Breed her assertively.

You offer neither of them any greeting or explanation. Moving to stand behind the woman, you place a hand on her back, between her shoulder blades, and push her insistently to bend forward further, over the cantaloupes. Automatically, she catches herself with her hands, supporting herself against the edge of the display. You hear her let out a little gasp of surprise, but she makes no move to resist you or get out of this position. Her husband does nothing to intervene either, although his eyebrows rise a little further. "Uh, can we help you?" he asks, audibly a little taken aback.

"Oh, don't mind me," you say to him as casually as you can, amused at the idea of speaking to him while not addressing his wife at all. While holding her in place with your hand on her back, you somewhat awkwardly undo your belt and jeans with your free hand, pulling down the waistband of your underwear to let your cock spring free. "I'm just gonna breed your wife real quick."

His expression softens as understanding dawns. "Oh, I see! Fair enough."

As you turn your focus back to the woman, you find her craning her neck to look back at you, nodding encouragingly. "Yeah, actually, that's great timing," she says, a little breathlessly, as you probe between those pillowy asscheeks of hers with your fingers, searching for the string of her thong. "I've been thinking lately I want to have another baby."

Her husband looks a little surprised again. "Really? You haven't mentioned that."

Finding what you're looking for, you hook your fingers around the little strip of fabric and pull it out of the way. Figuring she gets the message about staying bent over, you take your hand off her back to grab her buttcheek and spread it, half-revealing an asshole that, from its slightly puffy look, you guess she's had plenty of practice using, and her plush pink pussy lips. She definitely doesn't look virgin-tight, but her insides look so soft and warm you could melt into them. "I wasn't sure if I really felt ssseeerious about it," she gasps as you abruptly penetrate her, driving all the way in hard. She hasn't had much time to get wet yet, but you can already feel her body responding, her walls squeezing around you as her pussy begins to juice up.

You chuckle as you begin to fuck her, taking it a little slow now that you're comfy inside her. "Well, I hope you are, 'cause I'm definitely knocking you up."

She nods. "No, of course...I want to, for sure." Her voice is still a little breathless, and her exhales come out with small sounds—pleasure, exertion, maybe both. She turns her head back to her husband. "You don't mind, right honey?"

He shakes his head, a smile touching his lips. "Not at all. I think it's a great idea."

Nice to hear that all works out. Now comes the fun part.
