When I got home from work I found my step-mother Lily in the kitchen doing dishes. We made some small talk then I ask where my wife and baby were, she told me they had went up stair to lay down for a rest. I realized I had another opportunity for some naughty fun. I told lily I was going to go into my room to relax after a long day of work and before dinner. I told her I needed to relax like yesterday and I could use her help of she was willing. She gave me a naughty grin then told me to go get comfortable and she would be in in a few minutes. A couple of minutes later I was laying naked on the bed I shared with my wife stroking my cock when my wife's step-mother walked in! her eyes locked on my rock hard cock as she walked over and got up on to the bed between my legs. I asked her if she could lend a hand and she did. I spend the next little while getting jerked of by my wife's step-mother while she was upstairs resting with our newborn!
