I am fortunate to have a close girlfriend who indulges some of my need for pain, she is very cruel by nature and is not averse to leaving me distraught, sore and often humilliated, her choice of punishment is the sally rod, it is a nasty little thing if used by the imaginative and also by one who has a deep understanding of the need to inflict sexual pain and also the needs of the one receiving it. The woods here are isolated and possess pathways rarely used, she often uses rope to tie me to posts and gates. She beats harshly. Often it causes me to moan and whimper, it is the lot of the sexually vulnerable. We both pass off as lovers and visit the local inns - if only people knew, the life of acquiring sexual need can and must be secret, it is i firmly believe part of the thrill.

I just had a mail from someone who was concerned about the pain and abuse I endured, let me state that if one goes to an isolated wood, strips off and wears girls panties and a silk underdress knowing that your co conspirator has a vicious sadistic streak there is implicit in this act a huge element of consent, knowing that certain boundaries may be crossed ampifies the sexual tension, knowing that there is a small risk of being exposed heightens the sexual tension even more, the proof is often the erection present inside my womens panties. If the erection wasn't there the punishment would not or could never take place.
