"I am aren't I?" she giggled the next time Scarlet thrust into her. She gave her sister a wink too. God she felt so fucking full. Katherine was thicker and longer but it was such a tight squeeze. Scarlet seemed to be just right. Could your sister be 'just right' when it came to fucking you? She certainly seemed to be even if such things weren't meant to be thought of in polite conversation.<br/><br/><strong>All</strong>conversation left her brain the instant Katherine pushed her finger in a little bit deeper. Scarlet seemed equally affected, and Emily felt her eyes roll back in her head as she felt the digit wriggling around in there and brushing up against something that seemed almost to pulse when the finger brushed against it. What the hell was that about !?<br/><br/>This went on for a couple more thrusts of Scarlet. Then her sister let go of her boob and Emily wanted to pout because of the loss. There was some shifting, some loss of rhythm for a thrust or two and then Emily looked down because now she was getting even<strong>more</strong>sensation when she though that that would be impossible. What the ?<br/><br/><em>"MMm, like that sis? I think I'll have to-OH FUCK!"</em><br/><br/>Oh Fuck indeed. Of course she'd never had a tit-fuck. Two hours ago she'd never had an anything-fuck (your own hand didn't count). She was being stimulated in three places all at once. Her ass - by her mother - and her pussy and cock by her sister. She couldn't even always find the mental capacity to wail such was her arousal. The second finger inside her ass was just the last straw. She felt her brain might actually be crashing. Could brains crash?<br/><br/><em>"Go faster Mom! Please go faster and deeper!"</em>Scarlet wailed. Faster!... Deeper? Emily felt like her entire body might suddenly explode into a cloud of wet cum. She wanted some time to get used to this. If it were just one thing she could cope. Two even maybe. Three and she was losing it. Really, really losing it.<br/><br/><em>"Oh fuck...cum with me Emily! I'm gonna cum soon, and I want you to cum with me!"</em><br/><br/>That was the straw that broke the camel's back. Scarlet was going to cum. With a quickly nodded "Mmmhmm!" she felt herself try and break her mother's fingers and her sister's cock. She clamped down on both as hard as she physically could. There was a white heat building up inside her; in three places all at once. She tried to hold it back, she tried to keep some semblance of reality about her. Exploding into a cloud of wet cum was going to be so fucking embarrassing.<br/><br/>Too late!<br/><br/>"Mmmmmmmmmmmmmcumming!" she wailed. She came in three places at once. Her cock exploded all over Scarlet's front and her own. She felt a gush of herself splash into her chin. Another gush exploded out of her pussy. She didn't even know pussy's gushed. Well, of course, they were were you peed and all that but she was pretty bloody sure that she hadn't just peed all over her sister. Had she? One quick look at Katherine's wide-eyed marvel persuaded her that she had not. If you peed on your sister your mother didn't look at you like that.<br/><br/>"You're a squirter Emily!" Katherine chipped in happily still pressing her fingers against whatever the hell that was in her bottom. 'Whatever the hell it was' seemed to be tied intimately to her cumming because she immediately felt another massive squirt out of her pussy as one more bout of cum jumped from her cock.<br/><br/>"MmmmmmmmmnnnnnnnSorrry!!!!!" she wailed. She was obviously broken. Her sister and her mother weren't doing any of this - her first night of sex and she'd been broken. How totally fucking unfair!<br/>
