Your Sister's Pissed

You go back into your house while your mom stays outside to sunbathe. You head right up to your room, sit down, and collect your thoughts. In a 24 hour span you fucked the hottest girl in school, you fucked your sister, and got blown by your mom in front of your neighbor. You needed some time away to clear your mind.

You kill a few hours playing a video game on your PC. The entire time you have your headphones on and can't hear anything around you. Once it hits about 8pm you decide you have to take a whiz. As you remove your headphones you can hear arguing downstairs.

You head down to the kitchen to find your mom and sister going at it. As soon as your sister sees you enter the room, she comes up and gets right in your face. "You little prick, you got me fired from my job!" You had no clue what she was talking about. Your mom jumped in to defend you. "Your little brother did no such thing. You need to separate what happens in this house from what happens out in the world. There will be other modeling jobs Andrea." You turn to your sister and ask what happened.

"Well you giant dick, when I went to work they said I wasn't bringing enough intensity and they fired me!" You just shook your head. "Um, what does that have to do with me sis?" Your sis lifts up her fist as if to punch you, but holds back. "Maybe it's because I didn't feel sexy on a count of that I had to fuck my little brother right before I went to work. It's not exactly easy to be seductive with your brother's jizz oozing down your leg." You can't help but laugh a little though you feel bad. You started to tell Andrea that you wouldn't use her anymore; that you could find someone else. Your mom interjects before you have the chance to say anything.

"Andrea, we talked about this. Yes, there would be some sacrifices living with a man who has to cum as much as John does. But I told you over and over that it was just mechanical. There were no feelings involved. Hell, I just blew John in front of Mrs. Dunkin. You don't see me getting all upset. You have to learn to live your life knowing that your brother is occasionally going to use your body to achieve orgasm. Do you want him not to cum?"

Andrea had tears in her eyes as she shook her head. "No mom, I want him to cum. I understand that it's not his fault." Your mom walks over to Andrea and gives her a hug. "Listen honey, I know it's an adjustment. I think with some immersion therapy you be able to learn to live with your brother's cumming." Your mom then places a hand on your shoulder and the other on your sisters. "How about this. John, can you spend an entire day using your sister to cum?" You gleefully nod. "Okay then. Andrea, tomorrow you are going to be John's cum buddy. I think an entire day of experiencing your brother will de-sensitize you." Andrea nods in approval.

As you both head upstairs to get ready for bed. Your mom has a command. "John, I want you to sleep in Andrea's bed tonight. Is that okay honey?" You nod in approval. Andrea starts protesting. "Mom, I don't want him in my bed! That's gross!" Your mom places her hand back on Andrea's shoulder. "Honey, trust me. After 24 hours of your brother non-stop, having sex with him will be like helping him with his homework. It won't mean anything to you."
