It was about a week before my 40th birthday and my wife Cara, who's only 36, and I were lying next to each other in bed - naked, sweating and breathing hard having just finished an intense lovemaking session.
"Be honest with me, what's your number one sexual fantasy," I asked.
"I really don't know, you satisfy me in every way, every time. What's yours?"
"A threesome, which is every guy's fantasy, and I want your sister Farrah to be the third."
"You just want to fuck her because you think she's sexier than me."
"You've known that's my fantasy," I told her. "Remember last time she visited and you were worried about her walking in on us. I told you she had three choices if that happened: watch, leave or join in. You weren't happy with that response if I recall correctly. But remember, I love you and would never cheat on you.
"So the fantasy is to see what it would be like with two women at once and wanting the third to be someone we know, who I think is sexy, and who we can trust not to say anything to anybody afterwards. Would you rather I have named one of your friends or co-workers instead of your sister to be the third?"
Cara appeared a little stunned and stayed quiet. I knew she wasn't feeling confident in herself having put on a bit of weight in our 10 years of marriage. I love her shoulder-length light brown hair and blue eyes. But at 5-foot-3 she didn't like how the weight gain was showing in her face, waist, hips, ass, and legs. I think that although it shows, she carries the weight well. She was happy (like me) that her 42C breasts still held their form quite nicely. However, she knew that I thought her single, older sister Farrah, who was 38-years-old, 5-foot-4, with blonde hair, blue eyes, thin waist, perfect ass, runner's legs, and 34Cs was hot.
Allow me to describe myself, I'm 5-foot-8, a few extra pounds of fat, short brown hair, brown eyes and glasses.
"It's just a fantasy," I said to break the silence. "It's not like it's actually going to happen."
Cara had kept it a secret from me that the next day Farrah had called saying she'd be travelling to the party alone since her boyfriend had dumped her. She also kept it a secret that Farrah would be staying with us in our guest room instead of at a hotel, like we initially thought.
The Friday night party was a blast and shortly after 1 a.m. everyone had gone home, leaving Cara, Farrah and I alone. I don't hold my alcohol well so I only had one drink at the party, but to my surprise Cara had several more drinks than she usually does. Cara and I were sitting next to each other on a loveseat while Farrah was on a catty-corner sofa wearing a loose fitting top that showed off her cleavage and a miniskirt that showed off plenty of leg. Cara was wearing a skirt and a frilly blouse.
"The party was great," Cara said. "I don't remember the last time we hosted and had that much fun."
"You guys have a lot of fun friends," Farrah said. "I had a really nice time."
"I'd like to thank both of you for a wonderful birthday party," I said. "Do we have any plans for the rest of the weekend that I don't know about?"
"Not really," Cara said. "But I'm sure we can think of something."
She started to slowly rub her breasts against my back while reaching around to rub my crotch
"I know you're checking her out, trying to see what, if anything, she has on under that miniskirt," she whispered in my ear.
Farrah was smiling and said something about making plans, was clearly getting annoyed with her sister's behavior. I don't know if she noticed my eyes checking out her body instead of making eye contact while we talked. Cara continued to press her breasts into me while rubbing my crotch. As a result, she felt my cock stiffening.
"I like the effect my hand and her looks are having on you." Cara whispered to me and licked my ear before she unzipped my fly and took out my cock and started to stroke it.
"I can't believe you. I'm outta here!" Farrah shouted and got up to leave. "So much for some nice family weekend plans."
"Where are you going sis? Don't you want to taste it?" Cara said.
Cara's never behaved this way before, so I had to assume she was drunk or really buzzed. Farrah and I looked at Cara in stunned silence before looking at each other and smiling awkwardly. I never thought Farrah was interested in me in that way and has threatened to cut my cock off if I ever cheated on her sister. I guess the sight of my cock and her sister's invitation had put other thoughts in her mind.
"Hey sis, he's got the hots for you. Don't you want to give him a birthday blowjob to see his cum tastes as good as I've told you it does?" Cara continued with a laugh in teasing her sister.
Farrah took another look at my growing hard-on.
"Hell yeah" she said as she took off her blouse and bra before she got down on her knees in front of me. We eased my pants halfway down my legs so she'd have full access to my cock and balls. She slowly ran her tongue up and down the length of my stiffening cock, taking time to swirl her tongue around the head.
I reached over, undid Cara's bra and tossed it aside, then leaned my head over and started to suck on her tits. At the same time Farrah lowered her mouth down over my raging hard-on as my cock felt as hard as steel. Her lips felt like they formed a vacuum seal around it as I felt the tip hitting the back of her throat. I moved my face from Cara's tits wrapped an arm around her looked into her eyes.
"Thank you," I whispered to my wife before kissing her deeply, sliding my tongue into her mouth.
The kiss was interrupted when I threw my head back and closed my eyes in extreme pleasure.
"Oh yeah," I groaned as Farrah started playing with my balls while she had all of my cok in her mouth.
"Is she that much better than me," Cara said as she grabbed my face and looked into my eyes.
"Yes she is, you could definitely take some lessons from her," I said.
