<em>"Friends,"</em><br/><br/>That made it all OK. They were just playing around. And if you couldn't play around with your sister, then who could you play with really? Even until the last fraction of a second before she saw fingertips touch cock-tip, Emily was expecting Scarlett to thump her again or slap her cock away from her (that would have hurt but she assumed she had probably deserved it). As it was, as fingertips became palm, and palm became curling fingers around her shaft, Emily let out a long, low, fluttering sigh. At the first pump, she involuntarily pulsed her cock and another dollop of pre-cum plopped from the tip. In an instant it was being spread out by Scarlett's hand as she did another pump.<br/><br/><em>"Ooh, I think you liked that,"</em><br/><br/>"Oh my God that feels so good!" she wasn't lying. That the first person to touch her in that way was her sister was - if anything - better than if it had been a boy. A boy might be interested in Emily just to say he'd 'done it!', Scarlett loved Emily like only a sister could - and not in a creepy way at all thank you very much - so Emily could really enjoy the sensations without worrying about any of the other stuff that might be going through a boy's mind as he did that.<br/><br/>In fact, she was being rather selfish in keeping all those feelings to herself now wasn't she?<br/><br/>"See?!" she exclaimed as she reached over and curled her own fingers around Scarlett's much darker cock. She was being very, very forward - normally Scarlett was the bolshy one, not her - but since they'd agreed to be the other person for each other, then she could hardly back out now then could she ?<br/><br/>She gave three short, sharp pumps on Scarlett's cock. A dollop of pre-cum slid out if it and Emily's hand rubbed it in and spread it out immediately. In another flash she'd taken her hand off her sister's cock, had licked her tongue all across the face of her palm (tasting the remnants of the pre-cum), and then she'd returned her hand to the pumping.<br/><br/>"Mmmmmm. I love tasting myself at this point. I've never tasted my own cum - I always chicken out at the last moment - but pre-cum is nice and slippery and tingly. Well, mine is anyway. Yours......Mmmmmmm, yours is too!" There was another dollop of pre-cum slipping from Scarlett's cock-slit now. It was small, but Emily scooped it up on a finger and popped it into her mouth with added lip-smacking sound effects.<br/><br/>"Have you ever tasted yourself?" she asked her sister. "Cum, I mean. Not pre-cum." What was up with her this afternoon? She was positively lewd with her sister.
