I [20][M] fucked my gf’s best friend [18][F] while we were on a break and had the kinkiest sex I’ve ever had. (I got introduced to consensual knife-play)

Go to paragraph 5 to start where it begins to get good if you want to skip intro stuff.

Go to paragraph 7 to start where it is actually starting to happen. Paragraph 1 begins below.

This is a long one. It’s my juiciest story and really my only good one but I swear everything in here is the truth or the closest to it that I can remember. Theres enough in it to end my current relationship but I’m confident she won’t find it. I’ve switched the names and stuff to help with that.

This all started in october 2020. My gf [20] and I [20] had been fighting for months. She hadn’t been in to having sex with me for about the same amount of time. By the time october came around I was already in the middle of a 2 month dry spell. And then we broke up, she said that she thought she wanted us to get back together later at some point so I guess it was a break? After receiving a few harsh words from her via text when I was just trying to be nice I thought it was OVER over. Depressed, I turned to some of my friends for help. Anything to distract me. They were all girls (I only end up with one of them), we’ll call them R, J, and C. They also all were connected to my ex in some way. R was mutually good friends with the both of us, she was the one I thought I was going to hook up with. J dated my ex and hated her guts. And C was really close to her since they had classes and extracurriculars together in high school.

We started hanging out a lot and they came over to my house on a weekly basis. But one night when R and J had to go home early C wasn’t ready. She was living with her parents at the time and she has a rocky relationship with them at best. She had an 11:00 curfew and she was going to stay out all the way until then. Being cold and wet from the rain I tossed her hoodie in the dryer and invited her into my bed to get warm. C is a cute girl. 5″1 Asian a little bit on the plus side. Long, curly hair, bleached a few inches away from her head and dyed a bit red looking like polished copper. But the most defining feature about her, sexually, was the fact that her tits were huge. G cups. The kind where she had to get bras and bikinis custom made and she was supposed to be getting a reduction surgery soon.

It was that night that we hit it off. She’s very bubbly, very funny and we just kind of clicked in every way. Ideas, wants, music taste (music was a big thing for all of us) etc. And it became apparent that this girl was horny. REALLY horny. R and J apparently knew about this very well and being the lesbo that J is, frequently invited C for 3-somes. C always declined being not attracted to women. Eventually it got to the point that we agreed to a FWB relationship. It would be a couple weeks before anything happened though.

C ended up coming over by herself rather often just to hang out and it quickly became exposed that she liked some kinky shit. Yeah the tie me down and choke me stuff, been there done that. But there was this one thing that I had never heard of that just turned her to mush. Knives. She had a hardcore knife-play kink that I had never heard of before. She had told me that it was her dream to be fucked hard and rough while having a sharp blade or even a gun pointed at her. This absolutely blew my mind. I’ve seen a lot of porn and a lot of kinky shit but never had I ever heard of this. She had had a few partners before but none of whomever indulged her so. I’d never played such an intense dom before so I was down for the experience. Every once in a while I’d tease her with it. In car rides, just hanging out, sometimes even with our friends (they didn’t know about it). I have a spring assisted pocket knife, about a 4 inch blade (what’s legal to carry publicly in my state) and VERY sharp. Actuslly, my ex had bought it for me as a special gift since she knew I’d been wanting one for so long. But there was something about pulling the knife out and holding the point to her neck or her breasts that she couldn’t stand against.

After this had started happening she started calling me by dom titles. Weird, but welcome. Sir, master, and weirdest of all to me, daddy. Being young that I am it was weird to hear but given the situation I had fun with it. She began sending me nudes over instagram and snap and doing as I commanded. Only cumming when I allowed. Taking pics as I asked. She even tasted herself for the first time. It was at this point that I started “training” her. Taking inspiration from the good awful 50 shades of grey that my ex had made me watch, we started a routine. I’d tell her to “get into starting position” to which, she would strip and get on her knees with her hands on her thighs. Mouth open and tongue out was the bit of flair I added because I thought it was hot. I told her that this is how she would greet me at the start of a night of sexting and nudes and is how we would start for our first time.

Fast forward a couple more weeks of me teasing her and making her wait, we went out for a day of driving around the state, taking pictures, talking and listening to music. She had also stopped masturbating for a the time being to make the first time a fun one for her. When we got back to my place it was like 9pm. I was tired after such a long but great day with this amazing girl. We were in my bed together just talking about the fun day we had and some crazy philosophy stuff, the universe, whatever. I forget exactly how it came up, but at around 10pm the conversation moved on to sex and our kinks and stuff. “Oh you mean like this” I said as I pulled the knife out which we agreed to name after her. Pointing it at her she didn’t show the same excitement as she did before. Still obviously getting turned on by it but much less excited to get going and more so disappointed to be having the blade at her knowing she wasn’t getting any dick like it had been for the past couple weeks. “What? You know that doesn’t really affect me anymore” she said “you’re never going to do it.” Taking this as a personal challenge and playing to the dom character of our relationship, I decided I had to punish her. “Oh really? Get into starting position.”

C: “What, no… really?” “You’re joking, right?”
Me: “Nope. Now. Get on your knees.”
C: “But why?”
M: “Because you challenged me. You disrespected me and I can’t stand for that. Because of it, you have to be punished. Go get on your knees by the bottom of the bed”

To which she rolled off the bed pulled her arms into her shirt and took it off. Looking back at me nervously but excited as I sat up. She got on her knees by the bottom of the bed.

M: “uh-uh, all of your clothes come off.”
C: “Do I really have to?” Becoming really embarrassed by now.
M: “Yeah, you’re being punished for being a bad girl, now take it off.”
C: “Yes daddy.”

To this she took off the rest of her clothes and sat back down on her knees in the middle of the floor.

M: “I told you that if you were going to be a bad girl you were going to wait like that for me in here while I watch. You’re lucky I don’t have much work to do, otherwise I’d leave you in here alone like that while I did it. Maybe I should go clean the house? As punishment, just leave you in here while I go do other things. Should I do that?”
C: “Please, no.”
M: “Please no, what?”
C: “Please don’t daddy.”
M: “Okay, just because this is your first slip up, I’ll be a little nice. But next time I won’t give you such niceties. Understood?”
C: “Yes daddy, thank you.”
M: “You’re welcome.”

Being not the most patient man and having a cute naked girl in the middle of my bedroom floor, I was only able to hold out for a few minutes before I started to play with her. I grabbed my knife back from the nightstand and walked over to her. I squatted down behind her, put my arms around her and opened my knife backwards at her neck. I did this as not to actually cut her but knowing that she couldn’t see it, thinking that there was more real danger involved would drive her wild. I began holding the tip of the blade to her skin. She shivered. I began walking around her, running the tip of the knife backwards across her back, chest, stomach, and those huge tits (she says they’re 5lbs each btw). Even trying to be light and using the opposite side of the blade, this still left red lines across her skin. She could not have been happier. At points shaking uncontrollably. I didn’t even finger her but she said afterwards that she came twice from that alone.

Getting to be more like 10:20 now it was my turn. After weeks of her hyping up her head game, I was finally ready to see it. Undressing my lower half and sitting on the edge of my bed I told her to suck me off. She struggled with it a lot, which was kind of disappointing since I am a big fan of blowjobs. She said it was bigger than she was used to, not being able to fit the whole thing in her mouth. I am exceedingly average in size. In between 5-6 inches so I don’t know if she’s just saying that or if that’s saying something about her past guys. Most of them were Asian to my knowledge so that could explain it.

That didn’t matter too much to me though. I also LOVE giving head and had also been hyping up my game. I told her to get onto the bed and spread her legs for me. A fresh shave and an outie. I grabbed her knees and pushed them further back to her chest and went down. More uncontrollable shaking. But this time I could punish it. Going harder and faster until I could hear her having trouble breathing. I could tell she came at least 4 more times there.

My face soaked and sticky I got up and grabbed a condom. I was worried for this next part since the last few times I had had sex with my ex, it ended very quickly. I didn’t want it to end like that. I checked the clock, part put of insecurity, part to make sure I would get her home on time (she lived nearby but still heard that 11pm curfew).

I put it in. She moaned loud as she had been when I was eating her out. My mom was sleeping upstairs and my brother in the room next to us. I still live with them to help her out watching my brothers and because I’m going to the local college and it’s the most cost-effective. “You’re going to have to be much quieter than that or I’m going to have to shut you up” I said. “Yes daddy.” She replied but she still couldn’t control it. I grabbed a pillow and shoved it into her face as I pounded her. Her moans still could be heard, muffled through the pillow. I took the pillow off and she gasped for air. I flipped her onto her side, pulled her top leg up and fucked her there. This time pulling her hair and shoving her into the pillows. Much quieter. Over the next 15 minutes I flipped her into the other side, doggy, and back to missionary with her legs high up on my shoulders (she was flexible from doing tahitian dance). I hadn’t lasted this long in forever.

I thought I was about ready to finish so I pulled out. Took the condom off and tossed it onto the floor.
M: “Get on top of me”
C: “Like how?”
M: “69”
C: “Okay”

I ate her out some more, being crushed by large soft thighs and being sucked at the same time. This angle was much easier for her. I slid all the way in and back out. She took it into her throat at times and without gagging. I grabbed her head and fucked her face like this for 5 minutes but I had lost it. I grabbed another condom and fucked her pussy for a second round. I had been keeping track of the time, and if you have been too, it was getting late. I didn’t want to leave this without finishing. I pumped harder, and faster this time. Her legs shaking vigorously by now with no hope of being stopped.

After a while we went back to 69 and I tossed the second condom next to the first. I’m going to have to clean the whole bedroom later, I thought. I started off eating her pussy but got distracted fucking her face and throat almost abusively. I needed to get her home. And I needed to finish. I don’t know why but I just wasn’t feeling it tonight. I started going through the highlight reel. Best porn I’ve ever watched. Mia Khalifa. Mila Azul. Ava. Throatfuck. Bdsm. Even my ex for a bit. Eventually I got there. Returning to reality, pounding this chick’s face with her pussy in mine. I whispered in between breaths “I’m gonna cum.” And a few moments later I blasted a huge load down her throat. She swallowed all of it. What was left over on me she quickly cleaned up. After that she came up to kiss me. Not wanting to taste myself (I’m not homophobic or anything, just really averted to that stuff for me personally) I made sure to keep it quick. She wanted tongue action but I was closed. She got the hint pretty quick thankfully. It was already 11, past her curfew. Hopefully her parents were asleep (which they usually are when she gets home, it’s just a bad time when they happen not to be). Half an hour. That had to be a new personal best for me.

Getting off the bed, it was soaked. I was definitely going to have to wash the sheets the next day. Easily seeing the silhouette of her back and ass and a bit of mine too. Her face was red, hair everywhere. She looked exhausted yet very satisfied. He legs were weak and shaky and she was covered in sweat. She even still had red lines across her chest and back from the knife play earlier. We quickly shuffled into the car to take her home. I apologized for the scratches to which she blew it off. She told me she absolutely loved it. And in the end, I shit you not, she said she came at least 12 times. I dropped her off home without incident.

This ended up being the only time we hooked up because my ex and I ended up getting back together. After telling her that C and I hooked up, we weren’t really allowed to be friends anymore. Not because she told me not to, but because out of respect for her feelings and knowing how I’d feel if the roles were reversed.
