Since junior school in 60s i would spy on my religious adopted mom washing at sink.She was 48 full figured,wore corsets and bra but no knickers.As i turned 15 my arousals were unbearable so one day i slipped off my shorts and walked in behind her.I started to massage her back while rubbing my throbbing c*** up and down her bottom.She said oh son thats lovely and its normal for you to be excited you know.Within seconds i came all over her hips and corset.I apologized but she said dont be silly its all right.This went on for weeks until one day she removed her corset and bra while i was massaging her,and turned round.Her breasts were big and firm and her p**** was really hairy.I wasnt experienced but we hugged and felt each other.She showed me how to finger her so i placed my other hand on her hips while she wanked me off.She grabbed me tightly as she came and i spunked right up in the air over her breasts.Thats better son isnt it she said as she cleaned up.Nothing more was mentioned until one morning later when we were alone in the kitchen she said i will lock the door and we can go to bed for a few hours.That morning was wild as we got into bed naked and her teaching me oral.Everything fell into place and i gave her a good f****** regularly for years.
