The Two Aliens are revealed

Samantha watched as the curtains where pulled to the side reveling two enclosed tanks.

Inside the one on the right was a 4 foot long cock with basketball size balls, it was throbbing and wiggling around the tank, the tip was drooling a clear ooze.

the tank on the left held a normal nude man he was sitting on his bum on the floor of the tank, he was muscled like a body builder but sexy like a male porn star, he also had what was in the tank on the right on his crouch, the same size cock with balls, it was like he was holding the thing in his lap.

"Students, the Alien's look exactly like us, the only difference is that they have these half meter cocks attached to them, pay attention to there balls, the bigger balls more efficient for breading, dont be fooled by there calm look, these guys have an insane sexual urge, and the alien penis alone is worse" said the teacher.

"oh, i would love to try that cock, what an orgasm that would bring." whispered Crystal to Samantha.

"Unless your orgasms comes from getting bloated like an alien breeding bubble....i will explain" said the teacher who had heard crystal whispering.

"some scientist claim that these where humans before the alien monster cock domination, changing there mind and DNA, they are vicious infectious cretures designed for mass breeding"

The teacher paused for a sec as two men where bringing a woman in the the room, the woman was wearing only her bra and panties.

"now class, we are going to show you what happens when you come into contact with the aliens, this woman had been in prison for life, in exchange for freedom, she will be our test subject for this class" said the teacher as the woman was dropped into the tank with the nude man with the alien penis.
