Finger's first. Gradually lead to some meaty dirk

Jack was programmed to never have such thoughts. But the curious side of him silently goaded him forth. He was on a new world, learning. What better time to try, when one is by their self. Better off, than some strange person. This seemed to steel his conviction.

Staring ahead, Jack snaked his arm around to his backside. He could feel his finger enter his virgin back door. Just inches in, he loosened up the muscles he didn't know he was clenching. That seem to make things easier.

He couldn't believe he was doing this...

For being a rookie, he quickly had his whole hand entrenched. The feeling was "unique". Not something that he wanted to emulate with anyone else. But this got him to thinking...

Looking at his cock,with its 13 inch length and 5 inch width diameter, Jack thought about the idea of trying... Removing his hand, there was a feeling of loss. "Fuck! What did I just do!"

"What have I told you about cursing young man?"

God knows when, but his mother had turned up behind him. Her arms were folded beneath her huge milk-bearers. She almost made them obscure her vision. Looks like she had been watching his antics for some time.

"Now I know you want to learn about how your body performs, but just remember me and your father are here to help." Unfolding her arms, she came up beside him to wash her hands.

With a gentle bump of her hips, she scooted Jack to the wayside. This staggered him a few steps behind her.

Jack was left to his devices; not sure whether to stay or leave. He wanted to have a shower, but his mother looked like she had something to say. After 30 long seconds, the sound of water and soap mixing ended.

"Now Jack, I know it's a bit to get used to, especially all of a sudden. But in time to come, you'll come to find that what you've known before was all wrong."

Making sure to check he was listening, she cupped her tits and fondled them in comfort. It was like she had been holding back all this time.

" You'll find things strange at first. Just like that thing between your legs that's leaking non-stop." With a smile, and a nonchalant tweek of her nipples, she continues. " Even when you were testing things before. You should learn to follow your urges whenever they arise."

At this she pauses. Taking the time, she turns and looks at Jack. Looking into his disbelieving eyes she finishes. " But remember. When people say no, they mean no. Just as on earth, okay?"

Jack wanted to point out, that she said not to follow earth's customs previously, but now to follow one of them. But he knew she was right. It's just... his cheeky side wanted to throw his mother a funny quip. It was his way to lighten the mood.

"Okay..." Jack agreed. Seeing her round backside and huge knockers, kicked his cum production into overdrive. It was leaking torrents.

"Great! Let's have a bath shall we?" Grabbing his wrist, she guided him into the tub before sitting in front of him.

Sitting there, with his cock pointing to the sky, lubricated and waiting, he watched his mother grab the sides of the tub and sit down. Two gentle sighs rang out, one in relaxation and the other pleasure.

Jack marveled at the feeling of his cock, teasing her slit and back door to rest on her backside.
