That's Hot...

..."road head" (giving him a blowjob in the car while he's driving)
...seeing the outline of his "goods" pushing against his jeans
...thunderstorms and/or rain (especially when sex is involved)
...watching him all sweaty and greasy while bent over the hood of his car
...when he cums so hard, he shudders all over
...when he's not afraid to use "toys" on me
...catching a whiff of his scent
