Bro Darklord,

U are my idol. I have never been able to get girls to agree to take videos or even photos. Great vids by the way.

Re: Great Bonks (STRICTLY for sponsored gal only)

FR for LFT Winner

Finally managed to find time to pen this FR.

We have a WINNER. Was recommended by bro to go try their new lady WINNER. Went to location blindly without knowing looking at her pics.

Once door opened, got to see her cleavage. Very nice healthy tanned skin colour. (From certain angles she looks like the late Coco Lee(RIP)).



When she stripped got to enjoy her boobs with heavy petting but got to go shower first due to the incredibly warm humid weather.

Shower wise not much action except for the usual frenching, grinding and bbbj.

Proceed to bed with the usual catbath and started her BBBJ + DT. Sloppy style (recently alot of sloopy bbbj providers).

Got her to caps me on and action started. Would let the gifs do the FR.









Overall with current promo offered, its a very value for money bonk.

Re: Great Bonks (STRICTLY for sponsored gal only)

Galaxyxscorts💫🪐Nikko

Nikko was younger than her pics, quess the whitening makes her looks older.
Tight body with man-made boobs, scar visible under breast but overall still soft and nipples sensible.

Kiss were light, she says reserve for boyfriend.
Then comes the best, she is made for extreme hard pounding.
Missionary most of the time and at times she wanted to take control so she initiate cowgirl. She will keep asking for more and it really fire me up.
Good English so no translator needed, very pleasant session.
Definitely looking at RTF.

Re: Great Bonks (STRICTLY for sponsored gal only)

X-Factor -Minnie



[ More Info / Pictures ]
( Click to show/hide )


It has been a while since I went for a Dome 1 bonk since I have been occupied with life and travels. With much more to explore and experience across the border or globe, I haven’t really had the opportunity to try the local dishes.

Just to bump myself out of inactivity, I decided to try out a stable I have been eyeing for a long time but have not yet really tried. The OKT was nice to chat with and based on my kinks, I was recommended to try out Minnie by the OKT. Booked a slot and headed to the designated location. There were some precise steps to follow through and seems to have multiple checks. This feels like one of the more safety conscious stables for those who might be concerned. Location is also rather discreet but also very accessible by bus or car.

Entering the room, I was greeted by a lady with big cute eyes. I would say the third listing photos best depicts her but there is still a 30% discount required. I would say her features are above average, or so I thought… Anyways the rooms and shower are pretty clean and neat which is quite refreshing from the dingy budget hotels from many other bonks.

“Oh you speak Thai!” she said as she gleamed with a big smile. We conversed mostly in my broken Thai and when that failed, she understood English pretty well so communication was very smooth and it was easy to break the ice. In fact I did not open google translate throughout the entire session.

We quickly proceeded to shower and instead of 'above average', her amazing boobs bring it on another level! I then fondled them to my hearts delight. The listing said they were enhanced, but they were extremely well done, soft and jiggly. While I was distracted by her boobs, she cleaned my little brother thoroughly and then we dried ourselves up and headed for the bed.



Immediately she was licking my body, my nipples, chest, and proceeding to tease me slowly but surely. From time to time, she would make brief eye contact which definitely elevates the session. Her hands were doing some amazing work too, running them along my body throughout the foreplay. It did not take long before she started to feast on the lollipop. First the tip, licking and swirling her tongue around it. Then sucking down the whole rod, and even deep throating it. Looking at how deep my dick was in her mouth, I decided to thrust my hips a little and could hear sounds of her gag a little. Very AV like.

I decided to return the favour, kissed her lips, her neck, and slowly proceeded downwards to admire her boobs. I fondled them, shook them, squeezed them, and tickled her nipples with all my delight. Next highlight, her pussy. I rubbed my hands around it as I kissed her some more, then with her pussy becoming damp, I started to feast on it. Swirling my tongue all over her clit as she moaned and reacted to every move I made. She .. really seemed like she was enjoying it? While continuing to feast on her pussy, I started to insert my finger in. Then another, as she panted louder and louder and twitched to my finger motions. A third finger! She grabbed me hard and eventually climaxed.

With her having the time of her life, it was my turn to have some fun as well. Condoms on and she started sliding and riding me, rocking her hips and giving much pleasure. I then turned her over and fucked her in missionary with the bed creaking, boobs jiggling, and pants of her breath with every thurst. The audio and visual stimulation was too much for me to handle and I let loose my load with much delight.


Summary (out of 10):
-----
With my recent string of awesome bonks, I have been giving out 10s like it did not matter. I am trying to re-tune my rating system to make it more strict on scoring highs so you bros may have a better idea of my experience.

10 - Best in my life
7 - Amazing
5 - Average
3 - Subpar
1 - Worst in my life

As a result of this retuning, do note that more scores are going to average as a 5.

Operator Booking
  • Communication: 9 | Cordial and friendly to make the booking easygoing and inviting, yet clear and precise when needed so there is little room for confusion.
  • Location: 7 | Central location with many parking, food, bus stops, and more. Though it is in a hot area, I find it discreet.
  • Listing Picture Likeness: 7 | Good semblance, especially with the third picture.

Physical Appearances and Character
  • Personality: Friendly FWB
  • Face: 7 | Cute big eyes and friendly look
  • Boobs: 9 | Just the right size, not too big or small, with a nice shape. One of the highlights
  • Waist: 7 | Not perfect, but still a sweet hourglass figure.
  • Butt: 7 | Nice amount of flesh to grab and smack.
  • Skin: 7 | A bit of imperfections on the face, but overall smooth and youthful.
  • Pubic Hair: Trimmed/Shaven. I don’t remember seeing any hair.
  • Tattoos: About 35% coverage.

Experiences
  • Communication: 9 | With my broken Thai, no google translate was used throughout.
  • Photoshoot: A couple of pretty good pictures!
  • Sexy Clips: Does not seem keen.
  • Shower together: Helped to shower and wash me up well, some teasing and playfulness in the shower made this less commercial.
  • Handjob: Barely to warm things up.
  • BBBJ: 9 | Her tongue technique really stood out to me. The sight of her gobbling my dick is still in my head. Deep throating and gagging a little really make it feel like I was in an adult film.
  • Deep French Kissing: 8 | A Nice enough of fluid exchange and tongue swirling.
  • Fingering: 10 | Inserted three fingers and watched her squirm in pleasure! AMAZING.
  • Painting: 9 | Sensational! No foulness or odours.
  • Doggy: 9 | A nice sight to look at her curves while humping her from the back. She would naturally respond to my touch to lower herself.
  • Spoon: Did not try.
  • Cowgirl: 8 | Slid up and down my shaft in a pleasurable manner.
  • Missionary: 9 | The visual and audio stimulation was next level!
  • Audio Feedback: 9 | Sexy moans of pleasure throughout.

Overall weighted points: 8/10
Damage: $170/90/2
RTF Level: Might not be model level, but our time in the bedroom was truly amazing.
