The house girls are good looking ? how many they are?
The day usually starts with 3 house girls, I'd say average looking at best. These girls tend to be on the bigger side if not straight out fatties. Mostly bulgarians. One of them has titties so huge you could easily use them as a boxing bags. Or she could easily crush water melons or coconuts (or your skull) with those, so be nice to her. I've never seen as massive tits anywhere, not even in a porno movie. Those 3 girls will usually stay there until the end.
Other house girls who are coming in later are mostly german, a bit older women, around their late 30's/early 40's, with some latinos (cuban/dominican/brazilian) thrown in occasionally. Again very average looking mostly but very wild what comes to sex. And overall pleasant to communicate with. They really seem to enjoy sex, especially those germans. Chemistry is the key here, they're not robots or working reluctantly so it greatly depends on you how your overall experience will turn out. You give a lot, you get a lot.
I've only seen one house girl I'd describe as very pretty, her stage name is Ariel and you can find her photos on Insomnia's website. She's young, slim and has very pretty face in my opinion. And she's wild, to the point of

I've also seen some other pretties there but I'm not sure if they've been house girls or civilians. And it's not polite to ask either. Nor that it matters to me anyway.
My wild guess is that there's around 5-6 house girls at the busiest and at least three at all times. Some of them only stay for few hours, some longer.
My personal favorite and most beautiful girl I've ever seen there was one persian girl with insanely pretty face. A bit chubby but I like my women like that more than skinny skeletons. I ended up fucking her almost all three hours she stayed there before she went back home to her husband and kids. I know it wasn't nice thing to do for the other thirsty guys in the house at the time (because everyone wanted to fuck her so badly, and no wonder), but we just clicked and she didn't want to fuck anyone else but me anyway. She admitted to me that she's doing some work for the house, but I'm not sure if she meant sex or some other things (not all the employees are there to provide sex) .
I've also seen one tranny there once, so keep that in mind also. I almost made a major mistake being too eager to fuck when I saw him/her on some bed in full action and I just stepped in line without having a second glance waiting for my turn to fuck that thing I thought was a girl. That tranny really looked like a good-looking female when sucking some cock on all fours and there was some skinny old grandpa pounding him/her from behind at the same time like there was no tomorrow. Maybe for him there wasn't.
I dodged the bullet 'tho before sticking it in 'cos I asked him/her if it's ok for me to fuck now (after that grandpa finally got his dirty deeds done). And that's when I heard that distinctive male voice, saying "Yes" when he/she bended slightly his/her head towards me at the same time, smiling broadly. Jesus my heart nearly stopped and my cock went limp in a nano second (he obviously has some survival instinct on his own and that's good). I excused me and went straight away to the bar desk for a beer. That beer went down quickly.
Later I saw that tranny in a shower and my dear Lord, he/she truly had a cock between the legs. But titties also (not big but anyway). I must admit 'tho that his/her face was kinda pretty, very female-like.
That tranny was very popular actually, surprisingly so. I'd say just as popular as any other girl in the house. I'm not sure if everyone who was fucking him/her even realized that they are fucking a tranny when they were banging him/her from behind. Or maybe they just didn't care. And for sure for some it was something they obviously enjoyed, maybe had been even fantasizing about, who knows? Not my cup of tea 'tho.
But at least I learned to be a bit more careful next time and at least check every single time the face and especially the crotch before jumping in action with someone there.
