I did want some more quiet time with Barb, so I only put up a token resistance before I surrendered. I hoped that my actions would fit with whatever understanding mom and Barb had going on. Barb and I really need to spend a bit more time so I understand what is going on, and how I should be acting; I didn't want to come off like a nun in a bordello, or a whore in a church. I thought that Barb and I better start our conversation as soon as possible so when we reached the bottom of the hill and turned to head to the waterfall, I opened our talk.
"Barb, how am I supposed to act around mom and dad now? After mom telling me the other day about you two having sex talks, and since you talked with her about the pictures they took, just what am I supposed to do? I don't want to screw this up and get us in trouble."
"First off, Tom, you aren't to do any 'acting'. You just 'react' the same as always; you need to do the same things you've always done around them. If you start acting funny at all, mom would know it right away. I doubt that mom will start any more conversations with you about sex and she probably didn't say anything to dad about talking to you about sex, so he won't either. If for some reason she does say something, it would be reasonable for you to be reluctant to talk, just take a second to think if it is something that she has already spoken with you about, and by all means, always tell her the truth about how you feel about stuff. Just don't bring up anything about our sex stuff.
"While I'm thinking about it, I didn't tell mom that you'd seen the pictures, I told her that I'd found them. I figured that would be less embarrassing for her. So don't say anything about seeing them."
We continued walking and when we arrived at the waterfall pool, as her guardian, Barb had me cross the bridge first to check for killer rabbits and such before she'd hop down. I laid the big towel down on the rock for Barb and put her sunscreen lotion and an extra towel down beside it. I carried the rest of the pack over to the rock table and chairs that were located just in the shade. I'd stay mostly in the shade since I didn't tan well at all. But I kept an eye on Barb as well so I wouldn't miss anything as she peeled off her clothes and bikini to sun. I definitely didn't want to miss when she would request help with applying the sunscreen lotion, my favorite job as her guardian while we were here on vacation.
I pulled out my magazines and proceeded to start reviewing what was in the second one. It turned out that I had unknowingly picked up a magazine dedicated to nudism. Although I'd never thought of it before, since I had never spent much time naked, I could very easily take up a nudist lifestyle if I had the chance. The freedom of not wearing clothes looked somehow right and good, and it would save me time and effort and money spent on clothes and doing laundry. Yes, that would be nice in many regards. That lifestyle only required money, and therefore a job to earn enough of it.
Barb had laid down on her back to sun first. I had barely finished looking at the listing of articles in the magazine before she got back up and walked over to stand under the falls. I had to watch her as she wiped her hands down over her body making sure that the water cooled all of her skin. My eyes just wouldn't let me pull away and continue reading in the magazine.
That's why I immediately saw when she made that come here signal, you know the one, where you curl in the hand, starting with the little finger, then the ring finger, then the middle and finally the pointer finger. I was up off the seat before the middle finger started its curl. By the time I was wading across the pool, I would have been very embarrassed of the tenting of my swim trunks, except that I knew what we would be doing this afternoon, and therefore had taken them off before sitting down.
If her smile was the indicator that I thought it was, Barb was not disappointed in the view as I approached. And that was confirmed when she jumped at me, wrapping her arms over my shoulders and behind my neck, and locking herself against me by crossing her ankles behind my back. Of course, I had thrown my arms around her when she did that to be sure she didn't fall, placing one hand on the middle of her back, and the other halfway under her butt.
She did however, allow herself to slide down slightly until her butt was touching on the top of my prick, aligning her ass crack with my erection like looking upside down at a hot dog on a bun. By pushing and pulling with her legs, she slid closer and farther away from my belly. It felt wet so there wasn't any friction, but it wasn't a water kind of feeling... No that was her juices that were feeling so nice on my prick.
She kept one hand behind my neck, but the other she slid down between us and caught the root of my prick and pushed herself slightly further away as she aligned her pussy with the head before sliding back tighter against me, impaling herself on my prick. I think she thought that she was wet enough and stretched enough to be able to get my prick to slide in, in one smooth motion, but she was just too tight for that to happen. She did do it in just three pulling movements but I don't think she realized it since on the start of the third pull; she started shaking and moaning as she went into her first orgasm.
I managed to stand there through her first orgasm, but I couldn't kiss her lips since her head was below my chin, and I couldn't caress her tits since I was afraid to move my hands from her back or below her butt. I pressed my mouth to the top of her head and I did manage to rub her back a little and squeeze one butt cheek while the other was resting on my wrist. I dared not let myself come while we were standing like that, afraid I'd drop her or slip and fall with her ending up on the bottom when we hit.
While she started coming back around, I turned and walked us back to the towel. I sat down on the edge of her sunning rock with my feet in the pool, allowing Barb to sit on my lap until she became fully aware again. With my hands now free, I reached behind and uncrossed her ankles and lay her feet on the rock to either side of my butt. Grabbing her hips, I started to slide her back from my groin. She stopped me from sliding her any further when the tip of my prick was just about to come out of her pussy. If I tilted my head down and leaned her back and myself forward, I'd be able to kiss her on the lips. So I moved my hands from her hips and started to massage her tits, plucking at her nipples between squeezes while I kissed her several times.
Barb was trying to scoot forward to get more of my prick in her pussy and I already had my right hand tilting her chin up so I could still keep kissing her. Her head was laid back and she was looking straight up into the sky. I had to put my left hand against the top of her belly to push to hold her back or I'd lose contact with her lips; I was already scrunched as far as I could get. She was pulling with her feet behind my hips and her hands up under my arms and behind my shoulders. One of us was going to lose this push-pull war and it was going to be me since I wanted my prick buried in her also.
Finally I just kissed her lips one last time and kissed over her cheek and under her left ear and licked up her ear and nipped at the upper tip of that ear, then kissed just off the tip of her eye. I kissed the tip of her nose and then just off the tip of her other eye. I tried to nip at the top of her other ear but missed and had to settle for a kiss on her forehead before a last kiss on the top of her head as I released her chin from my grip. With my left little finger and ring finger, I caught her right nipple while I stretched my hand to catch her left nipple between the tips of my thumb and pointer fingers. I moved my now free right hand around and down her back and aligned my middle finger with her ass crack, sliding it down and under to lightly touch her little pucker. I would be able to use that hand splayed out under her ass to provide a small lifting motion to allow her to slide easier on my lap.
Barb tried so hard to lick and suck at my nipples, but with both of her nipples being pinched between my fingers, and with her pucker being pressed by the middle finger of my other hand and her clit rubbing along the top of my prick as she slid forward burying about another inch or two into her pussy, she couldn't stop herself from starting into her second orgasm, a stronger one even than the first that had rattled her such a short time ago. Her scream was muffled as she slammed her mouth against my chest and shook as though she were enduring an 8.4 earthquake at the middle of a suspension bridge.
