I think if 22 year old janitor had sex with a girl under the age of 16 years then it doesnt matter as to whether she gave him consent, it's still classed as rape (well over in England it is) so for him to get away with it they must've been 16+. If the girls were that old then it sound like they're just seeking for some attention and trying to get him into trouble, maybe because they're jelous, feel used or just bored and attention seeking type of girls. Either way i hope you and your mates are fully aware of keeping out his car!
