Ch. 01: First Times
Warning: This story contains themes of cuckoldry. Specifically: our protagonist's wife submits to a woman with a penis (in universe she's fully female, but technology allowed her to get a penis body-mod). So basically, our protagonist is cucked by a woman, if that changes how you feel about this story. At no point will another man be involved in the relationship. Reader discretion is advised.
Tonight was game night for John. He was supposed to be playing video games online upstairs in his office with a bunch of old college friends until late into the evening. Since he was preoccupied, his wife, Zoey - a long black-haired bombshell of a woman with a flat stomach, small yet pert tits, and a tight, round ass - had invited over her best friend from work, Victoria. Victoria was a fit blond woman who clearly spent a lot of time at the gym as evidenced by the muscles showing slightly against her stomach (which John had seen on more than one occasion when she wore a short-cropped shirt). Victoria was a bubbly woman who was more than a little flirtatious, but her most unusual feature was really that she had a penis. It was nearly impossible to hide, given its size, so Victoria didn't really try to hide it. It was a body mod that she had gotten installed during college, and she was damned proud of it. To be totally honest, John was even envious of it himself. He had a secret crush on his wife's friend, and the amount of dickgirl porn he consumed in private shot up significantly ever since she started hanging out with the couple. John didn't mind his wife hanging out with such a flirtatious, big-dicked woman though; Zoey was interested in a threesome with a woman to learn what it was like, but she was more straight than bi. Besides, John just didn't feel jealous of another woman, dick size aside.
John's friends had to hop off of their game much earlier than usual, something about being tired from a long week at work, so he decided he'd head down and hang out with the girls for the rest of the night. He slowly descended the stairs to the living room, distracted by sending memes to his friends on his phone as they all slowly dispersed. As he was about to round the bend and enter the living room, he heard Zoey and Victoria talking, and he stopped in his tracks. They must not have heard him coming down the stairs since he was going so slowly.
"God, Zoey, your tits are so amazing," Victoria said, almost seeming to moan. John slowly peaked his head around the corner and saw Victoria's hand under his wife's shirt. The movie they had been watching was still playing in the background, but the sound was turned way down. On the table were their two wine glasses and three empty wine bottles.
"Unh, no, my tits are too small," Zoey moaned as Victoria's fingers moved mysteriously under the fabric against her breasts. "Your tits are perfect. They're so big, even though you're so thin and fit."
"Shut up, your tits are perfect just the way they are. They're so soft and they fit perfectly in my hand. I can't get enough of them."
John was rooted in place as he watched Victoria press herself against his wife, hands under her shirt, and press her lips to Zoey's in a passionate kiss. It wasn't just a peck, either. Victoria began making out with John's wife right there on the couch, their bodies rubbing together as Victoria's free hand slipped passed the waistband of Zoey's yoga pants.
Recently John and Zoey had been experimenting with edging in their sex life. Nearly every night they'd get freaky with each other - fingering, hand jobs, oral, even brief spurts of penetrative sex, you name it - but they would stop just before they orgasmed. They hadn't been doing it for long, but when they did finally go all the way, the orgasm was explosive. It had been well over a week since John had cum, and he blamed the long stint of teasing and denial on his now painfully erect cock tenting his sweatpants at the sight of another woman shoving her tongue down his wife's throat and her hand down his wife's pants.
At this point John had two options: either sit there and watch, or interrupt whatever was happening between his wife and her female friend. John's hand slowly crept into his pants as he made his decision.
"Wait," Zoey gasped between moans as Victoria finger blasted her pussy. "What about John?"
"He's still upstairs playing his games; you can hear him. Besides, it's not like I'm another man come to steal you away from him. We're just two girls having some fun." Victoria whispered into Zoey's ear, darting her tongue out to tease the black-haired woman's earlobe and send a shiver down her spine.
Still hear him playing upstairs? John wondered to himself. He was so wrapped up in the moment that he had entirely forgotten that he had put on a gameplay stream on his computer upstairs after his friends left, and he never turned it off. They both thought he was still upstairs playing!
"Oh, fuck!" Zoey gasped, as Victoria redoubled her efforts on the married woman's pussy.
