Jessica Robbin & Mouna Leesa in Sister wants help teaching her friend

My sister Jessica has an odd request for me. It seems her friend Mouna has never handled a cock ever before and Jessica wants me to offer mine. I’m not really comfortable but Jessica and her friend are so cute and sexy in their bra nad panties, and I know how nervous they are, I go ahead and play along, not expecting that Jessica would give her HANDS ON training, I don’t know how to react to my sister stroking my dick and taking turns letting Mouna try it, but its too late to back out. I try to hold out so Mouna gets a good lesson but I erupt in the middle of them talking, and my sister barely moves in time to avoid a massive facial. As it is she is the one that ends up with my load all over her, but the girls laugh abut it so I know it’s ok
