Hello. It’s been a minute, huh? Two months, according to Reddit. I’m sure most of you have forgotten my story, but I have received messages from a few people asking for an update. I started to feel bad that I wasn’t updating. I like to please, you know? I want everyone to love me, so here I am, giving you an update on where things stand with Emily.

If I were to cover every single that has happened in the last two months, well, this post would be entirely too long. So I’ll try to do a quick recap and then get to the juicy shit. After the sundress fucking two months ago, Emily and I continued to fuck at least once or twice a week. It probably would have been more if we weren’t both busy with work. This went on for a little over a month. It was a month of pure bliss.

But it ended up being the calm before the storm. A few weeks back, Emily and I were at my place. She came over after work. While she showered, I ordered some food and then we ate while watching some depressing documentary on the medical device industry. She was just wearing a pair of panties and one of my shirts. The documentary, while informative, was not exactly setting the mood. One woman was talking about how her organs were dropping out of body or something. I don’t know. It was fucked up. If I were by himself, sex would have been the last thing on my mind.

I wasn’t by myself though. Emily was snuggled up to me wearing practically nothing. While the documentary continued to play in the background, Emily casually placed her hand on the front of my jeans. She squeezed gently, which was enough to wake my cock up. She unzipped my pants and slid her hand down my boxer briefs. Emily wrapped her hand around my cock and just held it as we watched the documentary. It was an odd experience. She held her hand there for several minutes before she slowly started to stroke it. When she started to add light kisses on my neck, I said “fuck it” and turned off the TV.

We kissed passionately as she continued to stroke my dick, “Want me to suck it?” she asked seductively. “Fuck no!” I replied. Just kidding, I SAID FUCKING YES! Don’t be silly. She pulled up my shirt and planted soft kisses down my stomach, pulling my pants and boxers down as she made her journey down to the land of penis.

She dragged her tongue down the length of my cock before wrapping her thick lips around the head and sucking gently. And because she knows how much I love her ass, she lifted her hips a bit and swayed her ass from side to side. I grabbed a fistful of her hair and guided her as she kissed, licked and sucked my cock. She’s a bit of a freak when it comes to sucking cock. She loves taking it out of her mouth and slapping herself with it. I decided to do it for her this time. I grabbed my cock and slapped her cheek roughly with it. I did this a few more times before shoving my dick back inside her mouth and pushing her down on it.

“Fuck!” I moaned. I love a messy blowjob, and this was getting messy. She had spit running down her chin and water collecting in her eyes. I was reaching the point of no return, so I had to shift the pleasure to her. I grabbed her by the arms and pushed her down flat on her stomach. I moved behind her, getting a clear view of her gorgeous ass. “You’re so fucking sexy,” I told her. She stuck her ass in the air, “Yeah?” she asked.

I reached out, slid her panties down her legs and leaned forward to give her ass a quick bite before making my way down to her pussy. I slid my tongue up and down her lips, making sure to avoid direct contact with her clit for the first minute or two. I teased her wet opening with my finger, and then slid two fingers inside her pussy, “Yes, fuck me,” she moaned. I continued to fuck her with my fingers, and then quickly pulled them out to replace them with my dick, “Oh, shit!” she cried out. There was some intense passion going on this night. I slammed into her hard, her ass pounding against my body.

Every time her ass jiggled in front of me, I had to do everything in my power to keep myself from cumming. I think at one point I even closed my eyes. The sounds were enough for me. Her moans, my moans, the slapping of skin…it was a full on symphOH-HONEY.

And then the knock at the door. We didn’t hear it at first, but then it got louder. I thought maybe it was one of my neighbors complaining about the noise, “Can’t they wait until it’s over, at least?” I thought in my head. I put on my boxers real quick, which was quite a challenge for obvious reasons. Emily covered up with the blankets and then I went to the door. I don’t know why I didn’t look before opening. Actually, I do. My mind was still on fucking. I wasn’t thinking about anything else.

I opened the door slightly, “Dude, what the fuck is going on in there?,” my dick got instantly soft when I heard his voice. It was Daniel. He pushed his way inside, clearly a bit drunk. Emily tried to turn around, but it was too late. He saw her.

“Emily?” he stood by the door. I stood next to him, still in just my boxer briefs. He looked at me, “You’re fucking my sister?” he asked. I could tell he was pretty upset by the tone in his voice.

“I think we should probably talk about this when you’re sober,” I suggested.

“Fuck off. I’m not that drunk. How long have you been fucking my sister?”

“Okay, you don’t have to keep saying it,” I told him, before adding, “Not long. A month or two.”

“TWO MONTHS?” He yelled.

“Daniel, calm down. It’s not a big deal,” Emily said calmly, still hiding under the blankets, “It’s not anything serious.”

“Oh, okay. So you’re just fuck buddies? That makes it better,” he said sarcastically.

This went on for around five more minutes. Just back and forth nonsense before he left to go catch another Lyft. Things have been extremely awkward ever since between everyone. Daniel isn’t as pissed anymore, but he’s still not happy that we didn’t tell him. I’m not sure our friendship will ever be the same. Emily and I are still talking, but we haven’t really seen each other since. Not because she feels bad or anything. It’s just all a bit different now. Hard to explain.

Anyway, that’s where everything is at now. UPDATE COMPLETE! Sorry it’s not a happy ending.
