Incest Sex Story: Chapter 2: Kristen Gets Horny About Rick - My mom was turning 41. While not nearly as traumatic as her 40th birthday, it's still hard to "age" another year. Leave it to my cousin Rick to make her feel young again.

I was talking about my so -called dilemma with my cousin Kristen one afternoon while over at her house. Her mom, an extremely successful realtor, was out showing a house to a client so we had the place to ourselves.

“Alright ... so what did you get YOUR mom for her last birthday?” I asked, perplexed with everything.

“Well, she doesn’t hit the big 4-0 until next year so we celebrated her ‘first’ 39th birthday.” Kristen replied with a grin.

“OK ... so what DID you do?”

“I set her up with a date,” Kristen answered with a mischievous grin. She managed to say it in such a matter of fact tone I had a hard time reading her. Then she started to grin even more and couldn’t hold back anymore adding, “Of course, he was only seventeen.”

Now why didn’t THAT surprise me? Heck, I should’ve guessed it immediately knowing my cousin - and her sexy mom. Kristen was twenty now, having finished her sophomore year in college, so you would think she’d be losing her interest in the local high school boys. Not Kristen - quite the opposite if anything. I’d lectured her enough in that past about the dangers of screwing around with underage boys but she just brushed it off, claiming nobody ever prosecuted a girl for doing it, just guys. I tried mentioning the news stories about teachers going to jail for having sex with students - eve some 18 or older, but she just dismissed them with a brush of her hand. It didn’t help her mother encouraged her as well. THAT had probably more to do with the fact her mom liked it when she brought her young studs home where the luckyboys learned they were getting a two for one deal, and a mom-daughter one at that. So far as I knew, none of them turned THAT wet dream fantasy down! But this was the first time, at least that I knew of, that my Aunt Linda had DATED one of her boy toys.

“You’re kidding! Who was it?”

“Well, you remember Jonathan, the kid next door to us?”

Well duh, how could I NOT? I remembered him from a few years back when his parents had moved in. From Day One he was a perverted little Peeping Tom, always staring at me when I came and went and lord only knows when else. Of course he’d grown up since then, well obviously so from the way Kristen was describing him.

“God Kelly, I remember the first time I blew him,” Kristen was going on, “Poor kid didn’t know whether to shit or go blind! And then when I told him he could fuck me ... oh my god, I thought he was going to faint.”

“OK, OK, so he was another one of your boy toys, I get the picture,” I interrupted. I’d heard the same story umpteen times before. The names and faces changed but the end result was always the same. “So how did you get him with your mom?” I asked, hoping to fast forward to the real story.

Kristen pouted for a second, evidently peeved I’d stopped her from giving me more details, but she sighed and changed the subject to what interested me saying, “Well, I convinced my mom to take him to the mall and pretend he was her son - you know she’s always wished she had one.”

I couldn’t help but grin at the image forming in my mind. For a woman who had slept in the same bed with her daughter since her divorce almost eighteen years ago, I could only imagine how it would’ve been to add a boy into the mix!

“Of course, it didn’t take anything to get Jonathan to go along with my plans,” she continued with a wink.

“So what happened?” I asked, my voice more on edge as I waited for her to get to the point.

“Basically, you could say she had a chance to relive her teenage years,” Kristen explained. “You know my mom, she’s always up for something new. Once she realized what my ‘present’ was, she took the ball and ran with it.”

“As in?” I asked, trying to direct her.

“Well my slutty cousin, you of anyone should know how it goes - aren’t malls sort of your specialty?” Kristen asked teasingly.

“Well, back in high school maybe,” I mused. Thoughts of teasing clerks, fucking in bathrooms and dressing rooms, and just general flirting quickly came to mind but those days were years ago for me.

“THAT’S the whole point,” Kristen exclaimed, “She got to pretend she was back in high school and just made a fun day of it.”

“She let him fuck her I assume?” I asked, although I was pretty certain what the answer was already.

“Duh, earth to Kelly, what do you think?” Kristen blurted out.

“Well, that’s all well and good but I can’t do that for MY mom’s birthday and you know it,” I griped with a frown. “She would never do anything like that with a neighbor boy. You’ve heard her anti-adultery lectures enough I’m sure!”

Kristen looked at me with an expression of exasperation, as if I was missing something obvious.

“Now what?” I sighed.

“THINK girl, do I have to spell EVERYTHING out for you all the time?” Kristen replied, he tone a bit exasperated now.

Well, I wasn’t as crazy as Kristen, that was for sure, but I wasn’t stupid either - or so I like to think. After all, SHE is the blonde in the family! This time, though, she had me stumped.

“Oh geeze Kelly, I can’t believe you sometimes,” Kristen sighed a little melodramatically, “Do the initials R-I-C-K mean anything?

Well why hadn’t she just come and said it instead of making me feel as stupid as I did now? Of course there was the perfect option - her horny teenage nephew. He was nineteen now so a little older than Kristen preferred, but for my mom he was still a “boy”, albeit a boy with one heck of a cock.

“So what do you think?” she asked with a big grin on her face, obviously quite proud of herself for coming up with the idea. “After all, they ARE sisters.”

There were tons of logistical problems to work out but I had to hand it to her, the concept was perfect. My mom and I sometimes went out and teased the guys in the malls and such but we WERE mother and daughter so there wasn’t any element of fantasy from that perspective. My mom had always said she wished she could have had a son so why not let her have one for a day? Of course, his mother, my Aunt Shari, might have something to say about it if she ever found out but then this was nothing compared to what her husband and son were doing to her youngest daughter behind her back!

I looked over at Kristen and noticed she was playing with herself under the skirt she was wearing. Actually, it would have been surprising NOT to see her as I think sometimes her hand is permanently attached to her crotch but she wasn’t just doing her usual absent-minded fingering, this looked to be more serious.

“Hmmmm, I take it someone’s horny today?” I giggled, pointing at her crotch. “What’s the matter, been longer than 24 hours since you’ve been fucked?”

Although I meant to tease her, the reality was it wasn’t much of a stretch. My was probably the biggest slut to ever fuck her way through our high school and now in college she majored more in prostitution than anything in the school catalog. I knew this summer she was “working” for her mom, helping her to sell real estate, mostly on her back. She’d confided in me she didn’t want to go back to school so who knew what she would be doing in the future but one thing was for sure, it would be something kinky if I knew her. I swear the girl DID get laid every day so the 24 hour joke was more on the mark than you might think!

“I was just imagining Rick and your mom naked together in her bed,” she sighed, pausing her reverie for a moment to converse with me. “You know, she’s never done him with me there. Why do you think that is?”

Well, I knew the reason but it wasn’t something I wanted to tell her. Whenever Kristen got involved in something she tended to hog the spotlight. My mom viewed her times with Rick as HER time to just enjoy herself and be pampered by a horny young guy wanting to do anything to please her. Why would she want Kristen there vying for his attention, not to mention his dick?

“She doesn’t do him all that often, you know, so maybe you just haven’t been there at the right time,” I lied. Normally I never lied to my cousin about anything but there’s a time and place for everything. Kristen pouted but it was more put-on than anything.

“God, can you imagine him doing her in some store?” she asked with a slutty grin. “I’ve never heard of your mom doing anything like that.”

“Well, from what she’s told me, her teen years were a little wild,” I answered adding, “And don’t forget your mom claims she was even worse.

“Yeah but can you imagine your mom doing it NOW? God, she’s so conservative sometimes I wonder know how you ever got fucked by your dad the first time!”

For whatever reason, I hadn’t told her about my mom’s dealings with Rick a little before when her best friend Tammy was visiting after my graduation. There was no particular reason, I guess I just had never got around to it. Well, no time like the present!

“Oh my god, you’re kidding!” Kristen exclaimed as I started telling her about how my mom and I had sucked Rick right in front of her best friend. Well that was nothing compared to her response when it got to where Rick was fucking Tammy and me for her to watch.
