Walk up behind Millie

I stand up, but rather than leave I walk up so I am standing behind Millie and put my hand on her hips, my dick pushing against her ass through her silk bathrobe.

"Matt, we can't." Millie says in a soft tone of voice.

I don't respond, instead moving my hands along the side of her body, upwards toward her stomach, then with one quick move I cup both of her big tits.

Millie's body tenses up instantly. Her hands grab mine to pull them of her tits, and in a stern voice she says:

"Wow! No!"

I use my hands to then spin Millie around towards me, and try to kiss her, but she struggles against me, turning her head away. We struggle for a few seconds, then Millie makes a sudden jerky move to get out of my grasp and ends up falling onto her bed on her stomach, bent over with her face down.

I instantly get behind my step-mom, pushing her down with both hands and grinding my hips against her ass. Millie struggles violently, but I am stronger then her so she can't get up. We struggle for a while, and her bath robe rides up over her ass so my dick is now rubbing against her naked ass.

"Matt! No!"

Millie shouts as my dick pushes against her butt and thighs. Millie starts to buck a lot, trying to escape from me holding her down, and she also is pressing her thighs together, trying to prevent my dick from going between them.

I start pushing with my dick against Millie's thighs, and she is doing her best to resist me, then she says in a calm voice:

"Matt, if you stop now I will give you a handjob."

I momentarily pause on hearing this, then I quickly reply.
