You stay and say that you want to offer your body.
They don't trust you and hold you with their strong hands... After speaking with an authority in the church, he says that you are a male, and your body is not prepared for the eldritch gods.

He forces you to lay on a chair and they put a small chastity cage, a corrupt nun starts to draw an eldritch tattoo on your belly, and you endure the pain... if you try to move, the cultists old your arms and force you to stay on the chair.
The nurse with a lewd voice and smiling says "Endure a bit more sweetie, It's almost done"
They make you use glasses and your vision is blurred.

The pain is terrible, your breasts hurt, frightened you moan with pain and fear.
The nurse takes a mirror, and your vision returns to normal "Do you like it?"
Your stomach churns... no... it can be real!

In the reflection of the mirror, you notice more than a tattoo, your body hair disappeared, your breasts and nipples are unnaturally big, your waist is smaller, your lips, your hair... your nails
Frightened, you try to move, but they hold your arms, you struggle but your body is weak and exhausted, you can barely move your legs.
The nun pierce your nipples, and you start to cry...
She crushes your balls with her hands and you suddenly ejaculate, crying and moaning like a little girl.
"The slut is ready" she says with an evil grin.

The cultists move you to a dim room, an authority, a big man with a huge cock enters and everyone leaves.
You try to move, but you can only cover your face, you try to beg him but you drool, moaning like a girl.
"Don't worry, I think that the eldritch god will accept your offering" he recomforts you.

Despite his calm tone and his kind words, he lifts your legs and brutally rapes your ass.
Crying in pain, you endure his powerful deep thrusts, until he ejaculates inside your rectum. His cock is so long and his semen so abundant that you think that his seed reached your bowels.

When he takes out his cock, with a disgusting noise, you start to leak his semen on the floor. But he put his cock inside you again.
"Not so fast slut, we need you full, or the gods will not be pleased" he rubs your belly laughing "Try to clench your ass or it will take longer"
You try to move his arms and stop this torture, but you can barely manage to move your hands and cover your face again.

You feel his big cock pounding your ass again, and with each thrust, you moan like a whore, the pain is difficult to endure, your ass is starting apart and you feel your guts moving and pressing inside your belly with each movement.
Finally, he cums again, and this time, you let escape a moan of pleasure from your mouth... Embarrassed you can believe it, you just cum? t can't be possible, you have too much pain.
The big man laughs "Well done, well done, just clench your ass and it will be quicker"

After a 3rd round, he cums again, but after filling you with his cum, he pulls out his cock and he gives you a few cumshots directly on your belly.
You are bloated like a balloon and the tattoo glows with a different shape.

He leaves the room, and the darkness envelops you. You listen to a creepy voice, saying that he accepts your offer.
You try to release and relieve yourself, but you can't, you are condemned to become a cum balloon and you don't know when you will be allowed to release.

THE END
Cum balloon ending

Task: On a chair, put a chastity cage and draw a symbol on your pelvis or lower belly using a sharpie. Act in pain and struggle. Shave your intimate parts, wear a wig, and rub your nipples. Put clothespins on your nipples to simulate the piercings. Press your balls with your hand and moan in pain. Wait 1 minute and lay on the floor, in a dim room. Imagine the big man, lift your legs and fuck your ass hard for 5 minutes. Spurt 100ml of warm lube or fake cum inside your ass. Take off the dildo and expel the lube on the floor. Fuck your ass again with the big dildo, 5 more minutes, and spurt 100ml of fake cum or lube. Don't expel. Repeat one more time and hold the lube or fake cum inside you. Take a 1500ml enema and spurt 50ml of warm lube or cum over your bloated belly. Turn off the lights and cum rubbing through the cage or using a vibrator. Don't expel the enema until you cum.
