She!

'Oh, they went out just a little while ago,' Marshall said as he took his brother's directive to heart and pulled the string on my bikini bottom. 'Now lick her, Marsh.'

I tried half-heartedly to resist but I was firmly held on my back and I didn't really want to kick Marshall and possibly hurt him. He pushed my knees apart and followed his brother's directive. Mmm. It still felt good to have someone do that.

Billy continued to hold me down though I didn't fight anymore, feeling the younger boy's tongue lapping at my sweaty clit. I was almost at the edge that spelled no return when Billy spoke again. I groaned as I felt Marshall move away. I hadn't really heard what Billy said. Then, in a quick motion, he jumped off me and turned, placing himself between my still spread legs.

'Hold that arm,' he said, still holding my other wrist. Then I felt him probing at my pussy. I shook my head and looked down across my naked front to see him pressing his penis into me.

'Billy!' I said less convincingly than I would have wanted. 'Don't. You shouldn't.' I tried to free myself but couldn't as he plunged easily into me. He'd never done this before. 'Billy?' I moaned as he started to ride me wildly. It was different than any similar experience I'd had. Different and exciting.

Then I decided that two could play at this and twisted, pushing him over sideways and ending up on top of him. He still held my wrists though I could look at him below me now, my hair out of my eyes and dangling down over my shoulders and tickling my hard nipples.

I sat back and tried to pull my wrists free but he still held on. His penis was driven very deep into me in the process, though.

'Hey, sis?' I heard behind me from Marshall. 'I want to fuck you, too.' He had to have everything his brother had.

'You've got to wait your turn,' Billy said in his typical big brother tone.

'Huh uh,' Marshall said. 'Not if I put it in here.' He pressed against my asshole with a finger.

'No, Marshall!' I hissed. 'That hurts!'

'Well, I know,' he said and ran from the room. In a second he was back and squirted some suntan lotion on my ass. Then he took his finger and plunged it into me in a single stroke.

'No!' I screamed. 'Don't do that!' But he kept the finger in motion as he giggled with his triumph.

'I'll bet I could fuck you too if I put it in there. Huh?'

'No!' I snapped. 'No! Don't you dare.'

'Hold on, Billy,' he said and I felt him probing at my asshole with his penis. 'Hey neat!' he said. Billy pulled my upper body forward a little. 'Yeah, that's it,' Marshall said. I could feel his legs against my butt.

'Boys!' I said again more quietly. But now I wasn't sure I wanted loose. It felt great. Marshall's arms went around under my ribcage, locking and holding me. I was truly helpless to resist them even if I'd whole-heartedly wanted to.

Then I heard the key in the door and panic surged through me, making me work hard to try to get loose. I don't know whether the boys didn't hear it or didn't care.

'Somebody's coming home!' I hissed. 'Let me go.' Apparently Billy hadn't heard and just laughed as if that were another ploy to get free. Then I heard Minni at the entry to the family room.

'Oh, wow!' she said. 'What are you guys doing?'

'Minni!' I said loudly. 'Help me!'

'Hey, Min,' Billy said from below me. I looked sideways through my hair and saw her open-mouthed look at us. But instead of doing something to help me or to at least stop Marshall, she just sat down on the couch and stared, her mouth still open.

'They're both fucking you,' she said.

'Yes!' I screamed. 'Now will you stop them?' She just continued to stare, my frustration level rising. Billy pumped into me again and I moaned. Obviously, Marshall felt it or heard me and started pumping himself into me again with no related speed to Billy's.

Billy moved rather erratically in and out of me with slow strokes. Marshall pumped me like he beat off – fast and frenzied. Then Marshall moved his hand down and started rubbing my clit and, seeing that, Billy released my wrists and grabbed my nipples roughly.

I could only put my head back and feel the result of the double penetration and the manipulation of all my sensitive parts. Marshall suddenly came in my ass and I could feel come there. His first time. That set mine off in a big way, the world going dark for a second before it exploded. Billy was filling my cunt with his young sperm when I could feel my body again.

We all fell into a heaving pile that, I think, took Billy's breath away with the weight on his chest.

'Uncle,' he groaned.

'Oh, wow!' was all Minni could say. She hadn't even moved.

Marshall took pity on his brother and pulled free of me and rolled onto his back on the floor next to us. I lifted myself off him and realized immediately that I was leaking down my leg. I ran for the bathroom with my hand over my pussy, trying to hold it in so it wouldn't stain the rug.

I sat in the bathroom for a long time before I was reasonably sure I was not going to leak too badly. The two boys, in combination to my own contributions, had produced a fantastic amount of come.

Since I was nude, I grabbed Minni's robe from the closet before I left the room. The silky robe wasn't terribly effective, belting loose with just a little crisscross and not much length, but it was better than nothing. I grinned as I walked into the family room and saw them.

Again they were wrestling but this time Minni was the prime interest of their efforts and she never had been much good at wrestling. Standing in the middle of the room, Billy held her arms spread, his hands locked behind her neck in a full nelson. Marshall was in front of her, unbuttoning her dress down the front. I already knew what they were going to find since I'd been in the room for a few minutes when she was getting ready to go out with Paul. She'd decided to provide as little obstruction to anything he might want to do as possible. She was wearing only thigh high stockings under the dress.

'Sue! Help me!' she said as she tried to kick at Marshall as he stepped aside easily. I was sure she hadn't really meant to kick him with her high heel because he could have been seriously hurt.

'I remember how much help you were to me!' I said.

'Well! But help me, okay?' I just smiled. I could see her frustration building as mine had at the helplessness of wrestling with both the boys. They seemed to have nine sets of hands and every time you thought you were free, there was another one there to grab you. 'Marshall!' she yelled. 'Stop it! Billy, let me go!'

In a moment, Marshall had finished unbuttoning her dress – unscathed by her feints toward him. In a blur of motion, Billy changed his hold so he held her wrists behind her back and she winced with a little pain. That distracted her from what Marshall did, pushing the shoulders of the dress off and down her arms.

'Okay,' the younger boy said, wrapping both arms around one of Minni's arms. 'Pull it off her arm.' Billy did it before retrieving her wrist. Marshall repeated the actions exactly and the dress fell to the floor.

Minni is a full cup size smaller than me and with smaller pink nipples and considerably smaller areolas surrounding them. Her nipples still point upward when they're hard, like they were now, and the flesh bounces when she moves. They were bouncing now as she tried to free herself.

Billy put a foot behind Minni's ankles and pulled so they both fell to the rug. Neither of the boys had put their swimsuits back on and I could see now that they were both ready for more of what they'd started with me.

'Get the suntan lotion, Marshall,' Billy huffed through the effort of holding the squirming girl.

'What are you going to do?' she asked, her voice shaking.

'You know, sis. Come on.' She moaned as Marshall put his already greasy finger in her ass as he had mine.

'Ow, oh. No! No, don't do that!'

'Put some on me, Marshall.' I watched as the younger boy liberally applied lotion to Billy's dick and used his hand to spread it. Then looking under Minni almost like a mechanic looks under a car, he guided Billy to her asshole. She seemed to go berserk, her legs kicking and her body bucking.

'No! No! Billy! No! Marshall! Ow! Ow!' I wondered if it really hurt or if it was just the shock of the first time having this done to her. I went over and squatted down beside she and Billy's head.

'Are you really hurt?' I asked. She licked her lips and her bottom squirmed, but she didn't say anything for a
