I'd been married to my wife, Nicole, for three years when I first questioned her fidelity. We were in our late twenties and had a young daughter. She worked nights as a hospice nurse, on call to travel to peoples homes at all hours. She usually was able to get home after midnight and we'd spend the night cuddling or making love (at least until her pager inevitably interrupted us).
One night we had plans to get a bit dirty, and she was wound up and horny when she got home around one. We started making out and I snuck my hand up her thigh. Suddenly she pushed me away, claiming she wasn't in the mood because of a rough stop at one of her patients homes. I would have accepted her response if moments earlier she hadn't been squeezing my manhood through my jeans, When I began questioning the change in mood, she offered up a blowjob, a true rarity in our bedroom. Of course, even with my suspicions I took her up on it. It was the deepest, most lustful sucking I've ever received. Hot mouth, very wet, tongue snaking down to my taint. But I couldn't shake the feeling that their was a different reason she didn't want my hand near her pussy.
After she fell asleep I slipped down the hall to the spare room where she keeps her clothes to save space. I found her panties from that night. Initially I was calmed by the sight of her typical cotton boy shorts. "Not a thong, so she wasn't trying to be sexy" I thought. But as I turned them over, I could see that the crotch was still a tad damp. I turned them inside out and thought I could make out a thin white film. "Shit!" I thought, "That certainly looks like one thing only." But I had no proof and the evidence in her panties was by no means indefensible. So for the time being I let things slide.
A few months later we went out for her birthday. She asked if an old friend, Johnny, could meet us. I knew they had once dated, but it had been over a period of about two weeks so I wasn't concerned. Besides, I'm 6'3 and despite being heavyset, am pretty strong from a past obsession with weightlifting. She showed me his picture and I saw my polar opposite, 5'6 and scrawny. No problem. So the night is great, lots of people stop out to buy her drinks. But as the night wears on, she spends more an more time at his side. Eventually, while I'm talking to some of her coworkers I lose track of her. After about 40 minutes I decide to look around. No one had seen her, but the last I had heard she was going out to the bar's patio with Johnny.
I made my way out the door, finding a lot of people, but not the two I was looking for. Suddenly a side gate swung open and I spied my wife slipping back in. I waited where I was until she noticed me and made her way over. I tried to act nonchalant as she explained that they had been remembering an old friend who had passed away. I made a comment alluding to why they had to go to the parking lot to talk, and she made some excuse about Johnny wanting to smoke. I looked around at all the people with cigarettes on the patio but before I could point out how obvious the lie was, she shoved her tongue into my mouth. Her lips were soft and here tongue was hot, like she'd been making out with someone. Or doing something else to build friction.
I kept my mouth shut once more, deciding to bide my time until I had something indisputable. Unfortunately the next day I found out I was being downsized. I didn't make enough money for it to threaten us too much, but it was emasculating and depressing nonetheless. That night I called her at work and told her I needed her company and couldn't wait to see her. She was good at talking me through things. She assured me that she was leaving soon as she had no patients that night. About twenty minutes later I got a text telling me she would be another hour or so due to paperwork. "No big deal" I thought and went to lie down. I woke up to the sound of her tiptoeing into our room over three hours later. I pretended to be asleep and made a mental note to find out what was going on.
The next morning I got up early and checked her cellphone. Mostly bullshit, chatting with coworkers and girlfriends. But then there it was. A message to Johnny's roommate 'Have J call me. I need to be with him and I'm done at work early'. I looked at the time it was sent and saw it was between our call and her text that she would be late. I woke her up, asking what time she had come home. "Oh about 90 minutes after we talked." Wrong answer. So I confronted her, and of course she had a dozen excuses for how it looked, and it all came down to me reading too much into it. I didn't see how she could so bluntly lie to me, but I went with it, letting her think the issue was resolved.
Next time she worked I decided to stop by around the time she normally left her office. She walked out with her phone pressed to her ear. I was too far away to hear her voice, but I could see lust on her face. She hung up and got in her car. Suddenly I got a text that she had one more stop to make that night. I watched her pullout of the parking lot, then slowly followed.
Soon she stopped in front of a small ranch home in a crappy neighborhood. She practically ran to the front door, and while I couldn't see his face, I recognized the short frame that opened it. I slipped out of my car and up to the side window. My heart leapt. She was pressed up against the wall, and he was pressed against her. Their tongues were deep in each others mouths, and his hands were firmly squeezing her ample breasts. Nicole had DDD size tits normally, but it was less then a year since our child's birth and they were still swollen up to an F. She always had sensitive nipples, and even through her nurses scrubs I could tell he was pinching them between his fingers.
Suddenly his head jerked back. I thought she had pushed him away, but realized quickly she had grabbed his cock. They turned a bit and I could see her hand down the front of his shorts, massaging what she found there. He stopped her long enough to pull her shirt off, before she dropped to her knees and slid down his pants. His half-hard dick flopped out, much larger than I expected. Not a freakishly huge thing, but surprisingly long and with a nice thickness. With his small stature though it looked mammoth.
My wife gave it a squeeze, and her tongue darted out to lick the tip clean. I couldn't believe it as I saw her lips spread and gently wrap around the head of his cock. I saw her cheeks pull in as she sucked with all her might, pulling him deep into her. Soon he was buried about 7 inches into her throat, with a little left over that she was twisting between her fingers. I could see it take his breath away. The girl has always had great lung strength and she could almost pull the cum out of your dick before you knew what was happening. He tried to pull back, but she kept the suction on and he couldn't hope to escape.
