With her ass in the air.

“Let me up,” you say, and Amber lifts up a leg and swings herself a little so you can slide out, then puts her knee back on the seat. When you tell her, “Bend over,” her face lights up with primal lust. She stands up on her knees, then bends forward and rests her elbows on the floor, propping up her torso a little. She gasps as her big tits make contact with the (comparatively) cold tile floor, but doesn’t lift up.

“Come on, baby,” she says in a voice thick with lust, “put that big fuckmonster in my tight little college-girl pussy. Go slow until I get the position right.” You stand between her legs, put your cockhead just inside her cunt, then flex your prick with your pelvic muscles. Amber looks back over her shoulder, gives you a simmering look, and hisses, “NOW!”

You grab her hips and thrust deep, claiming her cunt for your own with your shaft. You do as she says and move slowly at first while she aligns her body; then suddenly, you feel the depths of her womb open up and you bottom out in her, burying yourself to the hilt in her hot, tight sheath. You hold yourself there for a moment, and Amber moans, “Now fuck me hard, lover . . . fuck me crazy hard . . . launch me to the moon with that big fucking pussy rocket . . . make me feel it, baby . . . make me feel it hard . . .”

You make sure of your grip on her hips and start fucking Amber like a piledriver. She throws back her head; her hair spills down over her shoulders. You don’t need to grab it, because she’s already at the proper angle, and bending over that far would slow down your thrusting. You don’t want to bend over for anything, you just want to fuck her as hard and fast as you can—and she’s begging for the same thing. As you jackhammer her cunt for all you’re worth, she reaches back between her legs and starts frigging her clit. “Pound me, baby,” she pants. “Feel your balls spanking my hand . . . feel them on my clit . . . ohhh, lover, hammer my tight fucking pussy with your big fucking cock . . . so good . . . so, so good . . . so fucking deep . . .”

“You like that, baby?” you gasp back. “You like taking it like a real woman? You want to cum on my cock?”

“Ohhh, lover,” she moans, “make me cum . . . cum in my pussy, make me fucking cum . . .”

With that, you lose it. Words fail you, and you throw back your head and howl. It’s the only warning Amber gets before you grind your hips into her twat and fire blast after blast of cum deep in her hot body. She cuts loose with a howl of triumph of her own and her climax detonates around yours. Her hips buck backwards and up into yours, and you feel almost fused with her as the orgasmic storm rages through you both. It goes on and on as each of your continued spasms set the other one off again. Finally, the storm blows through with one last lightning strike, and you collapse forward, propping yourself up above Amber on your arms.

You both hold there, utterly sated, as your prick shrinks out of her, until she cums down enough to say, “You know what? This floor is cold on my tits.” You shift and roll, landing on your back on the floor, and pull her over to drape herself atop you. Both your legs are still at rest in the hot tub. You hold Amber close and lovingly stroke her back while she nuzzles your neck and traces your collarbone with her lips and tongue. Eventually, she looks at you and says, “We should probably be done for a while.”

“You’re right,” you tell her, caressing her shoulder blades. “We need to make ourselves respectable and buy some furniture this afternoon. We need a bed to sleep in tonight.”

“Ooooh,” Amber purrs, “I like the sound of that.”

“We should get beds for a couple other bedrooms, too,” you add, “so that it doesn’t look too obvious.”

“If you’re worried about my mother guessing the truth, her ego would never permit her to imagine me a rival,” Amber says scornfully. “She won’t believe it until I tell her.”

“Maybe not, but I’d rather not take the risk. We’ve agreed we want to tell her on our own terms, not let her find out for herself, so we should at least be a little careful.”

“I suppose you’re right,” she sighs. “That probably means behaving ourselves while we’re shopping, doesn’t it?”

“Sadly, yes,” you agree. “We’ll have all night to not behave ourselves.”

Amber nuzzles your ear and levers herself up. “Let’s get on with it. The sooner we go, the sooner I can have you back where I want you.”

“And where’s that?” you ask with a grin.

“Anywhere your cock fits in my pussy.”
