caught my sister

like the title i caught my fifteen year old sister dry humping her boy friend one day he freaked out and took off she was in her panties and bra. she says first off don't tell mom what you saw please. i said ok i wont but it feels better if you are skin to skin doing that. she said really we only have done this one other time.

i said let me show you how it feels skin to skin you will like it better that way she says will i get to come that way i said if its done right you will. she says the only way she can get off is if she rubs herself. i told her i can get you off if you will let me show you. she ok i pulled her panties off and i got on top of her with my hard cock and was humping her she was a little wet already and i was between her outer lips pushing on her clit and she was getting into it. i asked her to pull her bra up and i wanted to feel her tits and suck on them.

which she did i had her nipples hard and stiff in no time i was pushing hard on her clit and soon she was coming hard as i sucked her nipples and felt them. she says that was to best she ever felt and we relaxed for a while then she asked me to do it again, since i had not come yet i did her again and she was so excited she came harder this time. i came a load on her belly. we cleaned up and she says can we do this some more i told her sure thing i liked it too.

well it just sis and i and mom at home now mom went to work and its summer time no school sis asked me if mom left i said yes a while ago why, she says i want to have you rub on me again. ok lets go to your room she took off her pjs and says do like you did before. i was hard in a flash and was pushing on her upper slit and soon i had her going sucked big hickeys on both her tits which are not very big then i sucked her nipples till they were stiff. she was almost to orgasm and i was coming already.

i clean her off and told her i was to quick this time so i will lick your pussy and get you off i was tongue fucking her up to her clit which was all puffy now then she came hard again and was so wet leaking pussy juice. i was ready to hump her some more when she said stop mom at the door watching us, i looked back and mom was there with a funny look on her face.

mom asked very calmly are you fucking your sister i said no we just get each other off and i dry hump her or eat her pussy. then she says what are those marks on her boobs i said i sucked them to hard the other day.
next mom says how long have you two been playing sex games together we told her about two weeks or so. next mom says we need to have a talk tonight when i get back. the only reason i came back this morning is i forgot my i pad for work.

that night after dinner mom had us sit and she starts talking about sex and what can happen and how and all next she says i did enjoy watching you two this morning it got me to thinking about sex again.
then sis says do you want Tim to lick you like he does me or dry hump you and suck your nipples it feels so good. mom turned bright red and says i don't want to talk about it thank you.

next morning its Saturday mom was us both at the table and says if you two go any farther with this sex stuff you might have a problem like getting pregnant. sis says real quick he doesn't put it in me or any thing like that. mom said then it just a matter of time i will assure you that you and he will want more than dry humping and licking pussy.

mom says i want to watch you do your sister just like you did before and not worry about me watching you two sis says that's kind of weird isn't it mom says i excited me before when i saw you two going at it.
mom says go ahead and lick her or dry hump which ever you want. i said we can do this i guess. sis took off her shorts and spread her legs and i went down on her and was tonguing her deep as i could and hitting her clit a few times. sis says dry hump me now as i moved up she whispered to me mom is rubbing her pussy inside her pants.

i looked back and said mom come get on the bed and let me do that for you i will be glad to rub your pussy
she looked at us and says i am so horny watching you two. she got on the bed took off her pants and panties and i went to fingering her pussy and clit then i went down on her and sucked her clit till she was coming in no time. i laid on top of her and pushed her top up and off her boobs and said you have big nipples mom she says that's from nursing you both when you were babies. i sucked her nipples and squeezed her big tits. i then started to hump her like i do sis and mom was humping back and saying that feels so good she was getting wet now. then she had a orgasm and says we better stop be before i get to excited.

this started a three way in a way mom liked to have me eat her pussy and then hump her till she came.
this went on for a while and i was sucking my sister nipples one morning and mom says i am next and you can suck my nipples for me. when i finished with sis mom says suck my nipples hard and squeeze my tits
as i was doing that mom was humping against me and says push harder on me to get me going i did that and mom reach between us and held my cock and moved it down and says push now i di and i went right in her pussy and she then says fuck me hard and don't stop till i come.

sis saw this and says mom he could get you pregnant if you do that moms says i will be fine i know my cycle i am safe for now. well i fucked her to orgasm for both of us. she said can he do me that way too
mom says we need to figure your cycle and then we will know its called the safe cycle pattern.
mom and sis got their cycles set up and tells us which days we can bare back when we cant.
i had never fucked my sister yet and mom says today you can fuck her if you two want to try real sex
sis says i want to try it so we did mom helped and we used some KY and i pushed in her and no hymen
she was tight i came to fast that first time. well then next month sis missed her period and she told mom
and they took a test sis was knocked up and mom says she must have figured it wrong then a month later
maybe two mom says well now i am pregnant too i guess the cycle figuring was wrong for me to.

so we are expecting two babies about two months apart and now we are getting things ready mom says all will be fine she has every thing worked out. she came work from home and we can finish school sis will be home schooled so no question then.

forward seven and nine months now sis had a girl and the two months after mom had a girl also. both moms are nursing our babies and i help them both and i get to suck some breast milk if they need to be relieved of to much milk. one morning i was in bed with mom and she had fed the baby and aske me to help relieve some pressure and i was doing fine till i moved and i was on top of mom some and she spread her legs to get comfortable then i was hard touching her pussy that way net i started to hump against her
and she says just fuck me i want it so i came in her again that day twice and guess what she is pregnant again.
