I have a really bad back and my boyfriend gives incredible back massages. All I have to do is ask and he'll give me one. The problem is because we both work it is usually late at night and we're both tired, so he'll go straight to bed after one. Once and a while he will cop a feel jokingly, but for some reason it turns me on and then I am left awake and horny. How do I get it to turn into something more after he gives me a good rub down?
