picking up gf SeXStoRY

Hi this is my first story so it be short but hot.. well im a 25 yr old ordinary guy in a relationship with a 20 sexy year old girl. She is quite conservative and only slept with me. She went on a trip to visit her f****y just for a week and when she arrived there was something different about her. i saw her walking out of security wearing some high heels stockings and quite a short and tight skimpy dress, as i aproached her she just gave me a kiss and noticed a wierd taste in her mouth said here take my bag. i noticed she had changed and maybe bit more bossy but still her on the drive home i asked her how shed been doing for the past week and that i was so horny and i needed to unload. the conversation turned into sex and she just blurted out for the past week i havent had sex with nobody else so i need you to eat my pussy. when we got home she just put her panties to one side and told me come on im waiting... when she came from my oral skills, i was gonna get up when she said stay there and carry on i got to explain a few changes thats gonna happen in our relationship. so i just reassumed the position and kept going down on her. she then started saying before when i told you i had not cheated on you i meant sex but to to tell you the truth ive had so much sperm on my body and down my throat and really enjoyed it as its been from black men. i just froze and starting leaking precum. she noticed this and said just how my black friends told me you like being a cuckold. they also told me how you should treat me like your slut and fuck me with strap ons and service me after my black friends fuck or play with me some changes are im gonna start wearing slutty clothes to attract more black attention. i want you to lick me and worship my feet and legs like if its the only way to survive. from now on you dont have no saying for your sexual life as im going to do a lot of experimenting with your and other people. and last your gonna be kept with a cock cage that my friends came on afew times so enjoy and she said i bet you dont know what the taste in my mouth was earlier and smiled cheekily.
