Hence, she undress me piece by piece without me undressing myself. We head to the shower room. She then wash me from top to bottom and dry me up after that. Good service! After our washing, she lie me down and starting working on me top to bottom without stopping.

The best hing about her bbbj is that she really uses her tongue expertly. After few minutes of bbbj, she capped my little bro and shafted into her and she started to moans softly. While working on it, she started to shower me with kisses to my face and lips. After 15 minutes, I was done with my 1st shot. I was telling myself "Oh Yeah". We then proceed to wash ourself up.

After showering we lie on the bed tcss. 2nd round she seems more relax and we started frenching. Then she says she want to be on top and work on me. She kept pulling my hands to her busty twin peaks. After 5 minutes, we change position and I'm on top bonking her. I can feel that she is very wet as the popping sound is pretty clear while I doing the bonking! It was damn shiok! After my 20 minutes of bonking, there goes my 2nd shot. Then she massage for me.

Overall. I would greatly recommend Sara for any bros who loves a great bonk with a babe with nice GFE and not forgetting her busty natural twin peaks.

Look : 9/10 very resemblance as pic 90%
Looks : 8/10 fair and not bah bah type
Boobs : 8/10 For boobs lover natural and busty
Frenching : 9/10 shoik
Shower : 7/10 action start during shower
Bbbj : 9/10 One word Good

Gfe : 9/10 For gfe lovers definitely recommended
Rtf : Yeap

Thanks Bro SD's for the fast response , patience as i was late 10 min and location was convenient and clean. She is just here so bros grab the chance fast

FR for Sara Siamdynasty

Looks: discount a bit from pic around 90% accurate, photo using slight filter, very cute girl

Body: Natural boobs C extremely nice for fondling

BBBJ: She worked on balls and gave seductive eye contact. A bit inexperienced in the way she suck, but thumbs up for her seductive innocent look

Frenching: Sensual and soft with some tongue fighting, did not initiate but very accepting yours

Fingering: I think she likes it from her expressions and moans, pussy wet easily

FJ: she was tight and is rather hardworking. Doggy was the most enjoyable due to her fantastic ass.

GFE: Very cheerful and smiley, tried to make conversation despite limited English.

Highly recommend if you prefer the innocent young girl with low mileage pussy
Thx for all
