Chapter 01 - Bitches
Tommy was sitting at his desk pondering the changes that had occurred in his mother and sister's moods over the last few months. His father had run off with a woman from his work about ten months earlier. Mom, Cindy, had turned into a real bitch right afterward but about a month later she reverted to her normal jovial self. Two months after that his sister, Marla, who was now nineteen, had moved out to live with her boyfriend. Almost immediately, mom was back to her highness, Ms. Bitch, again. This time it went on for four months. Then Marla moved back home after breaking up with her boyfriend and she had been a bitch since her return. Mom's mood went back to normal almost immediately after Marla came back. This continued until a couple of days after Tommy's eighteenth birthday and mom's bitch persona returned. Tommy was nearing the end of his rope living with the two bitchiest people in the world.
After looking at the timing, Tommy began exploring possible causes. His dad, Lee, leaving may have been what started it all for mom but the irregularity seemed to be more associated with Marla's presence or absence than anything. Yet, even that had it's inconsistencies. In Marla's case it did coincide pretty well with her boyfriend not being there. Tommy examined the changes in himself and saw very little. Until he had gotten the laptop, mom had been good. He was spending a little more time in his room since then but otherwise he couldn't really remember any other changes. Maybe they were both depressed or something. He fell asleep still not having found the answer.
Tommy was watching TV on Saturday morning when Marla sat next to him on the couch.
"Tommy?"
"Yeah, sis?"
"I'm doing a study and I need your help."
"What kind of study?"
"Analyzing semen."
"Why do you need my help?"
Marla handed him a small plastic cup with a screw on lid from the doctor's office.
"I need you to collect a sample for me."
Tommy looked at her, blushing.
"You want me to jerk off in a cup?"
"I need your specimen so I can test it."
"What are you testing it for?"
"Hormones, I suspect. Would you do it for me?"
"Sis, this is weird. Why me?"
"Because you're a guy. Semen only comes from guys."
"I knew that, but why me specifically?"
"I was getting the semen from my boyfriend before but he's not in the picture now."
"Do I have to do it right now? I'm watching a movie."
"No, how about around bedtime?"
"I'll try. This is strange, Marla."
"I know it seems strange but it's for a good cause."
"Okay. Since we seem to be having a good moment can I ask you about something?"
"Sure."
"For about a month after dad left mom was a real bitch. Then she was fine until you moved out when she turned into a bitch again. You came back and she was fine again for a while but since your return you've been really hard to live with. Mom was fine until my birthday then she turned bitch again. Any clue what's going on?"
"Men, hormones, sex or lack of it, maybe. Who knows?"
"Marla, it's getting so bad around here I wish I could leave. Today's the first time you and I have had a civil conversation since you've been home."
"I'm hoping that's going to change very soon."
"Yeah, you and me both."
"Will you get the specimen for me?"
"Later this evening."
"Just set it on my bathroom counter when you get it."
"You don't want to refrigerate it?"
"No, it needs to be fresh and still warm."
"Okay."
"Thanks, Tommy." Marla stood and left the room.
For the rest of the day both Marla and mom were their normal bitchy selves. Not just to him but to each other too. Tommy tried to avoid them both as much as possible. That evening he watched some porn on his laptop, collected the specimen for Marla and set the cup on her bathroom counter. He was glad he didn't have to hand it to her personally. At least this way it wasn't quite so embarrassing.
Sunday was their traditional day to clean up the house. One of Tommy's chores was to go around the house and collect the trash from all the trash cans. When he picked up the bag in Marla's bathroom trash can he saw the empty cup. That ticked him off a bit. He had collected the specimen for her and she had dumped it and thrown the cup away. After dinner that evening Marla came to him with another cup.
"Tommy, can you get me another specimen tonight?"
"What the hell, Sis? You threw the one away I gave you yesterday. I found the cup in the trash can this morning."
"I tested it first. The whole specimen was used. All you found in the trash was the empty cup. Please?"
"How often are you going to want these?"
"Every day if you can."
"You really did test it?"
"I really did. Will you get one for me every day?"
"On one condition."
"What condition?" she asked hesitantly.
"That you try to be less bitchy to me."
Marla was relieved. She was afraid he was going to ask her to start collecting them herself.
"I'll do my best."
"Okay, I'll do it."
Every day for the next couple of weeks he collected her specimen. She had given him a whole case of cups and lids which he kept in his room. He did notice that her bitchiness had pretty well gone after about a week. It wasn't just toward him but she was back to normal in her dealings with their mom too. One evening after collecting her specimen and dropping it off he went back to his computer and watched some more porn then jacked off again. When he came, he collected the semen into another cup out of habit. He capped the cup and walked into her bathroom. Marla was standing there with the earlier cup open and licking out the last of the contents. Tommy froze where he was, watching in disbelief. When Marla had gotten the last of it she noticed him standing there with his mouth agape. She blushed but didn't speak.
"What the fuck?" he asked.
Marla tossed the cup into the trash.
"I guess we should talk, huh?"
"I guess."
They walked into her bedroom and Tommy sat at her desk. Marla pulled up a second chair and sat by him.
"Tommy, the testing was for me. At work we treat people with sexual problems sometimes. Several weeks ago we saw a lady that had turned into such a bitch over the last several months that her family insisted she get checked out. After a lot of testing, the doctor diagnosed her as a cum addict. If she doesn't get her daily dose of cum, she's a bitch. It made me wonder. When Mike and I were together I was fine. After we split up was when I became a bitch. I decided I would see if what the doctor suggested for her would work for me. I am a lot less bitchy than before."
"Yeah, you're back to normal for about the last week."
"I've been drinking your cum every time you brought one. I feel better in every way. I'm even able to cum again now when I masturbate."
Marla stood and walked to the bathroom then returned with the fresh cup he had delivered. She opened the cup and poured it into her mouth. Marla swished it around and showed it to Tommy before swallowing it. Tommy got hard the minute the first drop had landed on her tongue.
"Damn," was all he could say. He sat there with his mouth open.
"Will that help to motivate you to get me more?"
"Oh, yeah. I enjoyed watching that."
"If it helps you to collect my specimen, you can watch me take it every time."
"Deal, how much do you need a day?"
"One has been working beautifully. The second one today was dessert."
"Marla, do you think that's why mom's been such a bitch?"
"Mom got bitchy after I moved out right?"
"Yeah."
"Since it's about cum, let's look at that. Did your jacking off change when I left?"
Tommy thought for a moment. "Not the frequency but where the cum went did."
"How did that change?"
"When you were here I jacked off in either your bra or panties."
"Where'd you cum after I left?"
"Into a tissue and flushed it."
"That's when mom got bitchy again?"
"Yeah."
"When I came back did you start using my undies again?"
"Yes, until I got my computer. Then I started watching porn and using a tissue again."
