I'd say it could lead to cheating, if he isn't satisfied with what you have to offer a one finger wave should do it.
Dump the stupid pig.
Yep I would class that as cheating.
Tell him that.
See what he says.
If he's still extremely keen, dump the guy!

Gotta say--it's group sexual activity is NOT my style--but you can't condem someone's sexual preferences just because you don't like them.
For some people being watched is a HUGE turn on--or being in the same room with another couple, despite the fact that the interactions are completely seperate.
You need to sit him down and fully explain your concern about it being close to cheating--see what his reaciton is--and go from there. Complete honesty and open conversation is key.
Obviously you're not into it--if he can't respect that, -THEN- dump him.
However if he understands your concern and is more than willing to retract those requests and forget about them--then all's well.
Gotta remember, there are all types in this world, the ability to empathize and live with different types of people is beautiful.
If you go... it will end with your bf pumping the other woman and the other man pumping you. Straight out.
A boyfriend asking that shes zero respect and sees you as a sex machine. very selfish.
