FSDSS-649 _When your lover's younger sister is even more delicious and slutty than you

I didn't know my girlfriend had a sister. And what surprised me more was that she was even more beautiful than my girlfriend. Perhaps, I have been obsessed with my lover's sister since that day. Yes guys, I think I've fallen (extremely) in love with my lover's sister. This is wrong, but her body is even more wrong. Why does a girl who just turned 18 have a slim and toned body like a model? The bad thing was that it seemed like she also realized my feelings and started to crawl into my lap and suck my cock like she was sucking on a lollipop. We kept making love day after day.
