I approached my mother-in-law's flat and unlocked the door. I walked in, relocking it behind me. I did a tour of the flat, taking off my jacket as I went. I kicked my shoes to one side, entered the bedroom and stopped dead. My mother-in-law was standing by the bed in her bra and panties, facing the long mirror.
Oh! I'm sorry, I blurted out, I didn't mean to walk in on you.
That's alright love, I don't mind you seeing me in my undies. Actually you can help me. I have this cream to rub into my shoulders and back and I was just wondering how I should manage. Do you mind helping me. I know you may feel a bit awkward.
Not at all, I'm glad to help.
I have to admit that I was feeling a little turned on at the thought of touching my mother-in-law's flesh but I walked over and took the tube of cream from her hand. She blew me a kiss in the mirror and said:
Thank you darling.
She was in matching silk embroidered knickers and bra that were very sexy, and I could feel my penis hardening. I nearly came when she said:
You will have to slide my bra straps down.
