A tentative lick between kisses and I find the taste of your warm flesh to be as delicious as always. My tongue involves itself more eagerly now and f...or a moment, I forget that those lips that I kiss are not the ones where your own tongue can reach out to meet mine. A single bead of moisture rolls down the crease of your nether lips and as I catch it in my mouth, I realize that it is not the product of my own lascivious salivating, but the first signs of your liquid arousal. Spurred on by that. The fifteen year age gap certainly wasn't a problem because we were glad to have their experience to learn from.We went out to dinner and got acquainted and no one mentioned anything about swinging or sex. They noticed our tact and this was something they were looking for, because it showed we knew the importance of discretion. When we got back to the house they came in and we talked some more. We had agreed there would be no sex that night.But when the subject of the photos we'd swapped came. Her big pink, erect, nipples were very nice. I started sucking on her tits and she began moaning. She was going crazy. She started kissing my neck. I unbuckled my belt and she climbed off and pulled out my nine inch dick. She started sucking. She wasn't the best at it, but she wasn't bad for a virgin. She took a little longer than normal but after about 15 minutes of non-stop sucking, I shot my hot creamy load down her throat. She was kind of shocked but that didn't stop her from swallowing. I pulled her close to me and made her sit on the edge of the bed and removed her t-shirt. She was in her slip and did not wear a bra since she did not have very big boobs. She was shy and reluctant the moment I removed her t-shirt.So in order to make her feel comfortable, I switched off the lights and removed my shirt and shorts. The dim light from the windows was more than enough to see her eyes anxiously expecting what was going to happen. I slowly removed her slip and made her lie on her.
