Like a good girl would of course.

Of course despite his hardness he would not christen in this new sexy body by playing with his little excuse for a cock. In fact why not remove the temptation alltogether:

(+Can only cum from anal stimulation.)

He touched his little cock one last time feeling the pleasure rise. Ohh his cock was absolutely useless now, he was just a sexy set of holes... And while at it why not improve them.

(+Self lubricating asshole)(+hyper sensitive ass and throat)

Immediately he could feel the soft fabric of his panties feeling uncomforable around his rump. As he slid them off over his enlarged posterior, a surge of pleasure rushed through him. His asshole felt so empty all of a sudden, greedy and wanting. He needed to fill it right now!

(+Anal Masturbation)(+Huge black dildo)

As reality shifted aroudn him he felt something pressing against his tight asshole. He was not entirely naked, his useless dick hard hanging limply there while his asshole felt almsot throbbing for what was beneath him. He needed to, he needed to be filled. In a quick slam he thrusted down onto the fake cock ramming half of it into his needy body.

"Fuuuuuck ngggghhh, too much!"

He tried to get of it but every inch of movement flooded his mind like nothing before. Girly moans flooded the room, he was not holding back and he could not. He was quickly thinking of using the app to get off but isntead took some deep breaths.

"Be a good girl alex, you can take it. Ohhh fuuuuuu..."

Slowly he lowered his hips further taking more and more of this behemoth of a dildo.
"Be a good...ngghhgg... good girl..."
He kept reaffirming himself, reminding him that this was what he wanted. And damn it felt good. The juices his Asshole was producing rand down the invader as he finally managed to bottom out.

"Yes..."

As he looked down he could see the bulge up to his ribcage this faux cock was making. Ohh he was so slutty, takign such a thing on the first try. He rested a hand on the bulge feelig the hard plastic beneath his skin. Then he took his strenght together and raised his ass. The nerve ending through his whole body were so sensitive, he could feel every inch of it moving within him.

The wet sound echoed through the room as Alex slammed his hips down.

"So goood!"

His eyes rolled into his back and once more.**

Then again.

"Alex What the fuck!"

"Jess?"
Alex was thrown out of hislust filled trance as he saw his younger sister standing in the door to his room. Before even gettign off the dildo he grabbed his phone and took a picture of her. Freezing her into place as the prompt appeared.
