Mine for the Night — Brenna Lyons

In a future where an interstellar foe has infected humans with a virus that destroys males entering puberty, the only way to save the human race involves a bold plan. Males are kept on hormone suppression, until they reach 25 years of age and their bodies have outlived the virus they are born with. With hundreds of viable women to each maturing male, carefully selected pods of four women to each man are assigned. But before those men take their place in their pods, they belong to the female scientists who made the suppression possible...for one night of completely uninhibited sex.
