Perhaps the quickest player in the squad, he marked his debut in the Guinness Premiership last season with a try at Welford Road against the Leicester Tigers and has scored four tries in just 108 minutes of Amlin Challenge Cup rugby this season including one last Saturday in Italy against Rovigo.
He told the club website that signing his new deal is a huge weight off his mind and he's looking forward to his future with Gloucester Rugby.
"It's nice to get it all cleared up so I can just concentrate on the rest of the season. Players will be going away on Six Nations international duty so there's a good opportunity for me to play a part."
"It's a really big couple of years for me and I want to focus and work hard so that hopefully by the end of it, I'll be featuring in the first team on a regular basis."
"Gloucester has been a great place to learn my rugby. I've come through the ranks here at Hartpury and Gloucester alongside my best mate Henry Trinder and we've pushed each other the whole way."
"We've also both benefitted from being able to train and play alongside the very best in people like Tins (Mike Tindall) and Eli (Eliota Fuimaono-Sapolu) who have taught us a lot."
May is just one of a number of young guns in the Gloucester back line who have been making their mark at first team level in recent times.
The likes of Freddie Burns, Dave Lewis, Charlie Sharples and Henry Trinder are all good friends off the pitch and May admitted that it's great to be playing first class rugby alongside them.
"Definitely. Hopefully, within the next couple of years, we'll be part of what will be a pretty dangerous young back line and that's exciting for everyone."
Head Coach Bryan Redpath admitted that May is certainly one to watch.
"Jonny has shown exactly what he's capable of when he's had opportunities at first team level. Whether he features on the wing or in the centre, he's had the chance to learn from some of the very best here at Gloucester."
"He's got bags of talent and, with hard work and a continued willingness to learn, he can be a big part of our future here at Kingsholm."
