Sneak attack??

Well, here goes nothing! You walk up behind her and grab her melons. Rebecca gasps and freezes with horror.

"No, hold on, my hands are warm!" you say loudly, but not so loud as to scare her. "Warm like a fresh Super Bacon Lord Burger from Future Burger. Damn those are tasty."

"Oh!" Rebecca gasps. Though her posture is still tense, she is already beginning to relax. "My word, you have the warmest hands I have ever felt! They're amazing!" Rebecca says. Looking over her shoulder, you see your hands barely being able to grasp all of Becky's amazing titties. Taking her lack of further anger as an invitation to move on, you slowly start beginning to massage and fondle her girls, slowly moving your hands all around them.

"Oh, oh goodness," Rebecca cooed.

"You like that Mrs. B?"

"This is most, most improper, sir. I should rightly slap you across thine face."

"But?"

"But, I must admit, your hands do feel very nice," Rebecca says with a hint of amazement. Taking that as a good sign, you start doing a few extra things. You place your hands under her breasts and lift them up.

"Wow, these girls are heavy!" you say.

"Yes, the ladies of my family have always, ooh, been blessed of figure."

"That's one way to say it," you say, as you finally pinch and pull her nipples, which have gone stiff with pleasure from your grasp.

"I think that's quite enough of that!" Rebecca says, lightly breaking free of your grasp. You let her go, and return to carrying the water home, making light conversation along the way.
