..," she breathed heavily. "I can see you've been studying too hard for this one. Wanna release in my mouth right now?" I leaned close to her face, s...ying, "I don't want to spoil it too soon, baby. I wanna enjoy your new challenges by watching and jerking off." Her face gleamed up. "Really? What challenges?" "You remember we talked about the things we have on our bucket lists?" I asked, and spanked her face with the head of my cock lightly. "Yeahh...," she moaned. I dared to bet her panties. How had it come to this?Her idle curiosity was just a passing fancy, the answer did not matter. She was happy, and comfortable, as if permanently held between worlds, the pleasant lassitude as one is about to claimed by sleep, or in those few, alert, seconds after waking, when the day seems bright and new, before one's problems flow into consciousness like a breaking wave.She had no problems now.As she drifted on light pleasure, she had no will to move a muscle, looking forward to the next time. As far as body, who’s to say? But I can make some guesses about that.”“Oh you can?”“Sure.” Now it was time to put that lecture on teen titties to good use.“Have you seen Linda ever without her shirt and bra on? Shower at school, or changing clothes or something?”A slightly reluctant nod.“OK, and you’ve seen her mom and sister. Her mom is a D, and her sister is on the upper B lower C range I would say. Now mind you, what I know about female breast development is purely theoretical.” That got me. She showed me those pictures and let me say, he was very well hung. Thank god for digital cameras! Last night she made up her mind, and handed me the phone to give him directions to get to our place. Kim and I are in our early 40's and usually Kim picked men around our age to party with. After seeing Jim's beautiful cock pictures I could understand why she made the exception in his case.Kim was completely honest with him about us and what we were into sexually. When I talked to him on the phone.
