Eventually the Doctor returned for a set of test to check my condition, I was poked and prodded and scanned and so on. I asked about my new arms and w...y they just did things at random.The doctor explained that my brain was still in the process of rewiring my motor cortex to cope with my new limbs. He told me that with practice, they should eventually be as functional as my original arms. He recommended trying to use them as frequently as possible to speed up the remapping of nerve connections. Mom's cry turned into a gasp as she spotted the bulge in my pants, staring as my cock tried to rip out of my pants. Her face went red as her attention turned back to Trish as she slid her finger inside mom's wet pussy. Mom was shivering and whimpering trying to fight her lustful urges until she grabbed Trish's hand. "What are... uhh we doing? We can't... this is wrong uh... Danny's right there." Mom panted. "He doesn't seem to mind." Trish said passionately glancing at me as she continued to. .I wanted her...needed her! But, I let her do it her way. She scooted as close to me as she could get and then she put her arm around me and started to nibble on my ear as her other hand was slipping inside my shirt..touching, teasing my nipple, flicking it with her fingertip, pinching it gently. Ohh myyyy, she then unbuttoned my shirt down to my stomach and as soon as she pushed my shirt out of her way, I felt her hot hungry mouth biting my nipples, hungrily toying with them...teasing me. I. She was wearing a bright orange bikini, the top was a triangle style and it shows off just enough of her thirty four b cup tits to be sexy. The bottom was a Brazilian cut and shown half a cheek, the bright orange really popped next to her dark tan. Jeff and I both whistled as she did a slow turn around to show off. Andrea asked it she looked OK? Jeff said good enough to make every man at the pool hard. I agreed. After an hour of sun Andrea told us all these men looking at her has made her pussy.
