It seems that you have missed their sex session in the guest room around 8 o'clock their time.
He has fucked her during more than 16 minutes and she has even tried a little bit of anal. And then, he has continued by licking and fingering her pussy during another 6 minutes. At this time, it's her who has asked him to stop because she coudn't handle it anymore.
And I don't even speak about their previous session around 1 o'clock their time in the bathroom for another 19 minutes.
I wouldn't call this being the worst lover ;)
Or I guess that a lot of us would have to be considered also as very bad lovers 8)
PS : And they are at it again right now ...
