Wife's Dad would spank her

So wife told me her dad used to spank her for as long as she could remember.

She said he would tell her he was going to spank her and tell her to go and wait for him to come upstairs. He would then drink some scotch then go into the room and have her lay over his knee. He would have her pull down her panties, lie over his knee as he would talk to her and she would wait for his spanking with her panties off and his hand resting on her ass. She said her arms were between his legs kind of resting in and around his crotch.

When he would slap her bottom, she would kind of squeeze his legs with her fingers and she said she could feel his cock twitch against her stomach. With each slap of her bottom she said his cock would grow and she could feel it get hard. She said feeling his hand on her ass and waiting for him to slap her was one of the most erotic things she had experienced growing up.

She said she could feel his cock growing hard as he spanked her. At first she felt it on her forearm as she lay across his lap. Soon she started to reposition herself so his hand was on his upper thigh and as his cock grew hard she could feel it and, eventually, she started to squeeze his cock and hold it in her hand.

She said she began to position herself so her legs were spread slightly and, when he would rest his hand on her ass, she would try to open her legs more so his fingers found her pussy. He then began to spank her, slide his fingers into her pussy and she said she could feel herself getting wet.
