A Wicked Treat by Crimson Syn (Sinful Holiday Series #1)

Summary by Goodreads:
A WICKEDLY SWEET HALLOWEEN ROMANCE

Anthony Reed has me primed and ready for so much more.
More of his mouth, more of his touch, more of his deliciously dirty words.
The man seduced me from the first moment I saw him,
And I can’t seem to stop myself from getting lost in him.
But my job is at stake, and so is my heart.
Yet I can’t help but fall for his devilish ways.

I have never yearned for a woman like I do Miss Ana Collins.
She’s beautiful, smart and unbelievably tempting.
She’s also my daughter’s Kindergarten teacher.
I should stay away from her, protect her, but I can’t do that.
My angel means everything to me.
Even if I have to fight my torrid past, I will have her.
She’s the only one who can mend my broken heart.

His Indecent Training By Sky Corgan

Summary By Goodreads: 
There was an uneasy feeling in my chest as I stared down at the submissive questionnaire Damien Reed had given me. For the past few weeks, he had been teaching me about sexual nature and fantasy. This would be taking things a step further. Learning about BDSM would put our relationship on a completely different level—a level I had wanted so badly since first setting eyes on Damien Reed.
