2 Reasons.

My legs hurts. There are 2 reasons for it: 1) too long cardio in the gym; 2) too long riding position on my BF's cock. Yesterday we skipped the gym, because the weather was so beautiful and we had a nice walk with ice cream, shopping, drinking beer and so on (it was a very nice afternoon). As for the riding - I don't have to explain. I don't need a reason for it. :) My BF was so thick today, you have no idea! He told me he had a naughty dream during his nap, so he was REALLY horny... and big! This was the right time to surprise him - I was naked and fresh-showered. It was an excellent fuck. As usual. But now my legs hurt. But who cares... :)
