Lubricating my penis with his semen

[Marlin]

I'm lucky to have a Fuck bud who has no inhibitions. He's 26, Asian with a fat uncut 7" dick. He's very smooth but has a nice thick bush and a hairy hole which I love. We are both poz, undetectable and so obviously we never use condoms. Our sex is passionate with lots of kissing, mutual oral and rimming. I especially love eating his hairy hole especially when he comes over already filled. 
The other night he came over, undressed, and started sucking me getting me super hard. After a few minutes, he sat up, startled me, sat on my face and I began eating him out. He didn't tell me he had already taken a load but I immediately smelled it and tasted it. All of a sudden is hole opens up, his rosebud swelled and the fluid came running out into my mouth. The taste and scent of marinating cum filled my senses. When his hole was empty I reached up to kiss him, wanting him to taste what I was tasing. Our mouths were now sharing our saliva, semen and ass juices. We kissed for a long time transferring  the fluids back and forth. 
I rolled him over on his back while kissing him, broke off the kiss and punched his legs over his head. I reached down to his wet hole, ate whatever I missed then lined my dick with his and slid in so easily. I fucked him while we kissed but didn't last and quickly shot my load
