"Let's put it between your big tits"

I reply, mentally crossing my fingers that she will say yes.

Millie thinks for a few seconds, then says:

"Ok, but my bra stays on."

Millie is seated in front of me, with her shirt unzipped revealing her sports bra underneath, so I step forward until my cock is right in front of her chest, and the tip is touching her big tits.

Millie looks at my rock hard cock appreciatively and says:

"I can tell you really like my big tits." She takes her eyes away from my cock and looks up at me and smiles, then she looks back at my cock.

I rub my cock on her tits, then Millie shifts her arms so that her big tits squeeze together, and I push my cock between them. Her big tits feel amazing on my cock, even though they are still in her sports bra. I push back and forth a few times, and moan with pleasure. Millie keeps starring at my rock hard cock, it is like she is mesmerised by it.

I increase the pace I am using to slide my cock between Millie's big tits, and Millie moves her arms down. Her tits come apart around my cock, I feel a bit disappointed, but then she quickly moves her hands up to push her tits together.

Millie using her hands to push her tits together makes them hug my cock even tighter, and feeling the mass of her tits around my cock is turning me on incredibly.

Millie looks up at me as I am fucking her bra covered tits. She just maintains eye contact for a while, then says:

"You like how my big tits feel around your cock."

That brings me over the edge, and my cock starts spewing cum on Millie's sports bra.

Millie feels my cum making her bra wet, and she looks down at it, and seems very content.

"I still got it, don't I?" She says.

"You sure do, Millie." I reply.
