My sister-in-law, a super slut nicknamed the virgin killer, has been trying to take my chastity ever since she found out I was a virgin, but I'm a masturbator master and I prefer masturbators to real pussies! When she found out, she said, "Compare which feels better, the real thing or the toy!" and forced me to alternate between the masturbator and her pussy in the cowgirl position. Her grinding cowgirl position, showing off her true slutty side, felt so good I came inside her in seconds... "The real thing feels better, doesn't it?" she said, and made me cum many times after that...
