Lol people getting all heated about some ambiguous possibility of any of them thinking the other was a guy, that doesn't even mean they like or not like guys, they instantly were ok with the fact of being two girls. The only weird thing is the "femininity gone cos that was for the guys" , it kinda bothered me, cos she should just be able to be as she is, for herself, not guys or girls, but that's a complete different matter.
This one shot is cute, I like how quickly they go for it and as many have noted, the "thirsty" bit really made me smile. So who cares about previousness, most people have dated other people before meeting you, I mean, unless you are super young, I am not concerned about every single person that my gf ever dated, well I do not have a gf, but I wanted to illustrate this.
I somewhat agree with the dude talking about penis being yuck but that's just me not liking that, I am not crazy for woman's parts either, but they are def more ok.
