Night Latch by Alex Blaine

Preston has almost everything money can buy. The cars. The mansion chalet in Aspen. The CEO salary. And an entourage of fake people surrounding him that come with running a billion-dollar software company. But what he values most is hard to come by. Privacy. Comfort. A warm body to fall asleep to. His last partner got him used to a night latch, but since their break-up, Preston hasn’t had a good night’s sleep, and it’s starting to affect his ability to function. With sufficient NDAs and anonymity, maybe he can pay for the nighttime company he’s so desperate for.
Otto is a member of The Lactin Brotherhood and has been to a few conferences, but there isn’t an active chapter in the resort community he lives in, so he pumps and dumps and doesn’t give a whole lot of thought to his milk. His job as a private driver pays the bills and keeps him busy, but the distance between him and his clients means he never makes any real connections.
When an unexpected request from The Lactin Brotherhood comes into his agency, Otto is the only man on staff who is capable of fulfilling the job. A rich guy wants to fall asleep on skin. Simple enough. At least until those pesky feels get in the way.
