Back to topic....
My gf's block is linked to a mscp. 1 day by chance we found a nice ulu spot at 1 of the mscp staircase. So sometimes we will go there (higher floors) to smoke and bonk. It is well hidden but people walking pass on the first floor at certain angle (partially blocked) should be able to see us. It is quite exciting to bonk there as you never know if someone will walk pass on the first floor and look up or the staircase door will open. The staircase is very bright so if someone looked up will confirm see us clearly.
As it is very near her house, so usually my gf will not bother to change and go to the staircase with me. Usually will be in her sleeping attire.
Bonk her completely naked a few times there.
