Well, it's kind of hard to refuse, isn't it?

In your head, you know that it would be better not to let Lime take up the task of washing your body for you. Considering the fact that she finds your sweat, saliva and...other fluids irresistible, it seems like tempting fate to let her have full reign over every inch of your body. It would be like waving a child's favorite candy right in front of their face and expecting them not to reach out and grab it. You knew, intellectually, that you should be taking the cloth from her and washing yourself so that you'll be ready to leave and get to class and not be late.

But, with Lime's large, soft breasts pressing into your back and her hand caressing your chest, it is difficult to think with your head. It is far easier to think with a part of your body that had been long neglected in your studious eighteen years of life. A part of your body that, feeling Lime shift against you and rubbing slightly stiff nipples against your back as she continues to rub the cloth along your skin, has well and truly sprung to life as your manhood now juts forward in its full erect state. You feel it throb with arousal and can't help but blush deeply at that uncontrolled reaction in you, your hands moving down to try and cover your prodigious length up though it is impossible to do so really.

You try and find it in you to resist Lime, but, instead, you sigh and nod. "Fine, okay. If you want to wash me, you can go ahead. Just...let's try and keep it just washing, okay?", you tell her with a pleading look in your eyes.

She smiles brightly at you, but that gives you no indication if she understood your words...or, if she had, if she would do as you asked. Though she did seem to understand you had given her permission to continue and you can't help but feel pleasure as she rubs the wet cloth over your skin...though she only does this for a few moments before she drops the cloth and is instead rubbing you with her bare, slick hand.

"Hey, c'mon, that's...", you start to say, but you notice that she is not leaving behind slime, but instead only water when she touches you. Perhaps it was when she had dipped her hand into the basin that she had absorbed the water into herself? It stood to reason, you supposed, that she could control the viscosity of her body and whether she left any of herself behind or not. You really couldn't say as your book hadn't given you much information about such things. You'd probably have to get a book that focused on slimes to find your answer, you suppose.

While you are thinking about this, you see Lime stretch (quite literally as her arm lengthens to allow her to reach) down to place her hand into the basin. She let her hand linger there and, as it does, the water level seems to lower as her arm seems to become more plump as what you can only assume is water moves up through it. She seems to be absorbing the water into her form and you wonder where it is all going...until you feel the weight of her already hefty breasts grow larger and more prominent on your back. The press of her breasts becomes greater and you shiver in delight as you feel her start to move against your back, stroking her breasts up and down along your skin. Again, you feel wetness left behind that is sans that gooey quality that Lime had left behind when touching you before. She is washing you with her breasts, it seems, and you can't complain at all about it.

She seems to enjoy it as well as her nipples become firmer and you hear her make soft pleasured noises as she rubs her bosom against you, up and down your back until she is down low to press them against your firm rear. You jump a bit at that, but she doesn't let you go too far as you feel her arms wind about your middle and start to rub her hands along your stomach and sides to wash you there. As she does that, her breasts press against the backs of your legs and, shockingly, you feel her lips and tongue sliding against your buttocks.

"H-hey! Lime, what are you d-doing there?", you ask, embarrassment hot in your voice and on your face as she licks against the skin of your taut bottom again and again, "Y-you don't have to do that! Come on!"

Your embarrassment and, much to your further chagrin, your arousal spike higher as you feel her tongue, that lengthy and agile tendril of slime, slip between the cleft of your buttocks and the tip of it tease at a part of you that had never been touched by anybody in such a way before. She prods her tongue against your tight, puckered anus and you nearly jump again as you realize what she must be intending.

"No! Lime, I know what you're thinking, but don't you do it! You hear me?", you tell her, your voice frantic as you try to get the slime girl to abandon her current, more than embarrassing and dirty plan of action.
