We Chose to Have My Wife Naturally Inseminated After the birth of our second child, my wife and I agreed that we didn't want anymore. After weighing pros and cons of safe sex versus surgery, I decided to get a vasectomy. At the time it seemed like a great idea, but as several years passed, my wife started yearning for another child. The cost of a vasectomy reversal is astronomical, and not guaranteed, and she was against adoption because she really wanted to have the experience to carrying another child full term again. So with those obstacles facing us, I decided to do a little research. I found a website dedicated to "Natural Insemination." Natural Insemination is basically a man who agrees to have sex with the woman to impregnate her, with the understanding that he will have no obligation to the woman or child afterward. Many people are now starting to practice natural insemination, because it is a natural way of conceiving a child, instead of the cold, emotionless practice or artificial insemination. I soon found an NI donor not far from us. He seemed to be a perfect match, and had a clean history. I presented all of the information to my wife, who at first was very hesitant. She finally realized that this would be the best way, if she actually wanted to carry. Besides, it would have a side benefit... the thrill of her sleeping with another man. That was a thrill we both looked forward to. Her only condition was that she wanted to be blindfolded, so she could not see him... and she wanted me in the room with them. We waited through her cycle until she was ovulating, and had our "donor" meet us that night. He was everything his pictures and profile described... dark hair and eyes (like me), athletic build, and about 5' 9" (not far from my height of 5'7"). I lead him up to our bedroom where my wife was laying naked and blindfolded, facedown on our bed. Our new friend quickly disrobed and shocked me with the size of his dick! He was at least a solid 8.5", and almost as thick as he was long! I suddenly felt my own cock spring to life in anticipation of him sticking this thick monster into my wife. He got behind her, spread her legs a little for easy access, and started rubbing her pussy lips to get them wet before he stuck it in. I could see it was working. She started moaning, and I could see pussy juice glistening off her lips and his fingers. He then climbed on top of her, and whispered in her ear, "I'm getting ready to start. I'll start slow, and just let me know if you need me to go slower." "Mmm, ok," she replied. He positioned himself between her butt cheeks, with his hands on her back, and slowly inched his massive cock inside of her wet hole. I could hear her gasp, and saw her grit her teeth a little, but then she loosened up and started moaning again. He slowly rocked back and forth, plunging deeply inside of her. I crawled to the other side of the bed. I kissed her mouth and rubbed her shoulders as he continued thrusting into her from behind. He then brought his chest down on her back, and reached one hand underneath her to massage the top of her clit, as he continued fucking her. At that point she was panting and moaning loudly in between our mouth kisses as he continued his assault on her pussy, and kissed her back and neck. Suddenly she began shaking furiously, and started screaming, "Oh my God, I'm cumming, I'm cumming!" This must have triggered the same reaction in him. Suddenly he thrust hard and deep in to her, and started grunting, until he wrapped his arms around her sides and slammed himself into her as deep as he could. I knew he was spraying his load inside of her. Seeing the man cum inside my ravaged wife was all I could take. Suddenly I came, without even having to be touched. We all laid there in breathless ecstasy for about 30 seconds, before remembering why we had set that up to begin with. I quickly helped my still blindfolded wife roll over onto her back, and propped her legs up in the air, so his sperm could better flow to its destination. Not only did we share an amazing experience, but it worked... and it was soon confirmed that she was pregnant! Nine and a half months later we welcomed a baby boy in to our family, and we have absolutely no regrets on how his life started.
