Big Tit young girlfriend curious about black cock would you fuck her?

Recently my girlfriend has been telling me about her past and certain fantasy’s she has. last night she told me that shes been fantasizing about having sex with a black man so she explored it to see if it was something she’d be interested in (she does know i am somewhat into cuckold lifestyle). there’s a story behind this. she wasn’t interested until she joined a new gym, she was in the sauna when a black guy came in nude. from what she told me, she was laying in the sauna in her bikini when this really good looking black guy came in completely nude he was from the Caribbean so this wasn’t strange to him. he came in and started telling her how beautiful she was, how woman from the Caribbean were nothing like her. She told me he was sweet so she continued talking to him. i asked her to be completely honest with me so i asked "did you get turned on by this guy" she said she couldn’t help it, they had chemistry. she had heard from friends that black guys had big dicks but being so close to such a big one interested her she didn’t know they could get that big she looked at it like a challenge would it fit? how deep could he get inside her? would he make her feel things she never felt before?. it intrigued her then she started telling me at one point he seen her looking at his dick so he said if you stare at me i get to peak at you. apparently without thinking she jumped up and bent over in front of him. when she looked back at him she noticed his big dick getting harder and harder, he asked for a lil more from here she didnt know what to do they had been talking about her piercings earlier so she asked if he wanted to see one of her "hidden" piercings she took off her bikini and showed him her nipples, from here he started jerking off to her. she continued saying she posed for him, rubbing her nipples, slapping her ass, couple minutes in he cummed everywhere! he went up to her, put his arm around her, his dick poking her stomach and said im here everyday lets meet her again and ill make u feel like a real woman. he walked out leaving a little bit of his cum on my girlfriend and her sitting there fantasizing about the next time they meet. Now my question should i let her fuck him, the thought turns me on and the day this happened she came home happier then ever. Would you fuck her? is she black cock worthy? how much could she handle? What do you think of her tits?
