Yes I have to agree with your comment 100% I have a retired friend very well endowed and fit who likes to give me anal he likes to work on me brutal with full length thrusting and grinding in hard and yes I do get well stretched out with a long session in the end I always reach a powerful squirting orgasm when he fills me up leaving me shattered.
this is the ideal position for a man with a big penis to get into a woman's posterior fornix and really give her a full and stretched feeling. A lot of woman have vaginal orgasms if a man can keep up that performance for just a few minutes
