Explicit "All in all, i think we got out pretty nicely." My girlfriend laughed. That's easy for her to say! When her and I got on the bad side of a witch, she cursed us to fuse. I became my girlfriend's very own cock, which I guess was her punishment, too? Ugh but she seems happy about this! NSFW

I don't care how much of an ass man you claim you are, don't let your girl sit on your face if she's magic! My witch GF asked to and when she did I felt my body slipping away. She giggled excitedly, having learned a new curse to play with. "Don't worry, it only lasts 7 days." A week as her ass!? NSFW

I think I may just not reverse this." My girlfriend laughed as she ran a hand along me. I cried out but this was my fate NSFW

Explicit My girlfriend laughed, deeply amused by her new toy. Her new cock. It just so happened that cock was me. She said she always wondered what it was like to have a dick, and one day she found a spell that required a friend. Well, she chose me against my protests-mmmph sorry, cumming what was I saying?

Explicit "Haha, mmmph, maybe I need to increase the refractory period." The woman above me laughed, cum exploding from my mouth. She was a mad scientist who had captured me in my sleep. Through extensive experimentation she had transformed me into... this, her cock. Now she was adjusting her experience. NSFW

She didn't refer to me as a person, she constantly spoke as if I were nothing more than her cock. She had made me smaller, larger, made my balls smaller, and larger. Now she was adjusting the orgasms, she had upped it a bit much so I couldn't think straight. In fact, I figured this was intentional. She was using this as a way to break my mind and make me nothing but a true cock. She held the glass against my tip, cum still exploding out of me.

"Hmm o-once done I'll dial this back and... ah... subject 16 will be a perfect new ph-phallus for me... good boy, you've helped me achieve a dream of mine. Awww, don't be sad, your life wasn't going to amount to much anyway. When the scientific and medical communities see what I can do with my tech, nobody will ever care who you were before. Well, cause they'll never know." She whispered as I came one last time, my mind seemingly splintering. She shuddered, but laughed at the final rope of cum that sealed my fate.

I may be, unfortunately, stuck as her dick in a car ride to... gag fuck my own sister. She can hear my thoughts, how do I convince her to not go through with this!?

You and your friend had arranged to meet at his place to try out a strange spell written in an old notebook. When you both cast the spell, thick smoke appeared out of nowhere, and you began to merge and transform. You were the first to stir, feeling your body grow rigid and sensing a strange fluid oozing from your mouth; you tried to move but found yourself barely able to. Meanwhile, your friend got up a few seconds later. "What happened...?" he asked in a feminine voice. Neither of you could believe what was unfolding: your friend had transformed into a woman nearly two meters tall, and you had transformed into her massive penis. She stood up, staring at her body in horror, and touched you with one of her hands. "Did that spell fuse the two of us into this girl...?" She spoke in confusion while you struggled to hold back from ejaculating.

Now, they must get used to their new life fused together until there is a solution (which will probably never happen).

Explicit "I thought turning you into a dick would be humiliating enough, seeing as you refuse to learn your lesson, lets make you bigger." My roommate's girlfriend laughed. She had caught me peeping when she stayed one night and used some power to turn me into her cock. Now she was punishing me further! NSFW

Explicit The universe can be cruel. One moment I'm kneeling to propose to my girlfriend, the next, in a flash of light, we find ourselves trapped across town.

Used as a Ritual Component. NSFW

Planar binding a powerful succubus would've been beyond Maxines abilities due to the very nature of the ritual itself requiring a component that she lacks.

Luckily she has you as her boyfriend and a witch such as herself is nothing but resourceful. You recall what she whispered into your ear this morning as you laid next to her, your naked bodies intereined from last night's activity. "I wanna try something new tonight...I want you closer than ever before" She said as she placed a kiss laced with a pleasurable tingle upon your neck.

Eagerly you get out of work early, having finished your duties and hard as a rock you arrive home and strip down for the evenings experience with Maxine.

But once you enter your bedroom you freeze...your muscles refuse to obey you as you observe the sight before you. Maxine stands naked before a summoning circle lined in salt with numerous glyphs inscribed within and an offering splayed out around the portal to a more infernal plane of existence.

"Hear me and approach my consort" a meaning imoled for you and whatever lay beyond the veil between this reality and the next. From the portal is pulled a devil of striking resemblance to Maxine and you are shunted to your knees before the splendor of your beloved Maxine as she lays a hand upon your head.

"I love you...this is your destiny....let us join together my love" as she leaves these words into your mind your body obeys the hexes interwoven within the words. You lay down upon the floor and she positions her groin just above your rear.

Flesh joins flesh as you feel your body begin to compress inwards. Your legs lose their form as they begin to morph into a heavy sack, containing two powerful cum factories that begin to churn and gurgled with the transformation. Your arms join your torso and they lose their form, having become obsolete by the spells command and melding with the rest of you body as if they never existed. Your hair is gone and your bones, organs and form morph into a witch's cock.

Your face is stretched over a swollen cock. You lose your ability to hear and see and you want to cry out but can't as your vocal cords no longer exist. Your mouth is soft and you can still taste but it is overwhelmed by the seed that rapidly spills forth vomiting a torrent of potent seed upon the form of the succubus and the lines of the summoning circle.

Your consciousness remains and you see and hear what Maxine feels. You cry out to her but if she heard your plea she makes no indication.

With an animalistic intent Maxine and the succubus lunge at one another and you feel your head driven into the warmest and tightest place you've ever felt.

Your mind is subsumed in pleasure as you spit out precum. You feel your new "body" being abused by the pair that have no intent of stopping this session of passion.

Maxine feels her watermelon sized balls clench upward and her new cock twitch and spasm as she finishes the ritual of planar binding. Pumping gallon after gallon into the voracious pussy of the devil splayed out on the bed, Maxine pulls out of her.

For you everything goes quiet as the two cuddle up on the bed. You feel your sense of self remain trapped and unable to affect anything. This is your fate. This has always been your purpose. You are a cock. You will always be Maxine's cock.
