I have been happily married for the past 3 years and hope for many more, i have a great husband and a gorgeous daughter which will be 4 next month. She is beautiful so much so that ad agencies have asked me if they could put her on some adverts for toddler products.

I met my husband about 5 years ago and while we were dating i got pregnant. Now this is where it gets complicated as you will read in the following lines. While we were dating we never used protection and i never got pregnant so i assumed we were lucky and to be honest a relief.

We were the typical couple that had sex everywhere and anywhere, if we had the chance we did it. In that car, in friends houses, in the cinema, at the beach, in the park, basically any place. And like i said before we never ever used protection.

(the next couple of paragraphs i will be quite vague with people and places)
During a particular situation on a trip with the family I went on a long walk with a cousin who is absolutely stunning. All of the females in my family said that if he wasn't our cousin they would date him. Anyway back to the walk. we walked for a couple of miles and reached a point where there was not a soul in sight the beach was beautiful and the see was as peaceful as it could ever be. My cousin took of his shirt and shorts and ran to the ocean completely naked, once in there he screamed come on!!. I was hesitant at first, but then i said what the hell so i took off my shorts, panties and my t-shirt and trying to cover my self ran into the water. The water was so nice and warm it felt really relaxing. Then my cousin comes from no where picks me up and throws me in the air and i splash back into the water. We remembered when our moms uses to put us in the bath together and when we used to swim also naked when we were kids well all of us.

When we were getting out of the water i noticed that his dick was hard, i tried to shy away but he had a really nice dick. I asked him why was he hard and he just said that my body got him hard.

I said really?
Yea, you have a nice body.
really?
My breast are to small (I have a 32 b cup)
No, they look great for you. I prefer smaller breasts as they fit nicely in my hands.

He got his hands up and cupped my breasts, and said see perfect. Feeling his hand on by breasts felt good but what got me turned on in this awkward situation was his dick touching my pelvic area were my pubes are and for some who know why I reached down grabbed his dick and put it between my legs and tried to shove it in my pussy. As it was an really hard position I Grabbed him by the neck and pulled him down on the sand. I had him between my legs and so this time I raised my pelvis to get his dick head in my pussy. He followed my movements and shoved his dick deep inside my pussy. He fucked me for about two minutes when we were both cumming hard. He laid on top of me for a while and then i said we better take all this sand off. We went back into the ocean and I straddled him so that he could fuck me again. We both came again and then washed off.

We got back to the house after a long silent walk. We never spoke of what had happened.

I got back to my boyfriend and after a couple of months I realised that i was pregnant. At first we were worried about what to do, but being the good man he is, he asked me to marry him.

Now we have been trying to have another baby but it has been with no success. And that is when I realised that my baby girl is not his it's my cousins

I can not tell him, as he will be devastated. so I'm in a confusing state. He really now wants another baby, but i know that i am not the problem and he might not be able to have kids.

I have even thought of asking or tricking my cousin into get me pregnant so that no suspicion arrises.

Any suggestions?
