You see, I lust after my own step son….my wife’s son…. I’ve always been secretly bi but never acted upon it. I’ve lived a straight lifestyle all of my life. I’ve known my step son since he was 8 or 9 years old. He’s now almost 19 years old. He’s tall about 6’2 or 6’3, very slender, about 150-155 lbs but with an athletic build. He’s got a long thin face, long nose, short light brown hair dark eyebrows, long eyelashes and brown eyes that sparkle when he flashed the occasional grin. He’s a very preppy clean cut kid. Although I’m just about as tall as he is and weigh much more, he’s actually quite physically strong and could probably kick my a**. The first time I noticed him was probably a few months before his 16th birthday, he was already s******* mature by then, the same height but maybe 10 lbs lighter- I was standing behind him at a bonfire, he was wearing his high school jersey and a pair of jeans and couldn’t help notice his cute little b***. I never thought much about it but I suspect over the last year or so he became s******* active and I’ve become very intrigued. He’s a college freshman but lives at home and there were a couple of occasional nights where he went to campus or to a girl’s house and ended up spending the night. I’ve casually glanced at his crotch and don’t really observe much of a bulge- either that or he hides it well, and I’m very surprised because I simply assumed since he is tall and slender he would have a huge c***. One night I woke up to use the bathroom and saw his laundry basket near the dryer. I took out a pair of his underwear (black boxer briefs) and began to sniff them but they were clean. I’ve even gone to the bathroom after he took a dump just to sniff his poop. On occasion I’m the only one home and have been tempted to go into his room and sniff his dirty briefs or hopefully find a used condom and s*** the c** out of it…Should I? No one would be the wiser… but I may feel very guilty..then if I don’t I may regret that I didn’t
*****Update***
I was working from home today and my stepson had to get to school a day early since he works there part time as well.. A few minutes after he left I found a pair of boxer briefs in his bedroom that he just changed. I took a big whiff, especially where his c*** and balls would be as well as the crotch… It was incredibly intoxicating… A deep rich musky aroma which I can describe as sheer masculinity, youth, virility and s********, unfortunately no c** stains. I didn’t find any used condoms but found an already open box of condoms in his underwear draw as well so he is obviously s******* active which I already suspected. I feel guilty because it seems like not long ago he was just 9 years old and I’m completely disgusted with myself, but then I have to rationalize that he is now almost 19 so I’m glad I satisified my curiosity. I’m glad I wasn’t caught because although he doesn’t look it, he is really strong and would surely kick my a**
***second update****
My wife and I went out of town for a few days so my step son had the house to himself. We had to get home a day early due to unexpected bad weather. When we got home in the evening my step son’s bedroom door was closed. Then a about 10 minutes later the door opened and he had a friend from high school over. She seemed nervous, almost embarrassed when she left, my wife didn’t think anything of it because she thought they were platonic friends. My step son’s friend is also about 18 or 19 about average height, maybe 5’5″ she has long dark brown hair, a round face with a nice smile- she’s got a little extra in the a** and thighs (just a little) but a slim waist and perky medium sized t***. The next day I decided to work from home and when my wife left for work and my step son went off to school I found lavender p****** in his laundry (obviously hers) and found not one but two used condoms in his wastepaper basket. First i couldn’t get over the load left in both condoms- the ejaculate was much larger than I ever could produce. I took his dirty boxer briefs and her dirty p****** and put them on his bed and then put his briefs on top of hers. I was amazed that her p****** was at least 2 inches wider than his briefs on both ends. I backed out of sucking the c** out of the used condoms, I just couldn’t do it. But I did take some of the ejaculate and I put it on a glass slide and got my microscope out. I’ve never looked at s**** up close like that and I was enamored by the large amount of dead sperm.. I’m just so amazed how when I first met my step son he was a cute 9 year old kid and has now become a nearly 19 year old bull stud.
