Tease her

You smile and push a little further, letting her tongue touch the tip as you fuck her tits. Sara’s head falls back in disappointment. "I want to suck you off!"

You let go of her tits and slide down to her flat belly. "You want to suck me?!" you tease, grabbing your cock and tapping it on her belly.

She nods, hungrily looking at your thick, veiny erection.

You stand up. "On your knees then."

With a squeal, she gets on her knees.

"Open your mouth," you command.

She does.

Taking your cock in your hand, you rub her lips with your tip. Lifting your cock, you bring your balls to her lips. She opens her mouth and sucks them one at a time while you slowly stroke your shaft.

"You like that, Mark?" Sara purrs.

"Mmmm, yeeessss..."

"Don't you want me to suck that big, fat cock next?"
