Tim came home that night about one o’clock. He came into the house quietly and crept silently up the stairs. He stopped by his sister’s room, but Traci wasn’t there and her bed was still made up. He mentally shrugged and left her room.
Looking down the hallway, Tim saw his mother’s bedroom door part way open, but he didn’t see any light or hear any noise. The house was totally quiet, except for the occasional creaks or groans that houses give off. He didn’t know what Traci had planned for tonight. She had just told him to stay away until at least midnight. Now she wasn’t here. He wondered what was going on.
Tim went into his bedroom and quietly closed the door. He got undressed and was pulling back the comforter and sheet on his bed when he realized that he should probably go pee before going to sleep. Opening his door, quietly again, he walked down the hall naked, mentally daring his mother to come out her door and see him. He was pretty sure that wouldn’t happen, but the thought excited him and by the time he closed he bathroom door his cock was beginning to swell.
He peed, lowered the lid and flushed the toilet. He wondered if the noise would wake his mother. Probably not, he thought. He had done it late at night many times before when his mother was sleeping. And, if it did wake her, she would realized what it was and then go back to sleep.
Tim was back in his room, under the sheet when he heard his door open. He saw a shadow of a silhouette closing the door carefully.
“Traci?” Tim called out softly.
“Yeah,” she answered. She silently made her way to his bed and slid in beside her brother and cuddled her naked body up against him.
Tim was surprised, but pleased. “You weren’t in your room…” he began.
“Right. I heard you flush the toilet and thought I would come and give you a progress report.”
“You heard me flush the toilet? But, where were you.”
But Traci was giggling and kicking her feet.
“What the hell is so funny, Traci?” Tim asked with a bit of exasperation.
“I said that I came to give you a progress report. Our family name is Pilgrim. That would make my report ‘The Pilgrims’ Progress.’ Don’t you get it? Although I’m sure that John Bunyan would be scandalized by our type of progress.”
“No, Traci, I don’t get it,” Tim said in a hissing whisper.
“Oh right. I’m the English Lit. major. But, surely you’ve heard of “The Pilgrim’s Progress,” by John Bunyan?
“Actually, no.” Tim folded his arms over his chest and stared at the ceiling.
“Oh, now don’t get all huffy on me.” Traci was still smiling as she propped herself up on her side to look Tim in the face. There was just enough light coming through his window to make out his facial features. “I have good news. I have made progress vis-à-vis you and Mom having sex.” She wiggled her eyebrows lewdly at her brother.
Tim rolled onto his side, his eyes wide open. “You have? Really?”
“You bet your ass, I have. So, you can kiss me now.” Traci said with a note of triumph in her voice.
Tim pulled his sister tight against him. Her face was little more than a faded shadow since the window was behind her. His lips carefully sought and found hers. He gently sucked on her lips, teased her tongue from her mouth with the tip of his then closed his lips over his sister’s and kissed her for a long time.
“God, Tim,” Traci gasped when their lips parted, her heart beating faster, “we must have kissed a thousand times and I still love it. It gets me all excited and wet… kissing my twin brother.”
“Me too… well, excited and hard, not wet.” Tim paused a moment as they kissed some more, lightly. “So tell me. What happened? What did you do?”
“Tim,” Traci started out obliquely, “have I mentioned that I’m bi-sexual?”
“Huh? What? No.” Tim was wondering what Traci was getting at. But a part of his male mind was revving up with images of Traci kissing other girls and not just on the mouth, either. His dick, which was already half hard, began to become fully erect.
“Well, it just so happens, Tim, that Mom is bi-sexual too.”
“Whaaat?” Tim wasn’t sure what he was hearing. He had spoken rather loudly. Then he lowered his voice, whispering, “What are you talking about, Traci?”
“Oh don’t worry about Mom hearing you. We had quite a session. I mean it was fucking fantastic. She’s sleeping soundly. I was waiting for you to come home. I was excited and wanted to tell you about it. Still, I was just falling asleep when I heard you in the bathroom. I barely woke up.
“But,” Traci continued, “I caught Mom making love to two different women on two different occasions.”
“You’re shitting me.” Tim was totally shocked.
“No I’m not shitting you, Tim. The thing is, I saw her but she didn’t know that I saw. That’s why I wanted you out of the house tonight. We were on the couch, Mom and I, watching a movie, cuddled up, all mother and daughter like, then I asked her what it was like to kiss a girl, because, well, a girl at school had come on to me and I was wondering what it was like.
“At first she was like, what, why would you ask me that. Then I told her that I had seen her making love to two other women. To make a long story short, Tim, I seduced Mom. We went to her bedroom and made love to each other until we were exhausted.”
Tim’s cock was at its full, vein-bulging hardness. His cock head was as big and firm as it had ever been.
“Far fucking out,” Tim said, trying to imagine his sister and mother licking each other’s pussies. “But,” he thought about what his sister had just told him. “Are you… I mean, was that the first time you….”
“Oh no, Tim,” Traci interrupted. “I’m bi’, too. I’ve done it with three other girls. Not all at once, you know. Different times. So I was, you know…. Well, I lied to Mom. But for a good cause, don’t you think?”
“Uh, yeah.” Was all Tim said. He was imagining his sister licking pussy… other than their mother’s. Damn! He thought. Traci and Mom licked each other’s pussy? Oh my God! It felt like his cock got harder, if that was possible.
“I also told her that we were lovers.”
“ Ooo! How did she take that?”
“What could she say? We had just made love to each other. She accepted it.”
Traci, who thought that her brother might just get a nice big stiffie out of hearing about what she had been up to with their mother, slid her hand down his body to his groin. She wrapped her fingers firmly around his erection.
“Oh my, Tim. You have a present for me?”
Tim pulled his sister over on top of him. They maneuvered until his cock head was positioned to enter her very wet pussy. Traci moved her hips back and sighed with pleasure as Tim’s thick cock filled her.
Tim sighed with pleasure as his cock entered his sister’s slick, warm, and oh so tight pussy. Brother and sister began fucking, meeting each other half way. Not fast. Not hard. Just ever so pleasantly.
“So then what. You and Mom made love, but….”
Traci leaned forward and kissed Tim on the lips. “And then I told her that you wanted to fuck her, and that she would be a fool not to, since she had just fucked her daughter, and, well, after a moment’s reflection, she agree.”
Tim groaned loudly. His hips heaved up against his sister and he was coming, hard, intensely. Traci rode it out.
When he was done and had recovered somewhat, with his cock beginning to soften, still inside his sister, he said: “Sorry, Traci. It’s been at least two days since we last fucked and what you were telling me was just so exciting.”
“That’s okay, but there is a small problem, brother dear.” Tim saw Traci’s teeth flash palely in the dark. “You see, I was looking forward to your lovely cock fucking me and making me come. But since you just came, well, why don’t you go down on me and lick my pussy and make me come that way.”
“But I just came in your pussy,” Tim protested.
“So what’s your point?” Traci was trying to sound tough, but she was still smiling. “Your cum can’t be poisonous. I’ve swallowed several of your loads this last month and I’m still here, hale and hearty.” Traci was having a hard time suppressing her giggles.
“You created this mess,” Traci continued, “so, please, brother dear, clean it up. Lick my pussy and give me the pleasure that I deserve. After all, I did get Mom to agree to fuck you. That’s got to be worth something, eh?”
Tim mentally shrugged and rolled his sister off of him. His cock was dripping with her juices and his cum. He positioned himself between Traci’s legs and tentatively lowered his face to her pussy. He could smell his semen. He mentally shrugged again and began to slowly, carefully lick at his sister’s pussy. He couldn’t detect any specific taste. It just seemed as though Traci’s pussy was wet with a thicker, slicker fluid. He began to lick her more earnestly now.
“Ohhh! Tim!” Traci breathed out quietly. “Yes, Tim. Oh that’s so good.” She was a little surprised that she was able to talk her brother into licking his cum out of her pussy so easily. She was even more surprised at how excited it made her.
Traci grabbed her brother’s head in her hands and pulled him hard into her sex. She pushed with her vaginal muscles to get all of his cum out of her pussy onto his tongue and into his mouth that she could.
Tim really got into licking his cum from his sister’s pussy because of her strong excited response to what he was doing. Her excitement, that he was giving her pleasure, excited him. He loved giving his sister pleasure and this, obviously, was giving her a whole lot of it.
“Oh, yes, Tim! Sweetheart! Lover! Oh God Tim I’m going to come!” Traci said in a loud whisper as she pressed her pussy hard against her brother’s mouth. The climax swept through her body in waves, taking her strongly.
In a few moments her body had relaxed and her breathing began to get back to normal. Tim had moved up beside her. “Wow, Traci! You had a good orgasm,” he said.
Traci’s fingers traced the side of her brother’s face. She kissed him sweetly. “No, sweetheart. I had a wonderful orgasm. Thank you, Tim.”
“Ah, my darling. How can I thank you for all the pleasure you’ve given me. Oh, Traci, I really do love you, you know?
“Yes, Tim. I know, because I really do love you too.
“And I don’t know what we are going to do about that, as you said before,” Tim continued, “but I know we’ll figured something out. Because I don’t ever want to be without you.”
“Oh Tim!” Traci cried and kissed him fiercely. “Yes. Yes. We will figure it out because I don’t want to be without you either.
Brother and sister kissed sweetly for a while, cuddling close together, caressing each other gently. Then Tim pulled the sheet up and they fell asleep in each other’s arms.
