The Asian Commercial Sex Scene - Looking for Couple Swap / Same Room Sex

I and my bf are looking for couple swap and have same room sex. We are genuinely in love and very horny most of the time. We would like explore more in sex. We have done some outdoor sex. He always said I have very tight pussy and my BJ skill is superb. I started to lick his asshole recently and he likes it a lot. He likes to lick me. Sometimes use hot & cold water to lick my pussy. When he finger me, i can be very very wet. He likes to drink my juice. We always fuck in my office, outdoor and hotel. He wants to see get fucked by another guy and suck him at the same time. I want to see him fuck 2 girls at the same time too. So far I'm straight and I can try to pleasure another girl. I like boobs too.
