Girlfriend first black dildo

I've always had the fantasy of watching my beautiful girlfriend take a big black cock for me. It didn't matter if I was with her or not, the thought of her making love to a black man drove me crazy. She was always a little hesitant after I first brought it up, but we agreed on getting her a black dildo. She's never had a cock bigger than 6 inches and she wasn't used to a thick cock. We ended up getting a 8 inch black dildo even though she was a little freaked out by how big it was. We got home and took a shower together, but I couldn't wait to see her take a black cock for the first time. We quickly moved to the bedroom as she laid on the bed and spread her legs for me... Her pussy was so wet, she was dripping with excitement. I didn't know she was going to be so eager to have the biggest cock in her life. Even though she was soaked, I used a lot of lube on it so it would easily slide inside her. As I slowly inserted the tip inside her she immediately shuttered and screamed, but as I looked at her face she told me she didn't know whether to feel pain or pleasure because it was so big. As I slowly fucked her with it I could see how creamy her pussy was getting as she attempted to take all 8 inches. The more she warmed up to it the more she loved it, the faster I went the more she screamed, and the more her toes curled up as she told me "don't stop!!! don't stop!!".... She ended up squirting for the second time in her life... The morning after she was a little sore, but she thanked me for her new present in the best way possible
