Kim was breathing hard as her orgasm was building, porn on her laptop, vibrator on her clit. Almost there when her phone rang for the third time in the past two minutes, lit up with the face of her of her sister-in-law. Kim was very close to Samantha. They had become best friends since she married Samantha's brother, Eric.
"Shit Sam. I was just about to cum," she yelled at Samantha answering the call this time after ignoring the first two. "What's so important you have to interrupt my morning pleasure?"
"I need to talk to you," Samantha responded urgently. "It's about Jack," she said referring to her husband.
"Oh my god. Is he alright? Did something happen to him?" Kim asked, worried now that something horrible had happened to Jack.
"No. He's fine. I mean he's fine physically. Nothing happened to him," Samantha replied. "I need to talk to you about something he asked me to do," she said with a worried tone of to her voice. "Can I come over?"
"Sure," Kim responded. "I'll put on another pot of coffee."
"Or maybe break out a bottle of wine," Samantha said urgently.
"At ten in the morning?" Kim responded. "This must be some serious shit," she commented.
"It is," Samantha said.
Ten minutes later Samantha rang Kim's doorbell. Kim let her thirty-five year old sister-in-law in and led her into the kitchen where Kim had opened a bottle of Pinot Grigio and set out two glasses. The two women sat down. Kim poured them each a glass of wine.
"Well? What is it?" Kim inquired.
"You know how Jack and I take turns asking each other what we want to do special for Valentine's Day?" Samantha started out.
"Sure. Eric and I do the same thing," Kim replied.
"This year is Jack's turn," Samantha began to explain. "He wants," she hesitated. "He wants to be a cuckhold," Samantha she said, her voice cracking. "He wants to watch me get fucked by another man."
"Wow," Kim exclaimed. "That's some weird shit."
"He really means it," Samantha sad. "He told me he has had this pent up desire for a long time and finally had the courage to ask."
"I've heard that it's not that uncommon," Kim responded. "But Jack seems so straight-laced."
"We've done some kinky things," Samantha explained. "Jack is very adventurous sexually. One Valentine's Day we went to dinner and he fingered me to an orgasm under the table with strangers all around."
"What about you?" Kim asked. "How do you feel about be fucked by a strange man?"
"I don't want it to be a stranger," she responded bluntly.
"Who do you want it to be?" Kim inquired, her curiosity now peaking.
"Well," Samantha started to say demurely. "When I was in high school I had a crush on my brother Eric," she said looking away from Kim.
"What?" Kim was shocked by this revelation from her sister-in-law about her husband Eric.
"I used to fantasize about him when I masturbated," Samantha added. "It kind of got real for me after I secretly watched him masturbating one night. He didn't close his door all the way so I peeked in."
"It's a good fucking thing I have another bottle of wine," Kim said gulping down her glass, amazed at what she was hearing.
"When he shot his load I crumbled," Samantha confessed.
"Wow. This is a lot to absorb," Kim told Samantha.
"I know it sounds depraved," Samantha continued, "But the only way I am going to make Jack happy would be to do it with Eric."
Kim poured herself a third glass of wine and sat there silently for a few moments pondering the crazy idea of her husband screwing his sister.
"You know I love the both of you," Samantha stated. "I would never want you to feel that I was asking for something that would hurt our relationship," she added.
"Eric would never go for it," Kim stated matter-of-factly.
"That's why I came to you," Samantha said. "You have to help me and get Eric to do it," she pleaded.
"I don't know. I'm not sure about this," Kim responded. "Let me think about it."
"Alright," Samantha said. The two women sat there in silence, wild crazy thoughts going through their heads while they each downed another glass of wine.

"Eric," Kim started to address her husband after dinner. "I think it's my turn to suggest something special for Valentine's Day," she told him.
"Yea. Last year we both had a great time at the strip club. That was my idea," Eric responded.
"I got so wet getting a lap dance from that one girl who kept shoving her nipples in my mouth," Kim remembered.
"So, what are you thinking about for this year?" Eric asked.
"Something along those lines where I could have contact with another woman," Kim replied. "Maybe a threesome with another woman," she threw out there waiting for her husband's reaction.
"That sounds pretty wild," Eric said. "Are you sure about that?"
"It's something I at least want to explore," Kim told him.
"I thought it was very hot watching you with your hands all over that dancer last year while she rubbed her tits on your face," Eric answered. "Watching you with another woman would be great for me."
"Good. So you wouldn't be jealous at all sharing me that way?" Kim asked.
