Out of the ones you've posted, I like your original image the best. However, the fonts leave a lot to be desired, especially the block outlining. It more or less comes off as "made in paint in five minutes" which isn't as big of a deal in erotica, but can still turn a lot of people off from thinking the book itself is quality.
I'm wondering how your sales are? (If you don't mind me asking.) I ask because if they're not so hot, you might try picking an image that either focuses on the sexy football player or the sexy teacher (or both, if you can find it.) The image you have says sexy fun times, but nothing about the angle. I would never guess, even from the title, that it was a sports player or a teacher, and you may lose readers skimming through covers looking for something along those lines.
