Slut Phase With Family Friend

I'm 20, female, and have been getting driving lessons from a family friend who is male, mid-30s, and I've known him for most of my life. One day I met him at mine for a lesson, I only have a room in a shared house so not a lot of space, I had just come back from the gym so showered, then went to the room to change. He was lying on the bed and I had a towel around me, I told him I was going to get dressed quickly so turned my back to him, dropped the towel and put on my underwear and a dress. When I turned back around his head snapped away like he had been watching me, which I didn't understand. I've changed like this in front of male friends before and I'm sure they never looked so I didn't understand why he was looking at me change, but I didn't say anything and we had our lesson like normal.

For our next lesson I was wearing a light Summer dress that was above the knee and when we were done with the lesson and I had pulled up outside my flat he gave my upper leg a pat and a squeeze and said "Well done". My skirt had ridden up slightly and his hand was just touching the hem and lingered on my leg ever so slightly, which again must have been intentional. We went in for a coffee and a chat which wasn't unusual, and he told me I looked great in my dress. He didn't normally compliment me so I thanked him, and he added that it was "driving me a little crazy". I asked him what he meant by that, and he said he could just make out the outline of my underwear under the dress and it was turning him on a little. I blushed at this rather forward confession but couldn't help feeling a little intrigued. He was quite a handsome man, obviously looked after himself too, we were both single so I decided there was nothing wrong with a little flirting.

I'm fairly slim so I told him he shouldn't be looking at my butt, there's not a lot to see anyway, but he disagreed. I stood to face away from him and slowly lift my skirt up to just below my bum, then over my bum to expose my thong and gave a little wiggle, "this butt?" before putting my dress back down. When I turned to face him he was stroking his crotch area, an erection quite visible in his jeans that he was running his finger up and down. He motioned for me to sit beside him which I did, he then took my hand and placed it on his crotch. I started to feel his erection myself, pinching it between my fingers, rubbing it with my palm to ascertain its general size, which appeared to be fairly large. He undid his jeans and pulled them down along with his boxers and his hard cock sprung out. It was long, thick and veiny, unlike any I had seen in real life (of which there are not that many). I gripped it by the shaft and continued to feel it, "you're quite big" I told him. "Have you had one this big before?" he asked and I shook my head, not really wanting to get into my limited experience. I mean, I've had a lot of sex, but only with two steady boyfriends so I haven't had a wide variety of penises.

"It won't bite" he laughed, as I continued to idly play with and fondle his cock, "why don't you give it a kiss?" I felt self-conscious that I wouldn't be very good as he had clearly had a lot more experience than me, and I've never tried to please something this size, but I decided I should go for it, why not? I warned him I might not be very good, then bent over to put my head in his lap, holding his cock in one hand I guided it into my mouth and started to go down on him. "No, you're good" he purred as my head bobbed up and down, trying to go as deep as I could, occasionally gagging or spluttering. I soon found my stride and felt his balls as my mouth worked his cock; his breathing started to quicken and with some sharp panting cum started to jet into my mouth. I kept my mouth still and wanked his shaft until the jets stopped and I was able to gulp his semen down. He said my blowjob was actually really good, that I had nothing to worry about, and given he had cum in fairly short order I was inclined to believe him.

For our next lesson I wore another Summer dress as he seemed to like those, and picked out a sexier set of lingerie too, surprising myself somewhat that I was doing these things. Maybe he'd just wanted his dick sucked and now he has he's lost interested, or maybe he regrets what happened in the cold light of day. But if something did happen I'd want to be prepared. After our lesson he asked with a grin if he could come in, and I said he could. He followed me to my room as I did my best to give a sexy walk, sure he was checking out my bum. In my room he wasted no time at all in being forward. He brought me in for a kiss and grabbed my ass as he fumbled my dress off onto the floor, my carefully picked lingerie soon followed and I was on the bed completely naked while he undressed too. Now seeing him fully naked he did have quite a sexy, toned body. His cock had such a powerful erection, thick and curving upwards. He spread my legs and started to go down on me. Flirting was out the window, I was now about to get fucked, so I decided to just lie back and enjoy it, we weren't doing anything wrong, and enjoy this I did. He gave very good oral, mixing in a variety of techniques and finger movements.

When I was sufficiently wet he took a condom from his pocket, unwrapped it and rolled it on. Kneeling between my legs on the bed he guided his cock into my pussy, I covered my mouth with my hands to mask the gasp. Size does indeed matter, his cock felt great inside me as he slowly fucked my shaven pussy, intently watching his cock slide in and out of me. "That's so fucking good" I encouraged, grabbing to tweak my own nipples to heighten the pleasure. At the same time he rubbed my clit with his thumb as his cock plunged into me, bringing me to an orgasm.

His cock was still hard and sheathed in the condom, glistening from my pussy juices. He commanded me on all fours, ready to receive him doggy style. This was something I had never done with a guy until after a few months and some self-conscious feelings kicked in about him looking at my butthole, but he didn't mind at all and eagerly entered me from behind and fucked me hard and deep. My insecurities soon disappeared, even not minding when he spread my butt cheeks to completely expose everything; this was the first time I've been naked with him and there was literally not an inch of my body he now hadn't seen. We fucked doggy style until he withdrew, took the condom off and came in shots across my back.

This was the first time I'd had sex just for the sake of it rather than in a relationship, and it was good, I enjoyed it and decided to continue to enjoy it. Not only am I having great, wanton sex with a guy with a good body and big cock, I'm getting experience and really loosening up my inhibitions with things like dirty talk, sexting...I tell him things like to fuck my c**t with his massive cock...I masturbate in front of him, use sex toys in front of him, we shower together, all sorts and no-one in my family has any idea about the pounding I'm taking behind closed doors....I'm having a great time :)
