You wonder if you should be more actively moving your hips to her thrusts, but then, this is supposed to be about letting her be in charge. Still, the sight of her curvaceous cleavage bouncing gives you an idea. You reach up to cup your strong lover’s hard bosom, enjoying the sight of her slightly-upturned nipples pointing up at at the sky. You flick them gently as she rides you, sometimes squeezing and tugging encouragingly.
Izma moans loudly as you rub her rock hard nipples. “There’s a good bitch,” she mumbles. You bite back the retort that immediately springs to your mind; it’s all part of the fun. Still, it wouldn’t hurt to remind Izma that she’s not going to get everything her own way... your hands start to pinch and tug, mixing a bit of pain in with the shark’s pleasure, timing the hard pulls to coincide with every rise and fall of her pussy on your cock. Working those tender nubs hard, you apply all of your knowledge and skill to keeping your partner on the edge of orgasm. Sometimes, you even cup her breasts and gently caress them, but only for a moment at a time.
Izma bites her lip in response, clearly wanting to enjoy her time on top just a little bit longer. But the grunts and moans of ecstasy make it clear that the tigershark can’t hold back much longer. Her vaginal walls clamp down hard against your cock. She squeals loudly and thin streams of her girl-cum run from your belly, the wriggling cilia in her twat going at your dick like crazy. Her juices run so fast and so freely that it soaks most of your belly, narrow thighs, tight butt, and legs.
Even if you hadn’t found Izma’s impromptu cum bath a bit kinky, your cock has been just as teased and tormented - and as her inner walls grip down, her tentacles squeezing as hard as they can, it’s too much. You let out a cry of your own as you flood her interior with your spooge; you were just as eager to release as she was.
Izma squeals loudly as you cum inside her, almost having a second orgasm as her belly is bloated and distended by your inhuman amount of cum. Once you’ve finished, Izma rolls off you and continues breathing heavily. “That was amazing... my Alpha.”
You’re too busy gasping for breath to reply, at first. But then, with a smile, you pick yourself up and give her a quick kiss on the cheek. To your surprise, the ever-horny shark-girl actually blushes with delight at the gesture. The two of you leisurely dress yourselves and then go your separate ways; you back to your camp, Izma back to the stream to soak and recover.
