They really were quite sexy nipples. Emily was quite proud of them: deep mocha - maybe even as dark as Scarlett's general skin tone - and surrounded by a cinnamon areola. Yep, sexy was the word for them. She got that right.<br/><br/>Scarlett tried again with a very much more gentle squeeze. "Yeah, mmmmmuch better." Oh she was in quite the naughty mood this afternoon. Hence the question about boys and their bits and bobs.<br/><br/><em>"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.... Come on, lets get these shirts off. I want to see those tits!" </em><br/><br/>It seemed like it wasn't only Emily who was in a naughty mood. No sooner had Scarlett suggested it, both tops were off and in the middle of the floor.<br/><br/><em>"Perky...very fuckable."</em>Emily burst out laughing at that and thumped Scarlett in the arm once more.<br/>"You can't say that to people, sheesh Scarlett, you really were left at the bottom of the garden in a basket weren't you?<br/><br/>If the 'fuckable' remark got that response, then the response from when Scarlett leaned down, slipped the nipple into her mouth and sucked on it was something of a disappointment - from one perspective anyway.<br/>Emily couldn't shout at her sister for what she was doing because she was groaning too much.<br/><br/>"Whaaaaaa.....Mmmmmmmmmmm" It was nowhere near being a word. Right at that moment she didn't know any words. Not a one.<br/><br/><em>"Feel good sis? I've always wondered what it would feel like to have my tits sucked...or suck someone elses."</em><br/><br/>Yeah, that was Scarlett. There really was no filter between brain and mouth. "So now you know. And just so we are both on the same page, it felt freaking awesome." The second one felt freaking awesome too. Scarlett had taken to heart the plea to be gentle and she really was being. Firm, but gentle at the same time. Emily found her eyes were rolling back in her head as Scarlett sucked and licked. Eventually she let go with another pop.<br/><br/><em>"Just imagine, if my mouth feels this good on your tits think of how good it would feel on that little cock of yours," </em><br/><br/>"I don't have a little cock." she said immediately. It took a second or two before she realized what her sister had said though - she was always being rude to her when they were alone (even though they loved each other loads) and so the insult met with a riposte without even the slightest delay. It was only when Emily's brain caught up with what she'd suggested - and the tone she'd used to suggest it - that she really realized what she'd said.<br/><br/>"Are you? You are, aren't you ?"<br/><br/>She was serious. She even licked her damn lips.<br/><br/>"OK, but I'm not having you do it to me and then not letting me do it to you or something. Or running around telling everyone you 'did' me or something without me being able to say the same thing. If we are going to do this, then we are going to do it together. OK?"<br/><br/>There was absolutely no disguising the fact that the thought of someone sucking on her cock was perhaps the most erotic thing Emily had ever heard. It didn't even enter her head that it would be Scarlett. They were just messing around, it didn't mean anything other than they'd potentially found another thing to do together. They were growing up, after all, and playing catch or chasing after each other only had limited appeal nowadays. Mind you chasing after each other and then sucking each other off..... That might be a twist they could add in ?<br/><br/>That was for another time. Scarlett was still deadly serious. She was still licking her lips, and Emily's nipples were still a bit tingly from where she'd been sucking. If they felt good, what on earth would her cock feel like. Yeah, they should deffo do it.<br/><br/>"Lean back down on your side." she told her sister. She did, and at the same time she unhooked the skirt and threw it on the pile on the floor. That was a good idea, they didn't need stuff getting in the way of the view now did they? Emily sat up and whipped the shorts off. Now they were both completely naked (aside from Emily's socks). She laid down on her side the exact opposite of Scarlett. She was around about knee level, and so she wriggled and scooted until she was much better positioned. Scarlett's very dark red cock-head looked enormous from about two inches from the end of her nose. She wasn't going to go and tell her that though. She'd never hear the end of it.<br/><br/>Closing her eyes and opening her mouth - and then opening her eyes again since there was no freaking way she was not going to watch this all the way from start to finish - Emily stretched her neck and laid her tongue on her lower lip and moved forward until she felt it touch something wet and slippery. She flicked, and the wet and slippery thing burped a dollop of half-cum-half-precum onto her tongue. She gobbled it down and was done with the pussy-footing around stuff now. She made a big 'O' with her mouth, bobbed forward even more, and started to curl her tongue around Scarlett's cock-head. She started to suck it firmly - but gently - on her sister. More than anything right now she wanted to feel her mouth filling with cum direct from her sisters shooting cock. Fuck! Her own tensed just as Scarlett enveloped it. My God!!!!
