Rita and I are both 30 and have been married for five years now. I can honestly say that she’s as drop-dead gorgeous as she was when we met and began dating.

Six months ago we had a baby boy. Before getting pregnant, Rita had a 34C-24-34 runner’s body, but after Kerry was born, her breasts became massive 36Ds that made her look top-heavy and even more alluring. She started exercising right after the birth and got her slim body back, but her breasts remained big while she was still nursing.

Lucky for me, Rita has always had a big sex drive and will make love at the drop of a hat — even more than I realized, as I discovered two weeks ago while we were having a small get-together at our house with a couple of neighbors and a few other close friends.

Most of the party was being held in our lower-level rec room. Once, after Rita had gone upstairs to check on the baby, I had to go upstairs a few minutes later to fetch more snacks. In the kitchen I heard Rita’s voice coming over the baby monitor on the counter. She must have been in Kerry’s bedroom with someone and was telling him she wanted him to come over during the week, while I was at work, because she missed having his “thick cock” inside her.

I stood frozen, not believing what I had heard. Then came what sounded like kissing and moans from both of them. A moment later Rita told the guy they’d better return to the party before anyone noticed they were missing. When the guy said he’d be over at one Tuesday afternoon and she should wear her sexy black teddy, I recognized the voice! It was Todd, from two doors away, a tall bodybuilder type who always wears muscle shirts and tight shorts when he’s out in his yard.

Hearing the bedroom door opening, I ducked into the nearby half-bath and waited a couple of minutes before coming out so they wouldn’t suspect I’d heard them. When I rejoined the party they were talking with the rest of the guests as if everything was normal.

My mind was racing at the thought of my wife cheating. But at the same time I was aroused by the thought of her fucking another man. It had been a fantasy of mine for a couple of years, but I had never dared to broach it with Rita for fear she’d be grossed out. It seemed not!

I didn’t confront her that night, and spent the weekend contemplating what to do. I finally decided I wanted to secretly watch them in action before confronting Rita. So Monday the first thing I did when I got to the office was to clear my calendar for Tuesday afternoon.

That morning while Rita was feeding Kerry, I raised the master bedroom shades several inches and cracked the windows open. I figured that since our rear yard is pretty secluded, I could hide there and peek in the windows and see (and hear) any action in the bedroom.

I kissed Rita goodbye and left for work. All morning I had a raging hard-on thinking about seeing my wife fucking another man. I left work at half past 12 and half an hour later parked just down the street from our house. Then I made my way to our rear yard, and outside our bedroom windows I heard my wife moaning!

Peeking in, I saw Rita, with the black lace teddy down at her waist, straddling Todd’s nude body while he sucked away at one of her giant milk-laden breasts. “Oh yeah, stud, suck my tits good,” she gushed. “I just fed Kerry, so all the rest is all yours.” He moaned as he kept on sucking.

I watched my wife grind her pussy against our muscle-bound neighbor’s cock, and got even more turned on. She reached between her legs and pulled her thong to the side, then lifted her little ass while grasping a really big cock. As she brought her pussy lips down to the tip of the cock, she purred, “Shit, I’ve been dreaming of this thing all week. Now I’m fucking going to have it.” As she slid down on it, she let out a long growl.

She started to slide slowly back and forth on the big cock, and he kept sucking her tit. She groaned, “I love how you fill me up, going so deep inside me and stretching my pussy walls. Oh God, I love this cock! You can have my pussy anytime you want.” She pulled her teddy over her head and hurled it aside, then sped up her thrusts on his cock, while he kept on sucking her tit.

For ten minutes I watched Rita ride Todd’s cock like a woman possessed. Eventually, after she had a screaming climax, he told her he was going to come, and she begged him to shoot deep inside her. Seconds later he let out a groan and raised his ass up off the bed as he plunged all the way in her. She gave a loud cry, then collapsed on top of him. For several minutes they held each other and kissed.

Todd rolled Rita onto her side, without interrupting the kissing. She had a hand between their bodies and seemed to be playing with his cock. After a couple of minutes she slowly kissed her way down his chest and grasped his cock. Seeing it now, I was surprised she’d been able to take something that big in her pussy — and done it with ease!

Now she took a few inches in her mouth and sucked it voraciously. In between groans he said what a great cocksucker she was. Her hand went between her legs and she played with herself while sucking him off. She licked the underside of his cock and sucked his hefty balls one at a time — something she’d never done with me. He kept encouraging her to suck them.

Finally Todd warned Rita that he was going to come, and she started rapidly fisting the part of his shaft she couldn’t take in her mouth. Shortly after that, as he let out a groan, she aimed his cock at her face and he shot ropes of come that landed all over her face. As the jets of come coated her hair and face, she moaned like crazy and gasped, “I love you squirting on me.” She buried her face in his groin and wailed.

When she finally calmed down, he smiled while she used her fingers to gather up as much of his come as possible and put it in her mouth. Then she licked and sucked his abdomen like a vacuum cleaner to gather any remnants of his semen. Once she was done doing that, she moved up toward his face and panted, “Now for your special treat, stud.” She took her left tit in her hand and gave it a good squeeze, and some milk squirted on his face. When he pulled the tit to his mouth and sucked on it, she intoned, “Yeah, suck my tits!”

After about ten minutes Todd told Rita he wanted to fuck her ass. She’d never let me fuck her ass, always saying she was afraid it would hurt her, so I was shocked when she scampered to her knees and said excitedly, “God, I was hoping you’d do my ass again!” She was eagerly offering her ass up to a guy who was seriously thicker than me!

Rita moved to the center of the bed and peeled off her thong, then got on her back and raised her legs to her neck, holding them there with her arms while Todd got in position. He grasped her ankles and held them with one hand while she pulled her ass cheeks apart. He buried his cock in her pussy and gave several vigorous pumps, then withdrew it. Then he aimed it at her rectum and gave a slow, steady push. As he did, she gave a long moan of “Oh God, I fucking lo-ove this! Fuck my ass, baby!”

Todd continued pushing into Rita’s ass until he was all the way in, and I stood there stunned, not believing my five-foot-four wife was taking a cock noticeably much thicker than mine up her ass with no problem! Once Todd was all the way in her, he held still until she begged him to fuck her. Still holding her ankles in one hand, he said she’d have to really beg if she wanted him to fuck her ass. Without hesitation she promised him her pussy every day as long as he did her ass too.

Apparently satisfied, Todd started thrusting vigorously in and out of Rita’s ass, and she went ballistic, screaming and moaning the whole time and begging him to fill her ass with his come. She was rubbing her pussy like a woman possessed, and after a good 15 minutes of power ass-fucking she exploded like a rocket. When he finally emptied his load in her, they were both covered in perspiration. He released her ankles, and she used her bent legs to raise her ass off the mattress until his cock slid out of her.

That was all I could take! I’d been watching for an hour and a half, and my cock was as hard as an iron bar and throbbing like hell. I snuck back to my car and drove to a nearby commuter parking lot, where I frantically beat off twice, leaving my hand and groin a wet, sticky mess.

I cleaned up as well as I could, then drove around for a couple of hours thinking about what I had seen. Eventually I drove home, arriving at what would have been my regular time. Rita met me at the door and gave me a great kiss. She asked how my day had gone. I said it had been a usual workday.

Casually, I went in the bedroom to change, and saw that there were fresh sheets on the bed. Hearing the drier going, I assumed my wife had washed away that evidence of her infidelity! When I asked her how her day had gone, she said she’d just done some cleaning while caring for Kerry.

After dinner we put Kerry to bed, then cuddled on the couch. When we started kissing, Rita took note of my arousal and cooed, “Oh, I know what you want. Let’s go in the bedroom and make love.”

We had a marvelous time; Rita was unbelievably passionate. I didn’t mind that her pussy wasn’t as snug as usual, because I’d had the opportunity to see her with another man. As passionate as she was, in the back of my mind I kept wondering if she was enjoying what I was doing or was fantasizing about what Todd had done to her.

I haven’t confronted Rita yet, but I know she’s still seeing Todd, because she’s changed the sheets three times in the last ten days.

I’ve come to the decision that since she loves having me fuck her doggie-style, one of these nights when we’re doing it I’ll pull out of her pussy and start pushing my lubricated cock up her ass. If she starts to complain, I’ll tell her casually that my cock should be much easier to take there than Todd’s, and we’ll see where things go from there.

I’ve resigned myself to sharing my wife, but I don’t want her doing it behind my back. I’d like to be able to watch her without sneaking around behind her back.
