Joe texted Hannah when their mother was dressed again. She hurried into the apartment, with a grin from ear to ear.
"Hannah, sweetie, you must have had a good day. You're smiling like you're on top of the world," Julie said, hugging her daughter and kissing her cheek.
"I got a good grade on a test, and I'm just glad to see you!" Hannah replied. She glanced around the apartment. "I see you've straightened up some things. You know that's really not necessary. We can take care of ourselves - but it is so nice for you to visit, anyway! Want to go out to eat?"
"Oh, I guess I better get on back. You coming home Thursday afternoon? How do you manage to get all your Fridays with no classes?"
"Just lucky, I guess. I don't know that I'll always be able to do that," Hannah replied, as her mother grabbed her purse and headed for the door.
Both siblings hugged and kissed their mother as she said her goodbyes.
Hannah turned to Joe, who was fixing a sandwich in the kitchen. She laughed out loud. "OH MY GOODNESS, Joe! That was the hottest thing I ever saw!"
Joe grinned. "I feel like I never want sex again in my life," he deadpanned as he munched the first bite of his sandwich. "I've seen and experienced hotter things, you know." He grabbed the TV remote and sat down.
Hannah sat next to him and kissed his cheek. "Tell me about them, Big Brother," she teased as she played with his hair.
"Well, watching you with Dad is the hottest thing I've ever seen. I never get tired of it, do you?"
She shook her head, her green eyes twinkling. "No, but what makes it so good is the fact that I'm showing off for the man I love. That would be you. Okay, what's the hottest thing you've experienced?" she giggled.
"I think you know what that is, Baby Sister. Being with you, every single time." He took a big swig of his water.
"Which time was the best?" she insisted.
"Wow, that's a tough one. The easy answer would be the first time, but we didn't know what we were doing and it hurt you," he said, thoughtfully.
"It was so exciting, though!" she said.
"Maybe the first time we did it after we got back home?" he offered. "Remember, it was right after the first time you teased Daddy. Mom and Dad had gone to a movie. Whew! That was the hottest sex EVER!" Joe smiled and felt his cock jerk in his sweatpants. "We took a shower together and washed each other."
"You teased me about Daddy while I blew you," she whispered, feeling the familiar ache in her loins and her nipples begin to harden. "You came so much that I couldn't swallow it all. I don't think I've allowed you to build up a load that big since," she smiled. "I take care of my big brother, don't I?"
Joe took her into his arms and kissed her. She sucked at his lips and tongue, desperate for him to give her what he had just given their mother, a short while ago.
Gasping, she breathed into his ear. "You teased me more about Daddy, and I asked you if you wanted me to fuck him."
Joe could feel his cock beginning to harden. He knew now that he and his lovely sister would soon be having incomparably hot sex again. "You wanted to fuck him. You brought it up to me!" he laughed as he kissed her lips again.
"And you said that you wanted to watch me," Hannah panted as she lay a hand on his crotch and started rubbing through his sweatpants. "Oh, Joe, I need it so bad! Can you? Do I have to wait?"
"I remember exactly how you arched yourself at me while we made love, Hannah," he whispered. "I don't think I've ever seen you so hot for it. The things you said. You were out of your mind. We both were! We were starved for each other."
Hannah smiled, mysteriously. "Remember what happened, afterward?"
"Let me think... I think we showered again and then I tongued your sweet little ass!"
"You violated me by shoving your finger in my ass while taking me from behind! What brother does such a thing to his little sister?" she smiled as she stuck her tongue in his ear.
"And then, while I was fucking you, you admitted to me that you wanted to fuck Dad! What sister says such a thing to her brother when he's doing his best to satisfy her?"
Hannah laughed. "I did do that, didn't I? You know everything I do is for your pleasure. I mean, fucking him is HOT - but I would never have even considered it if not for you."
"I remember that you had a world-shaking orgasm when I kept talking about the possibility!" Joe grinned.
"That's the day you decided to order those cameras, and the rest is history," she stated. "Are you going to fuck me or not?"
"Yes, but can I take a short nap first? I promise it will be better if I do..."
"Sure. I will take a shower and work on some homework. If I get it done, I'll wake you up, okay?"
A half hour later, Joe awoke, refreshed. He realized that his cock was at full mast, which was not unusual when he woke up because he usually needed to pee. He roused himself and noticed that Hannah had the door to her room closed. She was probably making sure she didn't awaken him with her music. How thoughtful. He went to the bathroom, peed, took a shower, donned a pair of boxers, and headed for her room.
He knocked gently and heard her say, 'come in'. He opened the door and saw his sister, clad only in a pair of panties, sitting at her computer. Her feet were on the desk and one hand was between her legs. Then he realized that she was watching porn.
He smiled as he sat on her bed, which was a couple of feet behind where she sat, watching the lurid scene on her computer.
"Little sister is watching BBC again!" Joe laughed. "Don't you dare waste all your cums on this!"
She paused the video and turned to him. "I need to quit watching this stuff. It's addictive, and it makes me want to try that," she said, matter-of-factly.
Joe stood and stepped toward her. He took the mouse and started the video again. Riley Reid, a petite brunette, was kneeling over Mandingo's lengthy cock, taking as much of his thick black shaft into her mouth as possible. Both Joe and Hannah had enjoyed watching several videos of these two, before. Riley seemed to be equally as insatiable as Hannah. There was nothing she wouldn't do, and with great gusto. Mandingo had what they had read was 11 inches of solid black cock. Joe was sure that it wasn't as big as their Dad's black friend, Gary, but it was still really big! Riley, despite her best efforts, couldn't get it all in her mouth.
