Rachel's Gratitude (pic)

Rachel turns her head towards you. It takes her a moment to spot you, and when she does she's looking at your swollen cockhead that just spurted a geyser of cum all over her back.

"Did you just fucking cum all over my back, David? YOU ARE THE WORST FUCKING BROTHER!"

"Aren't you going to thank me, Rachel?"

"THANK YOU? I WILL **** YOU!"

Your younger sister jumps up from the lounger and pushes past you. She's topless in just a tiny bikini bottom. At five feet, she comes up to your chest. She looks adorable raging.

"No man jizz in my lesbian moms' hot tub. Take a shower first," Kate calls out, but it's no use. Rachel storms past you and takes a running jump into the hot tub. After surfacing, she sits and sulks with the back of her head to you and the cum cream peeling off her skin.

You walk up and rest your hefty shaft on the side of the hot tub next to Rachel. "Don't you want to give my dick a nice thank you kiss, Rae-Rae?"

She shakes her head, avoiding looking at you.

You poke her dimpled cheek with your meat. "My dick likes you, Rae-Rae. Why don't you like it back like a nice sister would?"

She shakes her head again and flashes a middle finger.

You rub your cock head on her cheek. "Look how much precum you're making me spill. If you don't suck my dick I might jizz all over Kate's lesbian hot tub. Don't you care about Kate's lesbian moms?"

Rachel rolls her eyes but opens her mouth. Somehow whatever the third thing you say has a way of convincing **** sluts to open their mouth in the Blowjob Universe. You swing you leg over and straddle your sister's face in the hot tub. She carefully laps and suckles at the precum forming on the tip of your man meat, but of course that's never going to be enough. Your balls are working overtime, and Rachel's going to have to keep her perky mouth up.

You thrust into her mouth, massaging your cock against the firmness of your sister's palate. Fury flashes in her eyes, but she has **** but to be a good sister in the moment. Her hair is wet from her dive, perfect for wrapping around your hand. You make her bob her pert mouth on your dick until you need more, and then you stretch her throat like nature intended.

Rachel looks more beautiful than ever with glistening water droplets dripping from her hair and your enormous cock distending her throat. She gags as you keep her in place and fuck her tight throathole. *gack gack gack gack* She's the perfect throatdoll to sate your dick's need for tightness.

"Guhh," she makes barely audible, incoherent noises around your cock.

*gack gack gack* You pummel her facepussy with your meat rocket, until at last you feed her a late lunch of your cum. She swallows it all like a good sister to you and a good friend to Kate, not spilling a drop in the hot tub. You keep the cock deep inside for a thorough polish, until at last it emerges spotless from Rachel's drooling, messy face.

While you were busy messing up Rachel's complexion, Kate has cleansed hers. The face mask is off and her skin is gleaming. She stands up stretches before speaking. "Girls, I'm feeling so relaxed. How about a second margarita before we play Truth and Dare?"
