This may not be for every one and I havnt seen it on any porn sights so Illtry to explain.I had a great sexual relationship with my ex and we used to try differet things .She had a new vibrator with rabbit ears ,I started to play around and had it inside her with the ears tickling her clit .We had tryed anal a few times and it was a sometimes thing any way I had the but of the vibratr ballenced my pubic bone and my cock just slightly in her ass. As she was getting extreamly excited by the vibs and started to realy work the vibrator as well as my cock she was pulsating in a way that baught us boath to extream orgasms and resulted in the most powerfull sex we had over a 3 year friendship. We tried it about six more times and every time with the most enormus convulsing orgasms for boath of us . Its worth try if your a little adventures . You dont have to be fully inserted to get the benefit of the muscular contractions . Good Luck and enjoy
