<em>"Owwwww!"</em><br/><br/>Scarlet felt her sister jerk back, and she realized she might have pinched a little hard. Blushing, she glanced down at the two cocks, and Emily's next words confirmed her thoughts.<br/><br/><em>"Be gentle sis.... It feels nice but not too hard OK?"</em><br/><br/>"Sorry," she muttered, but she couldn't keep the smile from tugging at the corners of her mouth. "They're just really sexy nipples."<br/><br/><em>"You want to play more with my boobs? Then be gentle with them, OK."</em><br/><br/>"OK," she giggled, giving her sister's nipple a VERY gentle squeeze. "Better?"<br/><br/><em>"Have you done this with boys yet? I mean, played with their bits and bobs and stuff. I haven't yet." </em><br/><br/>Scarlet shook her head, blushing a little more as her hand softly caressed Emily's tit. "No...not really. One time I ground my ass against a boy's crotch, but I didn't know him at all. We were just dancing. I've kissed Jake a couple times, you know the quarterback, but you know he gets that all the time. And he's not nearly a good kisser as you," she finished with a giggle.<br/><br/>"Come on, lets get these shirts off. I want to see those tits!" Reaching down, she grabbed Emily's shirt and pulled it up over her head. "And now mine..." and she pulled her sports bra up over her head, letting her own teen tits spring free.<br/><br/>It wasn't the first time she'd seen her sister's tits. After all, they changed in front of each other all the time. But this was the first time she got a good, up close look at them, and the sight sent her heart thudding rapidly. "Damn, these are nice," she murmured, giving them both a soft squeeze. "Perky...very fuckable," she added, giving Emily a sly wink.<br/><br/>Then Scarlet did something that was bold even for her. Leaning down, she wrapped her lips around Emily's nipple and began suckling like a hungry baby. Her tongue swirled in circles around the erect nipple, and her lips sucked on it tightly. "Mmmmm," she moaned, and she meant it. The soft flesh felt incredible under her lips, and Emily's nipple was so stiff and sexy. Shit, she even tasted great!<br/><br/>Letting go of Emily's breast with a small *Pop!* she gave her a big grin. "Feel good sis? I've always wondered what it would feel like to have my tits suck...or suck someone elses." She then moved over to the other nipple, suckling on that one more gently and slowly, really taking her time to lather her sister's areola up with her tongue. The tip of her long tongue flicked over her sisters nipple, and she gave a couple of hot breaths onto it.<br/><br/>"Just imagine, if my mouth feels this good on your tits think of how good it would feel on that little cock of yours," she purred in a sultry voice.<br/>
