Recieve a horse cock... the trouble begins...

You wake up feeling something straining in your pants. You look down to see that you have a huge penis now! You quickly pull down your pants and your panties only to realize that it is a horse's cock. it is sixteen inches in length. You blush in humiliation as you think about how to hide it. thankfully you don't have work today, but you do tomorrow. Suddenly you realize that you are unbearably horny and your hypersensitive breasts are begging for attention just as much as your horse cock is. you put your horse cock against your cleavage and squeezed your breasts into you horse cock. Twitching with pleasure, it feels like you are fucking your chest. You build up to a climax for ten minutes. As you climax, you shout licentiously into your pillow and cover it with internally-produced cum. After regaining your composure, you toss aside the pillow and get dressed. Your horse cock isn't so hard to hide in your panties when it is flaccid, although it does bulge quite a bit. Thankfully, your ass is much more noticeable than the bulge is. You relax for almost thirty minutes, then head into the kitchen to quickly grab some food.

Unfortunately, your highly sexually unrestrained sister is there. She notices you and says "Hey, come here! I'm making breakfast!" You then walk in and sit down at the table, immediately noticing her lack of modesty. She is dressed in semi-transparent panties and a loose jersey. As you daze out on her beautiful figure, she says, "I wanted to talk to you anyways. Whats with you having a huge thighs and now a bubble butt too? Don't tell be its a diet either." You find it hard to focus as she cooks in such revealing attire. Her nipples are visible, and her pussy is shaved. Eventually you answer "Huh? Oh. Yeah! Umm. sorry Brittney, I was thinking about something. I don't know. Maybe it's a reaction to something? I feel great though!" "Hmm... Well, okay. Breakfast is ready." She brings you a plate and a glass of milk, then she get some for herself as well. As she sits down at the table she spills her milk all over her shirt and lap. "Fuck!" She exclaims as she quickly strips nude and proceeds to clean her body and chair with napkins. You feel yourself already getting horny again as your horse cock begins to strain against the front of your panties. She sits back down and says "Sorry, don't mind me, we're family, so whatever." You wait as long as you can, trying to finish your plate quickly. You eat most of it, but you eventually are **** to to get up and quickly leave. "I've got to use the bathroom!" You exclaim as she suspiciously rises an eyebrow at your odd behavior.

You rush into the bathroom and pull out your rapidly hardening horse cock. You start frantically fucking your breasts again to get this over with quickly. After about six minutes, your impatient and suspicious sister barges into the room to see you fucking your breasts. She covers her mouth with a look of mortification as you accidentally ejaculate all over your face while moaning with delight. She runs into her room as you regain your composure for about ten minutes. After relaxing, you clean the bathroom and leave it without worrying about keeping your secret, thus, you don't bother to put your panties back on. As your horse cock already starts to harden again, it lifts your skirt, leaving you feeling exposed. As you walk to your room it sways back and fourth, enticing your eyes with every step.

As you get to your room you shut the door and cover your mouth in awe and disbelief of knowing that your sister knows about your huge horse cock now! "Fuck. Every half hour?!" You complain to yourself as you start to fuck your breasts again. It goes on for about ten minutes. After you ejaculate on your pillow once again, you say to yourself in exhaustion, "I have a really strong sex drive too now! ...Fuck!" You relax for about fifteen minutes, but you know you must now talk to your sister about what's happening. Knowing you don't have much more time, you quickly get dressed and go knock on your sister's bedroom door.

After you knock she shouts for you to come in, so you enter. She is still naked and laying on her bed. She says "Look... My inadvertently alluring way of avoiding the heat has never bothered you before and we both know that its just to damn hot to be dressed all proper. Also, I really don't care what you look like as long as I know I can trust you not to come on to me or something like that. I'm sorry if I invaded your privacy at all, but I was worried." "Its okay... and I'm okay. My body has been... changing, and it will likely continue to do so. Its... actually some kind of weird curse. I don't think I can stop it, but I don't really want to anyways." "If you say your alright, I trust you... so... umm... can I see it? ...Please, Addison?" You blush and start growing an erection at her request. As you try to cover yourself she approaches you saying "Stop hiding it! It's fine. I don't mind... I just want to see it." she says with a smile. She starts pulling down your panties only to have your huge and rapidly hardening cock spring forward and gently thwack her in the face. You were shutting your eyes and looking away as she inspected your newly multi-sexed nether region, but as promised, she only wanted a personal peek. She then says, "Damn. Well, you can have this back." She hands you your panties and continues, "As long as your alright you can curse up a storm or whatever. I know your a bit of a marshmallow brain so I'll tell mom about this for you, don't worry."

You leave with awe, but also acceptance. As you shut the door and walk to your room you only now realize that you never thought about your mom coming back. she was on vacation and will return in ten days. You decide not to worry about it for now and go to your room.

Brittany was right. It was to hot for clothes. Although, you are pretty sure that she just wants to see you naked, but you don't have much of a choice. As you undress your raging hard on gets you thinking that you may need practice suppressing your incredible sex drive. Now at ease with your exposure, you decide to take a naked walk around the house. However, seeing your hard horse cock swaying as you walk is only turning you on more. Eventually your lust becomes to great for you to hold back as you almost reflexively start fucking your breasts. Unknown to you, your sister just barely came around the corner and was watching you. You continue for ten minutes, as usual, until you climax. Suddenly realizing and remembering that you were in the kitchen, you climbed onto the counter and released you seed in the sink. As you wash the sink you hear your sister say "That was hot as fuck." You were surprised, but as you left you cleverly responded by smacking your bubble butt at her as you had to your room.

You shut the door and start to surf the web. With your increased sex drive though, it doesn't take long until your doing something you don't usually do, which is looking up porn. You masturbate while surfing page after page of porn that you've never considered before. After an enormous climax, you realize that you've lost track of time, and that it's time for bed. You shut down the computer, then lay in bed and doze off to sleep.
