Kyle turned and saw that he had hit the jackpot. Joe was totally nude while Tyler was wearing a white jock with an athletic cup.
"Quit talking about my sons. Whatever you're doing, leave them out of this." Jake said, his face reddening as he continued to jack his big cock.
"I don't think a teacher pumping his dick in front of his students is really in a position to make demands. Now why don't you ask your boys to come up front."
"Boys do as he says." Jake said. Punctuating his statement with either a whimper of a moan as he continued to stroke.
His sons didn't budge. Kyle realized that he needed to use force to get control of the situation.
He moved closer to Jake and grabbed one of his fuzzy nuts.
"Take your seat at the front of the room or I'll destroy one of his family jewels." He began to firmly squeeze the testicle. Mr. Smith let out a loud yelp but continued jerking.
The two friends, now brothers got up and moved their chairs next to their father. Their athletic bodies on full display excited Kyle.
He released the testicle and stood in front of the three men.
Jake came. Drenching a 3 foot area in front of him with ropes of cum. His sons blushed seeing their father in such a state of distress.
"17 year old twins and their 16 year old brother at thirty. It must have been hard with no mothers in the picture."
Mr. Smith just looked at him.
"You don't know anything about my life." He snarled.
"Maybe I don't but I can see your genes are strong. It looks like you passed on your impressive package down to Tyler. While Joe only got your balls."
This was a stretch but he saw that what he said about gene expression about Jake did seem to trickle down to his newly attained offspring.
Tyler's cock and balls expanded pushing his athletic supporter while Joe's cock was now dwarfed by his massive nuts. Both guys broadened their sitting posture to accommodate their enhanced packages.
