Slow stroking a bish is one sure way to make sure she'll keep coming back. I might be old skool too much but I still don't get why a muhfuhkah would stick his dick in anybody's shit hole...
maybe, it's because some women, LOVE to get fucked in the ass.
trust me, those women do exist. i've had my fair share of them too.
many women have told me that the hardest orgasm they've ever had was while doing anal.i don't over-'analyze' shit...
(read that again). i just strap up, grab the lube and give her what she wants. 
pussy drippin n dude prefers da ass....
the anal penetration prolly making that pussy drip; i've seen it happen several times.
what happens is that AFTER you get in that ass a lil while, the pussy be on fire.
note: don't use the same rubber.
perhaps some of the bgol ladies will chime-in and give their $0.02
