I'm a school dropout, and my cute, cheeky, big-breasted senior saw me riding my electric scooter home. She found out I was a virgin, and while examining my huge cock, she showed me her pussy, saying, "This is where you put it!" I was so shocked by the sensation I felt for the first time that I got a full erection! I knew I shouldn't put it in, but when I practiced with her, it slipped right out and I was like, "Ah! It went in!"
