Mark climbed up on the couch and squeezed himself in between her and the back of the couch. Anne opened her eyes as Mark grabbed the sides of her head...and pulled her mouth down on his cock. Her mouth resisted for an instant before he shoved the cock head, and the rest of the shaft, inside. He forced in as much as he felt she could take and started pulling her head up and down on his penis, jerking himself off with her mouth.Anne closed her eyes as the sensations between her legs betrayed her. With much hard work she had prepared herself to attractthe attention of a beautiful woman, a high ranking Commander no less, andwas now the Sissy of a large house. She had simple duties like runningerrands but spent most of her time primping and exercising to keep herselflooking gorgeous. Her Commander, Gabriella, liked to show off herbeautiful Sissy at the many social functions that such a high rankingofficial was expected to attend. A Sissy's most important duty was themonthly Insemination. Instead of hiding herself Lilly asked if Penny also masturbated or not? After the death of their real mom both sisters had come very close to each other and shared everything, so with a little shyness Penny nodded in yes. Lilly came to Penny's bed naked, and she asked Penny to take off her panties. Both sisters had seen each other naked daily, so it wasn’t a big deal. Lilly made Penny spread her legs and she touched her pussy, now Penny felt a little weird, but excited. “Feels good, isn’t it?”. "Milly, what are you doing?" I asked.She turned to me and placed one finger on my lips and said, "Sssshhhhhhh, enjoy."She sexily lowered her tight skirt which revealed a skimpy black laced thong, then her top came off revealing her beautiful double D breasts in a bra that matched her lace thong. Her skin was glistening from the light of the TV. By now my hands were off my twitching cock and I so wanted her to carry on.'She never calls me Dad, so does that make it ok?' I asked myself.Either.
