Most the dildo and strap on action in our house was the wife doing me. A couple of times I was allowed to wear the strap on, but she preferred to do things herself.
Hottest times were when she'd use the double headed dildo on herself. I had to kneel by her side and she'd shove one end in my mouth to suck. She'd keep changing ends, so I had a constant taste of her pussy on the head of the dick I was sucking.
She loved keeping me as her little bitch.
