Girlfriend i had once was really into being a submissive. she enjoyed being tied up, spanked, humiliated... and some more extreme torture that i was a bit uncomfortable with. She tried to get me to choke her while having sex, not exactly something i was comfortable doing.
i did try something she did end up liking alot. i simply tied her hands together being her back. i made her take me into her mouth, and eventually climaxed into her mouth. right after i did, i pushed her down on the floor, rather quickly , she was not ready for that. i had a noose already fashioned and slipped it over her neck. i then tied the other end to her ankles that i pulled all the way back to her ass. of course you cannot keep your legs like that for very long and she began choking herself on it. i just sat there mesmerized by her struggling to catch a breath when she could. a few times i pulled back on her feet making her arch herself back making the noose very tight of course. i missed the oppertunity to take a vibe to her, but my fingers did probe her enterences, both of them. she jerked and gasped as a i violated her both at same time until she eventually climaxed.
i honestly couldnt believe how much i was turned on by it, or how much she was as well.
