数学の学生ブロンドの報酬

The young man from the neighborhood takes me occasionally tuition, because he had problems in vocational practice. Math did not really suit him, but then it rings at my door and he shows me his last work: 1 in math! For that I promised him a reward and my girlfriend thought the idea was pretty good that the young guy with one horny threesome with two blondes should be surprised! At the age of 19, that was certainly the best reward he could get could imagine!
