Knowing Who I Am

I have to start when I was 15 we were poor mam dad me and my brother one year younger lived in a one bed apartment sleeping on a mattress with a curtain across from our parents bed I used to listen to them having sex and watched sometimes once seeing mom suck dad's cock and him fucking my mom
I watched and rubbed my pussy trying to keep quiet my brother woke and wanted to watch I was scared he would make a noise so I kissed him put my hand on his cock and told him to feel my pussy
In the morning I explained everything to him after mom and dad had gone to work
He wanted to feel me all over and see me naked I let him seeing his hard cock which was about 5 inches long I made him lick me like dad did to mom promising to suck his cock
We spent the next few years accationaly touching each other and making each other cum
He sign up at 18 for the army and before he left I put a condom on him and told him to fuck me really hard not long after my mom got very sick and passed away and dad was a wreck I still lived with him and cooked and cleaned
18 months passed dad was out and I was collecting laundry I went to take off his pillowcase to wash when inside was a pair of my panties the crotch was all wet and sticky from his cum I don't know why but I felt horny knowing daddy was wanking in my panties they were dirty ones I had put in to wash
I wanted him to know I knew so I used my vibrator to cum all over my panties I was wearing even spurted a little pee in the crotch and put them back in the pillowcase
A few days later dad twisted his ankle and had to have a cast my brother came to visit for 2 days and we fucked plenty but safely
I told Dad he could not shower with the cast on how I would give him a sponge bath I told him to strip and put a towel over his groin I was feeling not only horny but cheeky too I washed the usual places on him then slipped my hand under the towel and began to wash his balls and cock I asked him if he enjoyed the present I left for him he was trying to talk when I took of the towel stroked his cock which is 7inches and quite thick and told him how I watch him slide it up mom's pussy after licked her how I would love to feel this same cock slide inside me
While he was telling me this was not right I took off my skirt no panties crouched over his cock and slid down until I was balls deep and told him to fuck me
We fucked realising I had no condom on him I slid off him went 69 and sucked his cock until he exploded in my mouth it dribbled out there was too much dad was licking my pussy and refused to let go until I came I needed to pee bad and he continued licking each time he touched my clit it spurted tiny stream of pee into his mouth
I had to fight him off before I flooded his mouth and face and rushing to the bathroom spurting pee on the way
I got lots of condoms and we fuck at least once a week sometimes two also I fuck my brother when he comes home I go out with boys let them kiss me feel my tits but no fucking
Go forward a few years I still live at home still fuck him my brother completed his service he is married to a nice girl Mary we are similar build and height but her tits are bigger she wears a bra I don't my brother had said to me how Mary really likes me she loves to hug me and kiss when we meet
One month ago my dad and brother went away for the weekend fishing we went shopping we came back to Mary's in her bedroom trying on tops Mary took off her bra it was the first time I saw her bare tits she said a top was too tight maybe it would look nice on me I took off my top and tried it it was too tight even squashed my tits the neck was turtle and hard to take off Mary came to help lifting one side her hand slid over my right breast she did not move it her thumb flipped over my nipple and went instantly hard she was very close I had froze she looked into my eyes and licked her lips I knew what was going to happen but was unable to stop it her lips came down on mine her mouth opened her tongue slipped out and I opened mine wanting to feel her explore my mouth
Within minutes we were making out touching each other I was so wanting her I don't know why she stripped me in a flash looked at my pussy and said I want to taste your cum then buried her mouth onto into and everywhere over my body
We made out all evening Mary said how my brother knows she is bisexual and that Mary wants to fuck me she said he arranged it all I said what if I said no Mary said she would still love me
Mary wants to know if I would like a threesome with her and my brother how he had told her he has seen me naked and how we messed with each other as teens this surprised me Mary said don't worry it's all good how she used to fuck her older brother until he married and moved away
Mary wanted it for my brother how he gets really hard and horny thinking about watching his two favourite women making out when she talks about it she wants to see him go inside me while she kisses me
The next morning we were still in bed when my brother came in told me dad was back home he went for a shower Mary started talking then telling me how sexy I smelt she then started to kiss me stroking my nipples and fingering my already wet pussy she slid down my body opened my legs wide and dived onto my pussy her tongue deep in me licking slurping my eyes were closed in extract and as I came my eyes opened seeing my brother cock in hand put the tip into my mouth I licked and sucked it Mary watching Mary then watched as my brother slipped his hard cock slowly into my pussy Mary kissing me as he did it we each licked sucked and fucked until we were done Mary tells me she is in love with me I never thought I was bisexual until Mary touched me beautiful
