” He growled.“It was for your own good, you were getting randy.” She said sweetly.“I’m allowed to get bloody randy with my fiancée.”“Oh...on a lap top, where’s the fun in that?” She asked.“Well I may have forgotten what you look like.” Even he thought, that sounded feeble.“You’ve forgotten what I look like after only a few days?” Pretending to sound annoyed.“Four bloody weeks Terry.” He knew she was winding him up.’They began to talk about general things, he told her about what Tim had said. She checked the coast was clear and dragged me over to a hut that was empty and currently under construction. “Quickly before anyone see” She pulled down my pants at which she could see the full extend of my erection in my boxers.“Wow…..that’s a big one” she gasped.“Mom!”“Sorry dear, now hurry, ill turn away”I started to jerk, but it was difficult to cum. I had no material to masturbate too.“I can’t finish, im struggling” I said.Suddenly I felt my Moms hand grip the base of my cock. I gasped. My balls began to tighten. I felt both of them lift and come closer to my body, getting ready for that magic moment. I began to moan even more loudly. My sister began to sigh as she continued to suck. This time, she ran her tongue in circles around the cranium that was filled with blood. That was bringing me closer to the edge. And she knew it.“Oh, my. Is somebody getting ready to cum? Am I going to make you cum, honey?”Honey, I remember my sister saying like I was a boyfriend she had. I guess even she was not used to lock her door to get dressed, after all she just reached her puberty, how would she know. But slowly my thoughts went on to her boobs. At that time I didn‟t get it.

My mom took me aside and said I shouldn‟t ask such type of questions regarding girls. But she told me that my cousin has.
