Amy's asshole

You cram your cock down Amy's young gullet a couple more times before pulling out. Her messy face is covered in saliva and precum.
Rachel looks at the two of you before turning away again with a very loud "Ugh!"

Amy just giggles as you position yourself on top of her and pull down her yellow bikini bottoms.
"Alright babe, I'm just gonna start with your asshole."
"Ok," Amy softly says, and she reaches back with her hands and spreads her cheeks for you. You take a look at her tiny, brown asshole, spitting in it before sinking your well lubricated cock deep inside of it. Amy moans, and you two start passionately fucking away. She stops spreading her cheeks now that you're already inside of her, propping herself up on her hands so that she can arch back and look at you. You intensely gaze back at her as you fuck her ass.

PLAP! PLAP! PLAP! PLAP! PLAP!
The noise from clapping Amy's cheeks attracts the attention of some blonde surfer girls, and a couple of bikini-clad MILFs. Some look your way, but all of them treat it as socially acceptable in public. That's because in the Blowjob Universe, it is.

Soon enough, Amy is brought to orgasm. You grab her exposed tits as an orgasm washes over her. Her legs shake and shudder, and she stifles screams of pleasure. You're focused on Amy, so you don't notice that Rachel is trying to hide that she's touching herself under her bikini.

You and Amy share a kiss before Amy gets out from underneath you. "My turn," she says, pushing you onto your back.
