<em>"Wait...what?! You're going to what?" </em><br/><br/>Emily laughed out loud at her sisters exclamation. While she was sure she meant to do it, so often before she'd said that about herself and never followed though. It was a ridiculously naughty thought though, and she could see that Scarlett was struggling to contain herself because of it. Good. Emily slammed her fist down against her sisters balls violently in an attempt to throw her over the edge.<br/><br/><em>"Oh god! I'm...I'm gonna cum!"</em><br/><br/>Oh this was getting to be really good fun now! Emily wasn't stopping what she was doing for a fraction of a second though. If Scarlett really was about to cum, Emily just wanted to make sure that it was a really, really good one. She pumped up and down furiously on her sisters cock hoping and praying that she would send her over the edge before her sisters equal actions on her own cock threw her over.<br/><br/>Scarlett tipped her head back and seemed about to yell something. No words came out though. Emily looked at her for a moment before, like a pipe bursting, her sisters cock started to spurt white goo in a big fountain up into the air and then back down again onto the bedspread. Oh God, she really was cumming. Another pump and another major spurt from Scarlett was enough - with all the jerking that had gone on to this point - for Emily's own barriers to be finally broken and she let out a keening wail "Aieeeeeeeeee!" before she too started to add to the crazy fountains of hot sticky cum. Scarlett was still bucking her hips into Emily's hand, and she was still spurting rope after rope from her cock so that the sight seemed to send Emily into some kind of crazed position that she'd never been in before. Before now she'd maybe shoot two or three moderate bursts from her cock when she came. Now, seeing how Scarlett was, she was spurting burst, after burst, after burst from her cock.<br/><br/>Eventually the spurting stopped.  There were three trails of ropey cum on the carpet in front of Scarlett and two in front of Emily. There was a huge splattering of the stuff on the bedspread in front of Scarlett and a similar sized pool in front of Emily. Emily's hand looked similar to a cinnamon roll did. Except that the frosting this time was her sisters sperm. Could she? Would she? Fuck it! She was going to. Before she chickened out again, Emily uncurled her hand from around her sisters cock and carefully (she didn't want to spill even a single drop) she stuck out her tongue and gobbled up all the gooey cum from her hand. She literally had a mouthful of the stuff in no more than a second and a half. It was then that the taste started to make itself known.<br/><br/>"Mmmmm, yeah... Salty and musky at the same time." she said with her mouth full of the stuff. She knew that speaking with your mouthful was rude and yet she didn't want to swallow it yet. But then if she swallowed it, maybe she could go back and scoop more up? She swallowed it all down and then made a loud, lip smacking, "Ahhhhhhh!"<br/><br/>"More." she told a bemused Scarlett. "Feed me more." She wasn't fussed at this point whether it was hers or more of her sister's. She did know that she wanted more though. In this, as much else, Scarlett was seemingly way ahead of her sister. Emily needed to catch up.
