What is the value of an experiment? Let's be straight, I mean sex. To fuck. Everyone does it. Whether in public or private. Grimace or daring. Solo, in pairs or in groups. And, in practice, it is a combination of everything already quoted. It is not science. It's just being. I'm leaning against the wall, my dick and back hurts. I do not get out of this position as I feel my cock sink deeper every second as you increase the back and forth movement. I feel my body warm and soaked with sweat. Until we reach a frenetic pace and an act of almost mercy to our weary bodies, you enjoy and trickle through my body. I with a cynical smile slap his ass and say I still need to enjoy ... And you who are reading, enjoy with me? let it flow in me?
