My girlfriend, who I live with, went back to her parents' house for three days. - My girlfriend's friend Elisa came to check on me so I wouldn't cheat on her... Even though I knew it was wrong to cheat, I was glued to Elisa's voluptuous G-cup breasts... "If I could hold back for two days today and tomorrow... - , You can have sex with me on the last day♡'' I can only say ``yes'' to this unexpected proposal, and as I do, I end up in a tit-fuck hell... - Aiming for sex on the last day, I hold back my ejaculation. - On the last day, there was an explosion. - Sperm that won't wither no matter how much you let it out, an erection that won't subside. - It doesn't matter if I'm cheating or not...I'm obsessed with the G cup breasts in front of me. - To her...I'm sorry...
