As Christian gazed down lovingly at the girl of his dreams, he also felt a growing animal lust and passion radiating from his cock.
"I think that I still owe you one from downstairs, don't I?" Christian asked with a half smile and raised eyebrow.
"Hmmm…I wouldn't say that you 'owe' me one, since I loved the taste and feel of your cock and cum in my mouth. But I suppose if you said that you wanted to reciprocate in some way," Tiffany said, moving her mouth right next to Christian's ear, licking it, and then whispering, "I'd tell you that you can do anything that you'd like to me."
Then, moving back and bending her head down slightly, she looked up at him with her big, innocent blue eyes, her subtle patch of freckles lying underneath and, in a soft voice, repeated, "Anything."
Christian felt his heart skip a beat and nearly came in his pants as he looked at the doe-like schoolgirl standing before him. In a flash he was kissing Tiffany again, their tongues tearing into one another's mouths in a vain attempt to fully express their passion. Soon Christian's hands had moved from Tiff's waist and were now fondling one of her full breasts and tentatively stroking the length of her rigid penis, causing her to let out a tiny, desperate moan into his mouth. Tingling with pleasure, Tiffany's own hands began to work on Christian's belt.
After several more minutes, Christian broke the kiss and, taking Tiffany by the hand, wordlessly led her over to his bed. There, he bent down to scoop her up into his arms, smiled while he looked into her eyes, and laid her form on top of his covers. He then quickly removed his shirt and the rest of his pants and boxers and then positioned himself over top of his love. Their bodies pressing together, they once again fell into a kiss, one still laden with passion, yet fuller, deeper, and more delicate than those previous. Gradually Christian began to kiss down her neck, lightly sucking an biting, eliciting moans of pleasure from the girl's throat. As he reached her full breasts, he marvelled at how long and hard her nipples had become; each protrusion was completely erect and nearly an inch in length, something that greatly intensified and facilitated his suckling.
"Do you like me sucking on your tits?" Christian asked teasingly as he rubbed his lower lip along the apex of Tiff's right nipple.
"Mmmm…," Tiff moaned in reply, her words accentuated my gasps and changes of pitch. "Yeah, I love you sucking on my, mmm, tits. Oh…my nipples are so hard for you right now…mmmmm…and so is my big, fat cock….oh, yeah….mmmm…I want you to suck on my cock, baby….yeah…I want to stick it in your mouth and…and…fuck your face with it…oh, fuck!"
Christian's cock throbbed with every dirty word that came from his love's mouth. He never would have expected her to say such things! Marvelling at how lucky he was to find such a prize, he left her magnificent tits in search of an even greater prize: the enigma between her luscious legs.
Sliding down the bed, Christian positioned himself so that he could get a good look of what lay between this girl's legs. Sensing this and wanting him to look, Tiffany spread her legs out wide, allowing him an unhindered view. Fundamentally, she had an entirely normal looking vagina anus, and perineum, but simply had an average-sized cock (5.5" long, 4" around) protruding from immediately above her clitoris; the only thing that appeared to be missing was a scrotum and her testicles. Her vagina lips were quite full and hung slightly away from her body, and she had a modest patch of dark pubic hair surrounding both sets of genitals, both of which turned Christian on.
"From what the doctors that treated me when I was younger gathered, and I agree based on my own research, the embryonic tissue that normally forms either the clit or the glans of the penis basically split in two for me. From there it must be just the dumb luck of my genetics: I must have produced enough testosterone to grow a penis, and yet must have lacked the gene needed to form my testicles or to make me genetically a boy. Since I'm otherwise exactly like a female inside, I produce normal amounts of estrogen that gave me my breasts, lack of body hair, and other secondary female sex characteristics. The rest I'm a bit shaky on, though: I must have some sort of modified duct system inside, since I urinate out of the urethra in my vagina like a girl, and yet I still have a penile urethra, and I still ejaculate from my cock when I masturbate it. I guess I must have some sort of modified prostate gland and bulbourethral gland inside somewhere."
Blushing, Tiffany continued, "Sorry, but I did come over here on the pretence of studying biology."
Laughing, Christian asked, "So, you're basically just like any other girl, except you have a penis and somehow have the ability to ejaculate from it?"
"Pretty much," Tiffany replied, smiling. Then, becoming somewhat solemn she said, "The one thing is that I won't be able to have any children, though. When I was having tests done as a child, they basically determined that I was going to be sterile."
Having by this time moved up the bed to lay beside his love and hold her in his arms, he asked, "How do you feel about that?"
"Well," she began, "it does make me sad in a way, but at the same time I'm okay with it, and somewhat relieved. I know that my genetic makeup is pretty unique, and I would hate for that to ever jeopardize my well-being of my baby. Also, there's sort of the social aspect of possibly having an androgenous boy or girl, which is something that I've been dealing with for the past 18 years." "I know that my future husband and I would love any child that we had, but I don't know if he or she would have the same luck that I've had recently," Tiff said as she smiled at Christian. "In any event, though, it pains me that I can never give birth to a child myself, but I know that I can always adopt and love that child just as much as I would have my own."
Gazing at the girl before him as she spoke with such grace and maturity, Christian felt a shiver run up his spine.
"You're beautiful," he said. "And I love you for it."
Seeing the truth of his statement in his eyes, and reflecting it with he own heart, Tiff replied, "I love you, too, Christian."
The pair embraced, just holding one another and feeling their hearts beating as one. Eventually, Christian pulled away and kissed Tiff softly on the lips. He then gave her a wicked smile and began kissing her neck and breasts again, slowly making his way down to her pubic region. Within no time Tiff's breathing had picked up to where it had been before, and she knew that she wanted this boy in front of her badly. Her rigid cock was aching for attention and she saw that it had a drop of precum leaking from its tip. She could also feel that her pussy was sopping wet and desperately needed a cock inside of it. Fortunately for her, there was a boy on top of her who was more than ready and willing to fulfill such desires.
Although Christian had never sucked on a cock before, he'd read about and seen enough of it to have a pretty good idea as to what to do. He began by licking the shaft all over, paying special attention to the head and urethral opening.
"Mmmm…that feels so good, baby," Tiffany encouraged, loving the new sensations. "I know it sounds slutty of me, but could you spit on my cock, please? I just want it to feel all nice and slippery when it's sliding in and out of your mouth."
Greatly turned on by her words, Christian complied and spat some of his saliva onto her cock. He allowed it to run down the side that was facing her to tease her and to play on her fantasy. Watching her face, he saw her eyes glaze over even further with lust before he attacked her penis with a fury. Being careful not to graze his teeth along her head, he took the lubricated cock as far into his mouth as he could before he felt a gagging sensation in the back of his throat. Half-expecting it, he sought to relax the muscles in the area and let her tool in even farther. Sure enough, the gagging sensation passed, and he bobbed his head up and down the shaft, causing Tiffany to cry out in pleasure. Happy that he was on the right track, Christian began to experiment with different rates and depths of his blowing Tiff, alternated with just jerking her off and licking her penis head.
"Shit, baby…I think I'm going to cum soon!" Tiffany cried as she felt the spasms in her loins become ever stronger.
