"No"

I say, and then quickly add:

"I want you to go first, if you know what I mean..."

Millie gives me a naughty smile and slowly unbuttons her blouse, revealing her massive cleavage hidden under a white lace bra. She pauses briefly, gesturing for me to remove my pants. I quickly obey her, and as her blouse comes off my pants start to come off as well.

Millie gives my cock an appreciative look, then reaches behind her, and unclasps her bra, and her big tits are now right in front of me. They are incredibly nice, even bigger than I imagined, very firm looking, and with light brown aereolas and pointy nipples.

Millie lays down on the sofa, her big tits in the air, and she says:

"Fuck my tits Matt."

I quickly drop my pants fully and climb on top of her, then straddling her I place my dick between her big tits and use my hands to push them together, and they swallow my dick up completely.

I let my dick slide very slowly back and forth between Millie's big tits, enjoying how they feel around my cock, and also the amazing sight of Millie's big tits wrapped around my cock.

Millie is keeping her eyes closed, but her hands are moving slowly, first along my thighs, then up along my stomach and chest, then down along my back, until she reaches my buttocks. She grabs them gently with her hands, and starts pulling me towards her. She wants me to fuck her tits harder, I realise!

I start pushing back and forth between Millie's big tits at a faster pace then earlier, and while I am using my hands to push her breasts together around my dick, I am also making sure my fingers are giving her nipples ample attention.

Millie starts to moan a little, mumbling something I cannot really hear. Her big tits can easily make my cock disappear completely between them, and only the head of my dick becomes visible when I thrust my dick forwards.

Millie whispers:

"You like how my new tits feel like around your cock?"

"They are amazing." I whisper back.

Millie breathes out loudly a few times, then whispers:

"You like this, you like fucking my big tits?"

"Am loving it." I whisper.

Millie starts to moan slightly, and I feel I am close to cuming now, so I whisper:

"I am about to cum Millie."

"Cum on my big tits Matt." Millie whispers, and hearing that I feel my dick start to jump, and my cum spills out between Millie's tits. Millie squeezes my buttocks hard and let's out a loud moan when she feels my cum on her skin, and after I have finished cuming she uses her hands to rub my cum into the skin of her big tits, whispering:

"Cum is supposed to be great for the skin."
