Staring right into my eyes, she tries a few tentative strokes up and down the length of my shaft before rising up on her knees and moving her mouth towards the domed head. She questions me with her eyes just before her lips reach me. I silently nodded as she plants a kiss on the tip of my dick.
Based on what I heard and saw earlier, Lauren is no stranger to blowjobs. Instead of diving right in, she teases me by licking up and down the sides of my shaft, coating the length with saliva. It is so fucking erotic the way she maintains eye contact with me the entire time.
With one hand gently cupping my balls she licks all over my cock, concentrating her attention on the sensitive underside of it just below the head. Even with three other naked girls to look at, I couldn't break eye contact with my sister if I tried... and I didn't try. With our eyes locked on each other it's like no one else in the room exists.
Finally, pulling my cock down towards her she slides her lips over the head while her hand strokes up and down my shaft. I emit a low moan from deep in my throat as she corkscrews her hand up and down my shaft and slides her lips farther down my hard dick.
Damn! My sister knows her way around a penis. This is already one of the best blowjobs I've ever had and she's barely gotten started. I'm not sure how much is due to her skill and how much is due to the fact that she's my sister. Either way, I'm not complaining.
Lauren continues stroking my cock while she takes a deep breath. I know what's coming next and apparently so do her friends.
"Here she goes," Kylie says, breaking the spell between Lauren and I. Fuck! I wish they would just watch quietly. Doesn't matter though once Lauren's mouth engulfs my cock and she slides her lips about two thirds of the way down, I don't care anymore!
"She's doing it," Kristina marvels as she leans in for a closer look. I reach up and pinch Kristina's nipple just as I feel my cock enter my sister's throat. Fuck!
Lauren pulls back along my throbbing shaft and continues stroking my cock as she gasps for breath.
"You didn't hit his pubic hair," Kylie announces.
"What?" Lauren, yells at her. "He was in my fucking throat!" I can vouch for that.
"True deep throating means you take his entire cock," Kylie says, sassily. "Your lips have to hit his pubic hair." I'm not sure where she's getting her rules but it's an interesting one.
"And you can do that?" Lauren asks?
"Yup, sure can," she answers.
