He Fucked Her Five Times That Night

Talking about our past one night, I asked my wife what was the most sexual naughty thing that she had done with a previous lover.
I was her 15th lover and she was my 10th before getting together.
She said that she spent the night with one guy and he fucked her five times.
But he didn’t cum five times, each session lasted ages and he kept bringing her to a near climax before slowing down.
She said it seemed like his cock was inside her for most of the night!
Only on the fifth time of fucking her did he shoot his load into her!
She said that he also liked her on top, but she admitted that she was never very good at this position with lovers.
She said she didn’t suck him off.. I don’t believe her on that one as she previously told me that she did give blow jobs to most of the guys that had her before me.
She said that her c**t ( my word not hers) was quite sore the next day, and her thighs felt a bruised!
But what worries me is that she said that she climaxed three times with him.
I struggle to get her to cum if honest.
Now I am worried that she has experienced a better lover with a bigger cock than mine!
