It started shortly after my dad was gone. Cindy would walk around the house just wearing a large t-shirt and her undies most of the time. She acted all normal but it was hard for me to hide the fact I was hard all the time, pun intended. Seeing her bubble but and sexy long legs made me want to masturbate right then and there, which I couldn't, but it meant a lot of trips to the toilet during the day. One day, she got out of the shower just wrapped around in a small towel that barely covered her privates. I was seating on the couch and saw her walk to my dad's room and I was instantly hard. She left the door of the room slightly open, and could see her reflection on the mirror of their closet. She was brushing and drying her hair when her towel suddenly fell leaving her pussy and boobs visible to me through the mirror. She had perfect breasts , firm and medium size and a fully shaven pussy.
I knew it was risky but I couldn't help but pull my cock out and start stroking it as I kept looking to her reflection. She didn't seem to notice and continued to do her hair. Suddenly, she moved and I couldn't see her reflection anymore, the door of the room fully opened and Cindy appeared standing in the middle. It was so sudden than I was caught with my cock in my hand, there was no denying what I was doing. Before I could say any excuse, Cindy walked towards me smiling and asked me if I needed help. I was too shocked to reply, but she smiled again and sat next to me, grabbed my cock and started to slowly move her hand up and down. I couldn't believe what was happening, her hands were so soft, the way she was stroking me was gonna make me cum so fast, I could feel the pressure building up in my testicles.
Cindy looked at me and without saying anything she bend down and kissed the tip of my cock. The feeling of her lips made me shake of pleasure, she smiled and slowly started licking the head of my dick, I was in ecstasy. After a few licks, she took it all in her mouth and started sucking on it, I was ready to burst and knew I was not gonna last much longer. Right when I was about to tell her I was about to cum, she decided to take the full length of my cock all inside her throat. That was it, this drove me over the edge and my dick exploded inside her mouth. I pulled out immediately fearing she would be upset for not warning her, but she looked at me, swallowed, and took my cock back in her mouth to clean every bit of cum that was left. Once she was done, she winked at me, kissed the tip of my cock and went back to her room.
I didn't know what to do, I couldn't believe what had happened. I should have probably followed her, or at least said something, but I didn't. The following day, I was afraid things would be awkward, but she acted normal like if nothing had happened, so I did the same. A couple of days passed and I thought it had just been a one time thing when one night I heard Cindy moaning and calling my name asking me for help.
At first I thought she was in pain, that something might had happened to her, so I went to her room and knocked asking if she was ok. She immediately replied saying she needed my help and to come in, she sounded out of breath, and it seemed she was having difficulties breathing. I rushed in worried that something could be wrong with her, but what I saw left me speechless. Cindy was laying down in the bed fully naked, her left hand was caressing one of her nipples while the right one was busy with her pussy. She looked at me with pleading eyes and said: "I need you to repay me the favor now, please..."
