Family Ties/Close the blinds and spend some time with your son.
You fiddle idly with your bikini top's center tie, giving your lips a quick lick. Coyly, you loosen the little boy a smidge, winking at the driver, before reaching to your side and lowering the blinds abruptly. As much as you would have enjoyed giving him a show, this was a family vacation and the point of it was to spend time with family.
You finish Jacob's snack, handing him the haphazardly assembled peanut butter sandwich. He thanks you, taking a bite and going right back to his game. You sit ignored, wondering what to do. Surely there must be something you could do to bond with your oldest son. You watch him fiddle with buttons on his PSP when it dawns on you - maybe taking an interest in what he's doing will help? You lean over the table, trying to get a look at his game. "What are you playing?" you ask.
"A game," Jacob replies without even the barest glance at you.
"Obviously," you reply. You touch the top of the little device and tilt it down slightly, enough so you can see a brief glimpse of what looks like a game board with pixel characters on it. It almost reminds you of when you used to play Dungeons and Dragons several years ago, before kids, back when you used to hang out with Steven's friends. You weren't as into it as he was, but you enjoyed it quite a bit. "Some kind of role-playing game?" you ask as Jacob yanks the device from under your finger. You let out a mildly hurt huff before outright grabbing his arm and moving him so you could see the screen too, saying, "Let me see!"
Jacob gives you an annoyed glare. "Mom-" he starts as she shakes his arm free. His eyes meet yours, then dart down as his next word is cut off mid-speech. You look at him dumbly for a moment before following his gaze. The center tie on your bikini top was virtually undone, probably from all the jostling about. Your sizable breasts were a gentle breeze away from being fully exposed. Your eyes meet as you look back at each other, his cheeks tinged red. You know that look, you've seen it a hundred times before. He likes what he sees. Just like with the truck driver, you're hit with a sudden feeling of excitement. He doesn't break eye contact - the next move is yours...
