Sara.

"Me!" Sara yells before the other girls could answer.

"Aw!" Lisa whines.

"Don't worry, Lisa," Sara smirks as she unbuttons her blouse, "Mark has the stamina to endure the thanks from all four of us!"

She takes your hand to lead you to the armchair and pushes you down to sit on it. She unhooks her bra when she turns around to grab a throw pillow from the couch. Your already hard cock gets even harder when she tosses both her bra and pillow at your feet before kneeling in front of you, offering you great view of her ample tits.

"I see you're ready to be thanked," she giggles after unzipping your pants and freeing your erection.

"Yeah..." you mutter as she grabs your shaft with one hand and cups your balls with he other before running her tongue from your sack along the length of your veiny shaft to the tip of your cock.

"I rather eat some more meat than dessert," she purrs, locking eyes with yours as she swirls her tongue around your glans before engulfing it.

"Yeah..." you groan and barely notice in your peripheral vision of the other three girls stripping off their clothes while Sara takes more of your cock into her mouth.

You would love to let her keep sucking you off until you blow your load down her throat but fucking her huge tits is also tempting. Of course, having Sara straddle your cock is great too!
