I decide to fuck Millie's tits

I look over at Millie, who is leaning back against the back of the sofa, looking exhausted and shocked. Then I look down at my cock, it is so hard that it is bouncing a bit up and down, I was almost at the point of cumming when Mistress Jada came and then abruptly stopped me enjoying the pleasure of her ass.

Then I remember what she said, I can use Millie's tits to bring myself over the edge if I decide to.

I walk up to Millie and let my cock dangle near her face. She looks back up at me, clearly annoyed asking:

"What the hell Matt, what are you doing?"

"Not so loud." I whisper, then continue: "She might hear us."

"Whatever Matt." Millie responds, then says:

"Get your cock out of my face, will you." In a slightly louder voice.

"You heard Mistress Jada, you need to use your tits to pleasure me!" I hiss at Millie, in a somewhat irritated tone.

Millie looks up at me, her eyes narrowing, thinking for a few seconds, then says:

"You seem to be enjoying this predicament we are in too much Matt, are you somehow involved in this?"

"No, how could you say that?" I respond, trying to sound as surprised and innocent as I can, looking down at her.

"Good, then get your cock out of my face while I think up a plan."

Millie replies, then closes her eyes and leans backwards.

Then I hear the door open behind me. Millie quickly sits up straight, looking at the door in fear.
