Masturbation

"Wow, so big!" Sarah managed to say, while she continued to be transfixed on Adam stroking his massive tool.

Both Sarah's and Amy's hands had found the way under their skirts, a wetness already clearly evident.

"Why did you never mention that your brother has such a huge cock?" Amy uttered, slightly out of breath.

Sarah and Amy were soon furiously masturbating, rubbing their slits through their drenched panties.

"Aah! I did not know!" Sarah managed to reply.

Adam continued to stroke his cock and was slowly approaching climax. He had been already very horny before his sister and Amy arrived. Watching them masturbate, unable to resist his cock, was so hot. He remembered the pamphlet: "Intoxicating and addictive quality to their semen."

The fact that they were helpless and succumbed to instinct just by watching his cock was invigorating.

• Amy, his sisters hot friend, cheer-leading co-captain, could not resist.
• The boys in the shower could not resist.
• His gorgeous sister, cheer-leading captain, envy of all the boys in high school. His sister, who should be taboo. Even his sister could not resist.

With these thoughts Adam moved closer to the girls.
