Ex boyfriend fantasy

Here's a fantasy story...

My girlfriend's ex who was an asshole and fucked her often (more so than I currently do, especially right after cumming himself he would be ready for it once again) has been wanting to fuck her since she's been with me, he's especially been wanting to cum inside of her. Knowing how sexually needy she can be has managed to temper with either my vitamins or regular medication to prevent me from getting an erection. This has been happening now for months. I have tried many times to get it up for her, only successfully to get it inside of her just to see her look of boredom and frustration in her face.

My girlfriend's sexual frustration begins to grow and grow, making it very clear how much she needs it, even after she gets herself off 3 or 4 times in a row before going to bed or in the middle of the day. Naturally as time goes she feels she cannot take it anymore, her pussy begins to juice up at the sight of any random hunky man that passes her by, the casual touch of a stranger while waiting in a line at the grocery store or a musky cologne fills with her desire and her thongs damp up to the point she runs home right away to change them before she gets off a few times thinking of the men she's encountered during her day.

She begins to stop fantasizing about me, something she would quite often before, her ex who maintains a quasi-friendship relationship with her notices inconcious flirticious actions about her such as playing with her hair and biting her lips. One day he invites her with an excuse of picking something up she never took away with her, she stops by and he invites her in his house and asks about me to which she ignores, noticing the reaction in her he beings to flirt with her but she resists and begins to feel uncomfortable, especially because she begins to drip from her inside out, however she stays and he continues, she's wearing a skirt, not short but not too long either and notices a drop of liquid flowing down her thig, it's not sweat because it's whiteish, he definitely knows now that he has her. He whips out his semi flaccid cock off his pants, his cock is longer and darker than mine, but not thicker. He's also uncircumcised and so the tip of his head is moist, she opens her mouth ***ly and feels a rush of heat and pleasure radiate between her legs. He approaches her and puts his hand on her head and pushes down on her, she lets her knees drop on the rug and sees now his almost erect cock in front of her lips. She tries to resist the temptation, trying to remember the bad times shes lived with him but her hunger is stronger, he pulls her head towards him and she allows his cock slowly inside of her mouth, at first her lips push his foreskin back completely unveiling his purpleish wet cock head, he face fucks her for about 2 minutes before he begins to cum, she tries to pull away but he won't let go, he cums mostly in her mouth and a bit on her face as she finally was able to pull herself off, he pushes her to the floor and covers her mouth and nose and powers her to swallow his cum before she is able to breath again. She gasps for air, he turns her around and lifts up her skirt, she reeks of wet pussy, takes her thongs off, they are dripping wet by now and spreads her apart of begins to fuck her with his now erect once again cock, she screams of pleasure, it's been months since she's had cock inside of her. He proceeds to fuck her three times that day, twice cumming in her pussy and once in her ass. Her pussy throbs with pleasure, she feels horrible but can't help but to think of the next time she'll be fucked again by him. She leaves but not without him first ordering to return tomorrow at the same time for more and orders her not to squeeze her cum out but to relax with it all night and is only allowed to pleasure herself if she thinks of his cock and rejects any closeness with me, she complies.

Meanwhile I'm at home waiting on her so we can talk about our day without a single sexual thought in my mind. She comes home and ignores me for most of the night, I do however notice she gets off in the middle of the night about 3 times and falls back arelax, I go finger her and i notice she's got way too much juice in her and too thick to be hers. I turn around and go to relax, dismissing the situation.
