My wife and sister-in-law want me to baby sit my 10- year old twin nieces for the weekend.
My wife Sharon and I have a very open marriage. She likes going to country music clubs and picking up horny cowboys. She is 30, has a very sexy body and loves wearing her cowgirl boots and hat with super short mini skirts and low cut tops showing lots of cleavage of her 38 DD titties. She’s well known at the clubs as a slut who will fuck you if you are a well-built young guy with a big thick cock and you’ll buy her enough tequila to get her drunk enough to fuck. Why do I stand for this? Well first of all I’m not jealous of big cocks. My 11- inch long 8-inch circumference cock is still her favorite to fuck and she allows me to indulge my sexual fetish of CFNM that I’ve been into since I was 15. I’m 35 and in great shape. So I get to show off my cock to any of her girlfriends or neighborhood moms that make me horny. She loves watching their reactions to my donkey dick when we arrange situations where I can reveal my throbbing veiny fuck pole to them. My wife’s sister, Beverly, is one of those ladies who enjoys seeing my hard cock as well. So when my wife told me she and her sister were going to be going out of town for the weekend to visit some friends and I was asked to “babysit” her 10-year old identical twin daughters, I wanted to make sure I heard right. These girls are cute little blue-eyed, blonde-haired beauties. They love hanging out with Aunt Sharon and Uncle Tim. They are in the early stages of puberty with perky little titty bulges, long shapely legs and full round asses already. They are also boy crazy and my sister-in-law tells how she’s always chasing boys off who try sneaking into their bedrooms at night. They have already perfected the art of sexy, seductive wiles and they flirt with me mercilessly . I’ve had conversations with my wife while I’m fucking her about how “the twins” Christie and Christina make my cock hard. I’m sure my sister-in-law gets a full blow-by-blow description of how I fuck her sister and what I’ve said about her girls. So when Sharon and Beverly informed me about the trip, I told them right up front, “I don’t think I can spend an entire weekend with those two without showing my cock. A lot!” Sharon and Beverly giggled and Beverly said, “ Oh I have no doubt you’ll be jacking off that monster in front of them all weekend! But they are already boy crazy and they have seen plenty of little boy dicks.” Sharon chimed in, “you know Baby, it’s just a matter of time before they find out Uncle Tim has a giant cock so this is as good a time as any to show it off to them. Let them have plenty of time to look at it, play with it, see it cum. They are very mature for their age.” “And horny!”, added Beverly. “ I’m sure they will enjoy it as much as I have!” Sharon nodded in agreement. So that’s how I ended up stand in the driveway with these two nymphettes waving good bye to their mom and my wife. So first order of business was for them to go put away their clothes in a bedroom, put on bathing suits and meet me at the pool for grilled hamburgers. I was cooking burgers wearing an unbuttoned Hawaiian shirt and cotton cut-off shorts commando style as usual when the girls came flying by me and jumped in the pool. I could just make out that they were wearing tiny white French bikinis. So they splashed around a bit and I told them to get out when the food was ready. They got out of the pool and walked over to me. The white bikinis were wet and translucent. You could clearly see their puffy little pre-teen nipples and the material on the bottom has working into their slits making revealing camel toes. “Holy shit!”, I thought. I caught myself gawking at them they saw where I was looking and just smiled. They sat at the table and I walked over to give them their burgers and the shape of my swollen semi-hard cock was clearly visible and wobbled from side to side. The girls stared openly, whispered and giggled. “What’s so funny?”, I asked. Christie said, “ We can see your thing!” “ Well what do you expect?”, I asked. “Those bikinis you are wearing are making me get hard!”. More giggles. It was getting to be night and I told the girls to go shower and get ready for bed. I went to my room to put on pajama bottoms with no top. I heard the girls in our master bathroom off the master bedroom. I called out to the girls, “ Why are you in my bathroom?”. They told me they liked the shower and jacuzzi tub we had. I went downstairs and sat in my favorite chair when the girls ran in and plopped themselves on the floor in front of the TV directly in front of me. They were wearing long t-shirts. They lay on their tummies with their feet in the air. Then as they spread their legs I could see they weren’t wearing any underwear!! As I stared at their pussies on display my cock began growing in my pajamas until the large shape of it raised up stretching the material taught. Christina looked back over her shoulder at me and said , “Can you see everything alright Uncle Tim?”. The she looked at my cock-tent, whispered something to Christie, she looked back at my cock and they both giggled. Just then my phone rang. It was Sharon and Beverly calling on Skype. I answered with a Bluetooth earphone in. They were in a hotel room. Sharon was holding the phone she was in her bra and panties. Beverly was walking around behind her with just panties on her big tits jiggling freely. “We just got settled in and are getting these uncomfortable clothes off. How are you all doing?”, Sharon asked. I turned the phone to show the girls lying in front of me with their pussies clearly visible and I said “You girls wave to Aunt Sharon and your mom.” They waved. Beverly had come to the phone too. “ Are you enjoying the show?”, Beverly asked. I pointed the camera to show my throbbing cock straining at my pajamas. “ Have you shown your cock to them yet?”, Beverly asked. I heard Sharon say to Beverly, “He likes the build up. He likes edging just almost ready to cum. He can keep himself hard that way for hours if he doesn’t get too excited. So he’s probably not gonna show his cock for a while. I mean he’s got all weekend. The anticipation is very erotic . It’s how his CFNM works.” Beverly said, “Wow that’s gonna be quite a lot of cum when the dam finally breaks!”. I said, “You’re right about that. I’m gonna try to hold out as long as I can. But your girls make my dick so fucking hard!” (more giggles from the girls) “Ha!”, Sharon laughed, “ Your dick gets hard every time the wind blows!”. So I told them good night with an agreement to Skype back regularly. I told the girls it was time to turn in. I couldn’t take much more of staring at those juicy young pussies so near to me.
The girls went to the guest room with bunk beds. I was too horny to sleep and dying to cum so I got naked, put on a porn video, got in bed and started slowly stroking my aching rigid dick. After a few minutes I heard a voice, “Uncle Tim?”. It was both the girls standing right beside my bed. Inches from my throbbing cock well illuminated by the TV. Christine was complaining that Christina was keeping her awake. Christina said she was having leg aches. I told her it was growing pains and we can go back to their bunk beds and I’d massage her legs for her. Both girls waited watching a naked girl sucking a huge cock on TV and me walking over to the TV to turn it off and to grab a robe while my rigid dick stuck straight out.
Christina got in the top bunk lying face down while Christie sat cross legged on the lower bunk. I started deep muscle massaging Christina’s legs starting at the ankles working my way up. Her firm muscular legs felt amazing. When I reached the velvety soft skin of her inner thighs she spread her legs further apart. Her t-shirt was up around her waist and she still had no panties. I massaged her perfect round ass. She moaned with pleasure. Then as I reached the wet lips of her pussy I suggested she lie on her back. She sat up, took off the t-shirt and lay down. I fondled and massage the mounds of her budding breasts. The puffy nipples were erect. She moaned with pleasure as I squeezed them. I worked down her tummy to her mons. In the low light of the room her pussy looked bald but I could feel the soft strands of a few blonde pubic hairs. When I reached her pussy slit she was dripping wet and her clit was swollen and fully engorged. She moaned loudly and thrust her hips and pushed her pussy into my hands. At that point I leaned over and began licking her clitoris and I slid my finger inside her pussy massaging her g-spot. It didn’t take long for her whole body to shudder with the first contractions of a combined clitoral and vaginal orgasm. She cried out and bucked wildly as the orgasms overwhelmed her and she squirted a large amount of her juices from her contracting vagina. While all this was going on I had completely not noticed that my robe had come open and my previously softening cock had become engorged with another raging erection that twitched and spasms inches from Christie’s face as pre-cum poured from my pee slit. At this point the bunk bed sheets were ruined and we were all covered in sex fluids. So we went to the bathroom and the girls climbed naked into the jacuzzi tub and I added some bubble bath. I sat nude straddling the edge of the tub with my horse dick standing straight up and my balls hanging down to the water. Then the phone rang again. Sharon and Beverly were Skyping back in. It seems they had picked up a couple of young guys, brought them to the room, had some disappointing fucking with their inadequate small cocks and thrown them out of the room. Sharon and Beverly then used a strap-on dildoe to fuck each other. They were both nude. Beverly was lying in the bed playing with her pussy after an intense orgasm. Sharon was talking on the phone in the familiar dreamy way she does after she has orgasmed hard but not quite done yet. “What are you guys doing?”, she asked. I set the phone down so they could get a full view of the three of us in the tub. Christie and Christina sat in the tub. I was in a wide man spread and they were between my thighs inches from my twitching cock. “Goddammit! Sharon said I wish we were there to share that donkey dick with you girls. Beverly got up to look and agreed with Sharon. As the two girls began exploring my dick and balls with their little hands I said, “ I wish you both were here too so the twins could watch me fuck both of you girls big titties!” Sharon convulsed with a last intense orgasm at the sight on her phone and squirted her juice all over the phone screen. After edging all day and night I finally let go a torrent of cum all over Christie and Christina. There were squeals of delight on both ends of the phone.
