After Deana and Evan left, Rebecca stripped and stood in front of the mirror, holding her pussy. It was the same pose she had taken the morning after she and Deana crossed the invisible line that had kept them from doing what they both secretly wanted. They had spent the night together, making love, then Evan came to get Deana, and Rebecca imagined the best of both worlds, a threesome with twins. As impossible as it seemed, the way Deana told the story about Evan’s dick getting hard under her foot made Rebecca think it might be possible. With a bit of planning, some subtle hints, and a few sexual innuendos, maybe it would happen.

That day, the nasty fantasy about Evan fucking Deana was enough to get Rebecca off, but she had wanted more. She wanted Deana, a friend with benefits, but Rebecca liked dick, too, and she wanted Evan’s. Fucking twins would be out of this world, crazy exciting, Rebecca had thought.

When Evan grabbed and felt up his sister’s ass in the school parking lot under the pretense of judging who had the best butt, Rebecca thought her plan might have merit. When they agreed to kiss in front of her, she felt her stomach tumble. The sight of the twins kissing set her mind on fire. Then, as if all the planets lined up in favor of her desires, the twins got lost in each other, and their breathing turned to pants and gasps. Rebecca heard the passion from their lips and tongues and saw the urgency in their groping hands. They were on fire, ready to rip each other’s clothes off and fuck, and that had been enough to make Rebecca cum.

After, Rebecca made Evan sweat and lick his lips while she spread her legs behind Deana’s seat, showing off her wet pussy. That was when she was sure it would happen; Deana would let her brother fuck her, and Rebecca knew she could get him to fuck her, too. Still, that wasn’t enough. She wanted more.

A lot had changed since the day Rebecca left the juicy evidence of her lust on Evan’s backseat. She still wouldn’t label her sexuality, but she had fallen deeply in love with the tall, olive-skinned Italian girl. She loved Deana so much that it hurt when the girl left. She thought of her while they were apart, and even though she had orchestrated it, swore it didn’t bother her, and promised never to be jealous, Rebecca fought tears whenever Deana talked about making love with Evan. It wasn’t the sex that made her jealous, not really. They lived together, shared everything, even each other’s feelings, and sometimes they saw each other’s thoughts. Their love connection seemed to supersede anything possible in a normal relationship. That’s what Rebecca was jealous of and why Deana’s gift was the most meaningful birthday present Rebecca would ever receive. She’d remember it until the day she died.

Deana had given her the most precious, beautiful, and powerful thing she had. The love the twins shared poured into Rebecca while Evan climaxed. Sperm blasting her cervix should have caused a panic, but it didn’t because Rebecca had been the center of a love sandwich, sharing the one person Deana loved more than her. Now, Rebecca grinned at herself in the mirror, crossed her legs, and tightened her thighs against any chance of Evan’s cum escaping.

When Evan and Deana got home, she waited for him at the bottom of the porch steps and said, “If Mom happens to be in the kitchen, do something to distract her so I can get to my room.”

Evan grinned at the pink crowns swelling under Deana’s Georgia Peaches T-shirt. “I thought you weren’t worried about Mom?”

“I’m not worried, but I’d rather not entice her with my sexy body,” Deana said. “Not today.” She took the first two steps in one stride and leaned forward until the smiley face creases under the bubbles of her butt showed. “Oops.”

“You’re lucky we just did it,” he said, catching up to Deana.

She slinked up against him like an affectionate cat. “Why am I lucky?”

“Because if we hadn’t, Mom, seeing your scantily clad body would be the least of your worries.”

“Mm, you’re right,” Deana said and reached between his legs, “because I’d let you take me right here.” She palmed his balls and slowly drew her hand back.

Once the quick shiver-jerk passed from Evan’s shoulders to his neck, he reached under Deana’s shirt. The cum drooling from her lips reminded him. “What you said before, you didn’t mean like now, did you? Rebecca is—”

“Relax, it’s just a dream, for now. She has PlanB, so no worries.” Deana put one foot on the next step up and blew out a long breath. “Fuck, the two of you have turned me into a sex-crazed animal. I already want you again, right now.”

“Well, you’re in luck,” he said. “I’ll meet you in the shower after I distract Mom from your incredible body.”

Deana quickly took the last couple of steps, swung the screen door open, and flipped up the back of her shirt. “Bring her with you.”

That would be a dream come true, Evan thought. “You wish.” His sister didn’t respond, but her face told him she wasn’t kidding, and that made him think about Deana’s words, “I don’t think it’s a man.” Did Deana think Candy was in love with her? Nah, he dismissed the thought as Deana left without him. So much for being worried about their mother seeing her ass hanging out.
