A 21 years old boy is accused of child abuse happened 14/16years ago.

Two girls (22&25 years old) accused a boy of 21 years old of abusing them when they were b/w 6-8 & 9-11 years of age respectively & the boy himself was b/w 5 to 7 years of age(not sure about the age & no proof is there). Now, the boy is saying that he really can't remember his exact age when it happened but he can remember those dark things that happened, he was not aware of those things at all, was innocent & he got involved in this by assuming that some kind of secret game because a cousin brother (was 14-16 years old) of his influenced, groomed him like that; showed porn movies, asked to suck his dick, told him to guard when he & his cousin sister (who is 25 years old now & accusing) were doing sex, because of that he also acted accordingly but he can't remember exactly about any intercourse because he thinks, he was not physically that much developed to do that & he is very guilty for his past mistakes & he thinks he got abused. Sir/mam, what could maximum happen in this case?
