My girlfriend once admitted her biggest cock she ever experienced was her friends bisexual brother who had nine inches of thick beef. She said they were young and they were bored at his parents log cabin.
She said she had no idea he was actually bi until they had sex a few times and she was disappointed because she fell hard for him and her then boyfriend was average at best and they made love and he was actually a better lover than anyone she’s ever had. She said the sex was intense and very very pleasuring.
