My parents are both professional people and work and attend a lot of meetings and stuff, anyway this leaves me at home alone quite except for my dog Benji, (a rather large german Shepard) leaving me and my boyfriend to have fun! and to be on our own, one night my parents were away ( I was 17 at the time) so he stayed over late getting in some food so I didn't have to cook anything! we made love as usual but without the condom this time as I was expecting my period.
Anyway this night after having sex with him I was feeling tired so I said I was staying in bed and if he didn't mind to see himself out, he left and I just lay there relaxing on top of the bed, benji came in too as he could go where ever he wanted in the house, I must have nodded off, not for long and when I woke up benji was licking the top of my leg as I was laying there completely naked, I got up sitting on the edge of the bed stroking his head and all of a sudden he jumped up on top of me! I am only five foot 5 in my stilettos and I was no match for him, as much as I struggled to get him of me I couldn't.
I tried using my legs but it was no good and all I succeeded in doing was letting him between them, i tried desperately to push him off but I just couldn't lift or move him, his paws were right up underneath my arm pits and he had me firmly locked down.
I tried closing my legs too but couldn't get one underneath him, then he started to thrust at me, you can't imagine what was going through my mind, all kinds of panic I was scared beyond believe, he was thrusting away and I could feel his cock hitting my leg, hitting my crotch until one of them found my vagina, I was screaming at him, benji no no but it was no good, he had me and wasn't letting me go no matter what I did or said.
I just had too lay there while he thrust inside with me terrified, I thought ok this will end in a minute when he realizes I'm not a dog but I was wrong, his thrusting calmed down, I could feel all his cock inside me, he was so big I could feel him pushing up against my womb and he was getting very tight inside me, I had calmed down, there was nothing else I could do!
As we lay there I could feel him ejaculating inside me as his cock twitched in me but there was something else too, I was beginning to react sexually to him, as he pumped his cum inside me I had an orgasm, a big one! in fact my first squirting one! and felt myself involuntary pushing up against his cock as wave after wave hit me, we must have been there for at least half an hour, until he was ready to let me go, and when he did finally get off me he licked my vagina for the next five minutes as I could not move!
When I did finally stand up there was a flood of his cum came pouring out of me and at that time I felt dirty and abused and in fact I felt like killing him, I went and had a shower and cleaned up the mess of which there was a lot!
Over the next few days I was able to think about what had taken place, he had not hurt me, although it was extremely physical, and he had given me the most intense orgasms of my life! I looked up on the net as to why he suddenly got tight in me and found out his knot swelled up preventing us from separating, and I was during orgasms pushing up against him! in other words I was enjoying it eventually!
I was a little scared the next time me and my boyfriend went to bed in case he noticed something different, but he didn't, I was just me but I wasn't finished yet.
A few days later my parents were going to out all night, staying in a hotel, I made an excuse to my boyfriend I wasn't feeling to well and just wanted to go to sleep alone to get rid of it, he said Ok I'll see you in the morning then and left early, I had to know if what I eventually felt that night was real or not.
I gathered up some towels from the dirty laundry and put them on the bed, benji as usual followed me upstairs and into my room, the only thing that different that night was that I didn't have my boyfriends cum inside me, I took off my panties and called benji over, as if he needed an invitation after what he'd done, he came right over and put his head between my legs licking me, his tongue felt so nice and parted my small lips so he was licking my clitoris direct as I felt intense pleasure, benji licked me harder and his tongue penetrated my vagina, and I came! at least I could control it to a certain degree and after five or so minutes of this, I deliberately opened my legs wider and lay back, benji repeated what he had done the other night but this time with my permission.
As he thrust his cock I helped him this time trying to move into a position where he could find me better and he did! my willing vagina excepted his cock this time with no fighting, instead I stoked him while moving closer to the edge of the bed, this time though during his thrusts my orgasms happened all by themselves, I squirted my cum all over his cock and they kept coming one after the other, and like the time before he eventually stopped thrusting as his knot stretched my vagina locking us together, I could enjoy his orgasm now as filled me up, squirt after squirt and very hot! much hotter than my boyfriend and about a 50 times more too, we both lay there cumming in and on each other and when he let me go I felt totally satisfied sexually.
Benji was loyal before he is even more so now, he is so very protective of me especially when we are out walking and there is another dog! but I know why!
Since that night we have regular sex, no one knows and he can't tell anyone, and I ain't saying anything, he is such a good lover, and totally secure! even though my parents think I'm in the shower all the time cause the towels are always in the wash when they come home!
