Just Wanted More

I've been in this relationship for three years now, and we're both very open about sex. But last week, after a long day of work, I asked my partner to tie me up while he fucks me hard from behind. The moment his cock entered me, the sharp pain mixed with pleasure made me moan louder than ever before. He spanked my ass as he pounded into me over and over until we both climaxed violently. Does anyone else feel like this kind of rough play is necessary sometimes?
