I met her some years ago. I was living outside my country and internet was a cheap way to keep contact with home and my gf. We start chatting about trivia and literature. History, politics, many subjects along the months. No chat about relationships, nor sex, since she was still married at the time and I was with a gf. But life changed for us in months. She divorced, and I broke up with my gf. We still had some IRC chats (we were living in different cities) and once we discovered each other in sexually explicit chans. So our chats were about sex & fantasies.
We start scening some situations, it was like writing a four-hands-roman. Imagining situations. She admit she had some dildoes, so we introduce them in our fantasies. I don't remember exactly how it happened. I think it was joking, I told her about pics I've seen of women fucking women with strapons. She know that toy existed, but never had one. She found the idea interesting, and we develop a fantasy with a strapon. And we both agree it was funny.
Months later I got some days off to visit my family, friends and to know her in person. She got her car and drove home, pick up a small travel bag and whispered "I've a small surprise for you". During dinner she told me she was going to start a relationship with a man and she had bought some presents for him, they were in the bag and included a strapon -which she gave me a quick flash. But she wanted that we use the gift first together.
We had a dinner, some dance and we went to a motel. Petting, kissing, licking... she asked me if I was sure about trying it. When I agree, she went to the bathroom and come back wearing the strap. We play with it, teasing and kissing, as a natural play. Then she got me on elbows and knees on the bed, and start teasing me with her fingers and some lube. Once I was dilated, she fucked me slow, nice and deep.
We were both rookies with the toy, so I didn't cum then. She was so nice to make me a blowjob just to finish a great night.
