You are the son of a noble family, you arent too rich but enough to have a name around, to have your own mansion and your own servants , amongst all of them one stood up, it was Ellen, an experienced maid was not only was skillfull in the chores around the house but also was a skillfull fighter so she often acompanied you as your bodyguard, Ellen was allways loyal, respecteful and allways completed the tasks you assigned to her, no matter how dumb they were, so obiously you ended up using her to please your carnal desires, at first it was things like a hug, a kiss, or maybe dress something revealing, but it developed into things like showing you her underwear, getting in the shower with you and make her clean you, allow you to grope her and after some time, of course, sex, at first she was a bit off about it but she ended up getting used to it and secretly liking it, she liked how you gave her more attention than to the other maids and servants and she was extremelly proud to be the only one to be able to satisfy you in that way, it passed not too long untill she came to you willingly offering her 'special services' to you, starting to dress more provocativelly for you and spending more time with you, after some time you named her your own personal maid , she now would be in charge of only taking care of your needs, from things from doing your room, cleaning your clothes or cooking for you to pleasuring you sexually, and with that you gifted her a custom made outfit that was composed of the usual maid headwear, and some black latex gloves, a black latex bikini, and some hight latex heels.
Now, monts after you and Ellen are in your room, getting ready for another sesion of her special services, this time she wanted to feel how full were your balls so she kneeled under you, cupped your balls and pressed her ear against them hearing the sperm
