once i did it with my ex gf at sentosa, there is two towers that you need to walk across the hanging bridge, totally naked and doggy her at the top of the tower under the moonlight and cim. shiokk....
same gf, happens around 10+pm weekdays, we were so horny and hands all over each other that we had a quicky at the outside parameters of suntec tower (dunno tower what) beside the ECP entrance to suntec city. standing with one of her leg up and came within minutes... she did not even put her panties after finish and the mixture of her juice and my cum drips down as she walks. catch a cab and continue to keep my finger inside her pussy....
these are the most memorable outdoor fucks..
thinking back gives me the hardon...
