Continue as planned.

I look at her finger to my temple and think 'when you see me you will think I am your husband.' I quietly slip in and close the door most of the way behind me. I pull off my t-shirt and my socks watching as she continues fucking herself, her eyes closed and moaning. I pull off my pants and my boxers and finally release my raging hard-on. I take my cock in my hand and start stroking as I approach the shower, waiting for her to see me at any time. Apparently she is so caught up in her own pleasure she doesn't even notice as I open the door, in fact it seems that as I do she wants more and reaches one of her hands back and slides a finger into her asshole.

I stand there for a moment watching her fuck herself in both holes, so caught up in her own pleasure that she hasn't even seen me yet. I think about saying something then realize she has opened up a perfect potion for me. With only the one hand on the opposite wall, I slide into the shower right in front of her. I look down and see her head inches from my cock. I'm not sure if dad would do this but I sure as hell am going to, I line my throbbing cock up with her open mouth and shove it into her mouth.

At this point I was expecting her to look up wide eyed in shock, or to freeze, or something. But to my surprise without even opening an eye she moans on my cock and sucks it deep down her throat. Surprised I grab the back of her head and shove it balls deep down her throat, and start fucking her face. I suddenly wonder if my step-mom is a slut as she is now just sucking a cock that appeared in her mouth, but i gotta say she is defiantly good at it. I run my hand down her back and give her ass a hard slap, she jumps slightly but then sucks my cock harder and picks up her pace on her dildo. I slap her ass again and she moves her hand from her ass and grabs my cock hard. I slide my two fingers into her asshole and she moans on my cock. God I'm not going to last long at this rate. Seeing as she is now sliding back and forth between the dildo on the wall and my cock in her throat I take the hand from behind her head and slap her ass even harder while hooking her asshole. She moans and goes crazy on my cock so I continue to slap her ass alternating between cheeks. She moans and I can't tell she starts cumming as her body starts to tremble, watching her cum send me right over the edge and I start cumming down her throat, thrusting as deep as I can I feel her throat pulsing around my cock as she swallows my cum.

As my orgasm subsides I pull my dick out of her mouth and then move myself towards her, forcing her to rise but make sure she doesn't take her pussy off the dildo behind her. As her head reaches eye level she finally opens her eyes and sees me and smiles seductively.

"Do you normally suck strange cocks?" I say looking into her eyes.

"I knew it was your cock from the moment you stuck it in my mouth." she say and grabs my semi-hard cock and starts to stroke it. As she does I grab her hips and shove her back hard on the dildo. She gasps and I kiss her hard. As I kiss her I move her hips back and forward forcing the dildo in and out of her pussy, she matches my pace with her strokes, breathing life back into my cock as it grows again.

I break the kiss and put a finger to my temple and say "I only have a short time as I have to be back on a plane soon, but I wanted you."

"You have me, take me." She says with lust in her eyes.
