I must admit that with little that my sister-in-law does I fall surrendered at her feet. When she gets slutty (which is almost always) she gives me a hard-on because she is also very sensual as well as sexual. As soon as she gets out of the shower she starts slutting around while I watch her silently pounding my cock. I immediately have to stop because otherwise I would cum just watching her. Her ass is amazing and when she rides me I can’t describe what I feel, plus she measures the time perfectly to hurry up the fuck. My asshole brother doesn’t know what he’s missing because he hasn’t had sex with her in months, so someone has to give her what she needs and that’s me.
