Put a thumb in her pucker

That winking brick-red sphincter is very enticing. You lick your thumb and place it at Aranta's asshole and press.

Her outcries rise an octave into a "What?!"

Then you slip inside her ass and she just screams. Her body flips out, jerking and thrashing about in a humongous orgasm that wracks her entire body. Your hand on her ass with its impaling thumb along with your other hand keeps her in just enough control to keep thrusting into her. You drill into both of her tight orifices as she flails about.

After a minute of one of the hardest climaxes you've ever caused, Aranta's spasming pussy finally pulls your cum out, and you blast her full. You come so hard, you nearly pass out. Your body jerks and thrusts as you both explode uncontrollably. You growl like a panther as you shoot deep inside the cave woman's cunt.

She slumps to the floor and you are not far behind. You both are breathing so hard, you can't speak. Your cave girl just went ballistic in a good way from your thumb up her ass. You're definitely going to do that again.

Your stroke her body as you slowly recover from such amazing fucking.

After five minutes of exhausted cuddling, a panting Aranta says, "I've never been touched there. That was incredible. Do that again sometime."
