Hell yes

You swiftly push your dick into her, your balls slapping againast her ass. You slowly pull back again, just leaving the tip inside of Susan, her eyes open staring at you lustfully. You slam your cock back into her causing her tits to shudder as you slap against her again.

"Oh god yes" she screams again, "fuck me hard, i need you to fuck me hard." Susan, your step mom has changed now, the shy reserved woman who brought you up from 10 years old is begging to be fucked. You start to build a steady pace, pulling back before hammering back in hard. Each time she screams as your balls slap her ass. You need to see more of her body, your hands grip her tits, you look down at her, she loves the hard fuck your giving her, you try to unbutton her dress but soon struggle, so you rip it open exposing her slim sexy body, her tits continue to shudder as you move in and out. You lean forward and suck on her hard nipples, "thats it" she moans, "my nipples are so sensitive, keep sucking, flick them with your tongue" as you do so you feel her pussy walls spasm around you, "yes, I'm cuming again, ah, ah, ahhh" she tenses hard, her juices leaking out onto the table, the warmth of her on your cock soon has you needing to cum. "I'm goning to cum" you groan, "not inside me, cum on my body" she begs. You pull out, you rub you tip against her clit, she shudders again, you feel pressure building and start to rub your cock, finally your cum srays out up her stomach and onto her breats, stream after stream covers her body. Your legs go weak and you fall onto a chair. You look at the sight in front of you, the women you thought of as your step mother yesterday lays on the dinner table, still breathing heavily, her dress is ripped open, her body covered in your spunk.

This has definately changed your relationship.
