When she drunk she so wild she put her hand on my pants and slowly moving around my cock few times I move her hand but i see she wants more. My gf and her sister start speaking about sex how they like everything and etc. For me was little weird but I like to hear every detail. Her sister told us she loves to use dildo and watch porno because her husband don’t fuck her so much. My gf go close to her and told her something then she go upstairs.
