You've been watching the hunk next door with the big package since he's moved in. He started digging up the ground shortly after he arrived, and you assumed it was for a pool, but then a building went up. He's so hot you're intimidated around him and can't do more than nod and say hi when you see him. You finally muster up the courage to ask him what he's been building, and he smiles broadly and says, "Pool house, with underground, heated pool. I need the water, and winter's coming." You try not to, but your eyes drop to the bulge in his crotch, and when you look back up, you see that he's seen. He's smirking. "It's almost finished," he says, and his grin grows. "Should be done by the end of the week if ya want to help me christen it." You say sure, but figure he'll forget. You're sure he's forgotten you the moment he turns away. But Saturday afternoon your doorbell rings, and when you open it, there's a towel on your stoop with a note that says, "she's all ready. Join me when you can." You change into your trunks so fast you nearly get tangled in them. Then you're at the pool house and see another note taped to the door. "Come on in. I'll be there in a few." You race into the pool house and down the stairs. It's a stunning set up, with a sauna and showers. Real classy. You strip to your trunks and head into the water, which is a perfect temperature. Then you hear a door open and turn. It's the door to the sauna, and your neighbor is walking out of it, buck naked, huge hardon, and a shit eating grin. "Pretty nice, eh Joe," he says, and you wonder when you told him your name. you must have. He walks toward the edge of the pool, but as soon as his foot hits the water, he starts to change, his skin changes color and scales appear, and fins, and soon enough he's standing before you, this shark thing, and you realize why that grin always seemed so predatory. Mostly, you realize his junk has gotten even larger. "What's a matter Joe?" it asks. "Eyes bigger than your stomach? You know you want it." And the thing is, you do. And he gives it to you. Over and over. And by the time the afternoon has ebbed into evening, you no longer care that your neighbor is an alien. You're just hoping he's going to invite you over again real soon.
