I took viagra by mistake, and asked my stepmother for help.

I had a lot of headache, I went to my stepfather's pill box and took a blue pill, 30 minutes later I had my dick bursting and a lot of pain in the balls, I went to my stepmother then we found out that I had taken viagra, she said she could help me but it would have to be a secret just for us, And it would also have to be without a condom because she has allergies, so we started it was the best fuck of my life.
