Threesome With My BF's Stepmom

My boyfriend FINALLY invited me over for dinner with his stepmom! I've been nervous to meet her, knowing they're very close, and she's just beautiful. I actually think we kinda look similar?

Unfortunately, his dad couldn't make it, so it was just the three of us. His stepmom started telling me that she and my BF had even discussed how we resemble each other... though he looked a bit embarrassed.

After dinner, my BF and I were joking around, trying to get him to call me 'Mommy' (as a joke!), when his stepmom thought we were addressing her!
