Our little plan worked. Soya Milk and Cornflakes hid sperm and vaginal juice stains perfectly. Of course, it earned both of us a good telling off and some extra chores to do after school that evening, but it got me out of a pretty pickle. It also meant no swimming as well and thus, very little opportunity to talk.
Rain interfered with swimming again the next day. The day after, Mel bailed me up behind the school caretaker's shed at lunchtime. "Make sure that Danny comes to the swimming hole after school!" she told me.
Alarm bells started ringing in my brain. Something had got into my sister. She had become a totally different person; one with a dangerous streak, and I was becoming a bit scared of her. In the belief that Mel wanted to be alone with Danny, I protested, "You can ask him yourself, can't you? Why should I do your dirty work for you?"
"Thank you, brother! After I saved your butt the other morning!" She glanced quickly around to make sure that nobody was looking, then quickly undid my pants and slipped her hand inside. "Ok, our butts… C'mon Joel," she wheedled, "you're ahead of Danny now. He's your friend isn't he? Don't you want him to catch up just a little bit?"
"You want me there as well?" I stammered.
"Of course, silly! You've got a lot to show him. Not everything we did the other night though…no, not yet. We can't go spoiling him by showing him everything at once, can we?"
My heart lurched in my chest. I felt sick with apprehension, but wildly excited as well. "Oh, Ok then!" I gasped.
Mel squeezed my rock hard erection. "Come here," she breathed. Her eyes had a wicked gleam to them. She pulled me closer to her, lifting up the front of her school dress with her other hand. Quickly pulling my dick out of my underpants, she pushed it into the gap at the top of her thighs and closed them tight around it. She had her panties on, of course, but it still felt amazing. She nestled her forehead into the crook of my neck, murmuring, "I can't wait to do it again like this, like we did the other night. I think about it all the time."
"Me too, " I mumbled, experimentally rubbing my shaft against her.
"Ooooh! That's lovely!" Mel whispered, "I wish I could feel you properly…here!" She slipped her hand under her skirt and pulled the gusset of her panties to one side. My dick slid easily in her slippery wetness. "Aaaaaaaaah!" she sighed deeply, "So nice!"
Just then, the bell sounded, summoning all the kids back to their classes. Mel and I hurriedly tidied our clothing and took off in different directions so that we would arrive at the school entrance separately.
We were waiting at the swimming hole when Danny arrived. The weather was warm enough for him to walk to our rendezvous dressed only in his shorts and carrying a towel. We, on the other hand, were required to be more modest in public. I stripped down to my swimming shorts immediately Mel and I got there, but she still kept her tracksuit on.
Danny guessed that something was afoot, but Mel teased him, talking about all sorts of inconsequential things, keeping him on tenterhooks. The feeling of anticipation built and built. The air crackled with tension. I remember I was thinking that Mel had better do something to ease Danny's growing sense of anxiety, or he'd go off 'pop', when she suddenly laid on her back and invited us to take her tracksuit bottoms off.
Danny swallowed hard when he saw that instead of her swimsuit underneath, Mel was wearing just her panties. Together we slid Mel's tracksuit down her legs and over her feet. Danny simply could not tear his eyes away from the rounded mound at the fork of her thighs and the dark shadow of her hairs behind the virginal-white cotton material.
"Can you guess what I'd like?" Mel said softly. She held her thighs closed tight and languorously rubbed them together. Her fingers crept down her belly and idly toyed with her pubic curls inside her knickers. Without giving us a chance to speculate, she crooned, "I would like you two lovely guys to stroke my legs all the way up from my ankles, right up until…until you find what you find! And, there's no need to rush, there's plenty of time."
By some miracle, Danny didn't cream his pants there and then! He was literally drooling! I felt more in control, but not by much!
Taking one leg each, Danny and I caressed Mel's calves and her shins, her knees and her thighs. And as we slowly moved towards the apex of these soft and smooth, yet shapely muscular columns, my sister spread her legs further and further apart. When we finally reached our goal, we gently ran our fingertips enticingly close to the tight leg holes of her panties.
Mel sighed. "Mmmmmm, that was very nice…I think you two deserve a reward."
She hooked her thumbs into the waistband of her pants and pushed them down at the front. Danny's eyes were bulging in his head as he watched her. "Oooops!" she giggled when she revealed the first hint of her dark, luxurious bush, and then pulled her panties back up again. The pained expression of disappointment on Danny's face deserved a photograph…but our family did not own frivolous things like cameras.
"Here!" said Mel, taking her hands right out of the way. "You two do it."
Danny's hand was shaking so much he could hardly take hold of the cotton material. Again, he was bug-eyed as we exposed Mel's glorious, hairy crown. The moisture between her legs made the gusset of her panties stick briefly to her pussy when we started to pull them down her legs and we had to tug them quite hard. When we finally got them off her, without thinking, I brought them to my nose and took in her scent.
"Do I smell nice?" Mel asked me.
"Fantastic!" I mumbled, suddenly realising what I had done.
Mel held out her hand for the scrap of material. She opened them out, uncovering the damp, slightly stained inner material of their gusset. She brought her panties to her nose and inhaled deeply. She looked straight into my eyes. For an instant, Danny ceased to exist. It was just Mel and I alone in a cocoon of silence. She put out her tongue and licked her own body's secretions.
