"For fuck's sake, Julia," Samantha said when she had come back from the bathroom, "that was sooooo not cool of you! You should have warned me!"
"I'm really sorry! It was so quick, I don't know what came over me," Julia replied with her eyes averted in shame.
Samantha seemed to get even more infuriated: "Fuck you, bitch! I don't know what came over you either, but I do know what came over me: YOU! I nearly threw up from that first shot of yours and you nearly blinded me with the second one!"
"I'm really, really sorry", Julia repeated.
Samantha continued: "We started with the idea that you were going to blow me! And then I end up washing cum out of my eye and hair in the middle of the night"
Julia asked if she could make it up to her, hoping that Samantha would let her give her the blow job now.
But Samantha had something else in mind: "A blowy won't do… you'll have to let me fuck you now"
Julia's eyes lighted up. In her reality, she had only just given herself a vagina and now she would be able to get fucked by her friend. Quick-witted as she was, she played along as if she was only accepting this because she was really sorry.
They both insisted on a condom if they were going to have vaginal sex and since neither of them knew that they their anatomy was atypical, they came equipped: Julia with her ultra-magnum size preservatives and Samantha with the "small-but-mighty" type.
To them, it was not the first time for either of the two girls… except for Julia who of course had never used her new pussy. Nonetheless, sex was no issue at all: she was naturally lubed up by the prospect of being penetrated in her new cunt and Sammy's cock of small enough not to cause any pain by stretching.
Thus, Samantha was fucking her new friend's new pussy with her new micro-penis, all while being completely oblivious to the new-ness of it all.
It only took a couple of minutes until she blew her load.
They cuddled for a while until Samantha started to fall asleep.
