You are going to cum without penetrating me, you are prohibited from doing so
When it’s your birthday and your wife gives you a whore like this, you don’t expect it to be like that at all. The first rule is that no penetration. That is, he could do whatever he wanted as long as his cock didn’t enter her pussy or her ass. But since everything else was worth it, she started sucking his cock and then playing with him. Due to the simple fact that the game was prohibited it was a little more dangerous, she jerked him off just touching her pussy. They both knew that his cock couldn’t end up inside, but maybe a touch of her vaginal fluids would make him realize what he was missing. In the end they both followed the rules and he came without penetrating her.
