One night, I lay in bed with my girlfriend. We had just finished making love and she'd had a satisfying orgasm. She was on her stomach, with her knees bent and widely parted - her favorite position after an orgasm. I asked if she'd like to try something 'different'.
"What did you have in mind," she asked.
"Would you like to find out if you're anally erotic?"
"Are you serious?"
"Sure," I replied.
"Um..... how is it done?" she asked.
"It's very simple," I said. "I'll be right back." I went to my bathroom and brought back a tube of lubricating gel. She watched as I squeezed out a generous dollop of gel onto my right fingertips. "Now, I'll gently apply some to you," I said.
"Um..... where?" she asked nervously.
"Between your buttocks."
She seemed surprised.
"Um..... okay." (She often says 'um' when she's nervous.)
"Just relax..." I said in a soft, reassuring voice, as I applied the gel to her anal area.
I slid my left hand beneath her 'tummy' and lower... until the tips of my middle and ring fingers found her already erect clitoris. I began to stroke her, at the same time that I gently pressed some of the gel into her anus.
"That feels... um... different," she whispered.
"Do you like it?"
"Um.... do it some more..."
I did... and she began to moan softly. It wasn't unusual for me to bring her to orgasm in this way and position. I could see that she really enjoyed both kinds of stimulation. In less than 3 minutes, she was seconds away from what promised to be a huge orgasm (I can read her very well by her sighs, moans and movements). In that ONE second, right before her orgasm starts, when her vagina and anus relax - just before her orgasmic contractions begin - I easiy slipped most of the length my middle finger into her anus. THAT did it. She moaned loudly - in ecstasy - as a tremendous orgasm raced through her body and took her completely apart.
"UUUNNNHHH!..... UUNNHH!..... UUNNHH!..... UMNH!..... UNH..... unh..... unh..... uh..... she moaned, as her anus contracted tightly around my finger, in exact sync with her vaginal contractions.
Munutes later, when she was back down from 'cloud nine', she looked at me and a small grin played at the corners of her mouth.
I smiled at her - a warm, affectionate smile.
"What did you DO to me?" she whispered.
"Did you like it?" I asked.
"Yes," she whispered, "VERY much..."
"That," I explained, "was an anal orgasm."
Her eyes went wide and her mouth formed a perfect "O".
"Do you remember me mentioning medical fetish... and gyno fetish? I asked.
"Um..... yes....."
"Well, that's just a sample of what it feels like," I told her.
"I... I'd... I just wish that I'd let you do it sooner," she said softly.
Long story made short: my girlfriend is now in the process of learning a whole new source of pleasure... and I'M her teacher...
