There's no stopping him

Rob lowers his hands to yours and mashes the soft orbs of your breasts even tighter around his throbbing prick. His salty precum smears against your outstretched tongue with each upward thrust and oozes down his shaft to grease the valley between your breasts. He groans and fucks your tits with the **** of a man determined to get himself off. His cock is hot with friction. His swollen, purple cockhead pops out from your cleavage with each frantic thrust.

You had thoughts of climbing up onto his lap and giving him a ride, but it is apparent by the urgency of his thrusting that you'll be getting a face full at any moment. You decide to make the best of it, swirling your tongue around the head of his cock each time it comes into reach and looking up at him with lusty eyes.

"That's bloody amazing," Rob moans. "With your tongue...that...ohhhh yesss..."

You reply with a breathy, "Uh-huh" exhaled across his cock as it prods your tongue.

"Ohhhh!" Rob loses any ability to speak. He lifts up off the couch with each fevered stab of his slippery shaft between the inviting valley of your tits.

You feel his cock jerk and a thin spray of warm cum greets your mouth on the next upward thrust. His cock disappears and twitches again, emerging a moment later with a huge eruption of his hot sperm straight into your mouth. Most of it splashes across your tongue and slides out onto your breasts immediately. The tight mash of your tits is inundated with a third burst of cum and Rob gasps with pleasure as a fourth and fifth pump out across your lips and cleavage.

He holds his cock fully thrust into your cleavage as he finishes, his cock engorged and prodding your tongue, twitching slightly as the last orgasmic pearls drool out of the slit and spill against your lower lip.

"Oh my word," he laughs, giddy with pleasure. "That was incredible."

He relaxes his grip on your hands and you slowly do as well, allow your massive breasts to settle back into place on his lap.

"Mmmmm," you capture his still stiff cock in your mouth and give it a good suck, clearing the chamber of the last of his load. He winces from the sensation, but more enjoys the gentle licking you give him to clean up the traces of cum on his shaft.

You lean back when he's clean and make a show of cleaning off your cleavage. Your fingers scoop up the larger dollops and you catch his eye and suck the cum from your fingers with a greedy slurps. Your tongue cleans between your fingers as you pinch and squeeze your breasts with your other hand.

Rob enjoys the show as he catches his breath and is not too put off to kiss you on the lips when you slide up next to him on the couch. You give him a good kiss and let him feel your warm body against his, reminding him that you have yet to get your rocks off.
