we were so close

my boyfriend and i were taking a shower yesterday... separately but still in the same room... and as soon as I came out of the shower and wrapped the towel around me, he got up and climbed into the bathtub with me, pinning me against the wall. he was kissing me all over and once he got to the base of my neck, we got cock blocked... he sister's boyfriend comes knocking on the door and we had to hurry out of there acting like nothing was going on. we lost the mood for quite a while after that...
