I could feel his mounting excitement through his jeans, and ground my body against him. He groaned as I teased him through his clothes, sucking on the... tender spot on his neck. His hands where busy unclasping my bra, a skill he had long ago perfected. But now he fumbled a little as his hands shook with desire and anticipation. I blew softly over his ear and whispered gently, “I want you.” I continued to grind into his lap. “I want you,” I whispered again. Now he was kissing my neck, and pulling. His cock was rock hard and touching the wall as Tom pressed against it, daring not to make a sound.His eyes grew wider and he thought he was about to have a heart attack as he watched his beautiful young Sister reach behind her back and unclip her bra. As she slipped it from her shoulders and dropped it in the laundry basket Tom let out a sigh, which sounded so loud in the quietness of his room. He stared at Emma's gorgeous naked breasts, they looked so big and round to him, and he loved how. She knew I hadn't had anything to drink. I decided to try some humor."Would you like me to whip up a Bloody Mary for that?" Ugh," she moaned. "That's what it feels like, which is why I don't usually drink."I almost thought up a good rejoinder, but her next words stopped my brain cold."I don't think I caught as many details as my mother got from you, but I've got to go write down everything I can remember while it's still fresh. If you don't mind, I'll need a minute to find my laptop, and then I. You shudder. You pause, taking it all in. You head tilts up. Your eyes are closed. I slowly come to. The sensation in my groin is beyond imagination. An unbelievable feeling. My cock is so warm, in a soft gentle vice. As if I died in my sleep. You lower your head and smile. I see you in the darkness, eyes have blurry I see dark shapes. No details, I feel you. Knowing its you. Letting myself go. You lean down to me, closer. Feeling your warm tits on my chest. Your pussy tightening on my hard.
