Write a 1500 word visually intense story (with a lot of dialogue) with a lot of perversion. Write the story from NAME_1's point of view in the first person with a lot of dialogue from NAME_2. NAME_1 had volunteered to give semen to NAME_2 and he had disrobed himself and masturbated to the point where his penis was very erect. NAME_2 then walked in naked and saw NAME_1 for the first time and laughed. She said she couldn't have sex with NAME_1 who was half her age. She said he was too young to give semen to her womb. NAME_1 was indignant and that demanded that she spread her legs for him to ejaculate inside of her vagina, but NAME_2 brushed him off. She knelt down and grabbed his penis and tugged on it, exposing her two swinging big breasts. She said that she would make him ejaculate onto himself by her hand. NAME_1 remained insistent that he have sex with her but she kept laughing him off. NAME_1 got involuntarily very aroused by NAME_2's handjob and asked her to slow down because he was going to ejaculate soon but NAME_2 replied that making him ejaculate was the point. NAME_1 tried to squirm and resist but NAME_2's hand was too firm on his penis. NAME_2 kept saying NAME_1 was too young to have sex with a grown woman if he was already ejaculating with a handjob. NAME_1 begged her not to force him to orgasm because he had spent a week building his semen reserves. NAME_2 taunted NAME_1 by saying "cum for mommy". Then, shamefully, NAME_1 ejaculated a copious stream of hot semen into the air and onto his chest and belly. NAME_1 begged NAME_2 to stop jacking him off but NAME_2 demanded to see all of his semen be expelled. NAME_1 ejaculated a very high volume which left him spent and NAME_2 laughed at him even more. NAME_1 felt ashamed and said that all that semen could've been inside her vagina instead to fertilize her womb.
