I panted, watching as Mom stared at me in awe, her face coated in cum. “I’ve never had that. You came on my face! It’s so...”“Degrading?” ...aria asked. “But it comes from Sean. So it’s also sexy and hot. Makes me feel like he finds me hot!”“Yes!” Mom moaned.My sister turned her head. Her tongue licked across Mom’s cheek. She gathered up the cum off her features. She lapped it up, gathering my pearly spunk off our mother’s face. It piled on her tongue then vanished into her mouth. She gathered. I am sure several told others what was going on when the went into the other room and that was responsible for the steady stream of guys. Several left immediately after climaxing, but 6-8, not counting me, pretty much hung out and watched, most taking another turn. When she quit fighting the guy holding her hands undid pants, guided her head to his cock and basically started mouth fucking her. She was gagging and choking some but that didn’t seem to bother him. He climaxed and she choked again. Tilly started to soften and withdrew rolling onto her side on the carpet beside Francis. “You are good Francis, you can stay a girl.”“It was good for you.”“You know it kid, really super.”“My tits are okay then?”“They are fine.”“Lips, my lips really were meant fellatio then?”“Yes, they were, they fit my cock perfectly, you are a born cocksucker.”“Good, I am so unsure of myself at this point I need lots of reassurance.”“That’s just your girlish nature coming out, you’ll get better as time goes. Then she stepped up for another hug and kiss.Got to where we hugged a lot and she tried to get as close to me as she could.“Why does it get like that?” she asked me.“Things just happen,” I told her. “It feels good. You make me feel really good.”One day we were cuddling and... “Derek. Your hand...”I realized where my hand was, molded on the crotch of her jeans.I jerked my hand back. “I’m sorry. Kinda wasn’t paying attention.”I steeled myself for her to be upset. Wrong.“I really started paying.
