Match Set — Lynne Silver

Conquered Match - Book two in the Coded for Love series.
When genetically enhanced soldier Ryan Lopez learns his beloved wife Thea has betrayed his team by spilling Program secrets to the media, he takes responsibility for her punishment the only way he knows how -- seducing her until she begs for release. But the more he takes control of her body, the more he tests both their limits, and realizes he's never fully understood his wife's dark desires. It will take every bit of Ryan's enhanced strength to prove to them both that the woman he loves is also his conquered match.

False Match - Book three in the Coded for Love series.
Genetically enhanced soldier Chase Stanton has two jobs in life. One, he must kick ass on all missions for the Program, and two, breed with his DNA breed mate, whoever and wherever she may be. Two problems. Chase learns he isn't genetically enhanced after all and Doctor Samara Jones, the woman he craves beyond all reason, is likely an enemy of his team and not his true match. Too bad they can't keep their hands off each other.
