23f here. Was messing around w a bf from a while back and everything was so vanilla. Just missionary and some choking but nothing crazy. He comes back from work all riled up and we get down to it. It just starts with him putting it in missionary and I feel him pounding my insides vigorously as he takes his hard day out on me. Then he tells me to start licking his balls. Not that weird I’ve done that before but he starts pushing my head down to his ass. I start to lick but I’m so conflicted on what to do. He assures me it will be ok and I start going down on him. It was not bad but I’ll never do it again.
