Because our mum Jenny is really our step brother James who married our dad as a cross dresser and now they live happily and me and my brother/sister a...d now cross dressers to this part of the story is where we have sex with our teachers and parents.It all started when me and Bobby/Beth where next door neighbors and yes we know each before we went to the orphanage and are real mums and dads were best friends from school and they had me and Bobby on the same date and so this how me and Bobby. It was like someone had hit me with a sledge hammer; it was so strong and sudden."As she talked my eyes were riveted to her beautiful breasts. Much larger than mine, hers were atleast a D cup and hung like melons. Her nipples were a chocolate brown not a dusky pink as you would expect but chocolate brown with large areolas. My hands reached for them, here I gently tweaked at each nipple before attempting to take a whole breast in my hands. They felt so soft."I love your breasts, Cat. Just. Then I had a crazy thought. I could strip down and watch Geri in the nude and she still wouldn’t know! So, before I could change my mind I pulled off my tank top and dropped my shorts to the ground and stepped out of them. I grabbed my cock and started stroking it while I moved to the center of the window and just masturbated while looking at Geri and her fine little tits! It was so fucking awesome to be nude out in public and masturbating while my friend was just a few feet away totally. Nind bhi nahi aa rahi. Kuch der mere sath aa k baithoge? Maine kaha haan kyo nahi maamiji. Maamiji muskura ke boli garmi bahot hai aur iss kamre mein cooler bhi nahi hai. Chalo mere kamre mein chalke baithte hai aur hum dono unke kamre me chal diye. Kamre me jaate jaate maamiji ne ghar ka main gate andar se band kar diya aur mujhe le ke unke kamre me chal di Main unke kamre me bed ke paas padi ek kursi pe baith gaya aur maaiji apne bed pe let gayi. Unhone night gown pehna hua tha. Phir wo boli.
