Right in the middle of sex, Shining refuses to moan, let alone let out a sound. Feeling a little insulted, Sombra decides to make things interesting by putting a bet. If Shining moans, he'll have to have sex for a whole week, no backing out. If Shining doesn't moan, Sombra has to walk around with blue balls for a whole week. Who will win (even though it's kinda obvious)? (Sorry, if this summary sucks, I hope the story is a lot better )

Warning: M/M, smut, strong language, and maybe a bit of OOC-ness!
