Pizza boy tickled

When Matteo orders pizza, he finds a young naive Latino delivery boy right in his living room. So when he catches Chris eyeing his new tickle torment device, he offers the straight jock a chance to earn his tip: Chris just needs to let himself get tickled. Easy. But there's a catch: if the greedy young man laughs, Matteo will take off one piece of clothing from him. And this pizza boy is so pathetically ticklish - even through his polo shirt and white dirty socks - that he is screaming "No more!" not even five minutes in! Chris' clothes keep coming off, his ticklish soles are fully exposed and Matteo has just found out the balls are his weakest spot. It's so pitiful that Matteo decides to up the game: what can he do next to give the youngster one last chance before making him crash out?
