he got betrayed by his female friend...
doesnt that imply a intentional decision out of free will...
also with the slave ring being visible like that he couldnt have realy missed it...
Hahahah the mental image, of her just doing a miming performance of a blowjob, without her actually even touching MC (or his member), and him cumming just from that, made me actually laugh. That's how it looks if you interpret the images "literally".
just a little tip... the spanish (latam) version uploaded by Marrano-kun scans in this site has this chapter de-censored. You can use it to complement this reading.
