Well I did a few days ago lol...It was the first time we had sex together and yeah things were going great and all, I came, she came and on to round 2 after 5-10min break

So i turn her around and doggy her for like 20 mins and flip over to do some missionary for 10 and then she rode me (5-10 mins)and eventually she came quite hard (could feel the contractions and all...I still didn't so i gave her a moment after her O) and proceeded to my big O # 2. So then she whispers into my ear that I'm getting a little sore down there lol...

At that point I just told her well how bout some oral finish and she gave me head for about 10 mins and just settled on jacking me off instead

Is there anyway I could increase her stamina? Cuz to be honest I don't think I was anywhere near cumming on my 2nd round and I probably could've gone doggy for another 30mins before climaxing when she said she started feeling sore.

Thanks for any advice.
