Mom had stocked the freezer with a month's worth of frozen goodies, and Dad left me 500 bucks, and a credit card, with a warning not to use it unless I absolutely had to, and "There had better be a good reason, buster, or you pay it back!" He didn't need to worry. I know Dad, and he meant every word. There was the usual stuff - strict warnings not to touch the alchohol, bedtimes enforced, no inviting everyone over for parties, and all the dire parent warnings that go along with leaving sibs in charge of sibs. I sipped my wine, and moved onto the pool deck.

The sun felt fantastic, so I grabbed the lotion and started lathering it on. I must have fallen asleep, because the next thing I heard was the roar of the diesel as the school bus left for it's next dropoff. The wine must have been too relaxing for my 18 year old body.

I heard the front door, and saw Brian and Sue come in. Brian immediately headed for the basement, where I knew he'd be using the workout room. Brian was 2 years younger than I am, and gifted with a lean muscular body. In fact, we were all gifted in physical attributes, but Brian's eyes were blue, where mine and Sue's were brown. Fully half the calls we received were for Brian from girls at school, but he never seemed to return many of them. Sue received the majority of the rest, since her budding 15 year old body put some screen stars to shame. Since puberty about a year ago, I had been sneaking peeks at her gorgeous tits when she couldn't tell I was around (so I thought). Sue headed for her room, and came out on the pool deck a few minutes later clad in the bikini mom bought her this spring.

"Hey, Dave - great news! The school inspector came out today, and said we had to close it down for a week - something about some fire hazards and stuff. We've got a week off! At least 9 whole uninterrupted days all by ourselves." Although as her brother, I knew I shouldn't think about such things, the thought of uninterrupted parties crossed my mind, as my eyes wandered over her skin. "Great", I replied. "Whatcha want to do, then?"

She grinned, the "Well, for starters, I'm gonna get a killer tan so all the girls at school will hate me when I get back." She flopped down on the lounger next to mine and slopped on some Tropical Oil, massaging it into her legs and tummy. A cool breeze came up, and her nipples poked out of the skimpy fabric. I felt a faint stirring southward, and moved to hide her effect on me. She pretended not to notice (although I thought I saw the beginnings of a smile) and flopped back in the chair.

Right on cue, about 20 minutes later, Brian came out and joined us. Sweat was still dripping down his belly, and streaking his trunks, so he dove in to cool off. He came up about a minute later, and joined us. He grabbed good old Tropical Tan, and rubbed it on his chest and legs the way Sue had. "Hey, Dave - do my back, willya?" was almost simultaneous from both sides of me. We all burst out laughing. Sue flipped over and undid her bikini. Brian came over and lay where I just got up from. Sighing, and more or less wishing that Brian were elsewhere, I started rubbing the oil into her back. Moving lower, I massaged it into the backs of her thighs. By now my hardon was fairly evident, and I hoped Brian wouldn't notice.

No such luck. Sue had her eyes closed, but Brian didn't. He winked at me, and said "My turn, bro." The muscles on his back were still bunched up from his workout, so I helped work the kinks out of them while I applied the oil. I was concentrating on a lat, and jumped a little when a hand joined mine. "Looks like ole Bri really tensed these up this time", Sue said. "I'll help." A muffled reply from my brother indicated he was enjoying it, so we both worked down his back. I rolled him over, and Sue immediately started massaging his pecks. Her undone top flopped loose, and I could see alot more skin that I had for a while. The tightness in my trunks grew. Since Sue was occupied at the top, I worked on his thighs. Brian's trunks were tented out too, so Sue's tits were having their effect on him, too. Abruptly, she stood up.

"Jeez, guys, this is really working me up. I can't stand it any more." With that, she shucked the top, and the bottoms followed. I stood staring speechless at my gorgeous sister. I looked at Brian, but he just grinned and laughed. "Uh, Dave, Sue and I have a little surprise for you." With that, he stood and dropped his trunks. His now swollen dick popped straight out. "We've sort of been experimenting, and we'd like you to join us!"

With two fantastic bodies totally nude, and obviously sexually aroused in front of me, my cock did the natural thing, straining at the fabric. "Man, we will be so far into the doghouse if this gets out we'll never hear the end of it. No way!"......(cont)
