The youths, all either 16 or 17 years old, were the subject of a recent investigation by officers from the Met's Child Exploitation Team.
The investigation relates to allegations made by a 13-year-old girl about two offences, one in Tower Hamlets and one in Hayes, Middlesex, which occurred on 6/7 September and 21 September.
Two of the boys have now been charged but cannot be named for legal reasons with the remaining six on police bail pending further inquiries.
