Roughly weekly the following will happen:
BF will go to bed to watch TV or read, and I'll join him a bit later (before he goes to sleep). We'll have a general chat, a bit of a cuddle, my hands might start wandering south... and then he's tired and wants to go to sleep. Slightly annoying, but still, his body and his rules. I'll get into my sleeping position (on my side with my back to him; he knows it's how I sleep and not to read anything into it) and try to nod off.
Anyway, you know that delicious moment when you're simultaneously awake and asleep, the duvet is devouring you, and your thoughts start merging into dreams? I bloody love that moment. What I don't love is that moment being interrupted by my BF jabbing his hard-on into my back and making hopeful grunty noises.
I'll abruptly wake up and drowsily respond with something quite reasonable, such as "it's half past fucking one!" ("you had your chance earlier!" being implicit within that) and await his next move, which varies between conceding defeat and going to sleep, or vigorously wanking.
As lightheartedish as this thread is, could someone re-assure me they have a similar set up...?
