My step-daughter is so straight laced & boring, it's no wonder she can't get or keep a boyfriend. I am at the pub with her to meet her latest conquest. There is an instant attraction between us and so later I meet him in the pub toilets for a sneaky blow job! Eventually all three of us make it back home and he & I manage to persuade her to finally let her hair down & get naughty. A filthy threesome ensues... until I let it slip about what happened earlier at the pub!
