I used to see this couple on the bus every morning...they were massive like a couple of sumo wrestlers only one was female. I used to sit there trying NOT to enviage them both naked and having sex. I used to think that it must have been a 'big' event just in the space needed, like hippopotamous mating. I used to sit there wondering if they had a 'docking procedure' and if it was difficult for them,..if she went on top and the sheer massive weight of her huge bulk smashing up and down.....the kind of bed they had or needed and if the whole house started to shake....if the neighbours used to moan and quake on a sunday morning or whenever......
