We live in a residential neighborhood, but several apartment buildings back up to our property in back. The closest apartment has a clear view of the back of our house and our patio. Over the years we've learned to close our drapes and blinds to deny the curious...or so I thought. My wife gave birth to our son 3 months ago, and was home for 6 weeks on maternity leave. She had decided to breast feed him, and I have to confess to some jealousy as I watched the little guy sucking mom's big milkers. Seems I was not the only one enjoying watching her milk tho. I happened to glance out our bedroom window toward the apartments one weekend afternoon...and noticed someone peeking toward our house...with binoculars. I took a peek in the living room and found my wife breastfeeding completely topless..and WITH the drapes wide open. I should have told her right away, but to be honest the idea that she was being watched and probably jerked off to made me horny...so I kept quiet. Sneaking back into the bedroom I pulled out a telescopic rifle scope I keep in the closet, and checked out our voyeur. It was two black teen boys! That really gave me a jolt in the shorts. And it didn't take me long to realize that my sweet wife KNEW she was putting on a show. she didn't usually take off her top completely to nurse...and I'd certainly never seen her sit in the rocker in only her nursing bra and panties! And she was getting bolder also...sometimes sitting out on the patio in a chaise lounge to nurse in her robe or just panties. I wondered how much more daring she might get...as i was was jerking off. No sex yet, as she had only given birth a few weeks earlier. As I got home from work one late afternoon my wife was not in the house. I spotted her out on the patio, napping...in only a pair of panties! Instant boner...and I snuck to our bedroom to peek. There they were in their window, enjoying the show too. Thats when i realized my wife was not asleep...she was staring back at those teens....with her legs spread. I started jerking off as I watched her slowly rubbing her pantied crotch until she orgasmed. I barely made it into our bathroom before I shot my load. Obviously my wife was feeling horny from now sex also, and this was her way of satisfying herself...at least thats how i rationalized it. Five weeks after the birth, I stopped by the house on my way back to work from a meeting. I knew as soon as I walked in the house something was going on. I could hear voices from the patio. On a hunch I peeked from the bedroom. There she was naked, on here hands and knees with both of the black teen voyeurs. One had his lips suckling her milkers while the second was thrusting in and out of her squishing pussy. She obviously couldn't wait until after her 6 week checkup for sex, and these boys were giving her what she needed. I had my own cock out, stroking, ready to shoot off already. Thats when I became aware that the boy in her pussy was barebacking...NO CONDOM! I knew I should stop him, but what could I say? I figured she'd ask him to pull out at least, but as his excitement mounted hers did too and they both lost control and forgot all about birth control. Most hubby's recognize that sound their wives make when they're cumming hard, and I knew Jennifer was having a strong climax. Even IF he had thought to pull out in time, she backed her ass up to him so hard and fast it was all over. He grunted hard and thrust into her deep, then held himself in her as his balls pumped out their load. My own load splattered the kleenex in my hand as this black boy seeded my wife's pussy. After a moment to allow the last of his sperm to drain, he pulled out and they switched places. The younger brother was too excited, barely lasting 5 minutes before adding another load up her messy twat. But he stayed in her, waiting a minute, then thrusting again, still hard!! He was able to last much longer the second time, filling her again after making her cum hard. I snuck back out of the house without revealing myself...and by the time i got back to work I had to jerk off in the mens room. She had her 6 week checkup the following week. I'm pretty sure she had sex with those boys at least once a day during that entire week. I wasn't sure if I should let her know that i knew...or play along and enjoy the secret. Obviously she was already having sex, but since I wasn't supposed to know, I had to wait until the Dr cleared her for sex after her checkup. I was eager to get "back in the saddle" that nite, but instead our lives took a different turn. My wife told me that the Dr had determined in a routine screening that she was...pregnant again! All cards on the table...I told her I knew about her having sex with the neighbor boys, and that one of them was obviously the daddy. She shocked me by saying she KNEW I had seen them, and obviously I had no problem with her having sex with the boys in our house. That being the case, we would continue the arrangement as it was now...she having sex with the black boys and me peeping. She planned on having their baby also, and I would raise it. Then she smiled and said " I see by the little boner in your pants that you're fine with this. Good boy! Now put these on, the neighbors are coming over to hear the big news...." and she handed me a pair of her panties.
