"... You'll become a gigantic, tasty fat bear. You'll be very hairy, your cock will have an 15 inch, smelly and lewd cock, with hairy, gigantic balls to go along with. You'll become taller, at almost 7 feet, and weight 500 pounds. Your cum will be extremely thick, addictive, aphrodisiac and delicious, and you'll have loads and loads of it, with no refractory period to speak of. For your dare, you will use the curse to finish my transformation quickly and dare me to become your loyal cum loving slut"
Liam moaned at every word, as Kyle kept on stroking his cock and caressing his balls, kissing him in between phrases and playing with his butt. That didn't stop him from pleasuring Kyle either, as he began sucking and licking and kissing Kyle's delicious cock and balls, using what little he had seen from porn as a base, but it seemed enough, giving what would happen next.
He gasped for air as his transformation began. First, a roaring sound came from his belly as his whole body began to gain fat and muscles, his belly expanding each second. He gained a pair of male breasts with very hard and suckable nipples, as his dick began to outgrown his belly, ending with the promised 15 inches. He then felt weight coming to his balls, as his legs were forced apart to give room for them, almost like he was carrying to small babies. They each reached the size of gimmnastic's balls, and his sack was basically a forest. His clothes were all torn apart, and the hair began to grow in almost his whole body. He moaned and groaned and could feel everything getting smaller as his height increased from his 5'5'' to an outstanding 7', almost doubling down Kyle, who seemed very fragile and frowny and feminine in comparison. Liam then felt the cum filling his gigantic balls, and it made him horny. His pounds were finally finishing, giving him an amazing belly, hips, a gigantic jiggly butt and lots of muscles hidden underneath, so he was able to move almost as normal, and he didn't feel dragged down.
"Kyle..." Liam stopped himself at his new, engorged voice. Really turned Kyle on, and Liam by consequence "Transform Or Dare?" "Both" Kyle said excitedly, as he went to stroke his new master's cock. "Damn" Kyle thought "Even without the curse I think of him as my master already? Holy shit... Doesn't matter, I love it."
Kyle started to lick and stroke this massive cock as Liam spoke, between what seemed more like low animal growls then moans of pleasure: "You'll finish you ongoing transformation, and become a slutty trap like Jen stated. However, it'll not be permanent and you'll stay with your conscience, even though you'll be more horny and slutty than ever. For your dare, you shall become my cock craving slut untill I say so."
Kyle felt his body changing, but kept going hard on his attempt at a blowjob. Even with his apparent habillites given by the curse, Kyle was having problems yet. But not for long. He could feel his butt expanding and back arching as it acquired whore-ish proportions, jiggling and shaking as he boobed his head engulfing Liam's cock, that seemed more delicious and easier to deepthroat each second. 3, 4, 5, 7 inches already. His face changed into a very girly and slutty one, as his lips plumped and became whore-red, perfect for blowjobs and kissing and begging his master to fuck him. His hair grew and got tied into two side ponytails, giving him a childish look, which turned Liam on in a way he couldn't believe. Kyle's muscles dissipated and he even gained a pair of probably B cups and bigger nipples and areola, which gave Liam an idea for later. Kyle then became even smaller, barely a 5'2'', and his cock finished expanding. Then, Kyle managed to put the whole 15 inches into his mouth.
Liam was so focused on the transformation itself that he was caught by suprise and came on the spot, sending almost a gallon of cum to Kyle's mouth and insides. Kyle's stomache started to expand a little as his mouth leaked lots of cum, and his cock also shot cum in Liam's fat belly. He kept on trying to swallow but couldn't, and Liam took a long time to notice, but removed his cock. A burst of cum erupted but Kyle didn't seem to mind, lost in pleasure and lust, stomach still bloated, and more cum shot from his own dick.
