Joanna pulls her knees upwards slowly and then even more slowly spreads her knees apart, giving her son his first really unobstructed view of her hair... pussy. As she spreads her knees, she lets her legs slip down forming a diamond at which the top is her cunt. She slides a hand down her thigh, letting her fingers tangle in her bush and then uses one finger to spread out her pussy lips. Joanna is already aroused and it takes very little urging for her labia to flower out, revealing her wet, pink. "Hi, yourself," I replied."Ready for some fun?" he asked."Always," I said with a giggle."Right, put on a pair of thong knics, that wrap around blue skirt that I like and that semi-transparent blouse and I'll pick you up in fifteen minutes," he ordered."Ok," I agreed and giggled again.I rushed to find the things he had mentioned and I was just finishing buttoning up my blouse when he beeped his horn."Hi, babe," he said and leaned over and kissed my exposed neck.His mouth found mine and we kissed. After he got up he told me that both of us are the girls and I smiled and said I liked that and we went to sleep. The next evening at 10pm he gets me to come to our room and he tells me that the guys next door to us Shaun and Jerry are going to screw us so Sam tells me to get naked and so we both strip and we see Shaun and Jerry go into their room and Sam and I turn our backs to them and bang our butts together and we look back and they both smile. We wait a few minutes and then turn the light. I reached underneath my bed and pulled out my other best friend, the dildo which I bought online.I lubed up my fingers and began to finger myself very gently, trying to expand my anus before the entry of my dildo. In between alternating insertions of my fingers, my hand slid up and down my cock which was soaked with my pre-cum at this point. When my anus finally felt relaxed I went ahead and pushed the dildo inside. I let out a loud moan of relief and began to thrust it in and out of my ass.
