He follows your advice.

Moving slowly at first, as if testing the feeling, he starts moving his hips. In and out, in and out, sliding his slippery penis between your cleavage, rubbing the soft skin with his own. You can't help but peek at it out of the corner of your eye. Is it good? You aren't even really having to do anything....

"D-does it feel good?" You ask, blush deepening. "Getting squeezed by my boobs?"

"Soft...." He grunts in reply. "And tight.... that shirt's making your cleavage so tight...."

You squeeze your hands together in your lap, blushing tremendously, and nibble at your bottom lip. If he likes it so far, then maybe if you.....

Slowly, testingly, you start to squeeze your arms together a bit, trying to make him feel even better in there. Your breasts are large enough to engulf him pretty well, and shape themselves around his cock quite nicely as you slowly apply pressure and push them together with your shoulders. Feeling yourself grow in confidence, you start rolling them up and down in opposite directions, wrapping around his dick even nicer.

All the while he keeps sliding in and out, in and out, slicking the inside of your chest up even more with copious precum mixing with the lube. He's going much faster now. Judging by his face, and the sounds of his grunting as he humps at the gap in your shirt, your tight cleavage is definitely beating his dick. It's a bit embarrassing, but also somewhat empowering.... are your boobs really that good?

You lean forward against him a bit more to test that idea, pushing back against his dick as if it were an enemy you were trying to fend off on the battlefield. You're starting to like this. Seeing how he reacts to it all is surprisingly fun.

In response, he speeds up significantly, ramming his dick through your shirt with a lot more urgency. With an involuntary gasp of pleasure and a skipping of your heart, you catch yourself, and lean back to a neutral position again, not wanting to take this too far. You're just here for a job, don't start acting dirty now...

Your face is burning red as you avert your eyes to the ground once more, kneeling with your hands folded in your lap as this man humps your tits recklessly through the gap between your shirt buttons. You're getting a real fucking, here.... how much longer can he keep going? Your marshmallow-soft tits are conforming with every motion of his dick, and your heart is skipping all over the place as he lets out another grunt.

"Your tits are pushing me too hard...." He groans.

Your blush deepens, the warmth from your face spreading almost through the entire room. Heat is coming up from his dick too, and it feels like it's fogging up your eyes a bit -- his penis' head is so engorged in there, it really feels like it's ready to burst.

You gently wag your torso from side to side, giving his cock a little encouragement shake to help it out. Taking in a sharp breath, and thrusting his hips desperately, it's at last too much for him to take, and he pops. Spray after spray of hot semen is short through your shirt, directly between your boobs.

"Oh!" You start, surprised by the sudden warmth as he continues rubbing against you, if a bit slower now. "Did it really feel that good...?"

You chew on your bottom lip again, staring at his dick as he catches his breath, leaning on your shoulders with both hands. He slowly pushes off of you, sliding his wilting cock out from your tight cleavage, and letting it droop just in front of you.

F-fuckk.... you're feeling really excited, and your heart's going crazy.... your breathing's all over the place, too....

He buckles his pants back up, and reaches forward to pat the top of your head with a 'phew'. You can't help but lean into his palm and shudder as rubs you there, and you feel a strange sadness as he turns to leave without doing anything more to you.

This guy really just shot into your chest, and all you're thinking about is what else he might do. M-maybe getting your ass fucked wouldn't have been so bad...? That's probably just the horny talking, though... you're feeling really hot, all the same.
