Intoxicated wife

Would love to know your thoughts on this my wife recently went away on a running trip with our club at the function after she apparently got very inebriated she is a real lightweight drinker anyway young James who is 18 seems to have taken advantage of the situation she tells me she went back to her room James followed her there and went in with her she said as soon as the door was shut he was furiously undressing her she said it was a real blur before she knew it he was on top of her spreading her legs and mounting her furiously she said she fell asleep after that but during the night felt him touching her around her vagina and breasts she said that led to him mounting her again but this time she came as well anyway under the morning she quietly got out of the room and showered apparently heard her and came into join her she tells me he held her firmly against the wall as he mounted her from behind for a third time but while he was thrashing her his cock slid into her ass she said it was very painful but he wouldn't stop until he came inside here again the thing is we see him quite often at the club I've only just found out this has happened he is one of the young guys I run with and my wife still seems to be quite friendly with him although quite embarrassed she is 48 and I am 53 I've shared this elsewhere but really want to know your thoughts
