Convince her to give me a handjob

"It's okay Millie." I say, stroking her cheek with my hand.

"I'm sorry Matt, it's just that... You are my step-son and this feels wrong." Millie replies.

"I understand." I reply, then: "Can I see your breasts?"

"Matt, you really don't listen, do you?" Millie sighs, looking up at the ceiling.

"Well, it is just that, you have seen my..." I say and look down at my cock.

This argument seems to win Millie over, and she pulls her top over her head, revealing her big breasts contained in a tiny white lace bra.

"There. You happy now?" She says and looks at me.

"Well, it's just that I'd like to see them... In freedom." I reply, looking at her pleadingly.

Millie sighs and reaches behind her, undoing her bra. Her big tits tumble out, but they are very firm so they don't drop far. They look so nice with pointy light brown nipples surrounded by large aereolas.

I immediately reach for them, but Millie pushes my hand away, saying:

"Matt, we should get going now."

I look at her, then down at my cock. Millie stares back at me, stale mate. Then, I quickly pull my phone out of my pocket and take a picture of Millie topless.

"Hey!" Millie shouts in anger, reaching for my phone.

"Don't even try it." I say, then: "One click and it goes on Instagram."

Millie lounges for the phone, but I hold it away from her. She sits back down, glaring at me.

"Do you want me to delete the picture?" I ask her.

"Matt, this is childish." Millie replies.

"Do you want the picture deleted?" I ask again.

"Yes Matt, I want you to delete the picture." Millie sighs.

"Use your mouth to convince me." I reply.

"Huh?" Millie says.

"Your mouth." I say. "I am sure you know it can be used for other things than talking."

"Matt, I am not sucking your cock." Millie replies, shaking her head.

"Hand?" I ask, trying to look like I am compromising.

Millie rolls her eyes and says:

"Deal."
