my sister in law came to visit and show us her new baby boy she just was at her younger sisters for a couple of weeks. she and my wife were talking about this and that and i over heard her tell my wife that while at her sisters place she had sex with my brother in law twice while she was nursing the baby. now she thinks she is pregnant. well sure enough she is knocked up took a test and she is pregnant.

i asked her on the qt how is she going to sell this to her husband she says simple when i get home i will snip his condom and he will think he did it and no one will know the different if i keep my mouth shut.
i said well there is a price for my silence, she says i know you want to fuck me so why not i can not get anymore more pregnant.

true to her word she and i had sex every chance we had she even let me butt fuck her and i got to drink her breast milk some. she went home in a couple of weeks and all was well did not hear from her if things went bad. months down the road she had a girl and was so thrilled about it. three months later she came to see us and show off her little one. she was nursing the baby and i asked her is there some for me too. she says you like milking my breast don't you i tell her yes it is a big turn on for me.

she says when that happens it makes me want to fuck that's how she got here. i said well i want to suck you dry today since we are alone for a few hours. after she nursed the baby and put her down for a nap she says i am still full if you want to drain my breasts. i was ready asked her to come to her room and get naked
she says if i get naked you will try to fuck me for sure. i told her yes but i will use a condom to be safe.

she then asked me to use a condom and you can have me today as i am horny with all this talk sex and you want to suck my tits. i drained her one breast and started on the other one and she wants to fuck now
so i got a condom out and she rolled it on and says lick my pussy first its been a long time since you did that to me. i ate her to orgasm and then was so ready for her pussy. she was telling me to fuck her hard and long so i slipped the condom off and fucked her to two orgasms and then we were relaxing and i was still in her and going soft she got up and went to the bathroom and she came out and did not say a word to me about anything. i thought she would notice some come but she didn't

next day she says we are going to be alone again sis is going to the mall and told her i was not up to it and i want you to lick me to orgasm again. i ate her pussy and she rolled a condom on me and she said fuck me good like you did yesterday i did just that with the condom on this time. after she pulled the condom off me and says that was a big load of come this morning glad it was caught or i would be pregnant for sure.

we had sex once more before she went back home a few weeks later she called and asked me if any of the condoms broke when we were fucking i said no they all were good why do you ask she says i am pregnant again and was thinking you might have got me knocked up. told her that no broken condoms with us she then says her husband could have had one happen but never said a word about it and i don't want to ask him about it might cause a problem.

she had another baby girl and called us to tell us the news and says she will bring her to see us soon as she can. sister in law called again a week later and says i will be there tomorrow and tells me she wants her pussy licked more this time and i can nurse her tits if i still liked doing that. she got here and first thing she says is can we have a fuck session before sis gets home from work. yes was all i said and she tells me nurse me to and fuck me bareback. bareback is dangerous with us she its ok i had my tubes tied when i was in the hospital so we are safe from now on.

to this day she never had a clue i bred her with her third baby she got pregnant from two of her brother in laws and her husband thinks all three are his. she has sex with me every time she comes for a visit i don't know if she still is fucking my other brother in law.
