The week that followed the creaky floorboard incident was a busy one for me, stressful too. We had some family issues that I won't go into.
After describing what had happened over at Chris's place that night John started to come round to my way of thinking.
He'd originally been sceptical of Barbara's previous weird behaviour, passing it off as the woman being drunk. But John knows when I'm telling the truth and when I'm genuinely freaked out.
And I know what I heard. The creaky floorboard near Chris's bedroom door is a familiar noise on approaching, we always trigger it.
My hubby enquired if I'd told Chris about what I'd heard? Although occupied both physically and otherwise at the time I did bring the subject up shortly afterwards.
Chris played it down, claiming it was probably the movement of his bed. But if that were the case then how come I had not heard it before during our play times?
Not wanting to sound paranoid, I didn't press him with that question.
After we'd gotten dressed and come out the bedroom, while Chris was in the bathroom having a pee, I checked the front door which was still locked. Again, not wanting to appear paranoid in front of Chris I only had time to check the living room before he'd finished, it was empty.
But that doesn't prove anything, Barbara could have just locked the door again after entry and been hiding in her bedroom.
But why? Why go to all this trouble to listen to your own son doing that to his girlfriend?
Time will eventually reveal the answer to that question, and with it a shock discovery.
But for now, back to my busy week. After saturday nights role play and subsequent exhausting work out on young Chris's squeaky little bed, I had a hungry husband to return home to...so no rest for the wicked...I guess that's me.
John is just as enthusiastic knowing I've recently been with another man, as he is whilst watching or taking part.
He has confided that not playing any physical part in the process has a special quality unlike any other experience.
While I'm with my boyfriend, his imagination is running amok, giving him a special rush like no other.
The rest of my weekend goes by eneventfully, the same for monday except for Rita being absent from work once again, I wonder what the reason will be this time...
Probably another mishap, she seems to be cursed with clumsiness.
A bruised cheek or black eye here, broken finger there...etc.
I am beginning to worry about the nature of my good friends relationship with her husband, the guy she never wants to talk about.
You don't want to think the worst, but there are a few warning signs.
That evening sees me do an impromptu phone sex session with Chris. My young boyfriend phoning me on the evening unexpectedly.
I'm sat in the living room with John and Steve watching a rerun of star trek voyager, the one where tuvok gets sex rage, or pon farr as it's called on vulcan.
Steve, our youngest son has developed a taste for sci fi and could be considered a trekkie. During the show my mobile goes off in the kitchen and I go and answer it to Chris who's feeling lonely...and chatty.
So I took him upstairs to our bedroom and we initially talked about everyday things...ordinary stuff.
But the conversation soon took on a more naughty nature, Chris asking me what I was doing but more daringly asking what I was wearing, original...I know.
I tell him the truth, I'm wearing rather unsexy pink pyjamas.
But then everything changes on a dime with Chris's next enquiry, he reminds me that I was going to tell him my fantasies one day, and could I reveal one of them now?
I kind of knew where the conversation was going anyway but then I was sure.
Quickly pondering which of many I could safely reveal to naive Chris.
Despite what I've exposed him to, the pup still has a long way to go and I wouldn't want to scare him off with something extreme from my dark side.
So, I start him with a tame one, although this is more of a kink than fantasy.
I tell the young lad, who's all ears, about my submissive side and how I like to be dominated.
Keeping my voice down low, describing how it turns me on to be taken control of in every way.
Explaining in detail how excited I become when physically restrained.
When I'm finished there is silence from Chris for too long and it begins to worry me so I ask if he's alright?
A quiet 'yeah' followed by more silence then, in a meek and cautious way, he asks if I like being tied up?
Explaining to my eager listener that yes I do but prefer to be manually restrained, there is another short period of silence before another even quieter reply, "Would you....would you let me tie you up?"
By now it's obvious to me that Chris is highly aroused, he's probably in his bedroom nursing a hard on, so I play a little game.
"If I let you tie me up will you do something for me?"
I can just about see his red face wearing a furtive, excited look, phone pressed up to his ear, "yeah."
His secretive response.
I ask if he's alone in his bedroom....he is.
"And is your mum in?"
She is.
"Lock your bedroom door."
Chris informs me that it's already locked.
Bringing the phone closer to my lips, "Good....now firstly have you got some tissues to hand?...good...your going to need those...now Chris I want you to listen very carefully to my voice...can you do that for me honey?"
It's a meek and barely audible 'yeah' from young Chris.
Next I ask him if he's hard.
He is.
"Good boy...now...take all your clothes off and lay down on your bed..."
He does as he's told, I can hear the familiar creak of bed spring as he mounts the bed.
"...that's it...now sweetheart I want you to imagine I'm there with you ok?"
I hear a whispered 'ok' from my phone.
It feels strange but also exciting knowing my own son is downstairs watching TV with his dad while I talk someone else's son through a masturbation session...and at the same time daring and bold, like I'm getting one over on his mum Barbara.
