Shelly and Darla worked out a sign system for the door to let each other know if they had company. Which was for Shelly’s meant it could be Steve or...any number of girls that Shelly fancied. Darla quickly learned Shelly liked girls as well as boys but only ever saw her with Steve as far as boys go. Darla hadn’t found her a guy yet so the sign wasn’t getting much use from her.That changed early in the in November when Darla started dating a sophomore in one of her classes, Ben. They went out a. The sweet blonde fell back against the pillows as I began ridding both of us of our clothes. Our man was already naked watching us. Deciding to give a show, I began to run my lips from her sensitive earlobe, trailing downward, over her neck to the valley between her breasts. Pinching at one nipple, I moved my mouth to the other breast and unattended nipple. Twirling my tongue around the hard bud, my fingers began playing with her clit. Out of the corner of my eyes, I could see our third party. I sighed with resignation and grunted as if in apology, "If I wanted to fuck you Carol I would have said so not just to compliment you on your great legs and tits."She hissed in surprise at my blunt comments, men just didn't talk that way to women, especially powerful mature ladies like herself. Even though I sensed that she felt reassured by comments and even a little pleased with the rough compliments.My social skills never did get much better than that - but now it really doesn't matter does. I should have had some sort of clue when Mary met me at the door, wearing only a sheet wrapped loosely around her body. I asked her, "What?" but she stopped me with a finger on my lips and slight smile on her face. She dropped to her knees in front of me, still holding the sheet around her, and pulled my cock out of my pants. It was only the second blowjob she'd ever given me.The first was while we were still in college. She thought she'd try it as an alternative to using condoms. We were cheap.
