Hey Bob, I think I can help. I apologise in advance for the explicit language and graphic images

If you want the girl to enjoy having sex with you and probably even have stronger feelings for you, yes you should get her off.
With regards to the breasts, lick her nipples and suck them hard. More importantly, bite her nipples a bit, she will fucking love it if she is the kind of girl who likes nipples play (which she says she is), but be careful with your teeth. Also, try sucking her breast (so not just the nipples) into your mouth, as much as you can, and then lick her nipple while her boob is in your mouth, and when taking her boob our of your mouth, suck her nipple with just your lips (no teeth) and stretch it as hard as you can through sucking and then let go.
As for her liking her pussy being rubbed, fuck her sideways (spooning position), and while fucking her pussy, put one hand on her clit and start rubbing it. Very easy and basic. If you want to really give her a mind-blowing time, slide your other hand underneath her body and reach for her tits, then pinch her nipple, rub her clit, and fuck her pussy all at the same time.
If you want to feel more using a condom, try going slow, especially in the beginning. I find that I can feel much more when I am slow... I think you can also feel more when you thrust upwards rather than downwards, but I never paid attention to that so I am not sure.
Hope this helps
