i found this on another forum...
things are going good for me lately. me and my fiance are in love and and will be getting married very soon. her parents love me, everything is going great....but something has been bothering me the past couple of months. her younger sister, who it totally hot, has been coming on to me. yes, i think she has a thing for me.

and you know how tempting it is. but i have restrained my self so far.
last week she wrote me a letter telling me of her undying love for me..

...and says she wants me to make love to her just ONE time before me and her sis tie the not and no one will ever know. i told her it would be wrong and i couldnt.
well one day last week i was at their house and my fiance and her parents had left to go the store....we were alone. of course she came on to me....as i was standing there she walked halfway up the stairs, took off her underwear and threw them towards me down the stairs, she started walking towards her bedroom motioning for me to follow.....
i stood there and thought for a minute...i started to follow her... but then i turned around, went out the door, pulled out my keys ,and headed toward my car. then suddenly her father approached me smiling with tears in his eyes. he said "congratulations. youve passed our little test. now i know you love my daughter and will be faithful to her."
and the moral of this story is:ALWAYS KEEP YOUR CONDOMS IN THE CAR!
