I felt at ease with these two older gents. They were touching me up and it was lovely. I was starting to get excited. My wife nipped in to see them fo...dling and petting with me.My wife told them that I loved sucking cock just as much as she did. I was shocked because I had never sucked a cock before. But somehow I knew it was about to happen. Both guys stood up and started to strip. Down their trousers came and out popped two very erect cocks. Both were bigger than mine. One guy pulled his. He lifted her back onto the desk, kicking his shoes off along with his trousers. As he kissed her, he caressed her firm breasts and nipples with his hands, making her moan gently into his mouth. He trailed soft kisses down her soft, supple body, stopping at her breasts to suckle and bite her perfect nipples which elicited small gasps and moans from her. Hooking his thumbs in her panties, he kissed her belly button, then slid them off, exposing a perfectly bald cleft that glistened with her. " Are you on birth control, geez, I almost forgot?" Oh, yeah, for three years now, good thing, too," she snickered.I had really forgotten to ask her, I was so used to having sex with Amy, she's on the pill, that I only remembered when I was feeling close to cumming. I could not imagine the problems involved with getting my little sister pregnant but, thankfully, that wasn't a concern.She lifted her legs up onto my shoulders as she wiggled her butt back and forth as I fucked her tight little. I pulled her hair a bit and guided her up and down on my dick, she didnt need much urging, she knew what she was doing. She kept moaning - "dont stop, oh my god your tounge feels so good on my tight slit." She never lost suction of my cock as she was saying to Carson to keep going. She shuttered and shook as she came hard on his face. He got up and told us all to go to the bed. He put her on all fours and started railing her. I put my dick in front of her and she knew exactly what to do. .
