His kiss trailed to my neck, roaming across my skin until weakness washed over me. When his hand squeezed my breast, clarity jolted through me and I shoved him away with all my strength. "No! This is wrong!" I restrained. "My mind says the same, but why does it feel so right? Tell me why I can’t get you out of my head. Why all I can think about is f**ck*ng you!"

He kissed me hard again before his lips moved back to my neck. __________________________________ When Elyssa’s mom married wealthy Greg Almendarez, their modest life transformed into one of glitz and privilege.
