As they were humping he let his fingers slip under the edge of Sandy's panties. Sandy immediately broke the kiss and with labored breathing pleaded, �...�Uh, please... I love the feel of your hands... and you can do anything you want... but please... only on the outside... not under... please.” “I understand,” whispered Bob, “I'm sorry... just got carried away... won't happen again... I respect your wishes and nothing is going to happen... but you are making it hard for me.” Sandy burst out. I felt cool wet skin of her thighs go warm as my sperm pulsed out, each thrust in and out getting warmer and slimier as I came, dribbling down her legs, and for the last cum spurt I pulled out and rammed the head of my cock home inbetween her cheeks. Were it not for a thin cotton layer of shorts I would have cum in her asshole. I felt the last gush go into her crack, and then slime around the head of my cock.As I regained composure I realised she had stopped enjoying the show lol. She turned. Then I heard her breathing. Heavy. Passionate. My toes curled as I whimpered. I heard a gasp bleeding through the walls and knew Rebecca was experiencing this same anticipatory delight. Hot breath caressed my shaved pussy folds. My dick twitched.“Oh, my god!” I gasped as wet lips kissed my inner thigh an inch below where my leg met my groin. Silky hair brushed the lips of my excited pussy. “Who are you!”The woman didn't answer with words. She just kissed up my leg, coming closer and closer to. Then he kissed me again as well.“I love you too Lisa, more than a step mom,” Tim said.Then we both just felt the spark come, and both started moaning really loudly.“Holy shit, I'm gonna explode now Tim,” I said.“Me too Lisa, damn you are the best step mom there is,” Tim replied.We both had big orgasms and mine was the biggest I had in years besides the one I had a few minutes ago. Then we cuddled for a few minutes and tried to comprehend what just happened.“Wow Lisa, you are a very sexual.
