Jerking in Secret

I was in the front room watching TV and my sister and three of her friends were over for a sleep over. Later on they all went off to change for bed only to return a while later wanting to watch some late night TV.

To begin with they sat in a circle to play a card game, UNO and glancing over I had a perfect panty shot of one of them and was strangely aroused at the sight of a teenaged girl's crotch. As I stole a look she had the heel of her foot jammed right against her crotch and was rocking on it. Her face was flushed and she must have been really feeling it. I began to get hard. In a while, one of their favorite movies came on, so they spun around and lay on some cushions, heads in hands to watch the movie.

I was now safe to check them out and I checked out their tight firm young bums beneath their PJ's with tight panty lines showing. Lena, whose panties I glimpsed earlier, had on a night shirt and it rode up over her bum exposing her white panties. As she wiggled about, I became very aroused watching.

I turned off the light to add a bit more effect to the scary film, thankfully there was still enough light for me to check out these cuties lying in front of me. I let my hands rest in my lap to squeeze my dick as I stared at Lena's smooth thighs and tight bum and those cute panties. As I continued to watch she had lifted her top half up onto her elbows and she was sort of rocking her lower half. As I watched her, I realised she had positioned herself over one of the cushions and was pressing her little crotch down onto the edge of it. Wow, she was a horny little thing, I thought as my cock began to throb.

Then the girl next to Lena asked what she was doing and she casually replied "nothing, I am only riding my horsey" For the next half hour I brought myself to the edge a few times as I watched Lena humping the cushion. Her panties were now wedged up her bum and the hard corner of the cushion rubbing tight between her slightly parted thighs. After a few more hard slow grinds she suddenly let out a kind of moan combined with a yawn, her whole body went kind of stiff, then her bum got very tight, and her hips began to jerk back and forth.

I couldn't take it, and I spurted quietly in my boxers as I dreamed of her sweet pussy twitching and juicing around my cock. I really wanted to shoot my cum right into her crotch.


Now, every time I masturbate I picture her squirming little butt in her thin panties.
