My wife Barbara is 5ft2tall slim with 36dd breasts of which she is very proud. She was a virgin when I met her but over the years has grown to love sex. We belong to a local swingers group and up to now how only swopped with other couples ,but at our last meeting in a local pub we both got very drunk ,and she got into a conversation with two very good looking black guys and their partners. We all got on very well and when the pub closed we invited them back to our house for more drinks. We played a game of strip poker and Barbara was soon down to a very small thong ,and Wayne one of the black guys down to nothing at all. His cock was enormous and I could see Barbara admiring it finally taking it in her hand and sucking it, Wayne was soon removing her clothes and she stood there with her waxed vagina and 36dd breasts in full view. I am not sure what happened but Wayne and his friend had taken her upstairs and were fucking her in our bed. They were soon joined by two other white guys . I tried to fuck her but her pussy was so stretched she couldn't feel me. Since that date sex for me has been a no go area. Having enjoyed big cocks my 6 inches is no longer enough for herAny suggestions what I can do?
