Thank's to all for the videos and illustrations! Now I understand the biology of why Sarah went crazy with pleasure the first time I watched Thomas have her on our living room sofa on an early morning. Took Thom a bit of time to get his thick uncircumcised 10 inches fully inside, but when his big black balls finally began slapping Sarah's butt, she was completely incoherent with pleasure. She wanted his sperm so bad she grabbed his butt with both hands, guiding him to empty his balls in her. Thom was so excited he just kept cumming and cumming! WHAT a load that first time!
