She told my wife about it the other day and I just had to share here!
My wife’s sister is 33, tall, with nice legs and a small but round butt. 30B tits.
Ten years ago, and unbeknownst to me, my sister in law saw my fully erect dick.
I was dating my wife at the time and spent the night over at their place. We were religious at the time so I slept on the couch. I, being 20, dumb, and a typical college kid, didn’t pack enough clothes for the trip, so before I went to bed I tossed some clothes in their washing machine and settled in under some blankets on the couch.
According to my sister in law, she got up to go to work the next more and came down the stairs only to be greeted by my dick standing at attention while I slept. According to her, the blankets fell off and it looked like I’d just gotten hard during the night and my dick had navigated its way out of my boxers.
