Scarlet listened as her sister spoke, unable to respond because of all the raw emotions flowing through her. She was feeling arousal, love, annoyance, guilt, nervousness...all at once! Her heart just kept thudding in her chest as Emily tried to sort her shorts out and try to point out how Scarlet masturbated too. Of course the truth was she did it all the time, but the way Emily said it almost made her mad. Almost as if she were accusing her of something.<br/><br/>Then of course Emily had to go and apologize, and that made her mind spin with even more emotions! Then, for some weird reason, a giggle came out of her mouth. Then another one. And another. Soon she was laughing so hard her entire body was shaking, and she didn't have the slightest idea why!<br/><br/>To be sure, the situation<em>was</em>kinda funny, but she wasn't sure that's why she was laughing. Gasping for air, she nodded and waved her hand, staggering over to the bed. "F-Friends!" she gasped, falling onto it and giving into another fit of laughter. Of course, lying on her back like this with her legs spread, she had no idea she was giving Emily a view right up her skirt.<br/><br/>Finally, she got her laughter under control and wiped her eyes. Sitting up, she looked at Emily with a crazy grin on her face. "Sorry, but do you realize what just happened? That was so classic!" Then her grin got even bigger, and she looked down. "And actually yeah, I jerk off almost every time I'm in the shower. I don't know I just get so horny and I can't stop myself. It's been getting worse and worse lately, and I have to keep running to the bathroom or staying up to relieve the stress."<br/><br/>Leaning back, she patted the bed beside her, motioning for Emily to join her. "Man, you were really getting into it! Look how hard that thing is," she said, pointing at Emily's crotch.
