I personally, dont like to touch myself while having sex.
With my housband, he perfectioned, i can say, the way he take me, now he makes slow constant penetrations, sometimes change a little bit the penetration touching other parts of my interior, I also like to be taken lyling face down, so he reaches the right spot inside me, this with his slow motion and constant penetration, he will make me cum, sometimes twice if he last longer.
Mounted by a dog, usually I am more wet from the beggining, during the violence of penetration i am being already prepared, once knoted the manipulation inside me is very intense, the warmth, his knot pulsating, his eyaculation specially at the beggining, the feeling of being steched by his member, specially with Chamo, usually this manupualtion last longer than with human, making the mating more intense, I know it this because I am breathing in mouthfuls, finally I will cum, usually very intense way, I may have a second orgasm while I'm still knotted, o while I am being celaned sepecially with Chamo who was addicted to lick my sex.
So I dont need to touch myself at the end
