I had something similar happen the other week, turned out it was just my neighbour seeing if her mum was here.
Do your mate's mums frequently stay over at your place, like?
Maybe if you imagine it happening enough times Bry it might come true
I hope one day the fit mum from over the road, who wears amazingly tight skirts and heels for work knocks at mine and just pushes her self on to me and rides the **** out of me.
You are getting very frustrated Bry I suspect ha ha
