Ronnie shifted her butt slightly and that was enough to make my pussy wet. We cheersed to our last semester and took our last shot. Ronnie stood up an... said she was going to check her make up one last time. As she neared the doorway of the bathroom she looked over in my direction and nodded for me to follow her, which of course I did. Even with the “liquid courage” I still had butterflies in my stomach. When I walked into the bathroom I shut the door behind me, took a deep breath, and went for. “Mom, he is dressed. Don’t you want to be comfortable Manny?”Mrs. Dvorak addresses me, “These children are open. I was going to see if you wanted to take off clothes. Sorry.”“Oh sure.” I then try to nonchalantly take off my shirt, pants with the belt in it and then briefs. The briefs had dried from some water that was on the bench in the locker room. I hand my clothes to the mother. I note my cock is partially stiff pointing down at a 45 degree angle. I am glad I am no longer so young or it. “Are you ready?” I asked, knowing full well he was.I pulled my panties to the side, grabbed his cock and guided him, so he lined up with my wet and wanting hole. He thrust his hips up, pushing himself in deeper, but I wanted the control. ”Just…” I lowered myself onto him and moaned. He slapped my ass gently and grabbed hold of my hips. I began to slowly grind on his cock. He sucked on my tits again, as I ground on him. He slapped my ass a few more times, encouraging me to go harder. I obliged. The ache in his balls grew but it was nothing compared to the sharp pain of the spikes that were once again going to work on his shaft.Mike explored his Mistress' ass with passion, kissing, licking, and probing her hole with his tongue. It wasn't too long before Mistress Jacqueline was about to reach her first orgasm. She reached behind, pulling his face hard into her ass, writhing and thrusting against his face as her orgasm exploded. At this point Mike was in agony, the spikes were digging.
