4th Meal

You wake up in the middle of the night. Your hand is still groping your sister's breast, and your cock is rested perfectly between her butt cheeks. You realize that you have to piss. You start getting out of bed to do just that, then decide that you need some "help". "Hey, sis, wake up" you whispered as you shook her. "What do you want? I'm sleeping" she responded, barely awake.

"I need to piss" you whisper in her ear. "Okay, then piss, you don't need my fucking permission" she says before putting her head back down on her pillow. "No sis, I need your help. You need to come with me into the bathroom." Andrea starts saying something but catches herself. No doubt she was going to tell you off then thought about how mad it would make mom.

You both walk into the bathroom and turn on the lights. As you each stand there, completely nude and half awake, you lift up the toilet seat. "Sis, I need to piss but I can't lift my dick. Can you help me?" Andrea gets a look in her eyes that you think will burn through you. She takes your cock, picks it up, and aims it in the toilet bowl. You begin to urinate.

You start giggling at the idea that your sister is helping you piss. She looks like she's never had less fun doing anything. Once you finish, you ask her flush the toilet as you wipe the last drop of piss off on Andrea's leg. As soon as she's done she announces that she's going back to bed. You grab her arm though and spin her around.

"Sis, I can't sleep. Make me some food." Again, she looks like she wants to kill you, but she complies. You both walk downstairs and into the kitchen. She opens up the fridge and starts naming off what she sees. You stop her and tell her there is only one thing you want. "I want that cake you brought back Friday night." Andrea went on a date and brought home a slice of turtle pie. She had warned you yesterday not to touch it.

"John, seriously, the fridge is full of food. Do you have to eat that?" You nod and smile from ear to ear. "Sometimes Andrea, after I have cake I have an easier time cumming." Andrea brought you the box with the slice of cake. "Sis, this isn't classy. Put it on a plate and bring me a fork with it. Oh, some milk too please." Holding back all the rage she can, Andrea does as you ask. You find yourself with a nice midnight snack in front of you.

As you finish your first bite, you make another demand of Andrea. "Sis, this cake is so good that I need to cum. Get under the table and blow me." Andrea is clearly defeated now. She goes under the table with no objections, takes your dick into her mouth, and begins giving you a blowjob. The taste of the cake coupled with your sister's blowjob really is an amazing combo.

To further antagonize your sister you make frequent comments about how good the cake tastes. Right as you finish the last bite you send a wave of cum down your sister's throat. Once you're done, you ask her to clean up and meet you back in bed. You fall asleep right after she climbs back under the covers.
