TW: dub-con --- Make the straight guy who played with your heart understand using your big dick! "Yuri... Please have sex with me." "Are you serious? But I thought you were straight." Keisuke (the bottom) is ordered by his girlfriend (see note below) to go get trained by his gay friend! Yuri (the top) had confessed his feelings for Keisuke many times in the past but he was always rejected. Now he takes this opportunity to explore his ass with his big dick! And train it! "Watch carefully! Because right now I'm about to make your body become unable to cum without my permission!" "Because" there is love, the sex is both very cruel and lovey-dovey! "I'll make sure your body will never be able to please a woman ever again, Keisuke." * About the bottom's girlfriend: She does not appear in this. Keisuke and his girlfriend were only together because it was convenient for both of them and there was no love between them. In the end, they break up, but the reason is just that "she got tired of him." She doesn't seem to mind the breakup at all, and at that time Keisuke's ass was making him feel so good that none of them grieved the breakup howsoever.
