Your big tits crammed with cock

You would love to suck a hot batch of cream from Goob's dick or ride his fat cock until he spews in your pussy, but you have other desires. While you're slurping on his slippery schlong you reach down to your bustier and unsnap the clasps. You open the garment like a vest and your huge, pale tits spill free.

You always cram them into overflowing Double-D-cups, but they've grown to G-cups. It's good genes and maybe a mamlarger tablet or two. Gray market stuff. Your luscious mounds are quite pert and firm for now, but you're young. You know you're going to have to invest in an anti-gravity bra if you want to keep them this firm as the years go by. Your areolas and nipples are dark pinkish-red, like wine against your pale titflesh. Your nipples are long and fat and very erect. You look up at Goob, still polishing his pole, a string of drool sliding down your chin, and you squeeze your big tits together and twist your nipples between fingers and thumbs.

"Oh, Hannah," Goob moans at the sight.

You pop your lips free from his dick and ask, "Want to fuck them?"

"Them?"

"My tits," you say leaning back and making them bounce up and down by squeezing your arms together. "Do you want to slide that big monkey dick between these?"

"I..I...I mean, I..."

You give him a wink and sprawl back on the floor of the workshop. You drag Goob towards you by his hard cock. He sinks to his knees straddling your toned tummy and at your direction the shy simian guides his precum-lubed pole to the soft mounds of your breasts. He lays his cock in the valley between your tits and, with a hand on either side of your huge breasts, you crush his cock bewtween your warm, soft tits. A quick up and down movement spreads the slippery slime dripping from his dick all over the insides of your cleavage.

"Now fuck them," you demand. "Fuck my big tits."

Goob is less hesitant now that you've got his fuckstick cinched between two of the biggest, softest tits this side of the galactic arm. With a grunt he begins fucking his dick into the tight channel formed between your tits. There's a bit of friction at first, a little extra heat, but his seeping precum soon fully lubes your cleavage. Goob's hairy legs brush the underside of your breasts and tickle your tummy.

The red, oozing head of his dick punches up from between your tits with each long stroke and you greet it with your mouth. It's long enough that with a little guidance from your talented tongue you can direct a good three inches into the waiting oval of your lips. Just enough time to give Goob's cock a quick suck before it pops free and disappears back into the dark canyon of your breasts.

"Mmmph yeah fuck mmmpphh my tits mmmph with that bi-mmmmph big dick!" you encourage him between mouthfuls of his hot cockhead.

Soon enough Goob is hooting like an ape and slamming you so hard your tits swing up and collide with your face on each powerful stroke of his hips. He truly fucking your cleavage and clearly he's about to cum.

"Spunk all over me," you squeal. "Cover me in your-"

Goob groans and a blast of white cream boils out of his cock's flaring tip and bastes your open mouth in a gooey splatter. Thrust after thrust hot cum spews out of Goob's cock and spunks up your chin, cheeks, and spills out from between your titties and pools in the divot below your throat. So much fills the spot that it soon gushes over both sides forming a warm necklace of cum. Goob finally relaxes and you release him from the prison of your naughty pillows and lean your head forward to draw the last drops from his dick with a suck and a stroke.

After a bit of a show of massaging his sticky sperm into your huge tits and scooping some into your mouth you sit up.

"That was," Goob sighs, "unexpected."

"Thanks for the pearl necklace. Now you just Keep running the engines like that and I'll keep rewarding you like this," you smile and stuff his softening shaft back into his overalls.

"Yes, Hannah, ma'am. Captain."

Goob watches your shapely ass as you depart. You decend using a ladder built into the engine housing and return to your quarters to shower and get a few hours sleep before the arrival at Omicron-69.
