“This is an exercise to see how...” I paused, took a deep breath, and pulled down my halter. Everyone gasped.... “much a girl’s breasts can ma...e a penis stretch. So let’s see the penis.” I tugged down Zach’s shorts. His blue cotton underwear snagged on his erection, but I twanged the waistband and down it came. “Now, guys, I don’t mind satisfying your curiosity about my boobs, and I won’t leave you hanging, but it’s all boobs and oral. I keep my shorts on and you gotta promise never to talk. To make the ride better, I started to thrust my hips up into her pussy whenever she would thrust herself back. After a couple minutes she said that she was getting tired of riding. It was her first time, so I didnt want her to get too sore. I decided to lift her up by her sexy ass and just pump my cock into her while I carried her. Michelle wrapped her arms around my neck as I thrusted into her. Michelle got back her rhythm as it was easier for her not to do all the thrusts. Michelle seemed to. .YOU GOTTA STOP!!!"I shook my head best I could and gargled a negative and continued sucking his juicy shaft. His whole body was starting to shake and tremble, then the point of no return.The first powerful, salty spurts of his cum hit the back of my throat with force, then came the hefty spurts; I could tell it was very thick, clearly Frank hadn't ejaculated in days, the taste was exactly what I like, no bitterness, clumpy and rich, I squeezed out the last thick glob and savored the taste for. And that also probably means that too little food could be a serious threat to his life. Already, as it stands, it has been two nights since his conception – three if I count tonight – and I haven’t eaten a single thing. I would like to get some food down before either the pain stops and the pleasure shackles me again; or the serum wears off and the pain cripples me. “You’re wasting time!” I fight against my bonds desperately, hoping he will see that I am earnest.He deliberates one agonising.
