Guy surprises us in the shower - blowjob threesome!

My girlfriend and I have just had a shower and some bloke comes in... We didn't realise it was a mixed shower. But the sight of our nude bodies turns him on straight away and of course the hard cock immediately gives us ideas! We grab the guy, blowjob his cock and fingering and licking each other in between. In the end, he cums in my mouth after I've sucked his balls.
