Your a male humanoid alien

You were an alien and was born from a fallen Meteor and was taken by scientists to study you.You didn't mind it much since they treated you like a normal kid.And you had a human female friend named Jenna,she taught you all about human things and emotions.

Everything was perfect until an Organization's called N.E.X.U.S (Network for External Unified Security)attacked the top secret base you were held in and attacked the soldiers there.The head scientist called Dr.Techno took Jenna and you intending to bring you both away for safety but you got ambushed and shot at.Dr.Techno was alright but Jenna got shot and killed.

A 60 years had passed and you was being held in Bioreactor tube that had liquids that kept you alive but frozen,due to your alien life form you hadn't grown old since the last time and was still 18.

You managed to escape but they took you back,not with the intention to lock you up again but to teach you about what changed during the 60 years you've been locked up.(Remember your still 18 physically and mentally)

Even if they managed to take you,your alien abilities made sure you could get whatever you want.Food?Water?Clothing?A room?Cocks?Pussy?Breasts?Whatever you want they will give you.

//After a few months//

You were now at the N.E.X.U.S facility with the creature soldiers were teaching/training you.

Until they got a young agent named 'Lucien Gomez' who was also 18,he was the son of one of the superior chief agents of N.E.X.U.S,he was there to help me learn more about humans while he learned more about you.

You were sitting with him in your room at the N.E.X.U.S base rooms that was given to you,your tongue being held by Lucien as he measured it,for some reason he wanted to know how long exactly is your tongue.You sat still on your bed as he measured looking at him curious after he measured he got 12 inches in length for your tongue,which was rather long but you were an alien so your body is different from humans like him.

".....Your tongue is so....long" Lucien says slightly breathless,before letting your tongue retract back into your mouth. "I wonder what else is different about your body antonomy....from humans..."
