you was so hot and tight it was so good,but i should have pulled out but i just couldn,t ohh I,m glad you left it in it felt good cummming in me.we quickly got back our clothes on and i went in first and mom was just coming out of the bath Where is Jim she asked oh he went to the garage to check something as he came in he sort of gave me a grin.I could see his face was a little flushed from our hot fuck.him and mom went on to the bed room and i went to my room and could feel his cum ozzing out of my pussy getting my panties wet and sticky about 30 minutes past i heard the head board of moms bed banging against the wall and mom started moaning and screaming in pleasure,I sort giggled to my self as I thought of us in the garage fucking,now he was taking care of mom.Wonder if my pussy juice was still on his cock,as things finally quieted down i drifted off to sleep .
