Secretly Fucking My Brother-in-Law

It was the month-long celebration for my nephew’s first birthday. My older sister wanted to throw a big party and invited both sides of the family. I asked my classmate and close friend to come help with the flower arrangements and cake.

While we were trimming the roses, she suddenly asked:

“Hey Huyen, have you fucked your brother-in-law yet? He looks really hot. I’d definitely go for him.”

“Shhh, keep your voice down, Tam. Everything needs to be done step by step!”

“I was just asking!”

It was just casual talk, but throughout the whole party, I couldn’t stop staring at my brother-in-law, Henry. Every move he made made my heart race. When it was time for the family photo, I deliberately stood next to him. He placed his hand on my waist and pulled me closer so everyone could fit in the frame. The brief touch sent electricity through my body. My legs almost gave out.

From that day on, I found every excuse to visit my sister’s house — just to see him, to be near him… and especially to “accidentally” brush against his body when my sister wasn’t looking.

One day while I was helping wash dishes, my nephew started crying. My sister said:

“He’s probably hungry. Can you go feed him while I finish these?”

I heard my brother-in-law’s footsteps approaching, so I quickly lifted my shirt and offered my breast to the baby. When I knew he was right behind me, I turned around slightly.

“Look, brother-in-law… he’s sucking on my breast so eagerly.”

He just nodded silently and walked away.

The following Sunday, my sister asked me to watch the baby while she went to the market. After the baby fell asleep, knowing my brother-in-law would be back from coffee soon, I lay down on the bed, took off my top, and pretended to sleep while feeding the baby. I even lifted one leg and pulled my skirt up, showing off my thighs and panties.

He walked in. I held my breath and counted to twelve. He turned around and left again.

The next Sunday, I went over again. My sister said Henry had to work overtime early. Feeling bored, I said I had things to do and left.

Feeling down, I went to Tam’s house instead. When I got there, I saw my brother-in-law’s motorbike in the yard. My heart started racing. The gate was latched but not locked, so I quietly slipped inside. Before I even reached the top of the stairs, I heard Tam moaning loudly.

I knew she was getting fucked by my brother-in-law. Tam and I knew each other too well — I could tell from her moans whether she was close to cumming.

She was on all fours, ass up against the wall, getting pounded hard.

“Fuck… your cock feels so good, Henry… so deep… ah… ah… ahhh!!! Fuck me harder… I’m cumming… ahhh!!!”

Knowing he was about to cum inside her, I quietly went back downstairs and left as if I had seen nothing.

The next day at school, I confronted Tam:

“So Tam, how many times have you fucked my brother-in-law? And how did you seduce him?”

“He messaged me on Facebook first. I thought you gave him my number. He invited me for drinks and then took me straight to a motel. We’ve done it three or four times already. Yesterday my parents went back to the countryside, so I texted him early in the morning and he came over. We fucked until the afternoon.”

“Give me his Facebook account.”

“Why? But don’t tell him I gave it to you.”

“I’m going to blackmail him for a new iPhone.”

I went home, inserted a new eSIM with a fake account, and sent a friend request to “Henry Serious.” After waiting an hour with no reply, I posted a few sexy photos of myself (wearing glasses and a mask). He accepted almost immediately.

“Hi, Cold Winter Flower. What a beautiful name. I already like you. Let’s be friends.”

“It’s nothing special. My friends always tease me about it. They call me ‘Wet Pussy Flower.’”

“Haha, same here. My friends call me ‘Big Cock Lake.’”

After a few nights of flirting and teasing through messages, he bragged that his wife couldn’t satisfy him, so he sometimes looked for fun outside. I complained that my boyfriend lived far away, so I sometimes had naughty thoughts too…

Eventually, he suggested we meet in person to talk more. I pretended to think about it for a long time before agreeing, adding:

“But let’s be clear — this is just a temporary connection. You have a wife, I have a boyfriend. I don’t like jealousy or drama.”

“I understand completely. I won’t ask for anything more.”

The next evening, I showed up at the hotel wearing a wide-brimmed hat and dark sunglasses. I knocked on the door with the code he gave me. As soon as I stepped inside, I told him to turn off the lights and wait while I showered.

I quickly rinsed off, sprayed on some special perfume in all the right places, turned off the bathroom light, and walked out naked. I climbed onto the bed, took his cock out of his underwear, and started sucking it while still using a fake voice:

“Let me taste you, Mr. Henry… Your cock is so hard already… It’s been months since my boyfriend visited… my pussy is so hungry…”

He groaned as I sucked him eagerly, making loud, wet sounds to turn him on more.

His hand moved up my thigh and found my pussy. He rubbed my clit and fingered me skillfully. When his fingers found my G-spot, I couldn’t hold back and came hard on his hand.

I lifted my ass over his face. He immediately buried his tongue deep inside my pussy, licking greedily. I ground my wet pussy against his mouth while continuing to suck his cock.

Finally, I couldn’t wait any longer. I straddled him and lowered myself onto his thick cock. I rode him hard, moaning loudly. He flipped me over and fucked me from behind, pounding me relentlessly.

“Fuck me harder… Your cock is so big… I’m cumming again… ahhh!!!”

He thrust deep one final time and filled my pussy with a huge load of hot cum. As soon as he pulled out, I turned around and sucked him clean, milking every last drop.

We fucked one more round before dawn.

In the morning, I woke up first. His cock was hard again. I wanted to ride him once more, but I knew my sister was probably waiting at home, so I let him save it for her.

I went home, removed the eSIM, and went to school as if nothing happened.

On the balcony, Tam whispered:

“Hey Huyen, are you coming to Vy’s birthday party this weekend?”

“Sure, but is there anything fun?”

“I heard her brother-in-law is pretty hot too.”

“Then I definitely have to go. ‘Brother-in-law is heaven-sent. If I can’t fuck him, I’ll waste away.’”
