It was thick and hard, leaking of pre-cum. I rolled him over and grabbed his cock with both hands, stroked him in a long downward motion to slide his ...oreskin down to expose his glistening cock head. I began licking and sucking the head of his cock. He moaned gently and was thrusting his hips as if fucking my mouth. I stroked his gently as I licked and sucked his balls. I could feel his body tensing up and I knew it wouldn’t take much more to finish him off. I continued to lick him as I stroked. I laughed so hard I had to sit down on the bed so I wouldn’t fall over. It took me a full minute to recover enough to be able to breathe, let alone speak.“Now THAT was funny,” I grinned when I was finally able to speak. “But what I MEANT was advice!”“Duh!” Mindy laughed.“Subtlety and light flirting are much more effective with some guys, including me. Coming right out and telling me you want to have sex is actually a turn off.”“Oops.”“And getting into my bed unbidden, especially naked, actually. “Yes,” she cried.I was suddenly jealous. This was my boyfriend, my dream, and it felt like she was stealing him from me. Morbid curiosity prompted me to lean forward so I could see better. Mark was still holding himself back, running his glistening head inside her until she parted her knees to open herself fully.“Tell me if I hurt you,” Mark said with a serious tone.I wanted to scream stop but something kept me still while I watched my best friend and girlfriend give herself to him.Her lips. .. "You'd better stop, I'm going to cum!"I had no intention of tell him I was on the pill. I whispered back, "Just Hold off a little longer, I'm... almost... there."His hands moved to squeeze my plump little ass. I bent over low, giving him a nice view of my cleavage, and causing my silver cross to bump against his lips. Smiling, he took it in his mouth. I could see in his face he was struggling not to cum. If he knew I was on the pill then he would just cum and be done with me, so.. I let him.
