My very first blow job came from my sister. She and i were alone one summer day. I was in our basement watching a porn and jerking off. She snuck down there and caught me. She asked me what i was doing so i told her. She asked me if she could touch my hard cock and i told her she could but only if she would let me touch her pussy. She eventually agreed after we both swore to secrecy. Since i was already nude, i let her go first. She played with my cock with both of her hands admiring its size. I coached her how to stroke it properly. While she performed on me, i slid off her pants and underwear. I rubbed her young pussy and fingered her tight hole. She got wet and was aroused. I got on top of her with little resistance. She asked me if we would get caught but i didnt care
