Very happily married to my soulmate/lover/best friend, we found each other in a very unique way and knew from the first moment we saw each other that we were destined to be together. She was under the impression from her doctor that she could not have children, so we never used any sort of birth control. She is a petite woman while I am a taller but average sized man, well endowed, her vagina is very wet and tight gripping my cock well, we can both feel when the head of my cock is at her cervix, its extremely pleasurable for her. I also produce a generous amount of precum and added to her juices it really helps for deep penetration, stretching her vagina as I gradually get deeper until I hit the cervix. The first time we made love it was deep penetration flooding her cervix with cum and remaining inside her for a short period of time after orgasm, cuddling and making out. It was a couple years later when she saw a new doctor who examined her and told her there was nothing preventing her from being pregnant. This was after two solid years of very active sex together, continually having unprotected sex, cumming inside her every time. So after her telling me what the doctor said, I thought to myself to test that. So for the next couple months I fucked her very deep hitting the cervix all the time which would make her orgasm too, she loved that feeling and I kept flooding her cervix with cum. I do cum in large amounts, if she gets up out of bed right after sex, she begins to drip with my cum and her juices combined, but during those two months I never pulled out right away. I was making sure her cervix was flooded with cum keeping my cock mounted deep in her until it got softer and slipped out. I was trying to impregnant her and it worked, she became pregnant with our son which was a dream come true for her, she always wanted to give birth to a baby boy and she did nine months later.
Also wanted to add that during those deep penetration sessions we usually started out doggie style or her bent over the dresser (when having sex in the bedroom) and finished off missionary style. We love looking into each other's eyes and making out after we both orgasm.
