have you tried that? you basically spit on your dick and hands, place your hands U-shaped together to make a tight wet open hole. i place my hands on my bathroom sink and then just fuck them and spit when needed. it was hard to cum this way after years of just wanking off but it was worth it. its more similiar to sex - you get really exhausted an sweaty, cum much harder, the whole thing is slower and takes longer. the only downside is that the sink is cold so its kinda bad at the start but after you imagine youre fucking a cute femboy it gets better.
