My sister Jen slid into bed next to me.
Her bed.
Both of us naked as the day we were born.
She just got back from cleaning the load of cum I shot on her stomach and chin and now she wanted to "cuddle."
She wasn't going to get any argument from me.
She laid her head on my chest and draped her leg across me as if we had been lovers for ages. She slowly ran her hands up and down my tight stomach, stopping for a brief moment before reaching for my cock.
"Jason? You've got a really nice cock. You know that?"
"Thanks." I wasn't sure what else to say. This was certainly unexpected. I mean, who expects their sister to tell them they have a nice cock, especially while stroking it at the same time?
"You've got an awesome body Jen."
"Thanks Jason." She replied. "I hope you don't mind me playing with your cock like this do you?"
"I thought you wanted to cuddle?" I joked.
In silent reply, Jen slid down and started planting tender little kisses on my chest, my belly and essentially everywhere but my now and once again throbbing cock. By taking her time and ignoring my cock, she was teasing me and no doubt also herself. She was purposely delaying, for both of us, the pleasure we would both receive from her mouth around my cock, heightening the tension until neither of us could take it any longer.
She licked and kissed her way up and down my thighs. She kissed and licked my balls. Finally, at long last, she licked the base of my erect cock to the tip and slowly placed it into her warm, wet and inviting mouth. It felt like my cock belonged there and I never wanted it to leave.
I could feel my sister's moans vibrate through my cock, sending a spasm into my balls and up my spine. I could feel the warmth of her tongue moving on the base of my shaft as she expertly sucked up and down on my seven inches of pure desire. She paused for a second and looked up into my eyes and smiled with her lips still wrapped lovingly around my cock. I stroked her hair gently and she resumed her loving attention to my cock. Just then I didn't think I could love my sister anymore than I did at that moment.
Despite having cum four times within the last eight hours, I felt the pressure of yet another orgasm building in my balls. I groaned loudly and grabbed my sister's head in my hands. I began thrusting my cock in and out of her mouth, furiously fucking her face. I could feel the back of her throat. She didn't gag and she kept sucking, anticipating the payoff. If she didn't want me to cum in her mouth, she never said so.
