I dove back to him, sucking his big cock deep again. I swallowed spurt after spurt of his cum, his sweet, glorious, salty cum. My brain flashed colors...as my body erupted in orgasm. I groaned deeply, squeezing my legs together. I sucked him as his cock deflated in my mouth.“Mom,” Bobby whispered. “Do me,” he asked so innocently. I glanced his way. He was pounding his hard cock. “Quick Momma,” he whispered, pleading me to move fast. I gave Jr. a hard tug; let his cock pop from my lips. Turning. I dreaded to think what would happen if He didn't take this into consideration before punishing me. But by the third flight I had to slow down before my heart beat its way out of my chest. I tried to regain control of my breathing as I gulped air down hard. I faced the remaining two flights with steely determination and began to climb more steadily. I reached His floor just as I heard a ping sound echoing down the corridor and saw the doors closing on a now seemingly functioning elevator.. We were alone in a bed, not a freezer or a McDonalds playland. We could do whatever we wanted. As we kissed longer, I began to untie the strings on her bathrobe as she started to pull my shorts down. We both broke our heated kiss and I removed her bathrobe, leaving Megan in just her purple lacy bra and matching panties. She took my shirt off leaving me in just my boxers. I reached behind her back to unhook her bra and she didn't show any resistance. As her bra fell off, I saw the two most. .. you're my sister!" Arwen replied."Exactly. Go in thinking of the girls as your sisters, and ... wel, youcould talk about bys a bit too. That would be the clincher," Isuggested.After lunch I went to my own class, and then caught Arwen after Gym wasover, and Arwen told me "It went okay - better than I dared hope."The rest of the afternoon went even better - it was like Arwen hadpassed a test, and was now fully accepted.Finally, the day ended, and we headed home - only to see that Mom anddad.
