She had achieved paradise.
All around her, people bowed to her. They worshiped her like a goddess. The entire planet looked up to her as a guide to the future; their prophet. She could get anything she wanted with no consequences. The sun and the moon rose and fell with her. The whole world became her slaves and she enjoyed every minute of it.
And her sister was the cherry on top of this delicious cake. And she took that cherry.
Blackfire smiled as her sister gracefully danced around the bedroom they owed. As much as Blackfire preferred to have the opinion that she was the better of the sisters, she agreed that her sister had the better body. So slim, with well defined curves. Blackfire made a good choice of outfits; all of them containing just enough fabric for public decency, but a simple gust of wind could make her naked. With all the sweat she was building up thanks to the dancing, her perky nipples and shaved womanhood could be seen through the fabric.
"So lovely." Blackfire claimed.
"I practiced all day for you!" Starfire huffed out, while shaking her well-rounded rear directly at her sister.
Weird thing about Starfire. Once, she hated Blackfire. She committed many crimes and blamed on Starfire to escape law enforcement. The next time the two met, Blackfire had taken over their home planet and got Starfire engaged to a disgusting…thing. In the end, Blackfire got arrested and married to the thing. It took a year to break it off, and an extra year to get rid of the smell.
At first, Blackfire wanted revenge. Kill her sister and her merry band of friends. Then put their heads on a pike for the entire world to see. But her mind went from wrath to lust as she discovered some racy pictures on the Internet. Apparently, most of the Titans became perverted sex-fiends during the time it took her to escape the green thing. Starfire's fetish happened to be webcam stripper.
And her biggest fan was one 'DarkSun515'.
For the next six months, Blackfire paid for private shows so she made her sister do what she wanted. (With money stolen from various banks across the galaxy.) At first, it was revenge. Make her sister do embarrassing things for her amusement. Then she started to enjoy more than a joke. She would make Starfire live out her sexual fantasies. In the end, Blackfire asked for a date.
Blackfire wanted Starfire for herself. Robin was still around; while the two weren't dating, Starfire wouldn't, under any circumstances, date or even hang around her own sister.
So Blackfire cheated.
She used a drug she bought off the Tarklain Black Market. Before Starfire arrived at the apartment Blackfire rented, Blackfire put the drug into a cup meant for Starfire. When Starfire arrived, she tried to leave, but Blackfire pleaded her life and her innocence. It was demeaning, but it convinced Starfire to stay and have at least one drink with her.
And that lead to a wonderful new life. With Starfire under her control, Blackfire was able to take control of their home world.
Starfire approached Blackfire, taking off her clothes slowly. Blackfire licked her lips in anticipation. Blackfire took Starfire's breasts in both hands and played with them. Starfire moaned in absolute pleasure. Amazing thing, that drug. When Robin tried to do the same thing, Starfire yelped in pain. Now, only Blackfire could even touch Starfire to make her feel good.
Blackfire opened her mouth and started to suck on the left breast like a baby. Speaking of which, Blackfire drew her mouth away for a second to say something.
"Tonight, I'm going to impregnate you."
"You are?!" Starfire asked in complete joy. "Oh, today will be the best day of my life!" Starfire then turned around and used two fingers to open her womanhood.
"Not yet, dear." Blackfire whispered. She shoved her sister onto the bed and pounced on top. Their vaginas touched; Starfire's bare flesh to the barely clothed Blackfire. While Starfire breathed heavily, Blackfire took off her clothes and laid her naked form on top of Starfire. The two locked their lips together and started a war of the tongues.
"Let's get you wet." Blackfire giggled. Starfire spread her legs out as Blackfire moved down to eat out. While Blackfire licked and bit at Starfire's vagina, Starfire tweaked her nipples. Blackfire knew how to make Starfire curl up in pleasure, and it didn't take long for her to cum. Before Starfire could have a chance to recover, Blackfire jumped onto Starfire's face and moved her vagina above Starfire's mouth.
They moved in motion together. Starfire's tongue followed the swaying of Blackfire's body. Blackfire bit her lip, used one hand to massage her left breast, while using her other hand to finger herself along with Starfire's tongue. Starfire treated Blackfire's womanhood like a chocolate lollipop with a sweet creamy center. Starfire licked away the cum while Blackfire gathered energy in her hands.
"Ready for the babymaking?" Blackfire purred.
"Yes…" Starfire lavishly asked, as she spread her legs out wide and held her vagina open with four fingers, two on each hand. Blackfire grinned, and with the energy in her hands, created a glowing penis that reached seven inches long. Starfire giggled at the size of the penis as Blackfire wagged it around, testing its strength to see if it stuck on.
"Works like a charm." Blackfire proclaimed. "This puppy will take my excrement and turn it into sperm loaded with DNA and shoot it inside." Blackfire put her new penis near the opening of Starfire. "So, any female who knows the spell and has the power can impregnate any other female."
"Can I later on?" Starfire asked with her eyes wide open in hope. Blackfire took a second of tapping her finger on her chin to answer.
"Nope." Blackfire politely answered before plowing Starfire all the way through. Starfire screamed out her joy as the magic penis started to fill her body with hormones. Blackfire grabbed Starfire by both legs and pounded her with swift hard blows. Blackfire started to drool, seeing her lovely sister enjoying every second. Her breasts bounced up and down, her mouth hanged open in a large smile, her eyes rolled back, and her arms unmoving.
"I…love…you…" Starfire muttered out.
"I love you too…and I want to expand my love." Blackfire said as she hammered Starfire. "Here I come!"
Blackfire exploded inside Starfire, impregnating her good as her entire uterus got filled with hot, steamy seed. Blackfire started to laugh as Starfire fainted from the intense pleasure, a smile still plastered on her face. Blackfire took a minute to relax and let the magic penis vanish. After catching her breath, Blackfire cleaned off the remaining cum and tucked Starfire in bed before climbing in herself.
The next month would confirm Starfire was indeed pregnant with Blackfire's child. Starfire was so ecstatic, she stopped wearing clothes for a entire month, much to Blackfire's delight. In fact, once Starfire started to show pregnancy, the sex got even better!
Blackfire considered dealing with more children just to do this again…
