My previous FR:
https://sammyboyforum.org.nz/showthrea...=#post21483415

Mission executed on 2 Aug. Not sure if she's shifted since but the location then was a private apartment somewhere south near major MRT construction. Spacious room and toilet. Clean towels. Appears to be very safe and apparently no security. Driving shouldn't be an issue. However, for foot soldiers do check the map very carefully. 15min walk from bus stop. MRT construction can block up foot access. Took the wrong path and had to double back.

Second visit and service level still there. Continuous frenching and she enjoys hard banging. New info: told me she's waxed, no wonder so clean and smooth down under. Maybe due to location support seems relatively sparse. Took some pics at her request to put up here. Hopefully helps her to get busy.


Linda has a nice butt...




and she's hard working




Edit: Can anyone see my pics above? Hosting from SBF album. Or anywhere else can I upload and embed here?


Well, can't go wrong if you are looking for good service and not inexperienced SYTs or big b00bs.

End of FR.

8/8/22 tarma moji and nova



Moji
Looks 10/10 25 fair slim juicy
Boobs 100/10 big natural juicy tits
Bbbj 10/10 sucks hard tries to dt
Cim 10/10 suck everything in, no drop wasted
Fj 9/10 doggie and missionary tits flying all over

Nova
Looks 10/10 face more matured but body fucking tight slim fair sexy
Boobs 100/10 big perky soft firm round tits
Bbbj 10/10 soft gentle and tries to dt
Cim 10/10 full first load all in does not shy away and takes like a champ
Fj 9/10 on top riding and missionary

Both girls are friends and work very well together had either one on my nipple and one on my dick or my balls, when I open the door both ladies opened the door with sexy night cloths and immediately I laughed to myself cause the last time I had two was a while, moji showered me and when to the bed, both started stripping and I was in boobs heaven, both of them had very beautiful tits and towards the end I found out that it was both real. M was bigger and my juicy and n was more round and perky, both were big and soft and my hands was on their both their tits the whole time. N started sucking first and she was more gentle kind of sucking and she started gagging me and i almost cim like in 5 mins, I stoped her and ask m to suck me and m was more of a hard sucking type and I stopped her again, because I was going to cum. I told m to suck my balls and n to cim, immediately, I nuted while squeezing both tits and told n to speed up, no cum wasted, all unloaded, and as n washed up, I was playing with m tits, I wasted no time, I requested m to start sucking me and she did it so well, the whole time writing, I am asking who is better in terms of tits and bbbj, but both is good. M sucks harder while n is more gentle. Both tits are fucking awesome, m is juicier and n is more perky. While m was sucking me n open d the door and immediately when for my nipples, requested to cap on but they misunderstood me and n started sucking me while m was on my nipple, requested cap on and fucked slim n quickly before changing cap and trying out m, both tits flying everywhere when fucking, a good ten mins each and than unloaded onto m to see if she was better to than n but both where equally good as they took everything in like champs and speed up whilst cim.

My plan was to rtf the better one but I guess I have to rtf both lol. Cim and tits lovers will love them. If there is a difference, m has bigger tits and sucks harder while n has perky round tits and sucks gentle, both cim no issue and works together very well.

Review for min from Galaxyxscorts

Took her before before covid time and had a great time

Text bro Okt and took her yesterday

Location area G

Knock on the door and there she is.. This time she looks better then previous and I was surprised that she remembered me too

Took me into shower and I fast grab her big jugs and played it well.. Fingered her and she moan loud saying she can't tahan already

Went to the bed and she started sucking my hard dick.. I push her head deeper and she can really take it well.. Continuing fucking her mouth and I told her I wsnt to stand up fucking her mouth.. This time I fucked her mouth deeper and faster and deposit all in her mouth.. Damn good

2nd shot started after chit chat awhile with her and she told me covid period she can't go oversea so only can do some online business.. Ya..hard times for alot gals and she told me is really not easy to sell things online too as too many ppl selling in Thai..

Fucked her missionary at first and she ask me fuck her doggy as she loves to be bang behind and smack her ass.. The harder I smack.. The more horny she gets.. Fuck this slutty bitch..

Cum hard together after I think she climax a few times before me.. Lol

FR for June LA

OKT was very responsive, friendly and accommodating to last minute request, thanks for setting it up!

June was gorgeous, top-notch looks-wise. Very cute vibes.
Great service, wouldn't let me shower myself haha.
Great chit chat, amazing GFE. Lots of hugging and decent english.
Initiative in BBBJ and changing positions, felt like she was really into it, no budget fake moaning here.

She's a great girl looking to earn while providing great service with no time-watching.
Please treat her well bros.

Re: Great Bonks (STRICTLY for sponsored gal only)

Booked summer from Poison early this week
Been to his stable several times already. Great guy.
Upon entering the room, was greeted with smile and she said she kept saying she’ll take good care of me. Lady with braces, enhance boobs, very nice ass, about 1.55m tall, great figure. Was told to shower together. Showering was great with lots of rubbing against each other. Once done, she wiped me which is quite rare to have this kind of service, continue saying she’ll take care of me.

No BJ from her as wanted to jump into action. Oh ya forgot, she asked for my name initially which she moans to my name. Didn’t really french her though so no comment. Ended up cumming on her beautiful ass while doggy. Great girl who provides great service.

Re: Great Bonks (STRICTLY for sponsored gal only)

Jenny from Empire 1 week ago.
2nd time picking girls from him (first time was Money, will include review of her in same post)

Entered the room and the lady is quite petite, around 150cm or so. Huge breast, natural and sagging. She was very friendly and smiley throughout our encounter. Told me to go shower, no shower together as bathtub too small so she stood outside the bathtub to shower me. When done showering, she covered me with a towel and gave me a wipe, switched off the aircon for a while.

Told her to take off her bra which can sense she’s quite shy as she kept hugging her boobs with both arms. She’s shy but in a good way. Got her comfortable and we start FJ. I would say is one of the best experience I had (aside from Minnie from Poison and Milk from LA, both left liao. I think I didn’t write review for Milk cuz she’s a gem + no incentive from stable Haha). Anyways, sex was very intense and she’s open to rough fucking, say I can do anything to her which was a turn on. French was excellent! Ended up cumming in missionary on her stomach.

Sexy right? https://ibb.co/p3jDhcR


Money from Empire
Honestly was a bit lower than expectation. Maybe I read review and people saying how great she was so my expectation was higher.

One thing for sure is she looks extremely good. Looks mixed but she said her parents are both Thai, even grandparents (dunno true or not as she’s talk cock a lot, very friendly girl). Her height is about 160cm. When I entered the room, she was in a dress, damn turned on by looking at her. Told me to go shower and she came in which we showered together. Her boobs are enhanced big C, tight body. By then my cock hard already, told her to quickly get it done with so we can move to the bed. Oh ya, she damn slutty lol, the way she kept teasing me with her ass and ‘the look’. Gave me a bbj and was great (not as good as Opal from Mansion, review next). But gosh she’s a sight to look at when she eyed me while giving me a BJ. Felt a bit of teeth though. Then capped me and rode me. Her pussy was very tight, like super tight for me. Wasn’t a cowgirl type so I changed to missionary. She was very flexible, crossing her leg while I fucked her. As usual, changed to doggy and cummed. After that we chitchat for about 15mins. Great girl but service wise won’t return. More of a 1 time fuck girl.

Look how sexy she is : https://ibb.co/tp3bLGw

Re: Great Bonks (STRICTLY for sponsored gal only)

Opal from mansion (31/7/2022) she went back on 3rd August.
Been eyeing for quite some time before taking the plunge. Read reviews upon reviews and told myself have to try especially when she looks a bit mixed with great body. First time booking from Mansion and it went smoothly. Had to wait outside the hotel for directions though but not much hassle then she picked me up to the room.

Entered the room and say heels (I think around 4 pairs) neatly laid on the floor. I’m a heel guy so immediately turned on Liao. I knew which heel for her to wear when I entered and my dick got hard immediately. We broke the ice and talked a bit which was first time. Normally girl just gets into shower and action. Probably cuz she’s quite comfortable in English so not shy to speak more but can see she’s a very confident girl.

I think I saw review saying shower together but was told to shower alone as the shower quite small, so she waited outside. Err immediately think maybe no chemistry as Ang moh is more of her type. But honestly, was expecting it as I’m a lot younger but just went for it as I went in to fuck a gorgeous lady with good body so like once in a lifetime thing lah.

Told her to wear heels she was weirded out by it cuz maybe first time + she said it’s gonna make the bed dirty. But was quite happy she obliged lah. After wearing she asked what to do then told her to suck my cock. Omg, like wth, got training this girl. Her sucking skills is the best, sloppy with lots of saliva and I didn’t feel her teeth. Was very into it and pushed her deeper then immediately got told off (that’s why I say a bit of confident this lady haha). Said it’s painful and imagine if she stuck a dildo in my mouth LOL. Apologise and all is good.

For FJ with french, I would say is top (but that’s because she looks hella good). Lips are thick as well. She’s very into frenching. I usually try to last at least 30mins - 45mins to get my money worth lah. But cut short as she said she wants to pee, told her she can go pee first then we continue but then she said she will pee after. Ok loh, continue fucking but like, her looks is top tier so cannot stand and ended up cumming.

We then talked while she eat, even offered me to eat LOL. I think she started opening up more and getting a bit comfortable with me but sad I didn’t get the chance to RTF as need to recharge. Then I cheekily said ‘sad I didn’t get to see her ass’ which she replied ‘visit me next time’. But damn, never got a chance to doggy her. Will I return next time? Hell ya.

So far I think that’s it from me for now. There’s quite a few more girls I saw but didn’t review cuz all went home Liao + not the greatest sex/too good to share. Bye for now, trying to cut down on bonking haha

Edit: is actually 4 heels haha https://ibb.co/9GSvBnx Of course I picked the highest black heel. Damn hot man with pretty girls in heel
Also mods IDK if can link to other website. If not happy just ban or downvote me lor, IDC haha. Honest review also downvote then complain of all the fake reviews you guys are having here. Ded
