The Zoo/Don't let him cum
From Create Your Own Story
You wrap one hand around the base of his cock and furry ballsack, squeezing him like a cockring. He moans, his hips jerking as you ravage his tight passage with your tongue, licking over his sweet spot until he's begging and pleading.
"Oh! Oh, please let me cum!" he cries. You plunder his quivering hole for another minute, then draw back, the musky taste of otter on your tongue.
"Do you want to cum with my cock in your ass?" you ask.
"Yes! Yes, please," he mewls.
