My Step-Son Got Too Excited

Dear Susan, I can't believe I never told you this but the other day my step-son came to me and I showed him how a girl should suck his cock and how he is supposed to eat a girls pussy properly. My step-son must have gotten to excited and almost came inside me within seconds. He apologized but i assured him it was ok because that just means i have another chance with him later tonight. Xo
