"Hey Dustin"
Dustin turned around, "What? You aren't going back on the deal already, are you?"
"No...just wondering if you were keen to make another. I know you have been hitting the gym, getting in shape for the rugby season. Probably trying to catch the eye of some girl? Well I could give you a little help with that, for a little something in return."
Dustin looked back with a skeptical glare, "What did you want?"
"A blow job. Get on your knees and blow me. The better the job, the more I will cum and the bigger you will get."
"Fuck off Ty. No way."
"Seriously? For little effort I could make you as fit as an Olympic athlete. You could get to the top of any sports career you could want. You don't have to be grossed out by it. I can make you like it if you want."
Dustin pondered this for a moment, "You better not tell anyone."
Ty dropped the towel and grabbed the base of his big cock as if offering it to Dustin. His foster-brother came over, paused, then got on his knees.
"Not a word, Ty"
And then he put the cock in his mouth.
