Tell me a detailed sex story about a birthday celebration where a guy starts out the day eating out his wife NAME_1 and his wife's friend NAME_2. Then the ladies tells him he can fuck NAME_2, but when NAME_2 sees his cock she invites 13 guys bigger than 8 inches and teases him about how she and his wife will never feel his tiny cock. The husband NAME_3 is forced to eat out both women and they both get fucked till they are covered in cum. He is then told he can only fuck NAME_2 while cleaning his wife out. They ridicule him and a one day sex party turns into a fuckfest till his wife is pregnant.
