My wife wants me and her live in boyfriend to fuck… advice please

So if you follow my page you’ll know that my wife and I invited her boyfriend Dave to move in last weekend.

Last night while we were all having fun together in our bed, she made him and I kiss. It started with us both taking turns making out with her after the deed was done. She pushed both of our heads closer to each other and said “it’d be super hot if you two kissed (Dave and me)” and we did.

She goes on to say it’d be even hotter for her if him and I fooled around more and fucked.

Dave and I are both straight. Dave and I talked about her wishes this morning. We are both on the fence but we want to make sure she is pleased and happy.

What should we do? Try it or tell her we aren’t willing?

Thanks in advance.
