Slightly adult so I'd better post here.
When I was 16 I had an older (mid 20's) guy friend. We never dated but it was him who got me into this. The first bunch of times he tied me up all pretty much followed the same pattern,I guess it was to get me used to it.
To start I'd kneel on his bed facing the headboard,normally I'd be wearing jeans & a top. He would (from behind) ballgag me. Then he'd use rope to securely bind my wrists behind my back. That done he used a long length of rope to tie a chest harness,squeezing my breasts by passing the rope both above & below them. At this point he'd come to kneel infront of me & would ask if I was ok. I would nod & give a slight mmmphh through the gag & he would kiss my ballgagged mouth & briefly fondle my bound breasts,always produced a lovely tingle inside. After helping me to lay on my belly he would hogtie me,rope around ankles & rope to link ankles/wrists. This link rope was sometimes very tight sometimes not so much.
At his request/command I would roll onto my side. Leaning in he would strip me whilst I remained tightly helpless. Always my jeans were undone & my top pulled up/down. Sometimes my jeans were also pulled down to my ankles,sometimes my thong joined my jeans down there. Sometimes my breasts were 'popped out' of my bra. So at it's most extreme I would wind up laying tightly hogtied & ballgagged with both my breasts & pussy fully exposed.
