“What the fuck!” Anna yelled. In retrospect, I think she more hissed than yelled, but in the moment, it was the loudest fucking three words I’d ever heard.
There was a brief moment where Liv and I both simply froze in shock. Unfortunately for us both, I was past the point of no return.
“Fuck.” I said, much differently than I had a second ago. I came, semen shooting out of my dick into Liv, even as Anna stared at us dumbfounded. From where she stood, there was no hiding anything. She got treated to a full view of my hard cock deep inside my sister, my hands firmly on her ass. My cock twitched, and I felt cum dripping. Realization finally launched us into action, Liv jumped off of me, my wet dick slipping out, and both of us grabbed wildly for the sheet to cover our naked bodies.
“Anna?” Liv gasped, her voice a mix of confusion and terror.
“Don’t Anna me. You two were just fucking!” She let herself into the room, shutting the door behind her. “I fucking knew it! I fucking knew you were in the bathroom way too long.” Anna muttered to herself, shaking her head in disbelief.
“Shh shhh.” Liv begged her. I was too stunned to speak.
“Shhh yourself. My mom sleeps like a rock. Though even then, I’m hardly being louder than you two were.” Anna stared at us as we stared back at her from under the sheet, then just another; “What the fuck! You two have been fucking?”
“We can explain…” Liv said, her voice trembling. “Just please Anna, listen to us, we can explain. Just don’t tell anyone Anna, please.”
Anna stood at the foot of the bed, her face a mask in the faint light. I swear my heart had stopped. I was also painfully aware of an ache in my dick. I don’t think I’d ever been that shocked out of an orgasm. It was the most peculiar dichotomy, my brain telling my body to be terrified, as I’d just been caught fucking my sister, and my dick telling my brain to relax, and let it enjoy itself.
“Alright then, explain.” Anna crossed her arms expectantly.
“We were just… it was late one night… we didn’t…” Liv stuttered, and I realized she was on the verge of tears. And I didn’t know how to comfort her. That was the breaking point. I was suddenly uncomfortably aware of what was happening. We just got caught fucking. Anna was one word to our parents away from ruining our lives. We were suddenly completely and utterly at her mercy. Thankfully, Liv had just spent almost three days straight reconnecting with her previously estranged best friend. And Anna couldn’t bear Liv crying anymore than I could.
“Oh Livvy, shhh. I won’t tell anyone.” Anna discarded her threatening posture, instead coming around to sit on the side of the bed Olivia was on, curled up with the sheet at her neck. “Why would I? You’re my best friend Liv.”
“Sorry…” Liv’s voice was a blurb, she shuddered. Anna rubbed her soothingly on the back.
“Oh don’t apologize. I told you your brother was fucking hot.” Anna said, her voice turning light. “This just kinda came outta left field for me is all. Like, fuck, you coulda warned me.”
Liv let out a nervous laugh. “Not exactly something you tell people unless you have to.” She managed to get out.
“Yeah, I get that.” Anna glanced at me, then back at Liv. “How long… ermm, how long have you guys been… not a long time… have you?”
“No no no,” Liv shook her head furiously. “Just the past few days.”
“Oh, ok.” I could tell Anna was still in shock, processing this. You and me both, I thought. “That makes it better, I guess. I understand a frustrating week by the lake.” Anna paused. “Now I know why you gave such vague answers when I asked you about what boys you wanted to fuck this summer.” Liv giggled nervously again, and Anna treated her with a smile. “And you Will, and your whole ‘no I definitely do not have a girlfriend’ routine.”
“Well I wasn’t lying…” I said weakly.
“Yeah, just leaving out a few key fucking details.” Anna shook her head again, bewildered. “Fuck!” She said again. “I just watched you guys fucking!”
“You really won’t tell anyone?” Liv asked, her voice shaking still.
“No, I won’t. Why would I want to fuck your life up? Plus, imagine the headache it would cause me,” Anna said. “What if you guys just deny it? He said she said and all that. Believe me, your secrets are safe with me.”
“Thank you.” Liv leaned forward and gave her friend a hug.
“Sorry, I uh, interrupted.” Anna added when they separated. “Just, ya know, I acted a little rashly, when I went to see if you were okay, since you’d been gone for a while, and I heard moans coming from Will’s room.”
“Knocking might have saved us from an awkward situation.” I pointed out helpfully.
“Not fucking your sister would have saved you from an awkward situation.” Anna shot back.
“Fair.”
Liv laughed. “Right? What a pig.” She finally seemed to relax.
“You’d think men’s brains start with their dick.” Anna laughed too.
“They do,” Liv assured her.
“Hey, I get you guys like making fun of me, but I’m still a bit naked over here,” I interjected. The immediate tension of Anna catching us dispelled, I was suddenly very aware of how little the sheet did to cover my nudity from my sister’s friend. And my dick was a mess.
“Well, now that’s nothing I haven’t seen before. And quite graphically in use at that.” Anna joked, but still stood up off the bed. “I assume you aren’t coming back with me Liv?”
“Not unless you want me to.”
“No, stay with your toy, just know I’m jealous.”
“And you promise? Not a word?” Liv’s voice wavered again.
“Not a word.” Anna promised. She gave us one last look, then left the room, shutting the door firmly behind her.
There was a moment of silence, then we collapsed into each other’s arms. I noticed Liv was shaking slightly.
“Door doesn’t lock, huh?” I asked her.
“I thought I locked it…” I’d meant it as a joke, but felt bad seeing Liv actually distressed over it.
“It’s my fault too, I shoulda double checked for you. Or asked about Anna.”
“I thought she was sound asleep. I didn’t think she’d wake up if I left.”
“You never know, I guess.” I whispered. Anna catching us mid orgasm kinda put us both out of the mood. If Liv had made a move, I thought I probably could’ve kept going, but she didn’t, and I wasn’t bold enough to initiate myself. It was all well and good to whisper jokes to each other about people learning we were fucking, but it was a completely different feeling actually getting caught.
“You think she really won’t tell anyone?” I asked Liv.
“I don’t know. She could. But it’s like she said, we could just deny it. It would make things awkward for everyone involved. And we were really getting along this week. We felt like friends again.”
“Thank god you put in the work you did, otherwise we might have an entirely different situation on our hands.”
Liv got really quiet. Then, in a tiny voice, “We really suck at being careful, huh?”
I laughed.

Liv talked to Anna privately in the morning, before we went back to our small cabin. I wasn’t present for it, but Liv relayed the specifics to me after. She said Anna had mostly wanted to know what our plan was. Were we just fucking? What led to it? Was it just for the week? Or something more? What about in the fall? Liv said she told Anna we didn’t really know, that it was a brand new thing, and something neither of us had really planned on happening. That we cared about each other enough to where it wasn’t just fucking, but that it was obviously complicated. She said Anna had not recanted her stance, resolute in her assurance she wouldn’t tell anyone. Mostly, according to Liv, Anna had just bemoaned the fact Liv was getting dick all week, while she was forced into celibacy.
“She asked me why she couldn’t have a hot brother to fuck.” Liv told me, once we were back and in our swimsuits, getting ready to go for a dip in our cove.
“Well, I guess it’s safe to say she isn’t disgusted by the thought of it then,” I said.
“Safe enough.” Liv agreed, shaking her head at the ridiculousness of it.
Friday was a family day. We were supposed to be on a family vacation, after all. The four of us spent the whole day together. In the morning, we did another tandem canoe adventure around the lake, our dad wanting to return them later that day. In the afternoon, we went on a longer hike. There was a nature reserve nearby, and so we spent a few hours exploring those trails. We went out to eat for dinner, there was a restaurant in town our mom had been wanting to try at some point.
Despite the assurances we’d gotten from Anna, I could tell Liv was on edge. I was a little on edge myself, half expecting our mom to get a call from Marie, or even Anna herself. The call would be short and sweet, and would change everything. I dealt with it a bit better than Liv overall. I think I was more able to accept it was out of our hands, and go on with my day whatever the future might hold. As it was, no such call came, nor any other type of tip off, and we had a great day with our parents.
We slept together wearing clothes for the first time since that first night. I was extremely horny, the whole day going by without any form of relief, but not quite horny enough to override my general anxiety. On top of that, Liv admitted she was still rattled, and not exactly keen to push our luck even more. We silently agreed to just go to sleep in each other’s arms.

Saturday, our last full day at the lake, dawned cool and clear. Checking the weather, there would be sun for most of the day, but in the evening there looked to be thunderstorms. Liv and I decided to make the most of the sunshine while we could, going for an early swim. Our parents hung back at the cabin, and there were no stray boats this early, so it was just us out in the water.
It wasn’t long before Liv was wrapping herself around me, kissing and hugging my body.
“No word from Anna this morning?” I asked her.
“Not about us. She’s planning on calling Jake and breaking the news to him. So I imagine I’ll hear how that goes.” Liv looked me up and down. “Imagine not having your dick here.”
