Holy Crap! Scarlet felt that hot liquid spurt into her mouth and suddenly her entire world was turned upside down...again. Spurt after spurt of cum shot into her mouth, filling it up! She almost coughed once when some got caught in her throat, but she quickly swallowed it and immediately her brain was on fire. She'd tasted her own cum before of course, but this was totally different to that. This cum tasted incredibly different, and the sheer volume going into her mouth as she continued to suck on Emily's cock was intoxicating. Thinking quickly, she began to swallow it as fast as she could, keeping her lips in a vacuum seal around that shaft.<br/><br/>Back and forth, back and forth her head bobbed, so fast she was beginning to get dizzy from the angle. Cum was dribbling from between her lips and down her chin, she just couldn't swallow it fast enough. She could literally feel the amazing liquid coating her entire throat as she swallowed mouthful after mouthful.<br/><br/>The sensation of having her sister cum inside her mouth almost pushed her over the edge. But what really did it? Emily's squealing. It made her whole cock vibrate, and moments later Scarlet was moaning straight into her sister's cock as her own cock erupted with the most intense orgasm she'd ever felt, even today. Every inch of her shaft was on fire with pleasure, and that fire was spreading all over her body. Her own frenzied actions seemed to make it even more intense as she kept bobbing up and down on Emily's shaft.<br/><br/>But the orgasm broke her concentration, and as her cock continued to spray cum into Emily, she accidentally pushed her own head to far forward. A moment later, her eyes bugged out as she felt Emily's cockhead push into her throat. At the same instant she felt Emily's balls against her nose as she gagged around the piece of meat stuck inside her. Pulling off quickly, she realized that despite how uncomfortable it felt, it had turned her on so much! As soon as her mouth was off that gorgeous piece of meat, she let out a wild yell and her orgasm hit it's high point!<br/><br/>Panting for breath, she lay there as her cock stayed rock hard and cum covered her chin.
