Stevie comes back

As Emily is showering her eyes fall on her lower belly. It has been 5 days now since Stevie put her sperm inside there. 5 days in which she could be pregnant, but she doesn’t know. Well, she can’t be, right? Women don’t get preggers because of one single batch of sperm. If they did, all of her friends would be pregnant already and they aren’t. No, the only reason Emily masturbated last night is because she needed a booty call, not because the curse was taking effect.

A few hours later Stevie returned home.
“Stevie, you’re back.” Emily says happily.
She runs up to her brother and gives him a big hug. She’s never been so happy to see him before. What is this feeling?
“How have you been?” Emily asks.
“Oh, you know. We went on a date, then to her place, she gave me a blowjob. The usual.” Stevie explained.
When Stevie brought up the blowjob he got from his girlfriend, Emily imagines herself in his girlfriend’s place and thinks, “I can do that better than her.”

Emily’s hands then go for her brother’s groin and she starts feeling up his junk.
“Something wrong, Emily?” Stevie wonders.
“I’m just curious.” Emily asks. “Who is better at giving blowjobs. Your girlfriend or me?”
Stevie smiles and says, “Not sure. I may need another one from you to tell for certain.”
You smile at your brother but get on your knees for him anyways. Then you start unbuttoning his pants and take out his dick. As soon as Stevie’s dick is free from the confines of his pants is it trapped inside the confines of your mouth. You bob your head and use your tongue like he explained you last time. In your attempt to be better than his girlfriend you even push your head all the way to his groin. This causes Stevie’s cockhead to push into your throat, but you are fine with that. If it takes you deepthroating him to convince him you’re a better cocksucker than her, so be it.

This time when Stevie came, she didn’t pull away. She kept his dick in her mouth and enjoyed his warm cum splashing onto her tongue. After Stevie is finished Emily pulls her mouth from his dick, careful not to spill any of his sperm. She then looks up and opens her mouth, showing his sperm collected on her tongue. She closes her mouth and swallows. Then she opens her mouth again, showing Stevie her tongue, now with no sperm on it whatsoever.
“Yeah, you are the better cocksucker, sister.” Stevie admits.

The rest of the day went pretty much as usual. Except, Emily kept feeling like wanting to be closer to Stevie. Whenever she and her were in the same room, she felt fine. But when they were in separate rooms, she felt a little uneasy. This didn’t change at night, when each of them was in their own bedroom. While trying her best to sleep her thoughts keep going to her brother. His nude form, his erect dick, his dick inside her, she enjoying his dick …

Eventually Emily can’t take it anymore, she got too much pent-up frustration. She needs to do something about it, but what?
