my live in Gf moved out a tow years ago. would visit on the weekends and had an auto accident. She is wheel chair bound for life now. As good as she will get. She ask me to take her to the house for a weekend. I did and kept her for the week. I had sex with her with some precautions. She could feel nothing but the oral sex she gave me. It did not feel like before by a long shot.
She tells me it makes he feel like a real women again. I do not want her hurt. Though I enjoy the sex, I feel guilty.

Am I taking advantage of her??
Should I stop??
Should I keep doing this??
Should I get her BC injections to prevent her getting pregnant??

She ask her friend Lisa to join us. Wants to be part of a 3 some like we did before.
Should I do this??
will this upset her to see Lisa ride me??

I am so confused.
