As I felt her breast and nipples, I knew they would be perfect to look at when riding me. I can just picture her mouth open panting, bouncing on my rock hard cock.

As I went home, took a hot shower and stroked. “See…we could easy have bee….” “Suck it” “Nooo...not here…not now” “The sooner you get on your knees the sooner you can get back off them” With a loud sigh and resigned to her situation, Mum sank to her knees and took my erect cock in her mouth, eagerly sucking hoping to make me cum quickly before Mrs Noakes came back down. I was rather surprised how easy it was to make my mother do as I ask.We heard two pairs of feet come thundering down the stairs. Mum tried to get up but I held her head. My grandpa is not a very talkative person; mom did not seem to notice anything. She was occasionally busy with her routine chat with grandma.The only person who was restless throughout the journey was I.

I loved to see her fucking other guys and I was eagerly looking forward for the another opportunity.We were not in.
