Carry on

Tired of being gentle your wrap your hand in her hair, then lift one of her legs on to the dressing table. You start to build up pace again, thrusting hard once more into Susan's pussy, her screams and grunts get loud again, you look around at the open windows, the neighbours are in for a treat you think.

You pull on her hair, "open your eyes Susan, look at your sexy body whilst i fuck you, look at your breasts swinging with each thrust, look in my eyes, you can see how much want you, how much i love fucking your beautiful body" her eyes open, you see them filled with lust, you know this is the best sex she's ever had, your father couldn't satisfy her but now you can.

"You love this don't you Susan, you love your stepson's cock fucking you hard, your glad his limp dicked father left you, now you can have his son's cock whenever you want, now tickle his balls as he fucks you"

You feel and see her cum, quietly this time she gently massages your swinging balls, "ohhhh Greg, talk dirty to me make me feel like a dirty milf, taking advantage of her lonely stepson, i had more orgasms today than i ever had with your father" you smile to yourself, is this all because of the app, either way Susan yours mine now.
