I always wanted to cum in her mouth but my mother never let me, she told me she didn't like it but this time she proposed an exchange, she would let me cum in her mouth if I would let her fuck me in the ass with her strapon. I looked at th size of it and I was a bit scared but I wanted so much o fill up her mouth that I agreed. I got so excited with the ideia that I delivered such a huge load that she gagged then came the hardest part, but I don't regret it.
