Finish what we started step son HD

My step-son Mathew keeps insisting that we keep on with this taboo affair that we have together, but as his step-mother, I must be responsible and avoid any more temptations. but his cock is just so big and thick, it feels like heaven when inside, fully spreading me wide open just like when I was a young virgin and I had a tight little pussy. I can’t blame my husband for not trying but His step-father just isn’t BIG enough like my step-son, he sure got his massive cock from my husband.
