Was back when I was in college and dating a tall, young lady. Long dirty blonde hair, a shade darker than pale, glasses, slim, nerdy, bit of a flower child... One night, we were laying together and watching a movie. She was in front of me, and we were both laying on our sides. I was rubbing her back, then felt the compulsion to move her hair and start kissing the back of her neck. She jumped a little at first, but grabbed the hand I had on her shoulder and squeezed it a bit. Then I started moving down to her chest. She squeezed my hand around her breast, so reciprocated and started to fondle her. We were both shy... but was quick to find out we both wanted each other. I reached my right hand around and pulled her tighter to me. She undid her pants and I followed to start playing with her. She was already grinding against me to make the stimulation a bit more intense. We'd talked before this. She wanted our first time to show she was giving herself to me. Not like S&M, but to be mine to do as I wanted to her and explore her as it was my first time... She said to wait so I stopped and she left to go into the bathroom. As you can guess, I tend to worry, and was afraid I'd done something wrong. That feeling went away immediately when she came back wearing a thin collar... she walked back up and led my hand back up to her breast to show she'd also taken off the bra and put the shirt back on. We didn't have leashes or rope, but I had suit ties. The first one tied her wrists together. We were both kind of nervously laughing when that was done. The bed frames were really off the ground, so I got the little desk chair, sat her down, lifted her arms up a few inches above and behind her head, and started kissing her while tying her bound wrists to the frame with 2 more ties. Then she asked if I could cover her eyes. Said she liked not knowing what was coming. So I abliged, took off her glasses and used the last tie to cover her eyes. She was wearing a button down. She had a nervous but excited giggle as I undid it from top to bottom, being careful not to let the shirt completely close but not letting her be exposed yet either. Her legs were spread with the button she'd never fastened back, so I knelt slightly with my knee at the edge of the chair. I grabbed each half of the shirt just below the shirt collar and pulled them apart, blowing air down from her neck to her stomach. This made her gasp and she arched back slightly. This was the 1st time I'd seen a woman's breasts in person... She was either high A or low B cup, very soft.. Her breaths had a shallow quickness. She had goosebumps. Her nipples were light and erect. I put my hands on her exposed waist and slid them up while my knee moved forward to put pressure on her groin and I approached to meet her lips. Our tongues were already exploring each mouths when my hands reached her breasts. I encircled their bases with the outside of my palm so that my index finger and thumb were able to gently pull and twirl her nipples. This made her moan and arch again, but kept moving her thrusting her hips to grind on my knee. Not sure how long we did this. Wanted her to have fun so held out until I couldn't resist anymore. I moved my hands back down to waist and kept going... her pants pulled down and off as I moved them down her legs. I kissed down her body to just below her belly button, then pulled back and started kissing the inside of her leg from her knee to her pussy. She was already so wet.. I gently spread the lips and kissed up toward her clit. When I reached it, I sealed my lips around it, and sucked slight as I put her thighs over my shoulders and lifted her out of the chair. I think she was hanging onto the bed frame, but my hands were pulling her ankles to have her feet rested against my back. If she was scared, it didn't last long.. i could feel every squirm and pull as I flicked and circled her clit with my tongue. Heavy breathing became gasps, which then became moans. She'd uncontrollably squeeze her thighs against my head in the same spasms that her back would arch. Might have mistaken it as attempts to pull away if not for the repeated "please" and "don't stop." She finally had one large spasm and wad breathlessly repeating "okay, okay,.." so I knelt back down and let her slide forward to gently set her back in the chair. Her legs, chest, and stomach were trembling. I leaned in close to ask if she was okay, but she was already moving forward to try to kiss me again. So I met her lips again. "I hope you're not done," was the first thing she said, and I wasn't. She was very wet, and I didn't even think to let her suck or spit on my cock. Didn't need to. Nor did I know why she started to breathless giggle as I slid my member back and forth on her clit to tease her. I've since come to learn that I'm a little more than average size.. She put her feet up on the chair to make herself as open as she could for me. And then I started started to insert myself into her. Probably went a bit slower than I should have, but I was savoring the feeling. She let out a quiet, "oh my God" when I was little over halfway in, and again outloud with a bit of a whine when she was finally at the base of my shaft. She'd let her head hang off the back of the chair by this point, so I slid two fingers under her collar to lead her head back up to me. We were kissing as I started to softly grind against her, her little whines making my lips tingle before starting to pull out. Wasn't the most comfortable position and I wanted her arms to be able to rest, so i rolled her out to stand up.. She was having a bit of trouble and her knees were shaking. I asked if she was okay, but she said to please not stop, so reached around her waist with my right arm to help her stand and inserted again. I could feel myself moving inside her; she was a bit lanky, so my cock made a slight bulge as it pushed in. I also have a slight curve, so was pushing down as I moved forward. Apparently this is where women tend to have their g-spot With my left hand, I started to fondle her breast again. She was leaned over her, my body against her back as I started to kiss down the back of her neck. We started moving in opposing sync once it really started, she was pushing back as I pushed in to make me go deeper. Was harder than I'd ever been before and started circling my finger to play with her clit. At some point, I felt a compulsion to stand, then grabbed a hand full of her hair to pull her back up against me. It made her whimper; could hear her repeatedly whispering, "please, please, please." I went harder. Her moans getting more intense as she started arching her back again except this time I could feel her insides tightening on me. She cried out and pulled herself forward, I pulled back to help her get off as she nearly collapsed to her knees. I stepped forward to catch her, but she turned, her hands still bound to the bed frame, and quickly began using her mouth to finish me off. She pushed the whole way, still moaning, my cock thobbing in her throat and I could feel where the collar was. It's where she focused. Couldn't hold back anymore, so pushed her head back to pulled out and ejaculated on her chest. She was on her knees, head hanging as she breathlessly laughed and let her bound arms hang limply. I fell to my knees to join her, one hand on her hip and the other beneath her chin to raise her head. She was smiling, almost crying. We both said, "I love you" at the same time and I couldn't help but kiss her again in response. We did more that night, a lot more. Didn't know how cute reverse cowgirl could be with both hands interlocking fingers.. But think that should suffice for now.
