From a few days she was not feeling well so we visited a doctor, the doctor advised us to get some tests done from a pathology lab. The test included ...blood test and x rays of chest. We visited the lab in the afternoon and there was a bit of rush so the pathologist just took the blood samples and asked us to come later at 4pm to do the x ray. I saw a wicked look in his eyes and knew something’s going to take place. I had a meeting so it was not possible for me to take Mona to the lab afterwards. “Oh God! We forgot to use condom”, i told her nervously. She smiled and pulled my head to her melon sized breast.”relax. Your slutty sister takes care of everything. I am on pills” she told me as i began to suck her tit while mauling the other. I fucked her once more in doggy style and then we freshened up and dressed few minutes before mom came home.We were dressed up and watching TV like any normal brother and sister when mom came home. She changed up, got busy in kitchen.Ankita whispered in. As we entered the bar area my boyfriend told me to go stand by the bar and wait , he held my arm for a second and kissed me , his hand slid up my dress to my knickers and he snapped the elastic , my knickers hung around my upper thigh . I looked at him shocked at what he had just done , he smiled and said I looked much better for him now and I wouldn’t need them . I stepped out of them and left them on the filthy floor not actually wanting to bend and pick them up now. I went to the bar and. I flick my wet little tongue around, then blow on the head. I lick the length of your long shaft, paying special attention to the sensitive underside, (I aim to please) and arrive back at the head, gently pressing at the tip, before placing it into my warm, welcoming mouth. My tongue swirls around, my saliva getting you nicely slicked and warm. I slip you out, and gently blow again. Then replace my mouth, wrapping my lips tightly around your thickness, as I tenderly begin to suck. One hand.
