So the day had arrived and Joan my mother in law was once more settled in one of our spare bedrooms. The excitement for me had been building all week and my wife Kath had been teasing me no end,
"Only 4 days until you can play with my Mum's panties."
"Only 3 days until you can stare at her tits," & so on.
We had collected her after we both finished work and brought her home and then we'd had a meal together & watched a bit of TV before going to bed. I then lay in bed whilst Kath teased me further,
"Just think she is just a few feet away, laying there in bed, probably rubbing her wet pussy right now, wishing it was you. Mmmm I can almost smell her cunt from here, hot & wet just dying for your hard cock."
I leaned across and grabbed my wife but she fended me off,
"No, No, you bad boy, you have got to save all that hot spunk for my Mum."
I reached for one of her tits again,
"Come on Kath, how am I really going to do it? I can't see your Mum just breaking especially with you around. No look I need something now."
Kath leaned forward and kissed my lips tenderly,
"Mmmmm I can see and feel that but I'm off limits, if you want some pussy this weekend, then it is going to be surrounded by grey hair, not black."
"But how?" I said in desperation.
"I don't know, but you had better come up with something because I'm feeling totally horny, but I'm saving all my lust for whatever happens between you and my Mum."
"What do you mean by that?"
"Well darling as I have continually told you, I might fancy joining in, or at least frig myself off whilst I watch."
Her hand brushed my hard cock under the duvet,
"You could always slip into my Mum's room now and just try it on, tell her I'm asleep and tell her how you have always fancied her and see what happens, you never know she might just give herself to you."
"It'll never work, what if she screams the house down?"
"Well if what you say is true about her flirting with you for all these years I'm sure she won't."
Suddenly we both heard a noise coming from the bedroom next to ours and then we heard the door to Joan's room open.
Kath gave me a push,
"This is your chance, she is going for a pee and she never locks the bathroom door, go on, just walk in on her."
"Fuck off, it'll never work."
"Go on quickly," and with a hefty shove Kath had pushed me out of the bed.
I heard the bathroom door close and with my stomach full of knots I opened our bedroom door and walked naked down the hall. As I approached the bathroom door I heard the tell tale tinkle of water hitting water. Joan was sitting on the toilet taking a piss.
I took a deep breath, knowing that at least Kath was compliant in this and if it all went wrong she might at least come to my rescue.
Naked I stood in front of the bathroom door and with one last deep breath I tugged down on the handle and pushed the door inward.
There was a little cry of anguish, but before Joan could say "I'm in here" I had walked in and caught her sitting directly in front of me, her pyjama bottoms around her ankles.
"Shit sorry Joan!"
Her mouth moved but nothing came out and that was simply because her gaze her shifted in a second to my semi-erect cock swinging out in front of me.
"I didn't realise you were in here," I continued but I made no move to leave.
She licked her lips and I saw her gulp, "It's okay," she sort of stammered, "I should have locked the door"
My cock had slowly twitched back to full erect state as I looked at my Mother in law sitting on the toilet and even though she had spoken her eyes had only glanced up for a second before dropping back to my cock.
"You like that?" I asked grabbing my erect cock and slowly fondling it.
"Don't" she said but there was no conviction in the word, said more in a whisper than a command.
"Why not?" I said as I toyed the end of my cock with my thumb spreading my pre-cum over my bell-end making it shine.
She started to breathe heavily, her chest rising & falling quickly as she watched.
