Had a similar experience before. I'm bi as well but bottom

Got hit up by a guy and his gf on grindr. They wanted a third and a bottom. I went there and things moved fast. We started exchanging kisses then went down to suck the guy off. Suspiciously the gf didn't come down. After a while i got in doggy position and lubbed up. He started fucking me and again she didn't join. She just sat in The Chair (tm) and watched with enthusiasm. After we finished she just thanked me and gave me a peck on the cheek. She just wanted to watch her bf fuck a guy which i figured out already but was to horny to say anything. I put my clothes and went home. I tried to send a message but they already blocked me.

Would still like to try a proper threesome
