Day two of my insane weekend had included more spontaneous gay sex with my best friend. Only this time, that sex happened in his parents’ house, in his sister’s bed. I didn’t expect that, but then again, the rest of it had been a surprise too.

Casey and I had spent the Friday night before fucking in my bed. It was the first time I’d ever touched another cock. Or sucked one. Or had one in my ass. It was also the first time I’d ever came in a guy’s mouth before, or licked another man’s hole. Going to his parent’s house that Saturday was only supposed to be a quick errand, but it ended with a repeat of everything that happened the night before.

Plus, we had his sister Dani’s thong for some inspiration. Her lube was just icing on the cake–no pun intended.

But after we had finished, the sound of a car in the driveway caused us to scatter, sending me to the bathroom to clean up and Casey to the living room to act like nothing had happened. I managed to finish in the bathroom pretty quickly, which was a good thing. I didn’t want to be in the middle of trying to get myself together, while Casey’s mom or dad were knocking on the door, asking me how long I was going to be.

“Sorry about that, I’m just cleaning up from where your son fucked me in your daughter’s bed and came in my ass, I’ll be right out.” I stood in the mirror as I thought about that, and just shook my head. What the hell was I doing? More importantly, how did all of this feel so oddly normal?

I gave myself the once-over and after deciding I was good, I opened the door and headed down the hall. Casey was sitting on a stool in front of the kitchen island and casually surfing his phone, not giving any indication that he’d just swallowed my load. I almost laughed, and then suddenly wanted to take my cock out.

Not so normal, I know.

“So who’s here,” I asked.

Before Casey could answer, I felt two arms wrap around me from behind. “Surprise!”

My heart nearly dropped, as I turned to face a smiling Dani. She was wearing a low-cut top and flowy black skirt, plus stockings and short black boots. Her deep blue eyes stared through me, and her cleavage seemed to speak directly to me. I tried not to stare and quickly looked up, but I was sure she’d already caught me.

“Jesus,” I said with a laugh, “you scared the hell out of me.”

“She looks like that all the time,” Casey said behind me. “You get used to it.”

Dani frowned as she said “ha-ha, fuck you.” She took a step closer to me, her breasts nearly touching my chest. “Haven’t seen you in a while,” she said. “You still seeing Kate?”

“Sort of,” I answered. She stared at me for a moment before finally shrugging her shoulders.

“Yeah, I don’t know what to make of that.” She gave me a wink, and as she moved around me, her fingers grazed the side of my leg. I didn’t think too much of it in the moment, but it was intentional contact. Was she flirting with me?

I grabbed a seat next to Casey, as Dani dug through the fridge. She pulled out a bottle of water and pointed it in my direction. I gave her a nod and she sat handed it to me.

“So,” Dani said, “what are you two doing today?”

I felt Casey give me the side eye as I answered. “Not much. We hung out last night, and he had to grab his mail.”

Dani closed the fridge door, and opened her own water bottle. “Sleepover,” she said between sips, “that’s cute. You guys do each other’s hair?”

Casey’s side eye had now become a full-blown stare. Finally, I looked at him. “You said you wouldn’t tell,” he said blankly.

I laughed at him, and Dani laughed too. “Nerds,” she muttered.

“We’re not staying long,” Casey told her. “Probably heading back to his house.”

“What are you doing tonight,” I asked her.

Dani shook her head. “Well, my date’s already canceled so, nothing, I guess.”

“First date or second date?” I asked.

She held up two fingers. “Second. Nice guy, too.”

“What happened?” Casey asked. “Didn’t fuck him on the first date?”

I was in mid-drink, and nearly choked on my water. “Jesus,” I laughed under my breath.

Dani stared at Casey, her eyes narrowing. “No, but he had fun.” she looked over to me, and didn’t speak until I locked eyes with her. “He would’ve had more fun tonight.”

She winked at me again, and brought her water bottle up to her lips. She subtly licked around the top before slowly taking a sip. She let some drip down her chin and it ran down to her chest. She never broke eye contact. Casey was still in his phone, and didn’t see any of it. I grinned at her, as my cock began to stir in my jeans.

Yep. Definitely flirting with me. ‘Easy,’ I told myself. ‘Just be cool.’

“You should come over,” I suddenly said. Casey grunted under his breath and Dani gave him the middle finger in response.

So much for just being cool.

“Yeah?”

“Yeah,” I said with a smile. “Why not? We can watch a movie or something.”

Casey shot a quick glance at me, his eyes wide. Dani took no notice of him and it was all I could do to not look away from her. I can’t say I had an actual plan in that moment, but I can’t say I didn’t, either. I only knew I was hard and Dani was hot as hell.

Then there was the story Casey told me about cumming all over her one night when she was drunk and begging him to fuck her. The fact that he told me right before making me cum was enough to throw all common sense out the window. Plan or no plan, I wanted them both.

“Such a gentleman,” she answered. “What time are we talking?”

……

After hanging out in his parents kitchen for a while and flirting with his sister so much I could barely walk, Casey and I headed back to my house. We didn’t talk much on the way and honestly, I didn’t know what to say anyway. I was sure he knew what I was thinking and what I was hoping would happen.

Did he want it too? Or was the talk about the three of us together just talk after all? Dani was only his stepsister, but maybe that was too weird for him, even though they’d had one previous encounter?

I showered when we got home and we were halfway through some Chinese takeout in my living room when Dani knocked on the door. She came in and sat between us on the couch. It could’ve been a little awkward, considering her stepbrother and I sat in the same spot naked the night before. But at that point, I was too focused to care. All I could think of was getting into bed with her.

But as the time ticked by, we were no closer to doing much of anything. I wasn’t even sure how to begin, really. I mean, what was I supposed to say? “Oh hey, Dani, how’d you like a threesome with your brother? It’ll be fun, you’ll see!”

Casey finally stood up and stretched, yawning as he did it.

“Long night last night?” Dani asked.

“Something like that,” Casey said, looking down at me. I kept a straight face when I looked back at him. “I’m going to grab a shower,” he said. He headed down the hall to the bathroom, leaving me and Dani alone. Everything was good at first, just has it had been all evening. But when Casey shut the door and eventually turned on the shower, Dani suddenly turned to face me on the couch.

“So, what happened here last night?”

I shrugged my shoulders innocently. “Not much, we just hung out.”

“Ahh,” she answered. She slipped off her shoes and socks as she spoke, never breaking eye contact with me. She kept staring at me and it was almost impossible to look away. Her blue eyes were beautiful and I was getting lost in them as we sat there. “So,” she said in a half-whisper, “ a funny thing happened after you guys left today.”

“Yeah?” I asked innocently.

“Yeah. I found my bottle of lube half open and dripping on my bed. Plus, I found this.” She pulled her black lace thong from her pocket and held it up for me to see. It was the same thong Casey and I used earlier that day in her bed.

I froze. I didn’t know what to say.

“It’s dried now but it was wet. Wet and sticky. Do you know how it got that way?” Dani laid the thong on my lap and spoke before I could answer. “Did you maybe have some fun in my bed?”

My heart was racing and I was speechless for a moment. Finally, I spoke.

“Maybe. I mean, well, more than maybe.” She smiled at me and began to run her fingers through my hair. “Okay, I did,” I finally admitted. “It wasn’t planned, but I did.”

“So, by ‘I’ you mean…” her voice trailed off as she waited for me to speak.

There was no way I was answering that. How could I?

“Nothing to say? Going to leave me hanging?”

“Sorry,” I blurted out. It was all I had.

Without speaking, Dani slowly took off her shirt, exposing the black lace bra that barely kept her breasts in. My heart started pounding in my chest as she smiled at me again. “It’s okay,” she said, “I’m not much of a talker anyway.”

With that, she kissed me, sliding her tongue inside my mouth. In one smooth move, she straddled my lap and reached behind her, unhooking her bra and tossing it on the floor. Her tits were so big and her nipples were rock hard. I took them in my hands and kissed each one, running my tongue across each nipple before sucking them. Dani’s breathing was fast as she eased back, letting me take my time with her gorgeous tits.

Then she came forward again, grinding her crotch on my erection. I ran my hands up and down her back and she shivered as she stuck her tongue into my ear. I put my arms around her and shifted, moving her from my lap and laying her down on the couch. I grabbed her skirt and pulled it up, revealing her clean shaven pussy and no panties. She was smiling up at me as she unzipped the back of her skirt, pushing it down toward me. I pulled it free from her legs and threw it on the floor.

I kissed her mouth, her nipples, and then ran my tongue down her stomach to her pussy. Dani let out a loud moan as I began eating her out. She tasted so good and she was already soaking wet. I opened her up and began tongue fucking her hole as she grabbed the back of my head.

“Ooh fuck,” she whispered, “so fucking good.”

I looked up at her and she was sucking on her left nipple. I gently pinched the right one and she instantly reacted by moving her hips up and down, fucking herself with my tongue. We stayed that way for a few minutes before I stood up and unbuttoned my jeans, pushing them down to the floor. She quickly sat up and took my hard cock into her mouth.

The sensation of her tongue circling my cock as she sucked me was insanely satisfying and for a split second, it occurred to me that she was just as good as her brother, if not more. The thought of that made me even harder and I began to fuck her mouth. She held still as I put one foot on the couch and began going deeper, hitting the back of her throat. Then she grabbed my cock and took it out, lifting it up to suck on my balls.

“Oh fuck yes,” I said and she moved to the floor, getting under me. I bent over slightly as she ran her tongue from my sack up to my ass. She began licking and sucking on my asshole, sloshing her tongue back and forth as she jerked my cock with her right hand. It was all I could do to not shout and that was when I looked toward the hall and saw Casey.

He was naked and had dropped his towel to the floor. His cock was hard and he was stroking it as he watched us. I motioned to him and he came to the couch. I got on my knees onto the cushion and half-expected Dani to say something, maybe even to ask what I was doing. But when she saw Casey, she instead moved with me, eating my ass and grabbing my cheeks with her hands. Casey stood in front of me and I took his cock into my mouth.

There was no turning back at that point. I was sucking Casey’s cock while his sister’s tongue was in my ass. This was what I wanted and it was everything I could’ve hoped for. But even as I worked on Casey’s cock, it suddenly struck me that maybe Dani would only go so far. Would she actually fuck Casey, or was I going to be the one in between? But then she said it.

“I want a turn.”

Her voice behind me made me stop, while also causing Casey and I to lock eyes. I took his cock out of my mouth and we both stared at each other. His mouthed the words “oh fuck” and I gave a him a quick nod as if to say “I know!”

I moved to the side and Dani slowly eased up on the couch. She looked first at me, then at Casey. She leaned in and kissed me, putting her tongue so far down my throat I gagged a little. She slid a finger inside me as we kissed and grabbed Casey’s cock with her other hand. Then she pulled back and took her stepbrother’s cock into her mouth.

Casey threw his head back and moaned loudly, propping one knee up onto the back of the couch as he did it. Dani expertly sucked him, taking it all the way in and choking on it. Then she looked up at him as he began moving his hips in rhythm with her mouth. Suddenly she took it out and pointed it toward me. I greedily took it and started sucking him.

“Jesus fuck,” she said louder than she probably intended. I kept sucking his cock and Dani kept her hand around the base of it. She began jerking it back and forth and I stopped, letting her do all the work. Then she took it out and put it back in her own mouth. She began going deeper with her finger and started moving back and forth as she worked in my ass. Then she took it out and I sat under her, positioning my cock near her pussy.

Dani stopped sucking and looked down at me. She grabbed my cock and rubbed it on her clit. I sucked her tits and as she guided me inside her. She moaned as it went in and whispered in my ear.

“I’ve wanted this for so long.”

“Me too,” I said.

She kissed me, her hand stroking Casey as she began rocking up and down on my cock. Her pussy was so warm and tight and it was all I could do to not hit a quick burst of speed and just fuck her until I shot inside her.

Dani started sucking Casey’s cock again and I reached behind her, playing with her asshole as I fucked her. We stayed in that position for what seemed like forever, until I heard Casey say “Come on.”

He turned and headed down the hall to the bedroom. Dani pulled back but instead of standing up, smiled down at me. “Fuck me now. Now!”

I grabbed her hips and started ramming up inside of her. She started pushing down, causing our bodies to audibly slap against each other as she rode me.

“Jesus goddamn fuck, oh my god,” she shouted as she bounced up and down. Finally, she stopped and stood up. Before I could stand, she turned around and grabbed her ass cheeks. She spread them wide and bent over, pushing her ass into my face. I slid my tongue in her pussy, then her asshole. She was moaning as I ate her and then looked over her shoulder at me. “Are you ready for this?”

“Fuck yes,” I answered. Then we moved to my bedroom.

……

The lamp was off in the bedroom but the hallway light gave us just enough to be able to see. I thought about turning it off too, but thought better of it. I wanted to see this. All of it.

Casey was lying on the bed, his hard cock resting on his stomach. Dani moved in front of me and as she did, she handed me the bottle of lube that Casey and I had used when we fucked. She climbed onto the bed, getting between Casey’s legs and began sucking his cock. I got on all fours behind her, keeping the bottle in my hand as I slid into her pussy. I slowly started fucking her and I could see Casey’s face as she sucked him. I realized he’d probably been fantasizing about that moment for a long time.

Watching her suck him was the hottest thing I had maybe ever seen and I couldn’t wait to watch him fuck her. I also couldn’t wait until he was fucking me.

After a few minutes of Dani slurping on Casey’s cock and moaning as mine went deeper and deeper into her, she stopped and began moving forward, straddling Casey. She stared at him as his hard cock teased her pussy. I watched them and could see they...
