It was with a sigh of relief that we stripped out of our clothes. I had gone an entire day without seeing what was under your shorts and t-shirt and ... wanted to feel you up against me. We fell onto the bed, our mouths hungry for the passionate embrace as we began a long French kiss as we ground together. In only moments I rolled over, from beside you to on top of you, and even though it hadn’t been my intent, with only a slight shift of your hips you ensured that my massive hard on was. The sound was a higher pitch than the last. I knew I had broken skin. Her legs clamped together and her hips shot off the mattress. I brought the belt down across her back and across the back of her legs. She pressed her mouth harder against my rock hard cock. Using it to muffle the cry she let out. The heat of her breath and increased pressure on my cock sent shivers through me. I pulled her mouth off my cock and let go of her hair. Her head dangled and swayed off the mattress. She looked up. I agreed in a shot. I love bikes and its be a while since I was on one.She was only dressed in a bikini and I asked if she intended to ride like that. She replied "No never. I always ride nude" As she said this her right tit popped out for me to see. We both laughed but she made no effort to pop it back into her bikini. It was a very nice tit with a big nipple. A few seconds later she pulled on her bike gear. Helmet and gloves. I nipped up to the house and got my own gear on. I have to admit. She opened her eyes again and saw that David was staring at her.“Mum I’m going to…”“I thought so! Don’t worry. Just let it go!” David screwed his face up and then suddenly gave a grunt. Helen closed her eyes as once again she felt her son’s semen thudding into her pussy. This time there was no need for her to bring herself off. As if sensing she hadn’t yet come she suddenly felt a hand at her groin and opening her eyes she saw Rose’s fingers delving into her groin, searching for her.
