Pussy on the rag does have a smell. It shouldn't be a nasty smell though, it's just blood. Some girls don't bleed very much though, you can certainly fuck when a girl's on the rag and it isn't always too messy.
Then again, girls can have pretty heavy flows. When they get on birth control it can be a free for all. You can be fucking and all of the sudden feel something running down your leg or ass (depending on how you're banging her) and it's a visit from Aunt Flo.
The thought of it used to completely disgust me but honestly, you virgins, it's not too bad. Unless she's gushing badly, you don't need to be so childish. It happens every month so it shouldn't be anything too foreign as long as you're familiar with the vagina.
Good job, sev. You're a slut, dude lol.... she looks like a good chick to keep around for a while. Honestly, I prefer the take-home-to-mom kind of girls though. After they open up to you, they'll want to fuck you like a nympho. I don't respect a chick who'll let me fuck her right after meeting her.
