"M-my mouth?" Melissa repeated, shocked at the sight of the fat cock in front of her. Though she was no stranger to giving head, since she and Conner had some tendencies to experiment all sorts of things behind closed doors. But, the fact that she has to do it to a man that isn't her husband gave her pause.
No, I have to do it... for Tyler. She thought to herself as she got on her knees. Now face to face with a cock that was fatter than her husband's, Melissa stared at it for a few moments.
W-will this even fit my mouth? N-no, it has to... Her thoughts raced as she opens her mouth, leaning in to give his cockhead a lick while her right hand strokes his shaft.
