It isn't a sin. Let me help you cum. You've just turned 18 and your Sunday school teacher is ready. You come in early to help her out and almost immediately she starts hitting on you. You're confused. Isn't this bad? It doesn't feel bad. Because she wants you to keep your virginity she decides to show you another way to release. She sucks your cock beautifully all while moaning and encouraging you to cum. You can't hold it back. You're only used to your hand. You've only kissed 2 girls and now a woman is helping you become a man. You let go and bust a huge nut in her mouth and she sucks it up greedily as if she wants you to pass out from the amount of nastiness she's exuding. This can't be real. But it is. Now hurry and get dressed the pastor is coming.
