For years i saw my 52 yr old foster mom drying after bathing.When we were alone the door was open which any 15 yr old would enjoy.She was 5 ft ish but had a good full firm body and naturally this aroused me s******* which she was fully aware of.She briefly mentioned s** education to me one day but that was it.One day it all got too much so i walked in on her wearing jeans etc asking if she wanted her back dried,my heart was pounding.When she said yes son i was trembling with excitement.As i started she turned and said do you want to get naked so she watched me as i stripped and paid me compliments lets say.I moved in behind her and our bodies then became joined i suppose and then things started to happen with me rubbing myself all over her hips / back.She told me its ok son and turned round.She then stroked my manhood and instructed me how to pleasure her.I felt a beautiful sensation and immediately wrapped my body round hers, then we were drenched in each others body fluid.We both embraced and i felt her lovely lily white hips.She then walked away and i hadnt a clue.Slowly i walked out and looked in her bedroom where i found her lying face down beckoning me.This was my first time with a woman and she guided me gently inside her telling me to push and enjoy son so i did.Her hips were quivering and the slapping sound was awesome.She taught me everything that day and we continued to have full unprotected s** until she was 68.
