Since it was near Jennifer's leg, she could feel it too."You know, I should show what I've learned so far," she teased, before putting her hands on my...chest and shoving me backwards. I got myself to lay flat on the couch just as Jennifer laid on top of me, kissing my neck and slowly going down to my upper chest.I let myself relax as Jennifer showed her supposedly new skills. Her tongue and lips covered my left nipple, and I just put my hand on the back of her head. I went back and forth between. As the tub filled, I cupped her small, high breasts and gently kneaded her already-erect nipples. They stiffened to my touch, as she began to sigh. My shirt soon joined my pants on the floor, and we sank into the tub of warm water.I turned her around with her back to me, and began massaging her tits with soap. Gradually I worked my hands down her belly, teasing at the triangle of her pubic mound. She could feel my erection pressing into her back, and slid invitingly up and down it, only. I had managed to get a good job as a junior engineer right out of college. I had gotten a promotion when I had been with the company for one year and had gotten another one just before Amanda left me.I had no idea anything was going on, but I found out later that Amanda had been sleeping with the guy she'd left me for for almost a year. The guy had sold us a life insurance policy on me right after I had gotten my first promotion."Mike, you could spend weeks just mapping those mammoth mammaries.. But she had not wanted to make this easy for herself, hence the tied tits and legs. though she could, perhaps, roll over onto her back, with considerable effort, but if she did that, she would not be able to roll back on her stomach, and she needed to be on her stomach for when the post arrived the next day. She could crawl on her stomach, just about, but not on her back. Besides which, she would be laying on her cuffed hands, and could perhaps inadvertently tighten them, cut off her blood.
