I’m pushing hard on her arousal switch and sense that she is getting close. She is doing her best to hold back moans of pleasure, but between my skill and the switches, she doesn’t stand a chance. I sense the exact moment and give her stiff nipple a sudden twist. A loud moan escapes from her clenched jaws, and my hand is covered in her fluids. I rub hard back and forth against her, trying to make her climax last.
"Look at your brother’s erection," I tell her. "See that liquid seeping from the tip? That’s because he likes what he sees. You turn him on." I can hear muffled denials, but her eyes are glued to James’s arousal.
"I’ll bet you’re wondering what it would be like to have him inside you." I make a switch to make the inside of her itch. "Or maybe even taste him." Her mouth goes dry after I make and move another switch.
My erection is nestled between her small buttocks, and I begin to grind slowly against her while resuming my assault on the rest of her body.
Her denials grow weaker, and by the time she reaches her second climax, she is no longer resisting my words.
"See how his fluids are running from the tip of his penis? That’s all because of you, his dear twin sister. He wants you. You can see it in his eyes. See his hunger, his desire. I can tell you like him looking at you. I can feel how wet you are down here. I know you’re thinking about what it might feel like to lie with your own brother."
This time, the sound that escapes her throat is one of acceptance.
"But wait... isn’t that a sin?" I rub her harder, tweaking her nipples and nibbling lightly on her neck. She is completely confused. Her body is telling her one thing, but her mind is saying something else. "How can it be a sin, though, if you love each other? You do love your brother, don’t you?"
Carefully, I lessen the switch that’s holding her paralyzed, ready to reinstate it at a moment’s notice. I needn’t have worried.
"Yes," she whispers, then moans as I turn up the sensitivity in her clit and nipples. "I do love him," Jessie moan out.
Her hips are now moving, grinding her ass against my rock-hard cock.
"You know," I whisper conspiratorially, "while he’s frozen like that, I’ll bet you can find out just what he tastes like, or even what he feels like inside you." I fully release her and step back.
Hesitantly, she looks from me to her brother’s cock. It’s easily apparent who is better endowed, but love wins out, and she rushes to James.
Dropping to her knees, a tentative hand reaches out but stops before making contact. "Forgive me, James. I—I can’t help myself. I’ve always looked up to you, and I love you so much. Please... please forgive me, but right now I need this." Her fingers close the final distance, and I swear she moans as she makes contact with her sibling’s phallus.
There is a flash of light behind me, and I spin around, prepared for an attack, but it’s only Stephanie. A very naked Stephanie.
"Sorry to scare you, but I saw how hard you are and didn’t want to pass up this chance," she tells me, a twinkle in her eyes. "You’re still going to hell, though," she said.
I know she also doesn’t want me trying to have sex with the slight redhead as well, but I don’t mind. I’m so aroused right now that I just want to take her down and have her on the dry desert floor.
A muffled moan brings my attention back to the twins, and I see Jessie has James’s shaft between her lips, sucking up his precum. James’s eyes are closed, and I know he is enjoying the incestuous liaison. I decide to turn off her dry-mouth switch. She seems to be satisfying that urge.
Warm lips wrap around my own shaft, and I let out my own moan. Looking down, I meet Stephanie’s grinning, lust-filled gaze and smile as I run my fingers through her hair.
"James, I know you would stop me if you could," Jessie says then, and I see she’s gotten to her feet and is looking her brother in the eyes. "But I have never wanted anything as much as I want this right now." She gives him a tender peck on the lips, then turns around and backs up to her brother’s rigid length. I can see she’s trying to guide him inside her. There is no mistaking the moment she gets it right. Her eyes pop open wide, and I hear one of the most seductive moans ever leave the true redhead’s throat. "I never knew what this could be like," she mewls as she starts to really move against his now slick length.
Stephanie’s lips leave me, but only long enough for her to bend over in front of me, mirroring Jessie. I immediately take a half step forward and thrust into my girlfriend, making us both moan at the joining of our bodies.
Our moan gains the twins’ attention, and I even notice Jessie smile before she begins to shudder in another climax. Looking into James’s eyes, I can tell he is enjoying this as much as his sister, and I release him.
Once again, I’m wary, and once again, I don’t have to be. James grabs hold of Jessie’s hips and starts thrusting violently into her, making Jessie grunt with each impact.
"Oh, Jessie," he calls out, "I know it’s wrong, but it feels so right! I love you, sis!" Then he grunts, and I know he’s climaxed inside his sister.
"I think it’s time you two came back up to the ship," Loveth sends to me, and suddenly I’m back aboard Vage’s vessel, still having sex with Stephanie, but now surrounded by three other naked women. Smiling, I’m excited about how good this night is going.
