AUTHOR'S NOTE: I wasn't entirely sure what category to post this story in.

STORY:

"Tyler has a crush on me, doesn't he?" I asked my little brother. He was sitting in a bean bag chair on the floor of the living room, playing a video game.

My brother turned toward me with a funny look on his face. I shrugged, grinning. He turned back to his game and I glanced up at the screen. He was good at this game. He and Tyler had been playing for hours. I didn't mind watching them play. I was only partway paying attention, since I was also dming with a boy from school. Our conversation was getting pretty hot, to be honest. But he hadn't sent me a message in a while.

Tyler walked back into the living room and I stared at him. He glanced at me, but quickly turned away when he saw me looking at him. My brother's friend was actually really cute. He was short for his age. I guess probably about 5'5" or so. He had messy blonde hair that he constantly brushed out of his eyes. It covered his ears on the sides.

The two had been best friends since the first grade. They were both eighteen now, in their senior year at high school, yet somehow I still found myself getting roped into "babysitting" them during the summer. I was twenty-one and had just finished my third year of college. I didn't mind, usually. Unless I had other plans that I had to cancel. This particular weekend, our parents were at a lake house with some friends from college. I wanted them to take us with them, but my mom had a heart to heart with me and confessed that they would probably be using drugs and they didn't want my little brother to see that.

My brother, Justin, was several inches taller than Tyler. He had dark hair, almost black, just like mine. He was cute too. My friends always gloated over him when they came over. I sat back and watched the two friends as they played their game. My mind wasn't all the way in the right place, though, after the hot conversation I had been in the middle of with Jordan. That's the boy from school. We had been talking about doing sexual things together. Honestly, I really just wanted to give him a blowjob.

My phone buzzed and I snatched it out of my lap and checked the screen. My jaw fell open when I saw what he sent me. It was a picture of his dick. He had his hair trimmed really short around it, which I liked. I honestly wouldn't even mind if he shaved it all the way down to the skin. I leaned closer, examining it. It was hard and looked really big. Just staring at it made me squirm on the couch. My pussy felt warm. Oh yeah, I was definitely horny.

I sent back a dm that read: "yummy."

A few seconds later, his response said, "yeah? want some?"

Jesus. I felt pleasure starting to pulse between my legs. I bit my lip, looking up at my brother and his friend. They were intent on their game. Good. Reaching one hand down, I slid it into my sweats and quickly nestled my way to my pussy. I gasped at the shock of pleasure that erupted. And wow was I fucking wet! I caught Tyler's movement out of the corner of my eye and yanked my hand out of my pants. He glanced at me and I stuck my finger in my mouth. He frowned, but I didn't care. My pussy juice was exquisite and tasting it only added to my horniness.

I sent another message to Jordan, "yep."

After a pause, he asked, "serious?"

I sat up. Was he serious? My hands were shaking as I typed into my phone, "if you are."

"now?" he typed back.

I looked up again at the two teenage boys a few feet away from me. I wondered if I could sneak up to my room and let Jordan in the window so I could blow him without them finding out. It seemed dangerous. But maybe... an idea came to me. I typed another message, "tonight. midnight. can you come?"

"fuck yeah," he answered back immediately.

Fucking hell my pussy was dripping. And I was shaking. This was really happening. I mean, it's not that it was my first time giving a blowjob. But I had never arranged something like this in my parents' house. So sneaky. And it had been almost a year since I had a boyfriend. Not to mention I wasn't actually dating Jordan. He had just sent me a dm a few days ago. Before that I didn't even think he knew who I was. I sent him my address and told him which window to come to. Then I checked the clock. It was a little past eleven.

"Ok guys," I said to the room. "It's almost time for bed."

"What??" Justin said, turning toward me. "But it's Friday! Mom always let's me stay up until at least midnight."

My mom still treated my little brother like he was twelve sometimes, which annoyed me, to be honest. But he was still in high school, so I felt at least some responsibility to follow the rules they had set for him. Sighing, I knew he was right, though. Mom did usually let him stay up until midnight on the weekends.

Briefly, I thought about telling him that I wanted to have a boy over, but I was afraid he would ask too many nosy questions and then end up telling mom. She had made it very clear that even though I was an adult, I was not to have any boys over while I was staying under their roof. But I had to do something. I was so fucking horny. I noticed Tyler staring at me. At my breasts, actually. My dark hair was long, but I had it tied up in a pony tail, so the front of my chest was unobstructed. I knew my outfit was sexy. I was wearing a cut off t-shirt. It was a size too small and my breasts were a large b cup, so I knew they were pressing pretty firmly against the fabric. Fleetingly, I wondered if my nipples were showing.

An idea popped into my head. I probably should have snuffed it out, but I was so desperate to get them to bed so I could let Jordan in that I pushed forward with it. "Tell you what," I started. They were both staring at me. Tyler's face had lifted up to meet mine, but he had a slight flush in his cheeks. Good. I leaned a little closer to them, feeling my shirt tighten up against my breasts. Both pairs of teenage eyes drooped down, glancing at them. Perfect.

I whispered and their eyes flicked back up to mine. My words made their eyebrows lift up. I said, "If you guys get ready for bed and in your room in the next ten minutes, I'll let you see my tits."

Both boys looked at each other. My brother's face turned bright red. Tyler started grinning, although he was clearly trying to hide it. I decided to push a little more so I added softly, "My offer is about to be rescinded."

Tyler stood up abruptly and I couldn't help but notice his teenage boner pressing against his shorts. I would have smiled over it, except it had a rather unexpected effect on me. A strong tingling sensation started buzzing in my crotch. I felt like something was tickling my clit. I almost gasped but managed to school myself to calmness. Tyler turned toward my brother as he stood up too. I glanced at Justin's crotch to see if he was hard, too, but I couldn't tell from the angle he was standing.

When both boys turned toward me again, I raised an eyebrow at them and opened my mouth but they quickly scrambled out of the living room. They were so blatantly staring at my boobs I almost started laughing. Young, horny boys. Exactly what this twenty-one-year-old babysitter needed. My pussy throbbed with another pulse of pleasure as if to remind me that I was horny, too.

I waited a few minutes and then made my way down to Justin's bedroom. He had a full size trundle bed, with a second bed underneath that could slide out on a little track. When I walked in, they were both sitting up on the top bed. They had changed. Both boys were wearing pajama style sweats and a t-shirt. I paused in the doorway, staring at them. Tyler had his hands covering his crotch, so I couldn't tell if he was hard. Justin's pajamas were too loose to notice anything. I felt a little disappointed.

"Ok, you guys earned this," I announced as I stepped a few feet into the room, stopping a little way away from them.

Tyler had a very serious look on his face, although the creeping red flush gave away his embarrassment. My little brother looked eager, which I was actually a little surprised about. I never thought about him thinking of me in a sexual way. But seeing how he was looking at me then, I briefly wondered if he had ever thought about me while masturbating. For some reason, thinking of that was like fanning a glowing ember in my crotch. I sucked in a breath as the wave of arousal ran up my body.

"Ready?" I asked. When they both nodded, I crossed my hands across my stomach and grabbed the hem of my shirt. I held still, watching their expressions. Their eyes were glued to my breasts. Tyler licked his lips and I noticed my little brother's breath catch. His lips were parted just a little. They both stared so intently, it almost made me laugh. But the amount of arousal it was creating overwhelmed any thought of poking fun at them.

Lifting my hands, I slowly revealed my naked chest to the two horny boys sitting on my brother's bed. Their eyes grew wider with every inch of skin revealed, until they were openly gaping, mouths hanging open, as I held my shirt up to my chin, giving them an ample view of my bosom. I watched them as they stared at my breasts. I knew I had nice breasts. They were B cups, but perky and nicely round. My nipples were light pink, with areolas that circled them that were about an inch and a half wide. Their pink edges faded nicely into the surrounding flesh of my breasts, and I had been complimented on them multiple times.

As the two boys stared at my naked chest, my body shivered involuntarily. This was so fucking hot. I couldn't believe it. I never would have suspected. Jesus, I was getting short of breath. And my heart was fluttering like crazy. I couldn't help but look at their laps. My own mouth opened a little, until I caught myself and snapped it shut. Both boys were sporting a sizable boner, jutting straight up and poking at the fabric of their sweats.

I lowered my hands, tugging my shirt back down over my breasts until they were hidden once again. I stared at the two boys as they clearly reeled. Neither one said a word, nor moved. They were like two frozen statues, faces etched with lust. Good god, now I wanted to help them. I bit my lip and glanced at the clock on my brother's nightstand. It was 11:38. Shit.

I should have just left it at that and left the room. But I couldn't. A new idea had already formed in my mind and I was insanely curious if they would play along. In their current aroused states, I decided they probably would. I spoke before I could change my mind. "You boys want to play a little game?" I asked.

They both nodded immediately. Yep. I definitely had them. Like putty in my hands. I smiled, looking back and forth between the two of them. I could still see the outline of their little boners. They hadn't budged an inch. In the back of my mind I wondered what they would do if I just left the room. Would they masturbate in the same room with each other? Well, I was going to see just how far I could push things.

I took another step toward them and lowered my voice, eyeing each of them in turn as I spoke, "Do you boys want to touch my breasts?"

Tyler started nodding immediately, and my little brother was only a few seconds behind him. "Yeah," Justin said, although his voice squeaked a little. I smiled at him.

"Ok," I said, taking another step closer. Then I leaned forward, letting my shirt snug against my breasts once more. Both boys' eyes drooped again. I leaned a little more, making sure they had a good view of my cleavage. Justin squirmed and I saw his little boner twitching a little. I looked back and forth between them as I whispered, "Take your clothes off and I'll let you touch them."

Tyler immediately looked at Justin, but my brother was staring at me. Into my eyes. He had a look as if to ask, "Are you joking?" I stared at him intently, unblinking. Until he slowly nodded and turned toward his friend. Tyler mouthed, "Can we?" and my brother nodded.

Straightening, I smiled as I watched the two young boys quickly strip out of everything except their socks and underwear. I spent a minute admiring their skinny bodies. Tyler's nipples were so tiny, they were adorable. And I desperately wanted to lick them. Jesus, Leah. Get yourself together! But I couldn't help it. I was beyond merely aroused. I could literally feel my pussy dripping inside my panties.

Swallowing, I whispered another request, "I meant everything, boys."

The two eighteen-year-olds didn't even hesitate. I watched as they both lifted their butts up at the same time and pulled their underwear down their legs. It was all I could do to keep from letting my jaw drop to the floor as I stared at the two beautiful penises that were suddenly revealed to me. Thoughts of Jordan's penis were long gone from my mind. Here were two perfect, hard little boners staring right at me.

I quickly reached down and grabbed my shirt, yanking it up over my head. I took it completely off and threw it to the floor. Both boys were riveted on my boobs again. My brother's penis was twitching. I walked forward and sat down on the end of his bed near his pillow. Then, swinging my legs up, I watched as both boys turned their bodies, never letting my breasts out of their sights. Their eyes glistened with lust.

"Ok," I whispered. "You can touch them now." I held my breath and both boys climbed across the bed and knelt on either side of me. I stared at my brother's penis as his hand reached out tentatively toward my left breast. At the tip, I saw a tiny bubble of glistening liquid oozing out. His hand brushed against my nipple and I couldn't stop from crying out, "Ooohm!" The pleasure that shot through my body was more intense than I expected. I felt his cautious fingers probing at my flesh, tickling my nipple. And I couldn't stop staring at his hard penis. Actually, it was quite a bit bigger than I expected. Both of them were. Justin's penis was probably about seven inches long and about an inch and a half wide. The tip was taut and shiny, and the little bubble of liquid had started to drip down the head.

Just then, another hand brushed my other nipple and my pleasure soared beyond anything I had experienced before. I looked over at Tyler and saw him staring at my breast with such a look of awe that it reminded me of someone seeing fireworks for the first time. That is, if that person was also filled to the brim with sexual arousal and horny as fuck. Tyler's hand was shaking, but he was gently massaging my breast with it. Ripples of pleasure kept surging down my chest into my pussy. I gasped audibly, several times in a row.

Finally I turned my attention to Tyler's penis. It was bigger than Justin's, but not by much. I didn't see any liquid at the tip like my brother's, but his boner looked just as inviting. Good god I wanted to suck these boys off! I let the two of them continue working their hands on my breasts for a few minutes, privately enjoying the sensations. I moaned several times, which only seemed to make them try harder.

Finally, I needed more. I grabbed both their hands and gently lifted them off my breasts. I was panting, but so were they. My little brother's penis was glistening now. More liquid had leaked out, and another bubble was forming at the tip. God I wanted to taste that. But I had something else in mind instead.

Barely able to catch my breath, I looked back and forth between the two boys and then whispered, "Do you boys want to touch my pussy?"

Tyler's eyes looked like they were about to pop out of his head. His penis started twitching like crazy, too. Justin whispered near my ear, "Yes."

I smiled inwardly. I had them. I knew my brother was a virgin, but judging their reactions to this whole experience, I was confident that Tyler was, too. Two horny eighteen-year-old virgins. I knew they would do anything I asked. Drawing in a shaky breath, I scooted back a little and then gave one final, meaningful look directed at each of them in turn. Then I whispered, "I want you to let Tyler suck you off."

It was Justin's turn to look like his eyes were going to bounce right out of his head. He didn't say anything, but his expression showed all the surprise in the world. He swallowed hard. Tyler hadn't said anything, so I slowly turned my head toward him. When I reached him, I saw his eyes staring down. Not at me. At Justin. At Justin's penis. Tyler had an extremely curious expression on his face. He didn't look upset, or embarrassed. Just... thoughtful?

"Well?" I whispered to the room.

"Ok," Justin said, looking at his friend.

Tyler shrugged and whispered, "Ok."

My pussy throbbed with pleasure. This was happening. I glanced again at the time. It was 11:51. Ah fuck. Jordan was going to be there any minute. But there was no way I could stop this little performance. I was too invested in it. Jordan could go to hell for all I cared. Jesus I could barely breathe.

Justin scooted forward a little and then laid on his back, his knees up and legs spread a little. He was lying perpendicular to my legs, right in front of my feet. I tilted my head sideways to get a better view of his twitching penis and then waited. Justin and I both stared at Tyler. He licked his lips, suddenly seeming uncertain. "Tyler?" I called his name softly. When he turned toward me, I leaned back a little and made a show of sliding my hand down my stomach and into my sweats. I couldn't help from moaning as I diddled my pussy for a few seconds. That was long enough to completely coat my finger with juice. I was breathing heavily when I pulled my hand back out. "This could be yours," I whispered, slowly turning my hand and showing him my glistening fingers, covered in pussy juice.

He swallowed hard and nodded. Then he sort of threw himself forward clumsily, dropping down between my brother's legs. I scooted back, lifting my head higher to see. Justin's penis was twitching like crazy. Another bubble of liquid sprouted up at the tip and immediately started oozing down the side.

Tyler took in a deep breath and then dove forward, kissing the tip of Jusin's penis. My little brother moaned softly. I stared at the scene, watching as Tyler's tongue stuck out between his lips and slowly licked the tip of Justin's cock. Oh my god this was the hottest thing I had ever seen. My pussy throbbed with pleasure as I stared. My little brother moaned again and suddenly Tyler's lips opened and I watched in shock as he pushed forward. The tip of Justin's penis disappeared inside Tyler's mouth. Fuck! I couldn't stop myself from sliding my hand down inside my sweats again, probing my fingers down between my legs. My pussy was so wet! Tyler's cheeks started moving as he sucked and my brother started moaning louder. The pleasure in my pussy grew so fast, so intensely, that I cried out.
