Mmmmm, exciting and hot and so IC! I love their bickering and that they needed to find out who's the biggest wanker... so typical! I also love the little hints that Severus lost on purpose - it would be Slytherin-esque behaviour, wouldn't it, to lose the game so that you can do what you like? Hehe. (Also, lots of love for Severus loving to suck cock! :D) Wonderful story, really!
Wonderful story, really!
