I don't own, work for or know anyone who does own and or works for Nick and Nick's The Thundermens in any way. This story is my own.

Billy never thought he be naked in his sister's room getting a blow job. As to which sister was sucking him he had no clue, as he was blindfolded. As to why one of his sisters was giving him a blow job was because Billy had turned sixteen.

He was much taller now. Billy may be older but Billy still had that cute face of his.

As for his dick it was also big and fat. His sister was doing their best to suck away on his twelve inch hard dick. His balls were also big as his sister sucked away one hand was jacking him off while the other was fondling his balls. It wasn't much longer until he shot his load into his sister's mouth.

She had no choice but to swallow such a massive load. Billy's sister thought about having him eat her out but then decided not to. Mostly because she did not know if he would if she pushed her pussy in Billy's face. Lucky for Billy's sister her pussy was soaking wet.

She stood up and pushed Billy onto his back before standing onto the bed and hovering over her brother's naked body. As she lowered herself she took hold of Billy's dick and aimed it at her pussy. She slowly lowered herself down onto Billy's huge fat dick stretching her pussy.

This caused her to moan as well as Billy. She took a bit to get used to such a dick before riding her brother's dick. As she bounced away not only made her breasts bounce around but also made the siblings moan. Billy's sister continues to ride Billy's dick faster and faster causing her to squirt.

She soon lifted Billy up a bit so he was sitting. Her hands around Billy's neck as she fucked herself away. After a few more bounces she was squirting again. As she was she pushed Billy's face into her breasts. He soon was sucking on one of them and fondled the other as he thrusted his huge dick into his sister.

After a few more thrusts Billy made his sister squirt again. Billy managed to make his sister squirt four more times before he was on edge. Something she knew and stood up. Her pussy now trying to close itself. She went off the bed and lifted up Billy's legs. She soon wasted no more time in rimming Billy's ass.

This caused Billy to moan. Even though he was blindfolded his eyes were closed enjoying the feeling of being rimmed. After a bit of being rimmed Billy's sister went back onto the bed and put Billy's monster dick into her ass this time. Her eyes rolled in the back of her head as her ass was being stretched out.

Once all of Billy's dick was in her she wasted no time in fucking herself making them moan once again. As she fucked her ass she was rubbing her pussy. It wasn't much longer until she was squirting once again. A few more thrusts from Billy's dick caused him to be on edge. Once Billy's sister squirted again caused Billy to shoot his load into his sister's ass. She soon stood up with a stretched asshole and Billy's cum leaking out of her ass. She soon removed the blindfold and smiled.

"Wow Phoebe that's the best gift."
