There is a knock at the door. It's one of my exes, who I still fantasise about even now. He tells me he can't stop thinking about me and has to have me.

I let him in and keep him waiting for ages, making him a coffee and chatting flirtatiously for hours. He ends up begging me to for sex. I eventually give in and he does everthing I want. I kick him out immediately afterwards, knowing that I won't need to fantasise about him again.
