My older sister was a bbw. the night our parents went out. I was 13 dhe was 17. Well she caught me jerking off. She ask me to come to her room. She asked if ive ever felt the inside of a woman. Being a virgin i sure didnt. Well she must have been super horny because she asked if i would like to try. Well i couldnt get it in so she guided me in. It was amazing the feeling i was all the way inside her and had two pumps in then she stoped me. I never forgot that feeling. I wanted more. So the next say she went on the pill a week after i fucked her and blew my load inside her.
