My biological clock was ticking fast. I’m 26 and my womb felt empty. My sister Suzy is one year older than me and she has this cute 1 year old boy. I’m so jealous and take every opportunity to hold him. Suzy noticed my interest and asked me when I was going to conceive. I was caught off guard as she knows how much I want to become pregnant. All I could do was stutter. She told me to take matters into my own hands like she did. I lost my virginity at 16 because my body demanded a hard cock in my developing pussy and 10 years later my body is making fertility decisions. She said Mother Nature has demands and our boyfriends have to obey. I didn’t know exactly what to say, but I waited for her to continue.

With a wink in her eyes she asked me if I would like her to help with the “sting”. My face lit up with a big smile and I hugged her tightly. She said, this is June, you’ll be fertilized by August, I promise. Then she gave me some instructions- first chart my cycle carefully and note the onset of my periods and my mood swings and absolutely no birth control pills for this girl (I wasn’t on the pill anyway). I was to notice and point out every young hot mom and every cute baby. Next, make sure I buy some adult DVD’s that contain some young sexy MILF’s. She said there would be more, but for now it’s the start of the “Put a baby in sister’s womb” STING.

My body and my mind became preoccupied. All I could think of was my empty womb filled with baby batter then a real baby. I charted, I cooed babies and I bought the sexiest MILF DVD’s I could find and played them to jump start my sperm donor boyfriend, Bob.

At the beginning of August Suzy came to me to check my chart. She said the August 20th was my best time to catch and that we had to plan. First, no orgasms for him 4-5 days before the 20th. She told me to buy the sexiest Victoria Secrets demi push-up bra and thong. She said that red is the best color, kind of like a bull with a matador. Wave a sexy red number at a guy and watch him charge. I wear a 34B, so it was easy to find a selection. She also told me to shave my pussy as this eases the procedure. I picked out a low cup red demi bra and high cut thong. She asked me how important this baby was and whether we could use some trickery and some forcing, if necessary to obtain our sperm bath. I told her as long as Bob doesn’t have any long term pain or permanent injury anything we did was fine with me. My sister had other things to obtain and went about her needs list. She told me to prepare to receive the baby juice and ready the baby room. I could hardly sleep.

The morning of the 20th was sunny and perfect. Suzy called and told us she had gotten a babysitter and wanted to go to the beach with Bob and me. I said yes before asking him as I didn’t want him to say no.

By 11 AM we were at the beach. I wore this leopard skin string bikini and my sister who had delivered a baby last year wore a red bikini with cups that accentuated her 36C breasts. She flirted with my boyfriend and whispered to me not to say anything to him as the “sting” had begun and she wanted him unprepared and ready to deliver all his fresh load of baby milk. At 2 PM she announced that she had had enough sun and offered us something to eat at her place. (She wanted him in her web). Before we left the beach she gave me my final secret instructions.

As I enter her place my pussy was on fire and dripping lubricant. I knew that I would be filled with hard cock and hot cream any minute. My body was on fire and I had to keep quiet and not spill the plan. My sister suggested we use the bathroom in her bedroom to shower and she would use the guest shower. I quickly ran in the shower and washed off the suntan lotion and salt. My pussy was jumping with joy and my heart was pounding. When I came out my boyfriend went in for his shower. The stage was set, the “sting” had become and it was now my turn to start the end of his being a boy and the beginning of his being a father. I quickly dried my hair and put on the red demi bra and thong. I positioned pillows where his ass (and hopefully later, my ass would be propped up to hold his baby making sperm). My role was to play coy, innocent and encourage him to attack me. I removed his clothing from the bathroom so he would have to be naked leaving the bathroom making my job one step easier. Well, when my boyfriend came out in only a towel he saw me standing there with a sly innocent smile, he saw the red bra, saw my boobs hanging out, and he was all primed by the beach and bikinis and a 5 day load of cum. The male animal in him took command and he approached me and started kissing and caressing me. His big magic baby maker was at attention and poking out from the towel. It felt so good especially knowing he was going to make me a mommy with his special injection from an unprotected cock into a fertile unprotected pussy. My job was to let him play with my body but position him on the bed with his ass on the pillow. Funny, my body felt different; maybe it knew I was about to get fertilized, to become a mommy, to fulfill my destiny. My skin was on fire, my pussy was on fire and my skin was so sensitive. I have been told a hard cock has no conscience, but Mother Nature has programmed me to help reproduction, and my time was now. I remember when I was a virgin, my pussy took over at 16 and the next boy near me received the honor of my hymen. He thought he convinced me, but alas, Mother Nature drove me to accept a hard cock that night. All this was going through my head as he caressed me. I bent down and sucked his cock gently. My signal was the end of my sister’s shower, so I closed my eyes, said some words to myself, and kissed the head of the cock that was about to impregnate me. I pushed his ass down on the pillow and was about to mount Bob when he put on a condom. We had planned for this and I was to just jump on him and insert his condom covered cock and bounce carefully up & down so as not to lose his baby milk inside the condom.

Right on cue, my sister started into her bedroom with us engaging in the start of the baby dance. Riding him too long might cause a release of his baby batter. She was wearing only a towel and started to say, could she borrow a hair drier… She saw me riding his cock and instead of getting embarrassed she dropped her towel and asked to join us. As she came close she caressed my back and breasts, kissed me and then my boyfriend. She was stroking my shoulders then his, then my chest, then his. I later realized this was to get him used to her hands all over him as this might be needed later. She asked him if my tits looked good, perky and suckable. She lifted his head and forced him to suckle my nipple, just the thought of that caused me to cum hard.

She nodded to me that his time as a boy could be counted in minutes and he would be a daddy before the hour was over.

The final push “THE STING” had begun. She reached down between us and caressed his condom covered cock as I rode him. She said, “Wow your cock is so big and hard, I want to suck that baby”. She told me to get off him. I rolled over but kept my butt on the pillow and lay back. She smiled her sexiest smile and took his cock in her hands, rolled off the condom and started butterfly kisses all over his baby making tool. He was in heaven. I know he thinks she is the sexiest young mother and getting a blow job from her must have put his sperm factory in overdrive. Suzy rubbed his cock on her tits. She was careful not to bring him over the edge. I was so hot my fingers were on my pussy and could not stop stroking my clit. My sister gave me an eye message that we had one last hurdle and then “mommy time”. We needed him on top of me pouring his cock juice down my cervix.

At this point his little head was in control and he was so hot and horney his reason was gone, and as she stroked and scratched his cock I turned on my side and bent my leg so that my pussy was turned and open to his invasion. Softly she told my boyfriend to turn on his side towards me. Still scratching his cock just behind the head she moved his cock towards my pussy, and increased her scratching until he couldn’t stand it and his face contorted. I moved closer and she started rubbing his cock on my clit. “Baby, move over a little” was all she said, but her hands directed him to mount me in missionary breeding position, and at this point he was entering a fertile unprotected pussy with a bare cock ready to deliver million of solders ready to do battle with my egg. Once he was in the saddle, with swollen balls and prostate full of magic baby juice I could start charting my delivery date. My boyfriend looked at me realizing that he might be making himself a Daddy, but his instinct and hardness forced him to proceed. Suzy patted my ass which was a signal to start thrusting my hips and pulling and squeezing this beautiful cock that would make me a mother. She also patted and directed Bob’s ass up and down in the classic rutting motion. My sister was in no way done as she knew many things might cause him to stop and as she told me, once insertion had began the cock would not leave my pussy until he had done his reproductive purpose and left behind all his creamy cum. So she continued stroking him and whispering things like “good boy, good boy, let it out, let it out, cum for me………make a BABY”. I had one job to keep kissing him so that his mind was occupied and roll and thrust my hips so his cock was occupied reaching the end I so long wanted. All of a sudden his face left my lips and was buried in the pillow, his hips were still rutting, but he kind of slowed down and he started to say something like, wait or stop he knew what was coming soon, namely him and he realized he would impregnate me. He said he wasn’t ready to be a daddy, I told him that no male is ever ready, but tonight was his time. He said he wouldn’t cum and would hold out. I told him if he can stay calm and not squirt his magic juice he’ll be fine. He started straining not to cum so I looked at Suzy and moved the top of my body away from Bobby as I knew what would be next and all the weight on my chest would suffocate me. I saw her reach below the bed and grasp an object; I later realized it was a well lubricated small size vibrating butt plug. She was behind him and he didn’t see her, she smiled as she turned it on and in one swift movement inserted the butt plug in his ass and at the same time threw her body on his back with her knees on his upper thighs so he could not withdraw from my vagina nor remove the butt plug. His body jerked and convulsed as the vibrator massaged Bobby’s prostate. His cock was at the deepest point in my vagina, I stopped moving and the weight of Suzy kept him deep. He tried to withdraw, but with Suzy laying on top of him with her knees positioned and having no leverage he was stuck deep. He squeezed his muscles and tried to hold back his orgasm. All that did was increase the pressure on his prostate and when he blew the soldiers shot deep inside me almost straight into my birth canal. He could no longer hold back his cum as the vibrator on his prostate did its magic on him and the flood gates opened. He delivered the freshest baby making milk deep on my cervix. The flow continued for several minutes and my sister kept up the pressure to insure a full release of the ejaculate and insure proper conception. He muttered and moaned and seemed to be in great pain, but my sister warned me that sometimes a woman in heat wanting to make a baby needs to take control and not wait for some guy to decide when (if at all).

Fertilization completed we waited until Bob started to shrink, Suzy grasped Bob’s manhood and stripped off the balance of his sperm into my pussy as he withdrew. Bob rolled off me and was entirely exhausted. Suzy grasped a pocket rocket and placed it on my clit encouraging, no demanding, an orgasm to force my cervix to dip into the DNA pool and insure impregnation. Suzy whispered to me to lie on my back with my hips on the pillow and fall asleep to allow the baby batter a downward journey. She also asked if I would mind if Bob gave her a ride as she was horney as hell as things developed. I smiled, kissed her and told her thanks, he’s all yours.

Suzy is smart, all she did was get in bed naked beside a sleeping Bob facing him, and a few hours later I awoke to feel the all familiar rocking of the bed. She told me that Bob had stirred and felt her beside him. She encouraged all his caresses not wanting to be coy. She welcomed everything he had to offer. Luckily she was on the pill and took him bareback. It is amazing, hours after having been forcibly mated he still had enough stiffness to give Suzy a complete and proper service. Once you have a guy in the mating mood, hot and ejaculating, it is easy to make him a breeding stud. In the morning she told me to get into doggy position and helped a sleepy Bob get behind me. The baby dance continued for another round, except this time Bob released his nectar without any difficulty.

Oh, yes I failed badly the EPT test 2 weeks later and my belly began getting rounder in October. I delivered in May and breast fed my baby, Bobby even sucked me. I kept Bobby busy sexually role playing and wearing sexy outfits as my weight decreased and my figure almost returned to my pre baby size (except my titties grew from a “small B to a small “C”)”. My sister told me for a woman wanting to get pregnant, the “sting” never fails and Bobby just walked into our lair. Bobby my new daughter and I are still together, he’s a great daddy.

Now a word of advice to the guys out there, don’t think you are immune to “The Sting”. When a girl is in the breeding mood, no man can stop her. Mother Nature has a special way to develop our breasts, our hips, then our pussy’s and finally our wombs. So be ready to deliver your seed upon demand, or keep celibate and pleasure yourself. That’s the only sure way to prevent becoming a daddy. Given an opportunity, any female will place you in the saddle and ride you until you deliver the fluid into her baby making factory.
