Should I Or Not

My niece Kr's best friend Sol, whom is a lesbian wants to have a baby before she gets much older and decided that she wants me to impregnate her. I have known Sol since they were both 16 (now 32). When I found out about this, I asked her why she wants my seed. She told me that since unlike most of her male friends, I have always accepted her sexuality and never once judged her on such. After a lot of thinking and discussion, I finally agreed and we got together this past weekend at my niece's place. Figured we would head to this motel a few min drive from my niece's but Sol wanted me to fuck her right here. I started to say no way but she told me that Kr wanted to play a small part in all of this. My head was kinda spinning at the thought of my niece watching me fuck her best friend, but I was getting very horny at the thought of it, so we all ended up in her room. I've seen both of them in just their bikini's many times and they are both extremely sexy. Both about the same height with great legs and asses and small perky breasts. Sol and I got naked, laid down and started to explore each other. Kr sat next to us and when she first glimpsed at my cock she let out a rather large gasp. A big smile came across her face when she mentioned that she has always wondered how big I was. Sol was obviously very horny as well and when she spread her legs wide and back, my knob was rubbing between her puffy pussy lips and just as I was about to slip in, Kr reached over, wrapped her hands on my dick and guided me in. Wasn't long and I was balls deep, fucking Sol like crazy when Kr put her face between our legs and started to lick my shaft as I pumped in and out of her friends tight twat. Few min of this and I filled Sol's pussy with one helluva huge load. Never came like that before. Now, its a wait and see game. Thinking about this coming weekend now. Gonna be a blast in more ways than one.
