The next day was fine and warm, and Danny and I went down to the swimming hole again; only we were both too chicken to get in the water. We just sat in the sun and talked desultorily about this and that. Neither of us mentioned yesterday with Mel, or us jacking off together. And I wasn't about to say anything about the later episode in her room either! The next thing we knew, Her Ladyship herself appeared, shucked off her track pants and top without a word of greeting, and dived cleanly into the icy pool.
And, just like the day before, when she got out, her nipples stuck out like big pencil erasers. She stood over us with her feet planted apart, towelling herself off. Both Danny and I took sneaky peeps up the smooth columns of her taut legs in an attempt to see her crotch, but neither of us trusted ourselves to look at her directly. It was fascinating the way the water dripped to the grass from the gusset of her swimsuit as the fabric drained itself of moisture.
"So, aren't you fine gentlemen going to warm my nipples up for me today?"
We shot startled looks towards Mel's face to see if she was serious. But neither of us got that far, because my sister had slipped the top half of her bathing costume right down, exposing her hard-tipped breasts to the open air.
I gasped with the force of my sudden erection. "Oh c-c-cripes, Mel!" I stuttered. "Come down here!"
She dropped her towel between us, and Danny and I stretched it out flat for her. With a wondrous gracefulness, Mel joined us and stretched out on her back. Then she reached out, placed her hands on the backs of our necks, and guided our mouths to where she wanted them to go.
"Ooooh yessss!" she sighed as our warmth enclosed her hard points. "That is soooo wonderful!"
Danny and I suckled on Mel's nipples for ten minutes and more. She gasped and sighed and thrust he chest up to us in turn to take even more of her breasts into our mouths. She stroked the backs of our necks and ruffled our hair. I tensed at first when she did that, but then realised that there would be no banging our heads together today.
It took me a while to recognise, from the writhing movements of Mel's lower body, that Danny was doing more than just sucking on her tit. I took a quick look over at him and saw that he had one hand stroking her skin just above her navel and was trying to push her bathing costume down further. It seemed to me that my friend needed some help in this worthy endeavour, and my hand joined his straight away. Mel's warmth and smooth softness flowed through my fingertips, reminding me that this was the first time I had ever touched her so boldly!
Mel let Danny and I stroke her and push the stiff fabric down past her waist to her hips, but then interrupted us, saying, "No please…don't…you mustn't!"
