I bit her nipples and then gave a lip lock which lasted for another minute. Then I pushed her on the bed. I joined her and made her lie on me. I could...feel my cock touching her pussy and it was like a dream for me. But I realized that both of us were top of our lust.Suddenly, we heard the doorbell sound. She thought our parents had come. But I knew my parents won’t come now and so I didn’t stop ‘my work’ on my sister.I started inserting my cock inside her pussy and started thrusting in and out.. " Well from what little I understood of it, it sounds most entertaining."An awkward silence grew, Mary couldn't think of anything to say to continue the conversation and felt increasingly nervous under Mr Anderson's gaze."Well then, I'll pop up to check on them I think. Janine will settle your payment; I believe she is in the bedroom." Ok. Goodbye Mr Anderson, nice to see you again." And you too young lady."As she watched him disappear around a corner she breathed a sigh of relief."Nice to see. I'm feeling pretty good, just relaxing and drinking on my favorite liquor, Hennessy and coke. I hear Liyah's bedroom door open, I glance down the hall to see her walking to the bathroom in nothing but t-shirt and panties. Damn I thought to myself, my eyes fixated on her slow twitching ass bouncing as she made her way. She opened the bathroom door, stepped in, turned around and locked eyes with me as she slowly shut the door. Now I'm puzzled, heart fluttering and excited at the same time. Damn,. Stroke his balls while you're tonguing the head of his dick. Playing with the balls while giving head is also a good way of figuring out what he likes if your boy's not very vocal. Typically the balls will sort of scrunch up a bit when something feels particularly good and they'll scrunch up completely when he's about to cum.If you do the above techniques, he's going to last longer usually, so if you're getting tired or "cocksucker's cramp" you might want to speed things up by doing the age old.
