Chapter 137 Heading Home

As they walked out of the theater and headed to the parking lot, he said to his sister, "You know, we're not actually going to do anything more tonight, are we? For one thing, I don't think my dick could take it. Not to mention my heart."

"Whatever you like, sweetheart," she said breezily, still happily clinging to him. "I just love to get off, and get you off. Now that I've started, I don't think I'm ever going to stop. Isn't it great that our bedrooms are only ten feet from each other? Any time your big boner gets even the slightest twitch of life, just come on over to my room and I'll suck you dry, okay? Now I know why God gave me this pair of lips. Not to eat food; who cares about that? No, it's so I can be an insatiable cocksucking machine for my big brother. Anytime and anywhere he wants it."

"Katherine!" he complained. "Not here!" Although they were outside, there were some other people nearby walking to their cars.

However, there weren't that many since it had been such a late movie, and Katherine was still so horny that the idea of strangers watching only encouraged her. "Why? Does that get you excited? It does me!" She grabbed at his penis through his pants, but it was down for the time being.

"Katherine, what's gotten into you?"

She let go and put her hands behind her back. She tried to look innocent and even skipped a bit as they reached the sidewalk outside the theater. "Oh, I don't know. Maybe that I love my brother, and he loves me?"

She turned to him and flashed him such a winning smile that he thought his heart would melt. His fears and doubts dissolved completely, and they walked down the street in a state of near giddiness, hand in hand.

"I don't know who this brother of yours is," he finally said, "since you wouldn't want to be mentioning that kind of thing in public. But I have a sneaking suspicion he loves you very much too."

"I know," she said confidently. "I just have one request."

"What's that?"

"That you don't see any more movies with Christine."

"Okay, fine. After what you just did to me, I'd give you the world. However, you should have been more demanding. No more movies with her, but that doesn't mean no more outings period."

"Grrr!"

"But why? Why this big jealousy of her, and only her?"

"You doofus! Don't you get it? It's because she's like me, but better. Mom and Aunt Suzy are different enough that they don't feel like direct competition. But Christine feels like competition."

"Never. First off, there's nothing going on with her and me, so don't worry. Second, I love you so much that it physically hurts. True, I had a crush on her, but that doesn't even begin to compare with the years of fun and love you and I have shared. And most importantly, she's not better than you in any way, unless maybe one is into breast size, and I don't know anyone like that."

She laughed at his joke since he was such a notorious tit man. She elbowed him in the ribs. "Liar! However, I love that you lied for me." She clung to him even tighter.

The truth was that he was lying. Christine was not only drop-dead gorgeous, but she was also a near genius. That was what Katherine feared the most, because she knew that Alan's interest in a beautiful airhead would only go so far, but Christine had the smarts to be a potential soulmate for him. However, he was honest in expressing how much stronger his feelings for his sister were.

Changing the subject, he said, "By the way, one more thing I forgot to mention. Guess what I found in my pocket last night?"

"Let me see." She reached over and grabbed his penis through his pants again, not even getting close to a pocket. It happened to be flaccid though. It deserved a rest.

"Not that!" he said, "Or, not just that," he chuckled. He pulled out a key. "I found the key to the supply closet. I didn't mean to, but in all the excitement I forgot to return it to Ms. Rhymer on Friday."

Katherine's eyes lit up. "Interesting! Since you told me, then I guess you'll have no objection if I make a copy before school on Monday. Hee-hee!"

They made it to the car. It was a dark parking lot and they were far from anyone else. As Alan stood by the car, ready to open her door, Katherine said, "Here, let me get your keys for you."

Alan rolled his eyes and sighed. "Sis, first off, I can get the keys myself. Secondly, that's not even my pocket."

She feigned confusion. "It isn't?" She giggled. "Never mind though. I've found something a lot more interesting." She rubbed Alan's newly emergent erection through his pants.

Alan put his hand on her wrist and tried to pull her away. "Sis, please, don't. I don't even know how it got hard yet again, but if I cum one more time, I think it's going to break or something. I'm serious."

She stopped stroking it for a moment, but then said, "Awww. Poor thing. Looks like it could use some help. Oh! I know! How 'bout I give it a good massage?" She broke into another fit of giggles as she resumed stroking it.

Alan was still trying to pull her hand away, but not trying that hard. It simply felt too good. At least he managed to grasp her wrist tightly enough to keep her hand from moving up and down very much.

He thought, Sis has already tried something like this twice since we left the movie theater and she just won't take no for an answer. Doesn't she realize the danger, even out here in the parking lot?

His thoughts ran deeper. You know, Sis has always been a bit spoiled. Why is it that she got that way and I didn't? I think maybe it was because Mom seemed to need my help with Ron being gone so much. I remember one time she told me that with him being always overseas, it was up to me to be the "man of the house." That made me feel so good, so responsible.

Hmmm. I wonder if, even back then, I was so eager to be a good kid just so I could win Mom's favor in hopes of becoming her lover someday. I mean, I tried so hard not to look at her as a sexual creature, but when your Mom has looks to put most Hollywood actresses to shame, it's hard not to feel something, at least subconsciously. Not to mention her chest. DANG, that chest!

Alan luxuriated in intensely pleasurable feelings as he thought about his mother and her big rack. He realized that his feelings seemed uncommonly powerful, but then he remembered with a start that his sister was still stroking his erection. While he was thinking, he'd relaxed his arm, and now his hand was moving up and down too as Katherine's hand carried it along.

He grasped her wrist tighter and pulled her hand completely away from his crotch.

"Awww..." she pouted. "I was using that. Can't you play with one of your own?" She giggled.

He finally took the car keys out of his pocket. "Sis, come on. I told you no, and I'm serious. You have to promise me, no fondling like that in public without my permission. It's too dangerous and you could ruin everything!"

With a pouty sigh, she conceded. "Okay. God, that's fun though. I could feel the warmth right through your pants."

They finally got in the car and headed home.
